Why I Don't Sell Motorized bikes. 

This video is intended for low budget builds (buying/selling). There are high end "Tank" builds out there that can survive most buyers, but not for 300~ dollars... Keep an eye on my "Community Post", I'll be asking you all what you want to see next.

I built my first bike when I was 10 I’m only 13 now but I totally agree just build a bike it’s simple not to mention cheaper and just gives you an understanding of how motors, bikes, and motorcycles work.

Anybody who's had a motorized bike knows there is more time spent working on it than riding it.

I've bought and sold two and it's quick cash but you feel guilty knowing that someone's dreams where crushed by China quality motors

These videos are damn near movie quality. Keep up the motorized bike videos everyone loves them.

After my experiences with these motors, I won't put another kit together without completely tearing down the motor and ensuring everything is cleaned, oiled, and sealed. It's even worth making sure the piston is oriented the correct way. If you're not sure, just move the piston manually until you can see the rings through the intake and exhaust ports. If you can see the small pin where the ring ends join through either port, your piston is installed backwards. Sometimes a small arrow will be etched into the piston top - this should point toward the exhaust port.

Good advice. I had nothing but headaches and lots money lost trying to sell these for profit. Now I ride a 63cc friction drive daily and love it. I’d suggest some cardboard on the grass or any work area. Helps me a-lot when nuts and washers get dropped. Keep the videos coming 😀

These bikes arent for the feint of heart. Build your own then you know.

Interesting, I bought a used Road Master 80cc gas bike and it took me on an 80 mile 7 hour ride to Chicago and back home on one tank of gas, by the time I got home the break cable was extremely loose that there was basicly no breaks, I still have the bike and after tons of issues with the carb idle screw turning by itself, front breaks completely breaking, chain breaking a couple times, back tire popping, the broke the cap on the original carb just by trying to tighten it, also for a couple months I was running way too much oil in the gas mix and after all of this the bike is now running great, I understand how the bike works now and how to safely ride it, I would say overall I had a great experience buying my first gas bike used for $315 + $22 for the Uber ride I had to get to go buy the bike, then I road it back to my house lol.

I personally enjoy tinkering on my motorized bikes. It seems to make riding them much more exciting…especially when they work properly.

“Tires lookin a little flat” **takes another look** “Nnnnah it’ll be alright” Hahaha that’s literally every motor head ever

Just finished my first build and appreciate all this in-depth information for future. Love all the videos

I tell people the same thing. If you put it together, you can do the maintenance. Yes, these engines do vibrate, and WILL shake EVERYTHING lose. The need to go over the whole bike with a wrench, after going out of a cruise. Most have no idea what a torque wrench is for let alone how and when to use it. Torquing of the head. Secondly if I build a bike and some takes it out and something goes wrong, I would be liable. So, the easiest and safest is to just say, "NO", build your own. The hardest thing in putting one of these "kits" together is getting the rear driven sprocket installed straight and true. Everything else is pretty simple. The removing the slag out of the cylinders ports is the next thing that is hard to describe to a non engine guy. To many people may want one of these but they don't want to try to do it for themselves. They seem to have it in their heads is it's handles like a car. If they put in the key and turn it, if it doesn't go VROOOM it's broke and have NO IDEA on how to fix it. I recommend for anyone starting out is to go online buy the cheapest "kit" ( $99 )and put it together. This is because it's the easiest way to teach anyone on the operation of Gas Bikes. I will oversee the build and lend assistance but I want then to build/assemble their bike. Upgrading to a "Better" engine is then a pretty easy thing to change out. ($140 for a Stage 2 engine). I am running a Stage 2 engine, balanced crank, Hi Compression Head, Tuned pipe, Big Box Reed, Hotter Ignition, hotter plug. I've been tinkering with the Main Carburetor Jets to get this engine to run in 2 stroke. 92 oct gasoline mixed with Stihl Chainsaw Premium Oil, @ 30 -1. With a 44 rear sprocket, flat ground, no wind, short bursts, 43 MPH, likes to cruise at 27-28 mph. One last thing....these engines perform the best when they are warmed up completely before hitting the road. Start the engine, let it idle. touch the head with finger as it warms up, when you can't keep your finger on the head it's warm enough to run.

I would say the easy answer is to give the buyer a sheet that tells how to properly care for and maintain the bike. Have two copies and make them sign it. One copy for each of you. Then you offer maintenance and repair service for a fee. Just like any vehicle dealership you make money off the sales and service. I would also not only out the bike together but break it in and then maintenance it before you sell it and charge more. Or alternatively you could offer either option at two different price points. One to break it in and the other without breaking it in.

I have built and sold many bikes. I ride all new builds to make sure that the motor is broken in correctly and all parts are tight. I use quality parts a nd have very few problems. I educate my customers on proper care and maintenance. My shop does all repairs and yearly tune ups. And lastly, l charge alot more than three hundred dollars for a well built vehicle.

Now this EXACTLY sums up how one of my friends tore his up and broke a bunch of parts out of frustration. I spend so many hours into something as small as the old bushing of the Phantom 85. I mean I get frustrated but I'm not going to break something I've spent so much time on. You have to know your stuff before you buy one!

I agree with your analysis. A friend of mine bought a used one once and he knew nothing about it. He brought it to me and I fixed it,,had it running and working perfectly. He came over and I started telling him how it worked and he didnt listen and just took of on it. He went speeding out of sight and all I heard was him crash. He came carrying it back with a scrapped up leg and broken finger. He took off full blast not knowing where the brakes were. I believe he hit the kill button to stop,,,and as soon as he let up on the button the bike started again and took off while he was turning. lol

I wish I saw this before I sold my two bike builds😭😭

10:45 someone’s rod knocking 😂😂😂

bought a motor, been watching your videos. I love the way you get into it with repairs and little bits of knowledge that comes from years of riding and fixing. just awesome

Ha ha, Yes Mr Hover, the idiot you loaned it to proved the old adage, "You can't fix Stupid" is still true! That was good wisdom you shared. The economy motorized bike sales is not for profit. I wondered why some bikes were so expensive. Then as I examined them closely, I saw they bought high quality frames to build on, or modified good frames by welding in specialty parts. Now, the bike is no longer bolt-on but custom, inc. painting & boom! Big Price. Thanks for speaking the hard truth! You may have saved a budding builder a lot of frustration. Cheers.

These bikes aren't "vehicles" in the usual sense. You don't just buy one and flog it for 3-5 years without giving a fuck. This is a HOBBY, people. You buy one of these bikes/engine kits to tinker with and entertain yourself. Yes, you can ride it to work, avoiding the police of course. But, it's *NOT* a late-model Toyota Corolla.

Your channel is growing and you deserve it. Your production quality is perfect.

On mine, Maintenance includes re-tighten engine mount nuts, chain tensioner loose often, exhaust pipe comes loose. Need to step up all washers and nuts. Double locking nuts I use(big improvement) i ONCE ran low on oil, engine siezed. Took it apart ,buffed insides to fix. I learned my lesson. Suggest nail proof tires and DOUBLE brake handle.(life saver)

Everything you said sir is absolutely 100% right I would add I wouldn’t sell one of these bikes I built because they could get hurt and then sue you🤪

After decades of improving motorcycles and car there should be a company that does a really good job making motor bike kits. What are the best kits out there?

I’m a tall guy like you when I work I also sit on a bucket👍🏻🥴✌🏻😎

I bought my 1st bike. But it wasn't a average build it was a very nicely done Schwinn with a Springer frontend upgraded tank custom flaring (2 great panels both sides of top tube) and a flying horse motor tuned/jetted carb for $250 looks like a board track replica Tribute bike.. and im happy with it still even now that I've learned a ton built a few of my own. The idea was to buy 1 fully built study it learn from it build my own to learn and go from there. Had a good head start since i also build scooters/mopeds

Yeeeeyeee 🤘 la hover ma guy love the video and the tips is what tell people that wants to buy a motorized bike know what your getting your self into

spidy senses with that falling wd40 can

The things you say in this video also apply to chainsaws I can't begin to tell you the stuff I had to repair when I got them back!! I just stumbled onto your channel but I mainly have seen your older videos and I like them. Have you thought about building a 4stroke bike? You do nice bike videos it would be interesting to watch . Thanks again nice video

I build and sell motorized bicycles in Tampa. All i can say is people as a whole are dumber than a box of rocks . They all call me 700 times a week wanting a motorized bicycle but only have $20 to spend . And people thinks my shop hours from 8am- 4pm mean im suposed to be open at 1 am . Thats when the phone rings the most . Or they buy a motorized bicycle and totally think it is suposed to out run the fastest production motorcycle made . Or they buy one from someone else and they break it but it's my foult and i have to repair it for them for free .or they think these bikes have a forever warranty. It realy is amazing how stupid people are and no matter how many times you tell them these are designed to be ridden at 20mph every single one of them head out down the road engine never been broke in wide open full throttle all the way .and call 10 minute later I'm on I-75 and it won't keep up with highway traffic you robbed me . Ya it is a major head ache and you deal with the stupidest people on the planet.

When I’m pulling chains through I push it up in there with my hands till it comes down the backside then I take a small Alan key and hook it in the link. It works really good

Thank you for filling me in on the specifics of these bikes.

God bless you for all your good content and education about motorized bikes

I've built 2 electric and one with a chainsaw engine. I've got more hours into them, making them nice for ME, than I could charge for. People always ask why I haven't started building/selling and the primary reason is customers that don't know what they are getting into. I'd sooner disassemble them and throw them away than hear back from some jackoff that didn't know what they were doing and ruined them.

almost 2 years later and im still trying to figure out how you got the bike started by lifting and spinning the back wheel

Did you have your "friend" watch this video? Because maybe you ought to. There's a motorcycle book I remember reading from the 70's that's very first sentence in the book stated, "If you don't know how your motorcycle works, you have no business riding it." No truer words have ever been written.

I use a headlamp at work. People don't realize how much easier it make doing repairs when your hands are free and your light source goes where your looking.

Love the way you put that about the people having to learn about their motor bike.. I believe this should also be included towards vehicles.. because not a single person knows what the noise is that their cars making before the wheel comes off or say the brakes go out or any of that not anyone pays attention that cuz they got insurance to cover for ... I think a person that drives their car and they're wheel comes off for their brakes go out I think they should be reprimanded into a fashion there's a lot more than just getting covered by their insurance say maybe all Learners course to what a vehicle's noises sound like when it's about to have seah ball joint go out a tie rod or the upper strut mount a sway bar.. Your rear drum brakes.. No one pays attention to this because they got insurance I think anyone that has an issue in this fashion should be reprimanded by the courts to take a learner's course

I have the A80 motorised bike kit

Dude had me cracking up , his description of the situation was hilarious 😂.

I couldn’t stop laughing most people are not handy. I had to learn to fix my bikes and go carts when I was younger we had no money to pay to get them fixed if we wanted to ride we fix them ourselves

I know the tight fit frame problems. I got a Mongoose Mack that I motorized, had to put a short intake on it to fit the carb. Not to mention I have bolts up front longer than the factory engine studs to fit my triple forty to my bike.

I built and sold around a dozen motorized bikes for profit before I realized it was wasn’t worth it. Like the man stated, the profit margin relative to effort wasn’t worth it. Not to mention the messages I would get from pissed off buyers asking for some kind of compensation only a few days after the sale. I remember receiving pictures from previous buyers showing a snapped frame, missing screws, broken spokes, etc. I felt bad for them and it was difficult explaining to them that this is what inherently comes with a motorized bike. It got bad, the final bike I sold pushed me to quit because the buyer literally threatened to kill me over $300. You’re probably better off drug dealing then selling motorized bikes (sarcasm).

The chain that you said was in need of replacement! He anyone saw the rusty chain on my old amf 8 years ago when I bought it, they would have replaced it but me, myself, I just oiled it and worked out all of the stiff spots! It's been so long ago that I don't remember what I used to oil it but it's still on there and you would never know!

Please keep making motorised bike videos I really like them. Buying engine bikes assembled ruins the whole experience. I made my bike myself and had to deal with all the issues (there was alot) but now I can deal with any issue on my bike and it is reliable because I have prevented any issues that could happen. The bike is 25 years old, has no suspension and is rusty but I ride it flat out all the time. Yet it is still reliable. Buying a bike pre assembled is stupid because you don’t know how to fix it or the issues which are specific to the bike.

I wonder often how certain people make it through life. Even without a chain saw motor bicycle to work on.

I just bought a motorized bike like yours in the video for $150 and I knew it had issues as he told me. With that said, I will tare it down to put on a Cruiser bike frame that I picked the cruiser bike up for $25. It will be my winter project for spring time so I can upgrade it every month little at a time. At least I can get a feel for riding one as I HAVE NEVER DONE THIS before. LOL. Got my crash pillows just in case. He said it takes an 18:1 mix as I have seen many take a 40:1 mix. Still learning and watching RU-vids.

Madmatts custom motorbikes. My last two stroke went 50 mph on a Fat tire bike. I sell suspension upgrades, you name it. Ported milled windowed ramped third transfer port and 24 to 26 mm carburetors with dio reeds. My last four stroke fat Moto I put a header pipe on it remove the governor replace the carburetor and put a smaller sprocket on it. 12 gauge spokes.

i build and sell them to make some money and it’s great, i get them from a website in my country who gets them from china and strips them down and greases and inspects everything and i’ve never had a problem. i’ve recently found a bike i built pop up on facebook marketplace about 2 years after i built it and it still goes great. i’ve sold about 15 so far and no one has came back to me saying it has issues

You can prime the head with a drop or 2 of fuel through the spark plug hole, put the plug back in and it will fire right up.

Bikeberry sells the switz-cruz combination However the motor and bike are delivered seperate

I take mine on 10 mile, 35 mile trips frequently. With the port work I do on every cylinder and my aftermarket head, exhaust, 36t sprocket I get approximately 200 miles of mostly highway trips out of a top end. I recently found the best chain so chain breakage is not a problem anymore, but usually it's a ring that goes. Last time, I lost my wrist pin bearing I had used since the engine was new two years ago and four or five top ends ago. I'd say I'm pretty much a motorized bike veteran at this point and I gave up on trying to make a business out of it the first year! Too much labor for too small a profit margin.

Dang those no bike building, high revving long periods of time, no bolt tightening bike breakers, just baby it and it will lasting long time

Thats partially true. There are folks looking to buy a motorized bike to educate themselves off it as well. Id say its a decent starting playing if youre wantjng to learn abojt combustion engine and work your way up to bigger and better and more complex. When i put my 100cc kit together it wad i deed a learnjng experience.

Very wise words my friend, love your channel!!

I like your bike stand!👍

Hey there my name is Tim Nicholson, i live in NLR Ar. Ive watched several of your vids and believe we see things along same path. Anyway bout to rebuild Flying horse 80cc. I tried damn jackshift had 5 gears and did what was suppose to just never got top end. I am great with building things...not worth damn on computers. Was just hoping to pick your brain in avoiding some mistakes iv made along the way. Seller wrote "if you need instructions then dont buy our product. I thought how cute. They werent lieing. No packing list, nothing. Heres a shit load parts that may or may not be all included. Do the best you can. My start. I have e-bike 48V 1000w with .999mh battery. built WW1 replica 4 stroke i love. but put some xtras in this 2 stroke. 4 stroke does 71 kph. if my math still good believe bout42-43 mph. Satisfied. Sorry wrote a book. Looking for pitfalls to avoid if dont mind sir.

Is that a Day Vision headlight on your head?

how i make money selling bikes... lets say i built a 200cc cruiser bike off a full suspension super cycle hooligan had 21 inch and 19 inch dirt bike tires on it... cost $1700 to build it. sold it with a worn out clutch spring. but how did i make money on it? used it to get around the city cheaper then a cab even cheaper then a bus ticket. and after getting some attention from building it and driving it around the city for an entire year with no problems... an opportunity came up... so i drove it 250 miles to a even bigger city and was sold something worth way more then the bike... so i drove the 5 hours to get back home with a 120lb engine strapped to the back rack... i got around on a $100 pawn shop bike, then did $1600 in work to it... to then use it to drive a vary long way to pick up a dirt bike engine that a dealership took as a trade in. i put in $2500 of work into it to pick up what i thought was $700 of dirt bike parts from 250 miles away... once i got the dirt bike finished i sold the 200cc bike for $300. I made $6000 in material wealth by using that 200cc bike in a progressive manor. BTW i made a video of the 200cc bike i made, but you'll need a welder to make a copy of one... welding courses can be vary expensive but were i live and the school i went to, i was tough welding and lots of other things as a mandatory courses needed to take so i could graduate and get a diploma. writing was one of many things, separates one from the other vary easily. :)

I built one of these bikes my self on a 20 inch sting Wray frame, but I do buy pre built ones just cus they were a good deal I bought one for $60 at a pawn shop clearance, I only bought it cus it was a good deal and it was I got lucky and I didn’t need to do much work to it

now that was really real! thanks for sharing that.

lent a bike to a friend to go put in job applications and he blew it up because he was going flat out around town in 90 degree weather. in his defense i didn't thoroughly explain to him why he should baby the thing and go wide open in short spurts. but he knows a little here and there about working on cars and all that. so i just expected him to assume that cheap china doll motor = its not a dirt bike. nope. not only did he cook the thing, he decelerated it a ton so it was continuously starved of oil and ignored the fact that the clutch screw was almost completely backed out. so the clutch is gone to. so instead of rebuilding the motor and risk the casting being cracked somewhere because of how hot it was getting, im just gonna buy a phantom 85 gen 2 and throw that on it. still wont confront me at all about it either which pisses me off even more.

Great tutorial. Really. Smart guy.

Random idea, but lock wire these bikes would hold up so much better to vibration, honestly give some piece of mind

I've got to say this. In California you can be sued for selling or loaning your bike to someone if they get hurt, die, or hurt someone else or property damage. Check your local laws. Even if you made some parts for someone. Be careful before you do anything of that nature.Seek legal advice. Great video.

I made the mistake of buying an 80cc two stroke motorized bike from Facebook marketplace, I wish I would have built it cuz it was sloppily put together and took a ton of maintenance anyway.

The big problem is that these are kits. The strength you get from welding everything together snd using heavy-duty parts meant to endure vibration is just not given to you. I think you could use these motors for a product, but man you would have to know what your doing and be willing to test every part.

Too bad your not in Florida…because I would give you the remaining spare parts I have….I got like 12 chains…2 are 415. I got 3 carbs….2 engines, 4 CDI, 3 gas tanks, tons of throttle cables, and clutch cables, 5 CNC hub kits, 11 stock sprockets, and mounts, 7 beach cruiser mounts, 2 motto stands, 2 jack shaft kits, and 3 side chain guards. I got out the business, and got into E-bikes….they sell slower but I always yield me a $150 to a $250 dollar profit, and no issues with the buyers.

I drive 10 miles to work on my bike mainly going full throttle, not much problems through out the 6 months of me doing that, haven't replaced my engine yet.

Crazy tho we used allot of lock nuts and a variety of washers so it fixes it all, If we didnt cruise on a stock engine it could run hard for some time. A different head and multiple things helps with cooling. Full throttle it's possible because most people will it's not avoidable you just got to keep fixing it if someone is the way they are... Mechanic work is hard but anyone can make it work for the impossible things to happen. Bending rims id be avoiding people like that, It is even better that you do know how they did it so you can avoid them.

i feel your pain and the poor bikes pain .

if you're in the Los Angeles area there is a bike shop near USC called "Primos Bike Shop" and they are the only shop in LA i know of that work on and sell these kinds of bikes. The quality of their work is amazing and cheaper than most normal bike shops. I highly recommend them if you're having trouble with your bike because they will get it working again. also, they sell upgrade parts like mufflers, larger tanks, smaller sprockets, cylinder heads, etc. if you dont like waiting for parts in the mail. www.yelp.com/biz/primos-bike-shop-los-angeles

I sell them. For $300. Bikes are $50 motor kit is 120. They understand they are cheap and they may or may not keep working. I also show them how to ride em. But you are correct. They are going to expect perfection even at $300! And it ain’t gonna happen. Yea most people have no common sense. Your friend sounds like a beast. Lol if And when anyone comes back to me with a broken buy I charge $25 an hour to repair them. And again tell them what they are doing wrong. I also tell them it’s a bike so it will always need to be Maintained. I also put several miles on each one and then go and inspect it a second time.

Thank you for another awesome video. Can’t wait to see another video of this particular build. My motor / setup that I built sounds exactly like this!!! At 250lbs and mounted onto a Mongoose 26”, it can get me around. No complaints, and I don’t desire to go much faster. But you always want to perform a little better. Again, as this is my first season, what upgrades would you recommend to something like this? And, you are right! TLC is always needed for these kits, regardless though of quantity.

No matter how good I build a gas bike…people manage to still break them. The Kind of people not to sell to is people who want to use them for daily transportation. They think they can get on them, and flog the hell out of the throttle, they also don’t listen to a thing you say, and end up breaking them…I even provide a Manual that come with the kits, and they just toss or loose them’ the manual provide the gas and oil ratios’ 50:1 to break in the motor. I had one guy use only gas and the engine seizes…he blamed me for not explaining it’ Despite me providing the two-stroke oil’ I sell them with new engines and bikes, and provide the 2 stoke oil.. I had another guy bring the bike in ‘every time he gets a flat tire’ I explain in detail how to remove the back tire…AND HE STILL BROUGHT THE BIKE IN DUE TO ANOTHER FLAT…HE PAYS FOR THE LABOR….BUT I SIMPLY DON’T HAVE THE TIME’ I finally tell him he’s on his own’ some people are ignorant..I have set times I’m opened and close ‘9am to 6pm’ they end up showing up at 9pm..l get nasty text’ on my business phone’ cursing me for having to travel far’ I don’t care how far they travel….my rules are rules. I also refuse any returns…the bikes are tested every week for bugs in the build, I also ride the bike to prove they run. They left in one piece, and ran when they purchased them…I even put sold as. I never had any buyers break a chain’ I use jack shaft kits’ I finally went to e-bikes only’ gas bikes are a major headache.

Me, I tried to tell some people don’t sell their bikes 🚲 I built one ☝️ and the reason why I built one ☝️ is because some people didn’t want to give me a ride where I wanted to go but that bike got me there with no problem

Why you should sell them in refurbished condition or new condition.

Ive found with the spokless wheels and right tensioner, i have had better luck

What I’ve learned…. These things fall apart very quickly with misuse. I’ll be keeping this in mind. Hopefully an Al comp with thick ass down-tubes will work lol

Again..very well said..they are far from turn key and go.i could not have explained the situation any better if i tried. If u are not mechanically inclined u don't have any business owning one..

The same thing happened when I let a friend borrow my bike I got it back with the rear wheel spokes broken found out the idiot was jumping a wooden ramp in the middle of the street something a 10 speed racer bike isn't designed for.

Avoid wd40 for anything on bikes, it attracts dirt and grime into the components you spray with it. There is other industrial spray lubricants, but lithium grease for a lot of high friction applications or inside cables is one of the best.

And the 50 dollar Craigslist find and $ 100 standard upgraded China doll motor bike kit combination works very well... $150 =$ 300-400 When I say upgraded I mean the one with the Allen bolts instead of the Phillips head bolts the strip out so easily. I think a better title for this video would be lesson learned.

A 2 stroke motor is design to run with full throttle for a short while, then relise it fully for a few seconds, and then go back to full throttle. Half throttle cruising will Kill the motor.

What if you change up the motor and figure a way to weld an engine plate on the bike

10:55 Nice catch

I've got one that looks exactly the same, it was advertised as a 80 but people are telling me it's a 50cc, not like it matters I luv it it's so much fun, my chain has snapped twice an was goin to say all my bolts keep vibrating loose but I do tend to push a touch to much, but the biggest problem I've got is I'm from England an police can't wait to get their hands on my bike, I've took Chase twice an had another close call an i hav friends that hav faster electric bikes an the totally leagal

When will we see a electric bike kit?

I know what you are talking about when you said "people want to run wide open " had a guy tell me, he built this bike, and couldn't get it to run, so I looked it over and immediately knew he didn't build it he bought it from someone, the tank was full of dirt the fuel line was black, and it was a stock line, clear, and the filter (stock) was black ,so I told him it's going to cost about 30 bucks to replace everything from the tank to the intake, and then I told him that I will only charge him 20 bucks for labor ,so 50 bucks for all, he said okay,get it running......did all that and tightened everything up,and I mean everything! ,showed up to get the bike and only had 20 bucks, told him when he came back with 50 he could pick his bike up, and he got upset, so....I ended up calling the cops, and the cop told me I had to give him his bike, and if he still owed me money I would have to take him to small claims court to get it, that's why I don't fix anything else without payment upfront, love the video!!!!!

10:56 nice catch

A great video again

Have had countless issues of the engine having so much tourque it puts the wheel into the frame How do i keep this from happening

If you go to www.thatsdax.com they have high high compression cylinder head made for a moped that you can use for the engine and may other parts if if your shoping in the future

People sell motorized bikes where I live for 500 to 800 and it only costs 150-200 dollars to build the bike and an hour or two building the bike, it seems like it would be worth the time and money to build and sell these bikes atleast in my area where I live, and you can avoid the bolts/nuts vibrating loose by using red lock tight on all bolts/nuts.

Rule #1 never lend your bike, rule #2 never lend your bike, rule #3 repeat rule1 and 2. I motorize vintage bikes like the schwinn choppers, spiders, and 50's and 60's beach cruisers with suspension springs in front of the handle bars. I sell my bikes to businesses like bike & motorcycle shops or any interested business for display or collection. One customer had his orange county schwinn chopper mounted in his gameroom and looks beautiful all chrome w/red tone. I do after market engineering and replace better quality nuts and bolts, I replace chains with higher quality chains from Tractor Supply, developed a way to keep the tensioner provided permenatly bolted and keep it from sliding back and forth or sideways, and so on. I do advise the customer that they can use the bike otherwise as a daily ride, but requires constant maintenance and longevity of this kit is low. It's a hobby and I'm on my 40th build and it's my 11th orange county Chopper and my last build. Moving on to other projects.

You dont have to clip zip ties, you can use a knife point to pry the latch open, or just buy reusable zip ties

I don't sell motorized bikes because it takes so much know how to keep them running correctly.

Whenever I sell one I then distance myself from the buyer and let them deal with what is now their property. Thats what the guy that sold me my first bike did, and its the best way. Hard to learn to do what you gotta do if someone is holding your hand through all the problems. Plus its good to learn how to work on small engines like these, useful life skill.
