Picking A Motorized Bike Kit 

Category 1 Buyers: Looking for reliability Category 2 Buyers: Looking for cheap, but not trash.

Followed your advice. Went with the zeda 80. Strapped it to a cranbrook. Took my first ride tonight. It is pretty fun.

I still remember when these kits wer 85 bucks on eBay five years ago lol

You keep suprising us with your invaluable, information about, motorized bikes & mechanical tips from your mecanical skills, thanks, mr hover, say hello for you & your dad, on his age, & still ride bikes, say hello, from panama, joe.

I did 1300 miles on my bike from fallon nevada to green river wyoming and then back down through northern utah. I wore my back tire at about 900 miles and we took the kit out of the box installed them and then tested the bikes around the block once and headed out to highway 50 and on the road. It was a blast. My friends motor lost power between vernal and duchesne utah at about 1000 miles of everyday use pulling a bike trailer with gear the entire way. They stopped pulling up hill between 6 and 7 percent grade on the road grade of steepness.

got a bt100 recently, it goes real good and has really high torque. you pop the clutch and the front wheels up. power is really good for a motorized. one downside is it has 4 mounting bolts on each side and one has snapped. the intakes and stuff are just different shape but still fit any regular carb. the exhaust tho is unique. i honestly recommend the bt over any other kit. i’ve had a really good experience so far.

I followed your advice. I got the Firestorm Zeda 80 kit and installed it on a Huffy Nel Lusso. This is my first ever motorized bicycle build. I only ran into a few minor problems but they were pretty simple fixes. The only issue I'm having with it is that with the stock NT carburetor that comes in the kit, it's a little bit hard to start when it's cold or after the motor cools down for a while and at wide open throttle at higher rpms, the fuel mixture leans out a bit at times. But when the motor is at operating temperature, it runs really well. These issues can be solved by swapping the carburetor out for a higher performance carburetor. Thank you for the advice. I really appreciate it.

I bought a pk80 kit, a very nice little engine. I had to adjust the clutch nut because it was too tight for the clutch to disengage but that was my only "problem" other than the fuel line leaking because of user error.

Great job keeping me intrigued throughout the entire video. Even though I have had an engine for over a year now, I still wanted to see the recommendations of another builder with a lot of experience. Keep up the great videos and stay safe!

Went with the motoose for my first attempt at the hobby, I've had four scooters stolen in the last several years, against your advice and it's been a great kit, no leaks anywhere, came with old style petcock, rode daily for nearly 4 months now, had ment to put an engine on the bike when I bought it 10 years ago, you're video encouraged me to make the purchase and glad I did, a seven minute ride to work, and confident enough to ride back home to have lunch with the wife daily! Thank you good sir!

Thanks for being the light at the end of the tunnel for me buddy Much is appreciated

Seeutek makes some surprisingly good kits. I'm glad to see he talked about them

I chose a Grubee gt5a, motorized bicycle canada, alot of good parts, allen key`s not phillips, nice clutch lever, upgraded carb, easy install and so far so good

my first kit was that seeutek amazon one and I beat the crap out of it and it was great. But now I just buy an ebay engine only and turn it into a frankenstein engine like zeda used to make with a stihl ms660 cylinder and piston, I would highly recommend building your own frankenstein engine, shitloads of power and you can do it in about 1-2 days assuming you have the tools and know-how.

When you see those ted flags like Phillip's or JIS bolts on the outside, 6mm studs, etc.. you can bet that same substandard quality continues into the inside of your engine as well. Imo, the reverse is also true however to an extent.

I bought that first eBay kit. Unbelievably amazing. 8mm studs, great performance, and the g series head. Only issue is that the head nuts are stuck to the studs. Although new studs are cheap, and runs fine..

Great info brother I have the zeda firestorm on one of my bikes and i love it,i am gonna purchase the yd100 soon but wasn't sure about its quality glad you made this video now I know what path I need to take thanks again have a great holiday👍

Looks like I made the right decision going with BikeBerry 60/80CC kit with all the added upgrades in all black.🤠🇺🇸

Useful information well organized with visuals. New to motorized bike building and will definitely begin with many of the options offered.

Many thanks for the video, I knew that it would be very useful and informative when one of your first points was about the cheapness of the nuts and bolts on some of the kids and how is indicative of the general value of the kit itself. Have you considered recommendations on the actual bike frame to pick when you're considering motorizing a regular bicycle? As you know there are many factors to consider, including the size of the individual, the particulars of the alloy that the frame is made from ( an alloy with a higher amount of aluminium is more likely to bend or break, especially on the axle Forks) and how the style of bike frame affects the performance of the motor and the speed of the finished motorbike. Also any advice whatsoever recommending front and rear lights for a motorbike would be very useful. It's a problem to run the power for them from the motor, and outside battery is always too heavy, and the generators for regular bicycle like our way 2 delicate to be used at any higher speeds or greater bumps. Batteries that are held inside of a attached bicycle light will bounce out, and the brackets regular bicycle lights always break or end up sending your light flying off into traffic. Yet on a motorized bike in traffic visibility is a priority so sorry these problems is a big deal! Thanks again and keep it up

Rag joints are perfectly adequate with a stock or near stock kit. The biggest upside to the clamp on adapters is there's more adjustability side to side.

I bought a kit for 100 dollars on aliexpress and it is working fine so far

Just starting to look at this my criterion are... 1. Not made in China 2. Used on adult trike 3. Works in wet weather. 4. Pull or electric start. 5. Less than 50cc. 6. Not too loud hopefully.

I'm running ZEDA kits. Some engines that have the 6 1/4in, round "dots" molded into the cylinder fins that can be seen on the outsides of the cylinder. This is known as the "D" cylinder. These engines are simply ported a bit better. The easier that a 2 stroke engine can "Breath" the better it will run. Adding a tuned pipe and a bigger carb are a good starting point.

Amazon is my go to source for my motorized bicycle parts, because if things do not work I can always exchange, plus I can get reviews on certain parts. My jug is a one piece design, and I have no problems with it at all, I put an expansion chamber on it with a magneto upgrade kit and it, without any mods at all.

Me and my "West Virginia Motorized Bicycles of The Eastern Panhandle" posse 'LOVE YOUR MOTORIZED BICYCLE INTELLECT' so Please keep it Going buddy!!..

I bought the firestorm 80 kit. Worked great but all of these are gonna need a little tweaking and handy work. Not for the faint of wrenching or forum lurking

Fantastic channel, thanks a lot for the effort you put into making these videos!

I went with the Flying Horse epa certified engine from BikeBerry .....its been good.

I bought the 66/80 from Bikeberry. It was on sale last year for $170.00. I've ordered some additional parts from them since and have not , knock on wood, had any real problems with them. As I learn more though I am comfortable looking on other sights now if I need to.

I got a YD-100 as my first motorized bike engine, it has been a joy! i got it one year ago and the only thing i had to change was the piston bearing, i make ifood (kind like uber eats delivery) here in Brazil with it, like 8 hours a day and it`s just awesome, it got the toque, reliable (except for the bearing) and it got a decent fuel economy too!

I’ve bought the anbull motors at 14:40 and I can honestly say they are a good motor so far the only issues I’ve had is the sprocket I bought aftermarket hub clamp style DO NOT BUY broke four of my spokes and snapped two of the three sprocket mounts slips and chews up your hub pretty good went to the rag joint instead so much better it’s all about learning as we go.

More importantly on motorizing a bike it’s crucial to do it to the right frame many bikes aren’t built strong enough to handle the tourque and stress the engines put on the welds and frames

Betting this vidio gets a lot of views! A much needed vidio!

Makes me wish you had this up back in 2010 when I ordered my first motor kit. Was finding issues shortly after a few months of running it. Namely how the bults holing the head and jug down started stripping out. Probably that it got too hot and the stress caused it. Glad to found this afterword though. Good way to keep informed for future bike motors.

I spent the extra money and got the 4 stroke, as I planned on riding it to work every day, which I do. Over 100 mpg, fun to ride. Of course, people look at me a little funny when it’s 25 degrees out lol

Thanks for the what to look for section. As someone who lives in Australia none of these specialised websites are available, only amazon and ebay. Even then, none of the specific engines are available, so it was really helpful knowing what to look for.

I predict that based on the title of this video you will have more views than any video you've ever done. I haven't watched it yet. Gonna do a few things then dig right in.

I just read that that the 100CC engines are actually only 80cc for some reason. I do like what they call a 100cc with the big rounded head fins, both on top, and around the sides. It read that that head provides less vibration. I just want a lot of low end power myself, for hauling, and going up hills, and I would be happy doing 20mph at full throttle, which is actually a good clip on a bicycle.

The very first seeutek I purchased came with 6mm, the other 5 after that for building friends bikes were 8mm, never had any issues with any of those bikes.

I want to go, category 1 one, keep us update, with, category 1, thanks. Keep sharing.

I like how you referenced between beginner and somebody that has done this before I’m not an expert but I have dealt with these types of engines mostly two-stroke since I was about 16 years old and you are right somebody that’s just a beginner probably is gonna want something less maintenance I will also agree that a lot of the hardware in these kits does hold up pretty good but I will suggest trying to find something a little bit better quality just saying basic kit upgrade it yourself I recently put together a pretty decent bike it gets me where I need to go and my bike will run pretty fast just having a stock engine with a 42 tooth sprocket I believe not 100% sure But I also run a little bit bigger than 49 cc I would really like to here what you think about a 80/100 cc stock .

Great information sir I would have to say your first kit is crucial for getting hooked on the hobby get a bad one and you feel ripped off and discouraged pick a good one and you got bugs in your smile

My family & i, we are building 4 motorized bikes, we are glad to see your instructive, videos & experience, on trail, also, building these bikes, we are learning about them, thanks, say hello, joe.

Very informative and easy to understand everything the man says, this is good narrator and I can see this channel growing

Can you do a review on the Zeda 80 Performance Bicycle Engine Kit With Dio Reed Valve & OKO Carb?

This helps greatly! I'm overwhelmed.

I like my BT 80. It’s a power house and is very well made. I don’t know why you hate it. My mount studs have never broke off.

Response to the BT80 Although the intake is not a traditional as all China doll motors they cast the intake and open it right up, it's an oval port design angling downward the measurements of the port actually is 42mm. The exhaust port is alot bigger as weel, but still accepts your standard off the shelf ebay and amazon clone pipes. Been running the BT'S for a year now and with no issues except a few broken studs ( 6mm) , now upgraded to 8 mm Compared to my Grubee 66 40/40/40 it's got more torque from low right through to the top. The BT100 is even more a torque monster, I can wheelie with a crack of the throttle 😊😁😂

I ordered the f zero bike with dual brakes and the stage 4. Can't wait to ride

Thanks for the video. I just bought a yd100. Can't wait to take it out for a rip!

I never use the rag joint bolts that the kits come with. I use black Allen bolts, and lock nuts. Easier to tighten on the Fly because every bicycle multi-tool has a set of Allen wrenches on it

Great video. Great info. I might just need a softer seat for my bicycle in order to ride it more, but with the Lamborghini name on the side of frame, maybe a little 2-cycle noise is what it needs. BikeBerry BBR stock kit won out with the discount and free shipping. Will soon see if it works on this hybrid bike. Keep up the great videos!

Ive had 3 bbr stage 4 All of them were slightly different . One of them had really good crankshaft balance & is stupid fast The other two weren’t very balanced & vibrated Enough to want to change out crankshafts ....So I think it’s like playing the lottery.

wow someone who actually know what they're talking about, great video! could you do a video about how to make these as quiet as possible?

when buying on amazon, many sellers offer the item under ONE listing...that is very often the reason why you may buy something on amazon and receive a different version or color of the same basic item. This isn't so much an Amazon issue, as it is the individual seller, many of whom may sell items that they have little knowledge of. They get motors in stock, find a listing on amazon that looks like theirs but they don't actually do any research, and so they list theirs for sale under a listing that isn't actually identical to their motors.

Yaheeda G series with a head instead of one piece cylinder. That could be a beast.

Also be sure to explore ebike options as well. It's nice being able to rip around in near silence, it doesn't catch anyone's attention, so even less chances of people complaining to the police and deal with a meeting.

Noice now I can put the kit together with my friend

Don't do the Yaheeda G series just recently got that exact kit from Amazon. Magneto and Cdi were both dead Clutch shaft was shot clutch pads were all worn. Engine never ran after being installed. Go with one of the black 80cc kits if anything you won't be risking 150$

Got my 66/80cc 2 stroke kit off ebay even upgraded from 44 to 36tooth rear haven't had any problems runs great an I'll get the one off ebay as well might try the 4 stroke kit next build or electric maybe

IMO it’s cheaper in the long run to buy a better quality engine from the start. The brand new cheap engine I got was a joke just everything about it. Because everything was such low quality I decided to take it all apart after only a couple rides. The crank bearings were shot yes they were cheap but because the crankshaft wasn’t machined properly the bearings were basically pressed on so the bearing races were being preloaded which overheated the bearings and after making them fit properly the crankshaft had a ton of end play so I had to buy shims, I drilled the crankshaft to balance it because it vibrated so bad which is also terrible for bearings, the port timing was so bad I had to put about 4 base gaskets on and machine the top of cylinder down, the shaft with the big spring for clutch was machined really bad so i had to replace it. I did a bunch of work to it, bunch of performance things and by the time you add up money spent and time I could have bought a quality engine that was mint out of the box. Could buy a 212 engine from harbor freight, cvt drive/torque converter for under 200 bucks. Financially wise the cheaper stuff is a waste but if you like tinkering then it can be fun

I never new these kits existed until 3 days ago. Having never seen a bike here in the UK with a motor on it. I came across them on Amazon when looking for parts for my moped... Not sure if legal here, but sure fancy building one.

Hey, i already bought a really cheap 50cc from Walmart, but this is still a great video because I think I can anticipate replacing that engine in a year or so, and this video is really helpful in letting me know how to properly shop for these in the future.

Ive got the motor that the head and cylinder sleeve are one piece, yes a pain to mess with but it just keeps running. Got around 100 miles with no issue

PayPal doesn’t protect you as much as you think. Ordered a chainsaw, received a chain. After arguing with the seller who tried to get me to send more money, I put in a claim with PayPal. It was a total waste of time. They wanted me to provide a police report, really against a Chinese exporter, good luck with that. Just saying, PayPal doesn’t mean safe purchasing.

Very informative video. I am thinking of doing my first build and I am glad I found this video as there are soo many options to choose from. One question though. Is there a reason you recommend the Zeda 80 over the BBR tuning? If price is a non issue, would you say the BBR is the one to get?

I bought an 80 dollar ebay kit last year and its still running fine, the only thing i had to replace was the chain because it kept breaking.

I bought a kit from Amazon by anbull and it was pretty good. The only thing that was defective was the clutch arm the pushes the pin, it wore out and I was not able to start my bike.

If you want dependability and reliability, go 4 stroke. Another advantage of the 4 stroke is that you can run it twice as long as a 2 cycle before over heating. My experience with any 2 stroke, they become finicky, going to spend more time trying to get it started.

Good vid,and great tips."G-series"is the cylinder style I tried to describe once.When i'd run through 4-5 tanks if fuel I let mine just rev as far as it wanted,and was afraid after it hit 26mph with a 56 tooth drive.It was still winding up at about 7000rpm or so vs 23mph with other cylinder.The flow of air,and torque were both increased.

Great information I'm looking to get a motor for my mountain bike thanks for the upload

China doll gang wya???

People don't understand how fast these motorized bikes can go

Just to be fair the Anbull 80cc bike motor kit is a good buy though there are better.. (i got it thru amazon with the 4 year warrenty for 20 dollars which for the first time builder I highly suggest.) The hardware was decent but the motor case bolts were cheap but the motor ports are clean and clear. I have got 40 mph as per my weight 175lbs. Thanks for the video. good job.

I wish this video existed 2 months ago when I bought the specific version you said not to buy...

I bought a Motoos 50cc black last year on Amazon, looks like it is even less expensive this year. I don't think it was all that bad although I chuckle when I watch videos that say it takes 3 hours to put one together. It took me 3 hours to clean the paint out of the spark plug hole.

love the vid 👍🏽 subscribed

Yd100 in the house, update you soon

13:05 powder coated motors always "suck" meaning they cause tolerance issues at every mating surface, therefore they create a vac leak..... and therefor the motor literally sucks air in from everywhere. will be running lean until she pops. if you can get her to run at all.

i think bike berry listened to you, i ordered their cheaper mega motors kit and they sent me the bbr one for $10 more without an upcharge...

i have my kit set up but the rear tire is locked even when I compress my clutch can anyone help me out?

Keep on gas and those who don't have license while you can ride one of these and get back-and-forth to work. They like little Mini mopeds when you're done. Plus with the gas hyken, it's better on gas. If you just want to get around in your town.

Thanks for the info and your time...it helps to know if you dont

Any RU-vid channel which specializes in 4 stroke kits?

Thank you for this video. Very informative for newbs. Although I already got my motor a while ago and didn't know anything about it at the time, (and still didnt until i saw this)it's nice to know my motor has all the best bits and for the best price too.

Hear here! Bicycle-Engines Zeda80 is pretty bullet-proof, I've got two, and they both run great! Some of the components with the kit leave a bit to be desired, but both those engines exceeded my expectations, I recommend that outfit to everyone on the Facebook that asks where to buy...

Thanks for the video & letting us know you weren't gonna cover 4 strokes & electrics.

Thank you. Just in time!!

I buy my kits from ebay. I take them apart. Then I put them together right. No break downs then. $120 for a good kit.

If you're going for long Non-Stop rides you need a four-stroke. The two stroke will overheat. Even the yard tools I was two stroke engine chainsaws and all will overheat. You're supposed to put them down and let them cool off every 20 minutes..

One big thing I can tell you is look at any maintenance video on these bikes on youtube! Most older guys dont hand start the threads and they also crank the hell on an electric impact on that shitty low graded steel/ low graded aluminum. They need to be teaching the younger guys proper steps putting it together instead of doing it as fast as possible! Torq wrench, no new person needs to be slamming screws down with an i.pact! I'm trying to get a used one running for a friend right now it's a cheap kit and almost every problem u mentioned in the video hardware wise this has! From previous owners operator errors! Thanks for the video!

Feb 2021 where do we get QUALITY upgrades these days? Heads, pipes, carbs etc. Emphasis on QUALITY. Are we limited to the obvious 3? I don't mind spending more for better parts.

Would you say there's a big jump in performance with a YD100 over an 80cc with the g series cylinder and 40mm stroke? Been researching kits and I'm torn between the two.

I love the information you give on your channel! I am thinking of possibly converting a Huffy 26 speed mountain bike. I might need to pull a fairly heavy trailer with it. I am considering the Wildcat PK 80 or the Zeda 80. Could you tell me what your recommendation would be between those, or if you have another recommendation? This would be my first build and I do need something budget friendly.

What about 4 strokes?

Can you do a video of what you would consider the essential upgrades to buy eg.. Sprocket adaptor, Carb etc..

I bought a 100cc 2 stroke off amazon, everything cost around $180.00 shipping too so far i've mounted everything except the clutch, but I believe I have everything and I am a first time DYI but thankfully youtube vids have helped me through the whole process because that instruction manual is garbage, I hope I can get mine to start and start riding thanks for the tips on the sites!

Keep doing what your doing. Thank you for sticking with it.

Thanks for the info, and I really appreciate your videos. /Per Lidberg Sweden
