Motorized Schwinn Stingray 

Was gonna sleep, currently 4:50am, but motorized stingray more important

I am 67 and in Jr High we used to call these Greasemobiles as the Greasers from the poor side of town were the first to build them. Back then we would remove the seat tube and use a bumper jack to spread the upper and lower tubes to make room for a Briggs and Stratton 3.5hp engine. We would then take the same bumper jack and spread the rear triangle (side to side) to accommodate a wider rear mini-bike tire while still retaining the 20" bicycle tire. Me and a friend took and Schwinn Orange Krate with the springer front end 16" tire and front drum brake and mounted a highly modified MC101 with an expansion chamber and two carbs and reed valves. It was so powerful you could take it up to 60 and open it up and it would wheelie......a wonder we lived through those days ;-)

That looked fun LA, Thanks, waitin for the next vid., Cheers!

A full suspension frame build would be real cool to see! (not because i just bought a downhill bike and need to see the process of motorizing it or anything, it has nothing to do with that)

I love builds like these, where it's at the edge of everything.

Glad I stayed up 2:30 am in california cheers!!

I made one of these too and I used a ''women'' frame because it was too tight with my old stingray but I added a tube under the seat to fix the gas tank. It wasnt all that odd looking but now that I see yours I should've give myself the headaches of using a regular frame the results looks much better

I rushed to watch this video as soon as it came up good job

Great video, thanks 👍

Sweet lil ride man .

I did a build very similar to this. It was a CCM Cougar. I rode it for a week, and had the hardest wipeout ive ever had. Got rid of that build fast. Damn that wheelbase.

Very Cool

Holy cow man, I was thinking about doing that myself but I didn't think it was possible with the crosstubes. I'll have to look again, but I think the one I was looking at has a 16" front wheel and a spring on the front forks and a 20" back "Slick". I haven't done many builds but I really want to try this one. Watching this is going to be a giant help. I wonder if I could somehow mount a disc in the front.

loved my stingray , used my paper route money to buy it, it was 57$ at the Firestone store @ 1967 I wonder how Schwinn quality is these days compared to back then…They were really good for wheelies nearly a unicycle lol…I enjoyed the video, and now at 240 lbs and 6 4” probably not very realistic. cheers..

Thanks

Nice LA, nice!

You’re so awesome dude!

Exactly what a "Stingray " needs. Has the cool factor that doesn't look forced.

I was about to pick up a vintage Huffy version of the Sting Ray for 50 bucks. It was rough but some TLC and elbow grease got it on the road. Then I put a 750W hub motor on the front. It's fun as hell know.

Isn't that seeutek a bit like the 400 year old hammer by now? New head, new handle, same hammer 😉

Bro this bike is wicked i want one now

the only bad thing I see is that dangling muffler - I think I would just straight pipe it if there were no shorter and swept under mufflers to put on it * I recently got a 2022 Orange Krate bike, they still make them!

Awesome needs some twisted handlebars and forks

welp, you have yourself a little guest rider build now. probably going to make one as well though probably going to change the pipe to my flex pipe and redo the paint job to a crimson red. also name this build the flying flea.

Turned out good .lol !!

First let me say I in general and all around just love the big cause of what it is and how it looks and personally I feel the chosen color you got is the epitome of what I picture in my head when I think of one of these vintage bikes so kudos for that choice. Second I have to 100% agree as much as I think the pk80 is a very well made and put together motor out of the box I feel that the seeutek is by far one of if not the most reliable motor out of all the motors I've used to date they're just simple and they just work every time. And third I think it's just a great build all in all between the look The styling just basically everything that that bicycle has to offer as a bicycle makes it an incredible looking I am assuming feeling motorized bicycle. Great looking just a real fun build all the way around. Good job brother!

the high handlebar/stem position will make any bike a comfortable joy to ride. i bought 'touring quill stem' on my commuter bicycle 3 years ago, never looked back. this thing is two feel long and with the widest seat i could find its amazing. I only mounted an engine on this trusty commuter two weeks ago, needless to say i am already addicted to it, going on joyrides daily after work. Its my first time having freedom to travel around, I never owned any motorized vehicle before.

You need to incorporate the perpetuum mobile principle for free energy on your bike.

I had the same issue with mine, so I took a torch to the offending pedal shaft, bent it out a tad, re-tempered with water, and it's been fine ever since...

Hahaha, just needs doordash saddle bags

If you ever have issues with the motor mounts are crooked try adding some washers underneath the back mount. I learned this trick when I had issues with the felt faker frame chain ring hitting the bottom of the motor adding washers will space out the mounts

That's not "micro", that's a regulary sized bike, i bet she has a great personality too!

If only Schwinn would build a 26 inch or plus version as an E-bike or one that could be converted.

schwinn please make a 24 or 26 version

Now that's cool

Glad my solution could be of help! Another cool thing you can do with intake extension is, if you make the metal pipe that attaches to the carb long enough you can actually slide the carb in and out of the heater hose and tune the intake length

That banana bar was never made to support a full grown man, I can't tell you how many kids I saw skewer their leg when it broke.

Hell yeah bro awesome build I have the older one there super comfortable to ride

looks great bro glad i told u about it. keep on building bro! thanks for the shout out. i was actually looking for a cranbrook lol

It would be nice if there was an adapter/ spacer to bring out the 10 tooth sprocket out so the chain won't rub on the rear tire.... Another thing is a sprocket cover with spacers to work with the new position of the sprocket

there is a 24" replica version of this bike out there somewhere. I've been looking for one at a reasonable price for a long time now.

Nice build yeah I'm going to throw a pair of handlebars like that on my Schwinn legacy

I really wanna try this!!

awuah it's such a cutie!

Some guy from a circus with some monkies called and he wants you to call him back .

That is cute as can be🍻

I had no idea motorized bicycles turn heads this much... every single dude does a double take after he sees a pedalling with braap, not sure if they are laughing at me or with me though :D

Gangstah.

Please tell me how you get the engine to idle and what kind of fuel oil mix you use.

XMX rim will fit the one with the pedal brake with the sproket plate adaptor ,came to that idea after weeks of work ,and olso de chain tentioner with the curved adaptor

Kenda Kontact 20 by 1.95 is a good tire for just that. I have the 26 in version on my phantom 85 bike. The 26 inch is called Kenda Komfort. Tree fort bikes should have them, I have done a lot of business with them and always been highly satisfied with their company. Plus free shipping.

👍🔧🔧🛠🚲

As awesome as gas is, this seems like it might be better suited as an electric bike

😃👍

I would love to buy one of those bikes for a project. But first do you think a yd 100 or a phantom 85 would fit in the frame. I'm a bigger guy so I need the power lol

Nice build hover! I finished my spare parts AF80 build on a 80s noname 26 inch mountain bike. That makes it my third build after the Screamin Demon (Zeda triple 40) and Catalina Superior (Phantom 85) I need a suspension fork though. Always something

My next build will definitely be something like this !

That's awesome! We got the stingray! Also you should mix up gas with castor oil, smells so good!

5am upload

How do you spell the name of that little 49cc engine? You have any other recommendations for 49 cc motors?

Another great video. Your build looks like an old 70 's mini bike more than a bicycle. I think it's because the engine looks bigger in the frame vs. A full size adult frame. It looks like a lot of fun to ride and probably is because it weighs next to nothing.

funny bike

Hermosura de bicimoto es como para tenerlo colgado.

Nice! I found this video to be a pleasant surprise. Put the original grip on the throttle. Symmetry looks better imo.

And still not available in Canada...

This build would be perfect for my short wife. Been looking forever for a frame that would fit her and a motor

I want to put a motor on a bmx cruiser, like a 26"

So cool! it definitely looks like a chill ride. Decent price is always a plus too. It would be cool to swap out the back hub to a machined 4 bearing beefy sucker for reliability And Looks.

All the places could’ve parked for intro u choose dirty ass puddle in background of beautiful bike lol

Have you ever thought about building a West Coast Chopper motorized bike

Parabéns pelo vídeo faz um vídeo colocando polia e correia dentada

Cool!!! Looks really fun to cruise with it and just enjoy the views 👍!

I'd love to build one....wonder if the 100cc...non YD or BT the one that looks like an 80cc would fit that frame

That's pretty sweet ! Any chance you know of anyone putting a chain ring on a 3 speed sturmey archer hub? I am trying to figure it out🤪

Anybody know good vendors for engine's only? I'm trying to find a Zeda triple 40.

Seutek was my second build. I never used the kph gauge it came with

I bought one too and I'm concerned about just having the coster break. Is there any kind of C breaks for the front

Hey brother , curious whats your most recommended bike frames to use for motorbike?

So frickin cool! I'm still shaking off last night's crash and now you've already got me thinking about my next build 🤕🤣🥴🤪

Great build love the color. I would highly recommend changing the exhaust. The stock ones hang to lowe.

also thx for your detailed guide videos, helped a lot, the building was a comfortable experience thx to you

😛

Nice compact build! That banana seat is begging for a wheelie. Are you ready for another wheelie? 😁

I have a gt7 engine kit from kingsmotorbikes and the carburetor is junk i was wonderingwhat is a decent carburetor that you could recommend

never been this early

This is as tight of a squeeze as my 4 stroke engine and my Huffy Lockland frame 😌

Nice video!! I would love to see a video of you taking this bike on a long trip! By the way i'm currently building a motorized BMX bike though the engine is a rear axle mounted one. Will share it at your Discord server once its finished. Ride safe always!

Hey Bud! Curious, what jet size did you use on the carb? Is that a 66/80cc motor? Thanks

i wouldn't put an engine on a bike smaller than a 24"

The Original Stingrays didn't have a front fender, all the "Crate" bikes did have a smallish, basically useless front fender...

Too bad these bikes are like $699 these days

Electric the only way to fly

Looked so impractical but, I can see how that could be rather comfortable cruising low speeds with added padding to the seat.

First!

You're too big for that bike

i bilt one in green made wheelie bars cant keep the frountend down
