Home built motorized bicycle

Leave me a comment if you want more information. This was a Huffy 26" girls bike and I added a 4 stroke Tecumseh 49cc, 3 hp engine to it. The frame has been stretched 28" and lowered. It has full electrical features, headlight, high beam, turn signals, post lighting, horn, brake light plus centrifugal clutch, gearshift style drive engagement, storage, purple cruiser lights, foot rests, springer front fork and chrome fenders. It has a 12 volt holding relay for the kill switch and a 12 volt flasher for the turn signals all feeding from its on-board 12 volt motorcycle battery. Top speed on the flat according to its Stewart Warner speedometer is about 40 mph plus it is a great hill climber. The bike weighs around 100 pounds and can handle a rider of up to 300 pounds. See lots of construction details in my other video. Thanks.

did you go through the process to make it streat legal? With the DMV?

@longjonsilvrr Thanks for the question. The answer is no. I pretty much lost interest as I have no convenient storage or places to ride so the bike now is just sitting out in the shed and never gets ridden or even started for that matter. It's a shame but I can't bring myself to get rid of her. I have so much of myself into it. So there she sits collecting dust.

Yup, the kill switch is also shown in my wiring diagram. Just go take a look at that video and it will show how that works. The diagram shows every wire in the bike and what each wire does.

Thanks for the question. I posted a video that shows my wiring diagram here youtube.com/watch?v=rli5dEzPZV­o You can stop the video and blow it up to 'full screen' and then do a screen print and you have the diagram. It is pretty simple, just a 12 volt car flasher and my diagram shows how to wire it. Good luck. Let me know how you do.

this is truly amazing, kudos to you! one thing i was wondering, what is the gear sfift from? how do you have an effective clutch? thanks!

[dickandchristina]

@MrMechanixman Hi, Thanks for the kind words. The gearshift lever is made from a piece of mild steel dowel stock with a Ford truck rubber handle I found at the auto parts store. The other end is welded to a turnbuckle that tightens a belt connecting the engine clutch to the rear wheel jackshaft through an moveable idler pulley. The clutch is out of a box made for go carts and it works pretty good. There is also a mechanical interlock.

That is one slick retro looking bike. Good job at making it look like it came straight outta the 50's/60's. Not many enthusiasts can make it custom like that. Even if it is collecting dust, hang onto it!
