Honda Cub engined motorized BMX bike
 

This style bike is wild looking. I like it. Seems like it would be a lot of fun to ride. The minimalist styling and possibility of making it streetlegal is very appealing. These could become very popular in the future. The limited fuel capacity looks to be the only downside to this design. They are made with recycled Honda Cub forks, swing arms, wheels and brakes. Simple to duplicate.

If I was going to build one, I would make it a little differently using mountain bike parts and 18” motorcycle wheels and tires.

Another big downside is the lack of rear suspension.

Looks like a very difficult build, but much cheaper than buying a motoped.

The Cleveland CycleWorks guys already have it all worked out.

Good point. I like the FXR a lot. But the price is $2495. I’ve been to Cleveland CycleWerks and checked them out. Nice bikes. The owner Scott is a nice guy too.

I built a motorized biycle once thinking it would be fun. Used a steel framed Schwinn cruiser bike and a honda generator motor on a friction drive with heavy duty rims, upgraded brakes, etc. It WAS fun to build but an absolute pain in the butt to ride, literally. Even with the springer fork. That underbraked BMX frame looks worse, and dangerous. I sold it for what I put into it.

If you want a small cheap motorcycle, there are a lot of CT70 clones out there, some of those get very cheap, or just find a CT70 frame needing a donor motor and put in an inexpensive Lifan.

I rode a motorized bike for 5 years. It was smooth at 25mph. I added a heavy front wheel from an industrial trike that seemed to make the bike settle down nicely at cruising speed.
-There is no way I would want to do 45 mph on a motorized bicycle on the street. You are much more comfortable at that speed on something heavier.

This motorcycle does not use a BMX bicycle frame. It’s just made to look like a BMX frame. They use custom made frames with thick wall tubing, probably chromoly. That’s what I would use. It does use repurposed Honda Super Cub parts. I would imagine the steering head to make it street legal. The thought was to bring life back to the old Super Cubs with something easy to build. Adding a rear suspension would Not be difficult to do.

I’m not saying that I want to build one. I have way too many projects now. I just thought it was cool. I’d go with a kickstart, semi-auto engine to eliminate the electrical system and foot operated rear brake.
