This is the first and worst build I did. Mainly because it was made it China.

This is the second build I did. It is a Staton Gearbox connected to Sick Bike Parts Freewheel Cranks

This is my third build. It is a Thats Dax Friction Drive connected to a Harbor Freight 52cc Waterpump Engine.

This is my Fourth Build. It is a DIY Scooterguy mount with a Honda GX35 engine.

This is my fifth build. It is a GEBE kit with 105G wheel and a Tanaka PF4000

I got out of motorized bicycles and then got a Honda Ruckus

I couldn't keep up with traffic with the Honda Ruckus so I got a Yamaha Zuma 125 which I still have

Now I don't feel as safe on the Yamaha Zuma 125 as I did when I was on a motorized bicycle on the sidewalks. So I'm building my dream bike. An Electra Townie 21D with a GEBE kit velocity 105g wheel and a Robin Subaru EH035 engine. Hope you can learn from my experiences.

Nice post!

Based on your experience, what is the benefit of having the engine mounted over the back wheel instead of in the frame?

A 66cc engine with a dirt bike pipe should yield ~3hp

Get your cheap ass to buy a a decent $500-1k bike & you should have no trouble keeping up with traffic

A 66cc engine is made in china and is inferior to a japanese engine. I own a Yamaha Zuma 125 and I keep up with traffic just fine. I like the sidewalks better at a slow speed. I feel safer there than on the road with cars.

I always wondered how difficult it is to get the weight of the engine balanced when it's on the back. How is it riding with more weight on one side of the bike than the other? Does it affect your turns or do you not really notice it?

I don't notice any balance issues. It is only about 10lbs on the rear wheel with the GEBE system. I'm more concerned with reliability than asthetics. I will admit when I came to this forum I liked the 66/80 cc china kits better because they looked cooler than a weedwacker engine poised over the rear wheel. But after pulling my hair out with chineese junk, I much perfer the reliablity of a japeneese engine.

Ha! That's understandable.

Your post made me think of myself......As I have a GX-31 powered abomination I built that drives the front cranks through a gear reduction box and does about 50 m.p.h. on flat land..............(6 speed cartridge on the rear)
I got tired of crashing on it, as mountain bike brakes don't work well at 50.
So I went electric.........As I too prefer the sidewalks for short commutes. I have a couple of electrics now........All home built.
But I currently have been digging the heck out of a little Schwinn scooter that I've modded the heck out of.
Just a shear kick in the butt.........20 minutes on it can restore my youth, and I'm over 50.
That's where my evolution has taken me so far.
I would've posted some pics, but was somewhat challenged w/ the procedure........Perhaps not being a member.
I did very much enjoy your post.

P.S............I'm 6'-6" and ride the scooter standing up, which makes me about 7' coming through the crowd at events.
The line of sight in a crowd or on the sidewalk is incredibly enjoyable.
