My stretch 212cc build

[Scorpion1]

I already have an 80cc bike and thought i'd build a bigger one. I love it, 212cc, 47 mph, straight pipe and 4" wide tires on a Micargi Seattle frame.

Amazing! Hows the acceleration, what gear ratio?

Thanks! Acceleration is mid-range. Not hugely fast but not a complete slug either. 10 tooth on motor and 80 tooth on wheel.

Hi Scorpion 1. Good looking build and good performance numbers. Could you please briefly explain and or show two or three pictures of engine mounting and how you routed the drive chain to achieve alignment?
Thank you.

Picture of mount. I had to route the frame thru one of the rear frame tubes. I re-supported it with square aluminum stock. It works just fine and has not had one issue with alot of miles on it. Some folks said its unsafe and will fail blah blah etc............ zero issues with it

I know this post is over 4 years old and I don't know if you still have the bike, but I was wondering what your using for the electrical system, particularly the device that's above the battery
