hi guys,
here is something im working on.
this bike was once an electric and the battery gave out and i didnt wanna drop another $300+ on another battery, so its getting a gas engine on it.
this is what it looked like before:
it had a 350w brushed motor on 37v li-ion battery. top speed was around 30mph until the batteries went on it...lol
here is what im working with now:
here is a close up of the motor and driveline
its a homelite bandit 25cc motor thats been retimed to run in reverse which is powering a shimano 333 hub thats set up for neutral-1st gear-2nd gear. i have a 10 tooth sprocket on the motor and 18 tooth on the hub so it equates out to the "spindle" being a little bigger than 1 inch. the whole mount is made out of 3/4 inch square tubing. i had it out today and im having issues with tuning it. but it does work. its still a work in progress since its my winter project.
here is the first start up of it
i know LeeK did something like this with a 3-speed hub and a 4-stroke Robin-Subaru engine. i wanted to give it a shot and put a unique spin on it.
