    stage 2 better tires brakes and mod FD to use SAE parts not metric
    had to turn spacer between motor and friction drive down in the lathe

    stage 3... make a new mounting system to allow use of a quick release rear wheel

    only a handdrill, dremel with cutting wheels and a hand file were used to make the slots... so much for me being a doofus

    What are those 4 bolts protruding from the u-channel in pic 3 for? Also the roller is crooked in relation to the tire. You need that perfectly straight in relation to the tire. OK done with your on the Nice setup, is that 1 of those 40$ amazon 43cc 2 stroke motors? How does it perform?

    the 4 bolts are for this basket that I can't use now now
    working on getting a pannier and make a mount for it to replace basket
    the 43cc 2 smoke needs a much better carb as it is a PITA to start

    That's a cool way to motorize a rear suspension bike.
