L-R Swingarm Big Block Drive for Qulbix 76R and 140R


Product Description

This Big Block Drive was designed to fit the swingarm of the Qulbix 76R, 140R and the Mario Bike and Risun Qulbix clones. With 8000 watts of power and half the weight of comparable hub motors, this drive is a substantial performance and handling upgrade for these bikes. It was designed for left side drive, which leaves the right side of the bike for dedicated pedal gearing. It can be run with a freehub with a disc brake flange sprocket adapter or our aluminum billet hub that has left side flanges for both a disc brake rotor and our 96 tooth stainless steel wheel sprocket. Reduction with our 12t #219 motor sprocket and 96t wheel sprocket is 8:1 in one stage.
