I am building an electric quadracycle with something called a Rhoades Car. (It's parbikes now). This cycle has a dual derailler system, and the drive sprocket is located on the left instead of a normal bicycle's sprocket on the right. My question is, can the Bafang BBS02 be reversed in its rotation? If not, I must redesign the drive/chain system. And, will this affect reliability due to the rotation change?
