Hello E-Wheels. I converted a Specialized Pro to an ebike. I used a BBS01 250w mid mount with a 36 volt 19.2 ah battery system. I ride with a local bug and am regularly cycling up to 120k per ride. I have been keeping careful stats on my charging/distance and consistently achieve in access of 170k. I ride the bike, in the sense that I use the gears and where possible switch the motor off. My riding is mainly done using Assist level 1 or 2 - mainly 1.
