Hi I've spent a nice hot day converting my new 29er to mid drive.. After stripping everything from my lovely old 26" Carrera Kraken..I've got to admit I've been well impressed with my bbs01b setup and on the the old bike it worked really well. But it was only gona be a short lived thing before I wanted a newer ride.swapping the bits wasn't to much trouble until I got to the bottom bracket the motor would not fit through the hole so out came the Dremel ..well after about half an hour it was going through..I've taken some metal from the drive side of the bottom bracket so the motor fits tighter to the frame..seems to have worked well..done away with the shifter and derailier. Got to try and save some weight..been out for a quick ride tonight and all seems well . I have not fitted the gear shift sensor this time and have found that I need to remember to flick that brake lever before changing..but I think in time I will either like it or put the sensor back on..As for settings I haven't touched anything it still thinks it's a 26" at the moment..
