Thanks your bike looks great . i have a medium frame 17 inch . I havent got the conversion kit yet , i think i will need to mount the battery like you have . what motor and battery did you use . thanksI did my Zobop about 18 mths ago and it has been great. Depending what size frame battery you have (mine is a medium) you may have to mount the battery under the down tube, there is a theoretical clash of wheel and battery dependant on fork pressure but in 1000 miles of on and off road there have been no problems. Having said all that, as a precaution I've recently limited the max fork travel.
Thanks will start on the conversion in the new year is there any difficulty or mods to do to fit the motor to the bottom bracketIt's a Bafang 250w with a 17Ahr battery and a 42t Precialps chainring, it helps with gearing and chain alignment. I have thought of a triangle battery but so far the underslung mount has been fine.
Range wise it varies a lot depending on terrain but 60-70 miles is very very easy with mixed riding and I think for on road only 80 plus is achievable. The battery has never run out on a ride.
For winter I made a cover/shield from some rain gutter offcuts (heated, flattened, then shaped) that goes under the battery and motor to reduce water and mud collection as the gap between battery and motor is a perfect mud trap.
The bike is used on road, bridleways and gravel tracks etc so fitted some 50/50 tyres, 2" Schwalbe Landcruiser.
Over the 18mths, I've also added a gear shift sensor to help smooth the shifts, living in Wales it is rarely flat so end up changing gears quite a bit, and just recently a hydraulic brake sensor. The brake sensor was mainly to momentarily cut power on slow tricky maneuverers.
That looks very interesting, I see you have reversed the shock...neat. I almost bought a large size but was concerned about the stand over height. Have you a better photo showing the battery in the frame please?
The only potential issue is the 73mm width of the bottom bracket, the second locknut only just engages so it needed loctite. I'm not sure if this is good practice being newish to this, but I also put some blue loctite (semi permanent) inside the bottom bracket to take up the small amount of slack in there. I also have a lump of metal epoxy between the frame and motor as support.Thanks will start on the conversion in the new year is there any difficulty or mods to do to fit the motor to the bottom bracket
