I just wanted to share my build hoping that it will help someone else who might be wondering if it will fit their Scott Genius. It's a BBSHD 100MM, I had to grind 1/8 inch off the right side of bottom bracket but now the motor is centered with even spacing of the cranks. The battery is a 48v 10ah mini shark. I would like a larger battery but that's the only one I could fit in frame. Also The way I mounted it, I can't take it back out without unbolting it from the frame. So far I love it!
