The kit I bought was very straight forward. One removes the crank and replaces it with the kit parts/motor. I opted for the shift sensor and the brake handles with sensor so the motor disengages. It is a hoot peddling up a mountain road at 15 mph. I found the conversion fairly easy if you are not in a hurry and don't have a few beers under the belt. The hardest part was getting the grips off!
