hey i was wondering if it would be easier to put a motor kit on a cruiser or a mountain bike? If mountain bike, what size of frame is best?

Mt Bikes are easiest, frame size is just what fits you

Most 24" or 26" bicycle with diamond frame and horizontal top tube should have sufficient space to mount motor.

At least 12.5 inches running along the seat tube from the top of the bottom bracket to the bottom of the top tube.Tubing size from 1-1.5inches on the both the seat and down tube. Plus or minus 70deg. above the bottom bracket between the down tube and the seat tube. Inner distance between pedals needs to be greater than 4.5 inches in width to clear the 4.5inch wide motor.

What kind of bike would you recommend?

I chose a 26" single speed cruiser for these reasons: large tubing, strong frame, style and smooth ride. Before motorizing it I replaced the front forks with a set that had front brakes and suspension forks. I also installed a lay back seat post and a large seat with coil springs. I suppose a mountain bike already has some of this, I just did not have one at the time.
