I really wouldn't bother. The motor is designed to cant upwards, and the Gen 2 frame will want it to point down. The motor is much narrower, so you will need some funky peddle arms to miss the frame and swing arm, the Gen 4 motor has a large chainwheel and aligning that given the width of the motor won't be fun, and above all, it would look funny :ROFLMAO: I have plonked one in an upside down frame for you, see pics.

ive heard it is narrow but not 100% sure how much. its the extra battery im thinking off and the lack of resistance when you get to that magic 16mph.

i take it the motor there is gen 4. dose look like it could fit some way. depend on the frame i guess.

They use completely different mounting systems etc - you would have to do some serious fabrication to get it to work, and even then it might not put to tolerances etc.
