46 Tooth Drive Line Crank set specially made for our City Track Pro E-bikes, it is high quality ISIS drive,and what makes this crank set special is the fact that the crank arms are at 140mm in length as opposed to standard 170mm, The reason for this is because our         E-bike has 24″ wheels and if used with 170mm crank arms the pedals will scrape the ground on tight turns.

People often ask if it is harder to pedal with that shorter length, in fact the difference is barely noticeable if at all, and there is the added bonus that the pedaling is actually easier on the riders knees.
