Premium quality crank arms designed and cnc'd in house to replace all the crappy stock crank arms most ebike kits come with.  At 170mm length with a taper in one crank arm, this allows it to fit all sizes of BB's for drives and is a one-size fits all solution for a simple upgrade that will make your ebike look that much better.  Equipped with self-extracting bolts, these crank arms can be readjusted on re-tightened on the road without the need of a crank puller.
