Has anyone bought longer cranks for an E bike, such as 172.5 or 175 mm, or do they even make them for a Bafang mid drive? I am 6 ft 1 '' an longer legs, so normally use 175mm cranks on a road bike. For a mtn bike or hybrid bike conversion, using a bafang mid drive, 170mm cranks seem to short. Yes clearance and corning need to be considered. Wondering why 170 mm seems to be the standard even for tall riders.
