Okay, it would seem 20t is the largest size they make. Has anyone ridden one of these Bosch mid drive bikes? Does that crank gearing cause much drag? I just read the other thread about the newer version that claims less drag and a normal chainring.
The Trek ones were totally sold out when I checked recently, so not much chance to test ride one. I could order one locally though if they become available.
