Seems like the Commuter C and Commuter S have both gone on sale for the same price.
The only difference between the 2 models is the frame. The components are identical. Here are some specs:
27.5" / 26" Wheels
Bafang Mid Drive M420 (250w | 80 Nm of torque)
Samsung 36v 14Ah (Range: 40-95km)
Upgrade: Samsung 36v 17.5Ah (Range: 60-110km)
Enviolo City Internal Hub (Stepless)
Tektro T285 hydraulic discs
