Bafang BBSHD 48V 1000W Mid-Drive Kit vs Varstrom TSDZ-2B Mid-Drive Motor

The Bafang BBSHD is the stronger kit: 1000W and 160 N·m of torque against 500W and 80 N·m, with a 30A controller and a color TFT display. It is heavier and bulkier, and its power is more than many riders need or many frames handle cleanly. The Varstrom TSDZ2B is lighter, fits 68-73mm bottom brackets, and its torque-sensing pedal assist feels more like a normal bike. Buy the Bafang for climbing, cargo and heavy riders; buy the Varstrom for a lighter, more natural ride on a standard frame.

• Choose the Bafang BBSHD if you want maximum power and torque for hills, cargo or a heavy rider, and your frame has a 68mm bottom bracket.
• Choose the Varstrom TSDZ2B if you want lighter weight, torque-sensing pedal assist and a fit across 68-73mm bottom brackets.
