Bottom Bracket Fit

The ToSeven DM01-750 is a 750W bottom-bracket mid-drive motor with an integrated torque sensor, rated for 48V-60V systems and producing up to 160Nm of output torque (40.27:1 reduction, 160 RPM max). This is the 68-73mm BB bottom-bracket fitment, shipping with a 46T chainring (38T-54T compatible) and IP65 weather sealing. ToSeven uses a proprietary closed communication protocol, so the motor only works with ToSeven's own bundled display and brake accessories.

In brief: 750W mid-drive motor. Fits 68–73mm bottom bracket. 48–60V rated. From $390.
