Changing the chainring on an older Bosch e-bike means getting the lockring off first. The IceToolz M801 is the right fit for Bosch's second-generation motors, made from wear-resistant Cr-Mo steel.

Highlights

  • For Bosch Gen 2 Active Line, Performance Line and Performance Line CX
  • Covers Bosch motors up to 2019
  • 1/2-inch square drive
  • Cr-Mo steel, 158g

Workshop-grade fit

Drive the M801 with a 1/2-inch two-way ratchet such as IceToolz's 53R4. The ratchet lets you work quickly in tight spaces around the motor, and the Cr-Mo body is rigid enough to break a firmly tightened lockring loose without spreading.

Compatibility & fit

IceToolz lists the M801 for Bosch Gen 2 Active Line, Performance Line and Performance Line CX drive units, up to 2019. Newer Bosch Gen 3 and Gen 4 motors use a different tool, IceToolz M803. Check your drive unit generation before ordering.

Our workshop services Bosch e-bikes and can change the chainring for you.

IceToolz covers its products with a two-year limited warranty from the date of purchase against material or manufacturing defects under normal use. Damage from improper use, accidents, abuse or modification isn't covered, and proof of purchase is required. For warranty support, return the product to Tune Cycles and we'll manage the claim with KWT Imports, IceToolz's Australian distributor.
