Durable Replacement Cranks for a Wide Range of E-Bike Motors

Praxis Alloy E-Bike Cranks are cold-forged aluminium replacement crank arms for a range of compatible e-bike motor systems. Supplied as a left and right arm set, they offer a strong, dependable replacement option for bikes using compatible ISIS spline motor spindles.

The ISIS spline interface is optimised for Bosch and Yamaha motors, and can also be used with compatible Brose, Fazua R50 and TQ systems. Praxis also offers dedicated crank options for Specialized Turbo ISIS and M30/SL motor spindles.

An 8 mm aluminium main crank bolt with a self-extracting design makes removal easier during servicing. Installation torque is 50 Nm.

Important Compatibility Information

These cranks do not fit Bosch Micro-ISIS or square taper motor spindles. Always check your existing crank and motor spindle before ordering.

For Specialized e-bikes, standard Levo, Kenevo, Como and Vado models use an ISIS spindle. Levo SL, Kenevo SL, Turbo Creo and Vado SL models use the M30/SL spindle system and require Praxis M30/SL eCrank armsets.

For full compatibility and identification information, see the Praxis Alloy E-Cranks guide.
