The Praxis eCranks (EC-2 Type 2) are premium performance upgrades designed specifically for e-bike enthusiasts using Bosch Gen5 CX, PX, or Avinox drive systems with an ISIS spindle interface. Engineered for both durability and efficiency, these cranks offer a significant upgrade for mountain bikers and urban trekkers seeking better pedal clearance and long-term reliability. While these cranks provide an exceptional strength-to-weight ratio, users must ensure they are using the correct motor interface as they are not compatible with non-ISIS or non-specified motor spindle standards.

No, these specific EC-2 Type 2 cranks are engineered for Bosch Gen5 CX, PX, and Avinox motors.
You need an 8mm Allen wrench and a torque wrench capable of hitting 50Nm.
The set weighs approximately 534g.
No, these cranks are designed exclusively for ISIS spindle interfaces.
Follow the manufacturer's torque specifications and ensure the splines are greased; typically, grease is sufficient, and thread locker is not required unless specified by the motor manufacturer.
Verify the bolt was torqued to the specified 50Nm and ensure the splines were fully seated before tightening.
The included M24 bolt has a self-extractor; ensure you are unscrewing the outer bolt head counter-clockwise, which will push the crank arm off the spindle.
Installation of the Praxis eCranks requires basic mechanical knowledge and specific tools to ensure safety. You will need a standard 8mm Allen wrench for the M24 main bolt. Always apply a thin layer of high-quality bike grease to the ISIS spindle splines before installation to prevent seizing.
Crucially, the crank arm bolts must be torqued to exactly 50Nm. Using a torque wrench is mandatory to prevent damage to the spindle or the crank arms. Regular care involves checking the bolt torque after the first few rides and periodically cleaning the crank-to-spindle interface to remove grit and debris.
