The Praxis eCranks (EC-5 Type 5) are premium, high-performance cranksets engineered specifically for e-bikes equipped with the TQ-HPR40 motor system. Designed for cyclists seeking precision and durability, these alloy cranks provide a stiff, reliable power transfer, though they are exclusively compatible with the TQ-HPR40 system and require specific Praxis mounting components for road and gravel applications.

No, these cranks are specifically engineered for the TQ-HPR40 motor system only.
You will need standard crank installation tools suitable for 3-bolt direct mount interfaces and a torque wrench.
These cranks are primarily designed for road and gravel applications on TQ-equipped bikes. Always refer to your bike manufacturer's specifications.
The kit includes the crank arms and spindle; chainrings are typically purchased separately as part of the LT2 or DM1X kits.
Keep the connection points clean and lightly coated with high-quality bicycle grease during annual maintenance.
Remove the cranks, clean the spindle and interface surfaces, apply fresh bicycle grease, and reinstall to the recommended torque.
Verify you are using the correct Praxis kit (LT2 for 2X or DM1X for 1X) as the chainline varies between these two configurations.
Installation of the Praxis eCranks requires basic mechanical knowledge of e-bike crank extraction and installation. Ensure the TQ-HPR40 motor is clean before installation to prevent creaking. Use the appropriate Praxis LT2 kits for 2X setups or DM1X road rings for 1X setups to maintain correct chainline specs. Regularly check the crank bolts for proper torque as specified by your frame or motor manufacturer guidelines. Keep the interface between the crank and the spindle clean and lightly greased to prevent corrosion.
