Rebel against scuffing

The wider frame width needed to accommodate electric motors and the narrow stance needed for pedal ergonomics means shoe rub is increasingly prevalent on eMTBs. Era’s unique stainless steel wear plate protects against this damage. Keep your cranks looking fresh after spinning up all those pedal-assisted climbs, all while adding additional impact protection.

Lifetime Warranty. Crashes Included.

We made this carbon e-bike crank so strong, so stiff and so durable we are backing it up with a Lifetime Warranty inclusive of crashes. Let ‘er rip. Our cranks can take it.

Resonate with your ride

The Era eMTB crankset saves grams while staying scuff-free and looking great. It’s also available in a shorter 160mm length to avoid those pesky pedal strikes. Optimized for ISIS (e.g. Bosch Gen 5 CX, TQ HPR50) and ETOR (e.g. Fazua Ride 60) spline standards. Cruise up for another lap and let your cranks do the talking.

Stiff and light!

Had these on my pedal bike and loved them so had to add them to the eBike too! Saved me 1/2 pound over the crappy aluminum ones that came on the bike

Frequently asked questions

Which motor interface standards are supported?

The Era eMTB crankarms are designed for compatibility with major e-bike motor systems, categorized by the following interface standards:

  • ISIS: Compatible with various ISIS drive units, including the Bosch Gen 5 CX, TQ HPR50, and Bosch SX.
  • ETOR: Specifically engineered for ETOR spline systems, such as the Fazua Ride 60.

Please ensure you select the interface option that matches your specific motor drive unit. These crankarms are available in lengths of 160mm, 165mm, and 170mm to suit your riding setup.

Does the carbon construction handle high-torque e-bike motors?

Yes. These cranks are specifically engineered for the high-torque demands of full-power e-bike systems. Despite their lightweight carbon design, they are built with a robust UD carbon fiber construction and reinforced metallic inserts at the spindle and pedal interfaces to ensure they withstand the intense power and stress generated by e-MTB motors.

Does the 160mm length help prevent pedal strikes?

Yes, the 160mm length is specifically designed to reduce pedal strikes. By choosing this shorter crank length, you gain extra clearance from the ground, which is particularly beneficial when navigating technical terrain, allowing you to ride with more confidence and less worry about clipping your pedals.

Are these crankarms compatible with Fazua Ride 60 systems?

Yes, these crankarms are specifically optimized for various spline standards. The Era eMTB crankset is compatible with:

  • ISIS spline standards (e.g., Bosch Gen 5 CX, TQ HPR50)
  • ETOR spline standards (e.g., Fazua Ride 60)

This versatility makes them an excellent choice for riders looking to upgrade their specific e-bike motor configuration with a high-performance, lightweight component.

Are these carbon crankarms easy to install safely?

The Era eMTB crankarms are designed for straightforward integration with your e-bike’s motor. They arrive with the necessary pedal washers and crank boots included to ensure proper assembly and immediate protection for your investment. Because these are engineered for specific motor interfaces like ISIS or ETOR, they provide a precision fit, but we always recommend ensuring you have selected the specific variant that matches your bike’s motor standard during checkout.

Do these crankarms offer a balance of stiffness and flex?

Yes, they are engineered to provide a balanced ride quality. They offer enough stiffness for efficient power transfer on climbs and aggressive sections, while maintaining a natural feel that doesn’t sacrifice comfort during long days in the saddle.

Lifetime Warranty, Crashes Included.

Crashes are part of mountain biking. When they happen, we have your back.
