An evolution of the original design, these eCranks now exceed the ISO Race standard for enhanced performance.
Featuring a low profile crank arm, they effectively reduce pedal strike during technical climbs, allowing you to tackle more challenging trail sections and return for another lap with less effort.
With a Q Factor of 182mm when installed on Shimano EP8 systems, these cranks are designed for optimal compatibility and comfort.
Weighing in at just 440g, they strike a perfect balance between durability and lightweight performance.
For best results, have your cranks installed by an experienced eBike mechanic. Ensure M6X1.0 bolts are tightened to 14N-m, and apply Blue Loctite to each bolt and end cap. It’s important to check the bolts after your first ride to confirm they are at the correct specifications.
