Precision Sizing Options - Six lengths (140mm/152mm/160mm/165mm/170mm/175mm) accommodate riders from 5'0" to 6'5", optimizing leg extension and power transfer for city commuting or mountain trails.
High-Torque Engineering - Forged 6061-T6 aluminum withstands 150Nm of force, preventing bending under mid-drive motor stress. Anodized coating resists chain slap scratches.
Universal Compatibility - Square taper hole (JIS standard) fits most electric bikes, including Bafang, Bosch, and Shimano mid-drive systems; compatible with 3-piece bottom brackets.
Easy Installation - Direct replacement for worn cranks; includes alignment marks for accurate pedal positioning. Note: Requires crank puller tool (sold separately).
Rider-Focused Design - Lightweight (420g/pair) reduces pedal inertia; textured inner surface prevents slippage on bottom bracket axles during high-cadence cycling.
