More about e*thirteen E-MTB Cranksets
E-MTB cranks need to be stronger, shorter, and compatible with your motor. We designed every e*spec crankset from the ground up for electric mountain bike demands.
Helix Race Carbon e*spec represents the pinnacle of ultralight e-bike crank design. ASTM 5 approved with weights as low as 320g. Light enough for trail and all-mountain, strong enough for shuttle days at the bike park. The highest strength-to-weight ratio crankset in the e-MTB world.
Helix Race e*spec Alloy offers premium performance without the carbon price tag. Forged and extensively CNC finished, tested to E-Enduro standards and suitable for Class 5 applications. A serious upgrade that increases strength and pedal strike resistance while reducing weight.
Helix Core e*spec delivers high-end integrity at a great value. Forged aluminum arms, self-extracting bolts, molded impact boots, and shorter lengths. All the features you'd expect from a crankset well above its price.
Wide motor compatibility across the line: Bosch® CX Gen4/5, Bosch® SX, Brose® S Mag, TQ® HPR50, Fazua® Ride 60, Avinox®, Yamaha®, Maxon®, and Specialized® SL 1.1, 2.2, and 3.1. Customizable offsets (21.5mm and 26mm) let you dial in Q-factor and ride feel.
