More about e*thirteen E-MTB Components
Your motor opens up more trail. Our components make sure you get there.
More power starts with e*spec cranks. Shorter lengths for pedal clearance, reinforced construction for sustained torque, stiffer spindle interfaces that don't flex under load. Helix Race Carbon e*spec when grams matter. Helix Race and Core Alloy e*spec when budget does.
More speed comes from Helix cassettes. The 13-52T close-ratio was designed for E-MTB: the 13T cog paired with a 32T chainring delivers speeds just beyond motor cutoff at optimal cadence. Tighter gear steps help you clean technical climbs. For maximum range, 9-50T and 9-52T deliver up to 578%. Two-piece replaceable clusters. SRAM®, Shimano®, and TRP® compatibility.
More fun happens on Sidekick wheels. Pinkbike Innovation of the Year. Zero drag when coasting means you're faster. No kickback means smoother descents. Near-silent operation brings some zen back to the ride. Class 1 E-MTB compatible. Pair with Flux rims for compliance that handles the extra weight.
Turbocharger protects lightweight motors from rock strikes. Core e*spec chainguides keep your chain in place. Handlebars, stems, dropper posts, tires, and pedals for the complete build.
One brand. Every motor. Full confidence. 5-year warranty.
