Silverback’s new Fat E‑Bike Alloy Crank is a purpose‑built, heavy‑duty upgrade engineered for the extreme torque, wide chainlines, and rugged conditions unique to fat e‑bikes. Forged from 6061‑T6 alloy with a 7075‑T6 chainring, it delivers exceptional stiffness, durability, and long‑term reliability while keeping weight low.

A reinforced Shimano‑compatible interface (EP6 / EP8 / EP801 / E7000 / E6100), optimized 75.6 mm chainline, and 234 mm Q‑factor ensure perfect power transfer on 197 mm rear ends, while replaceable 36T/38T chainrings, 104 BCD spiders, and optional bolt‑on chainguards make servicing and customization easy.

Finished in brushed anodised grey with Silverback’s signature cut‑out design and rust‑proof hardware, this 170 mm crank is built to withstand demanding terrain and daily use—offering OEMs and riders a reliable, high‑performance solution at an accessible price point.
