Designed with 27.5-inch golden-size wheels, this off-road electric bike combines the obstacle-crossing ability of large wheels and the flexibility of small wheels. The 2.1-inch widened non-slip all-terrain tires effectively reduce rolling resistance and enhance grip, enabling stable and safe riding on urban pavement, mountain trails, gravel and rough roads, making it a versatile year-round E-MTB ebike.

✅ 160mm Dual Disc Brakes, Safe & Stable Ebike Braking System

This off-road electric mountain bike is fitted with front and rear 160mm mechanical disc brakes, featuring sensitive response and stable braking force.
