Dual-suspension comfort for mixed-surface riding
The EUNORAU DEFENDER is a full-suspension electric mountain bike built for riders who want a more forgiving ride on rough pavement, gravel connectors, and light off-road routes. The 27.5×3.0 tire setup adds stability and traction, while the rear air shock helps take the edge off repeated bumps and chatter.
Choose from 17" or 19" frame sizes and three colorways to match your preferred fit and finish.
