Rundeer Electric Bike Engineered for Adventure and Athletic Performance
Certified Safety Meets Premium Power: Engineered for peace of mind, the Attack 11 is fully certified to UL 2849 and UL 2271, setting a new benchmark in e-bike safety. Its heart is a 960Wh removable Samsung lithium battery with IP65 waterproof protection. Lockable, fast-charging (5–6 hours), and built to last, this power source delivers up to 68 miles per charge—perfect for serious explorers and daily riders alike.



Precision-Engineered Aluminum Frame: The Attack 11 features a high-grade aluminum alloy frame with an extended design for enhanced stability and control. Its unique geometry optimizes riding comfort and handling, while the durable construction ensures long-lasting performance in demanding off-road conditions. Designed for strength, balance, and precision, the Attack 11 delivers a superior riding experience.

It features a Full Suspension System: The Attack 11 is equipped with the DNM USD-8FAT inverted air suspension fork, providing 160mm of travel for superior impact absorption and control. The air-hydraulic system enhances rigidity and responsiveness, while a 15mm thru-axle and reinforced seals ensure stability. Adjustable rebound and compression settings allow riders to fine-tune their suspension for optimal performance.

Fat Tires and Hydraulic Brakes: Ride with unmatched traction and comfort on 20×4″ puncture-resistant fat tires. Tektro 4-piston hydraulic disc brakes ensure powerful, responsive stopping in any condition. The integrated LED display shows speed, battery level, distance, and assist mode at a glance, while five pedal-assist levels and 7-speed shifting provide total ride control. A 13W high-lumen LED headlight dramatically improves night-time visibility.
