QS7 60Ah
QS7 Mechanical Disc Brake Setup
The QS7 comes with an exclusive 160mm mechanical disc brake system, paired with high-quality brake pads. This combination achieves excellent balance between braking efficiency and stable performance, reducing stopping distance noticeably. It provides reliable safety assurance and confident riding experience every time.
Equipped with 48V 60Ah High-Safety Battery
At Deepower, battery safety is always our top priority. Each battery pack features a scientifically optimized internal structure and is fully certified to MSDS, UN38.3, UN3171, UN3480, and UL2271 standards. Our thermal safety measures exceed industry benchmarks—even at extreme temperatures up to 156°F (approx. 65°C), they ensure zero risk of open flames or thermal runaway. The built-in thermal protection controller automatically cuts power during overheating, delivering comprehensive peace of mind and reliable safety protection for every ride.
1500W High-Power Motor
Deepower features a 1500W external rotor brushless DC motor paired with a three-level pedal assist system (PAS) for flexible riding control. It achieves a top speed of 32 mph (50 km/h) in the optimal PAS setting, balancing high performance with smooth power delivery. The motor features a sine wave structure design, ensuring low interference, quiet operation, and stable output. It boasts excellent high-temperature resistance and an exceptionally long service life (exceeding 200,000 hours), maintaining reliability in demanding environments and during extended rides.
High-Intensity Projector Headlight
The front headlight adopts a precision projector lens design, paired with three high-power LED bulbs. Its brightness is 30% higher than the previous generation, boasting an illumination range of up to 100 ft. The concentrated light beam delivers wider coverage while reducing glare, minimizing light scatter to enhance safety for oncoming pedestrians and vehicles.
Full Suspension System
The QS7 comes with a fully adjustable front and rear suspension setup, boasting a 80mm front fork travel. Matched with a precisely calibrated rear shock absorber, it smoothly dampens bumps and rough terrain. Compared to models without rear suspension, it enhances riding comfort by up to 50%, delivering a smoother and more enjoyable experience on any route.
