E5 High-Performance Electric Bike
E5 Mechanical Disc Brake Setup
The E5 features an exclusive 160mm mechanical disc brake system with premium brake pads. This combo perfectly balances braking efficiency and stability, noticeably shortening stopping distance for reliable safety and a confident ride every time.
Battery Safety is paramount. Each battery pack has a scientifically optimized internal structure and full MSDS, UN38.3, UN3171, UN3480, UL2271 certification. Our thermal safety measures exceed industry standards—zero open flame/thermal runaway risk even at 156°F (65°C). The built-in thermal protection controller cuts power on overheating, for total safety and peace of mind on every ride.
1500W High-Power Motor
1500W external rotor brushless DC motor + 3-level PAS enable flexible control, reaching 32 mph (52 km/h) in optimal mode with balanced high performance and smooth power. Its sine wave design delivers low interference, quiet, stable output, plus excellent high-temperature resistance and an ultra-long lifespan (200,000+ hours) for reliable performance in tough conditions and long rides.
High-Intensity Projector Headlight
The QS7’s front headlight has a precision projector lens design with three high-power LED bulbs—30% brighter than the last gen, with a 100 ft illumination range. Its concentrated beam means wider coverage, less glare and scatter, boosting safety for oncoming traffic and pedestrians.
Full Suspension System
The E5’s fully adjustable front & rear suspension (80mm front fork travel) pairs with a calibrated rear shock, smoothly dampening bumps and rough terrain. It boosts riding comfort by up to 50% vs. non-rear-suspension models, for a smoother, more enjoyable ride on any route.
Illumination,Headlight, Taillight, Brake Light & Emergency Light
High-power LED headlights (30% brighter, 100ft/30m beam) with horn; red emergency taillights (with turn signals) flash on brake for maximum safety.
Mechanical Gear Control
Shimano 7-speed gearing: low gears for easy climbs, high for smooth flats, paired with motor for hybrid riding. Responsive shifting boosts uphill torque, eases flat effort—perfect for commutes and casual outdoor rides.
20" x 4" Puncture Resistant Tires
20"x4" Sunrise puncture-resistant wide tires (deep tread for soft/slippery grip) and front suspension handle flat roads, mountain trails, snow, and gravel with ease—absorbing bumps to deliver a stable, worry-free ride anywhere.
LG Dual battery system
Powered by LG battery cells, the dual-battery setup (48V 25Ah + 35Ah) delivers reliable performance, pushing the maximum range to 185 miles (280km) for long rides without frequent recharging.
