Featured Highlights

Ride Smarter with PWR+ Torque Sensor Technology

The VIPER PLUS features a precision-engineered torque sensor with advanced PWR+ technology, intelligently adjusting power output based on your pedaling effort. This not only makes your ride feel more natural and intuitive but also helps extend battery life—giving you more miles per charge. Unlike basic cadence sensors, the torque sensor responds in real time to how hard you pedal, delivering smoother acceleration and easier access to Class 3 speeds with greater control. It’s the perfect blend of performance and efficiency, amplifying your effort without taking away the ride.

Quiet Strength, Built to Last

The VIPER PLUS delivers whisper-quiet power with a peak output of 1200W and a high-capacity 48V 20Ah battery, offering strong torque and smooth, efficient performance. Its upgraded brushless motor is designed for long-term reliability, requiring minimal maintenance while providing excellent heat dissipation—even during demanding rides. To keep the motor in top condition, avoid extended use in extreme heat, lubricate the motor bearings if accessible, and steer clear of heavy rain to minimize the risk of moisture-related damage.

Long-Range Power You Can Count On

The VIPER PLUS is equipped with a 48V 20Ah removable lithium-ion battery designed for longevity and performance. With over 800 charge cycles, it delivers up to 78 miles on pedal-assist and 40 miles on full electric mode—perfect for both daily commutes and off-road adventures. The integrated Battery Management System (BMS) offers intelligent protection against overheating and potential hazards, ensuring safe operation every time you ride. Backed by a 1-year warranty, this battery provides both power and peace of mind. For optimal performance, charge in temperatures between 0–45°C and ride in conditions ranging from -20°C to 60°C, ideally at room temperature.

Full Suspension for a Smoother, Stronger Ride

The VIPER PLUS is built with a full suspension system designed to absorb shocks from rugged terrain, giving you maximum comfort and control wherever you ride. Its front fork is both lockable and adjustable, allowing you to fine-tune performance based on the surface beneath you. Whether you're cruising over rocky trails or navigating city streets, the suspension system reduces fatigue and keeps your ride smooth, stable, and enjoyable from start to finish.

Smart Display, Total Control

The VIPER PLUS features a vibrant color display that clearly shows your speed, battery level, total mileage, and pedal-assist level—all at a glance. Fully programmable, it allows you to customize speed limits and safety settings to match your riding style. Seamlessly integrated with the bike’s mechanical pedaling system, the display offers real-time feedback and responsive control. Designed for visibility, it remains easy to read even in bright sunlight, so you stay informed and in command on every ride.

Smooth, Reliable Braking with Hydraulic Disc System

The VIPER PLUS is equipped with hydraulic disc brakes designed for quick, responsive stopping power and reduced hand fatigue—even on long rides. These brakes use mineral oil, offering excellent moisture resistance and minimizing the risk of corrosion. The result is long-lasting, stable braking performance with enhanced compatibility for seals and hoses, giving you confidence and control in all weather and terrain conditions.

Premium Traction with Every Turn

The VIPER PLUS rolls on high-quality Chaoyang fat tires, built for durability and all-terrain performance. Designed with reflective sidewall striping for added visibility and a dual tread compound for extended wear, these tires grip confidently in wet, loose, or uneven conditions. Whether you're cruising over city streets, gravel trails, or forest paths, they deliver a stable, secure ride that inspires confidence wherever you go. For optimal performance, maintain tire pressure between 18–20 PSI. Heavier riders may benefit from slightly higher pressure for added support and safety, while reducing PSI on rougher terrain can improve grip, absorb bumps, and enhance overall comfort.
