The 21kW Power Advantage

One of the standout features of the 2025 surron ultra bee is its 21kW electric motor. This power output places it at the top of its class in the lightweight electric dirt bike category. The instant torque delivered by the electric motor provides incredible acceleration, enabling riders to conquer steep inclines and launch over jumps with ease.

Unlike internal combustion engines, electric motors deliver 100% torque instantly. This means that the Ultra Bee’s 21kW motor doesn’t just perform well on paper — it translates into real-world performance that riders can feel from the moment they twist the throttle.

Advanced Battery Technology

The 74V 55Ah lithium-ion battery is another key innovation in the 2025 Ultra Bee. With improved energy density and thermal management, this battery offers both range and reliability. Riders can expect up to 87 miles (140 km) on a single charge, depending on terrain and riding style. Fast charging capabilities also ensure minimal downtime, with a full charge achievable in approximately 3 to 4 hours using Surron’s high-speed charger.

Moreover, the battery pack is removable, allowing for easy swaps during races or extended trail rides. This flexibility is ideal for competitive riders and long-distance adventurers.

Intelligent Control System

Surron has equipped the Ultra Bee 2025 with an intelligent controller system that monitors temperature, torque, and battery usage in real-time. Riders can choose from multiple riding modes — including Eco, Daily, Sport, and Boost — to suit their preferences and terrain conditions.

The Boost mode unleashes the full 21kW potential, offering thrilling performance for experienced riders. Meanwhile, Eco mode conserves battery power for extended range. This customizable power delivery enhances both safety and enjoyment, making the Ultra Bee adaptable for riders of all skill levels.

Chassis and Suspension

Lightweight but durable, the Ultra Bee’s aluminum alloy frame contributes to its agile handling. The suspension system is fully adjustable, allowing riders to fine-tune their setup based on weight, terrain, and riding style.

• Front Forks: 37mm inverted hydraulic forks
   

• Rear Shock: Multi-link mono-shock with preload, compression, and rebound adjustment
   

This premium-grade suspension ensures that the bike absorbs bumps and jumps with confidence, making it equally at home on rugged trails and motocross tracks.

Braking and Safety

With great power comes the need for reliable stopping. The Ultra Bee is fitted with hydraulic disc brakes on both wheels, providing excellent modulation and stopping power. The regenerative braking system also contributes to energy efficiency by converting kinetic energy back into battery charge during deceleration.

An optional traction control system helps newer riders maintain control in slippery conditions, while the LED display keeps essential information like speed, battery level, and mode clearly visible.

Eco-Friendly and Low Maintenance

One of the biggest advantages of the Surron Ultra Bee 2025 Electric Bike is its zero-emissions operation. Unlike gas-powered dirt bikes, it produces no fumes, no oil spills, and significantly less noise. This allows riders to explore natural trails without disturbing wildlife or violating noise regulations.

Furthermore, electric drivetrains require much less maintenance than traditional combustion engines. There are no oil changes, spark plugs, or air filters to worry about. Simply charge and ride — it’s that simple.

Riding Experience

Thanks to its well-balanced chassis, responsive motor, and intuitive control system, the Ultra Bee delivers a smooth yet exhilarating ride. Riders report an impressive level of confidence, especially when navigating technical trails or switching between riding modes on the fly. The 2025 model also includes upgraded ergonomics for a more comfortable riding stance and improved grip and controls.

Ideal for Various Riders

Whether you're a beginner, a commuter looking for a green alternative, or a professional trail rider, the 2025 Ultra Bee caters to a wide range of users. With adjustable power output and lightweight construction, it offers ease of use for novices while packing enough punch to satisfy even the most hardcore riders.

Its street-legal variants in certain countries (with added lights, mirrors, and indicators) also open the door for dual-purpose use — from commuting to weekend trail-blazing.

Price and Availability

The Surron Ultra Bee 2025 Electric Bike HP (21kW) is expected to be competitively priced around $6,999 to $7,499, depending on region and dealership. While not the cheapest e-bike on the market, the performance-to-price ratio is exceptionally strong given the advanced features and robust build.
