The Sur-Ron Light Bee X is a versatile and popular electric dirt bike that blends the agility of a mountain bike with the power of a motorcycle. It is known for its lightweight forged aluminum frame and high-performance electric powertrain, making it a thrilling off-road vehicle for both beginners and experienced riders.
Performance and power
- Top speed and acceleration: The latest 2025 models offer a peak power output of 8 kW, enabling a top speed of around 75 km/h (46.6 mph) and a 0–50 km/h (0–31 mph) acceleration in just 2.7 seconds.
- Motor and torque: It is powered by a high-performance PMSM brushless DC mid-motor and an FOC sine wave controller. The powerful motor delivers instant torque, with the 2025 model producing up to 266 N⋅m at the wheel.
- Riding modes: Riders can switch between two riding modes: Eco and Sport. Sport mode unleashes the bike’s full power, while Eco mode is better for preserving battery life.
- Climbing ability: The bike is capable of climbing gradients of over 45 degrees, making it suitable for tackling steep inclines and challenging off-road trails.
Battery and charging
- Removable lithium battery: The Light Bee X uses a removable 60V 40Ah lithium-ion battery pack, with some earlier models having a 32Ah or 38Ah capacity.
- Range: It has a typical range of around 75 km (46.6 miles) when cruising at 40 km/h, though the range can be shorter in Sport mode or tougher terrain.
- Fast charging: The battery can be charged from 20% to 80% in as little as 2 hours with a fast charger. Full charges generally take about 3 to 4 hours.
Chassis and suspension
- Frame: The bike features a lightweight forged aluminum alloy frame that is both durable and agile.
- Suspension: It comes equipped with an adjustable off-road suspension system. The 2025 model, for example, has an inverted hydraulic fork in the front with 200mm of travel and an adjustable multi-link rear suspension.
- Brakes: For reliable stopping power, the Light Bee X has 4-piston hydraulic disc brakes on both the front and rear wheels.
Features and variations
