Sur-Ron Ultra Bee (2025) — 12.5kW Electric Off-Road Bike
The 2025 Sur-Ron Ultra Bee takes electric performance to the next level with a redesigned frame, a 74V battery system and a powerful 12.5 kW mid-drive motor delivering up to 440 N·m of torque at the wheel. Engineered for aggressive off-road riding, it pairs instant power and intelligent traction control with a refined long-travel suspension built for speed and control. Lightweight, durable and trail-ready, it's the choice for riders chasing cutting-edge electric performance. Available now at Inner City Scooters, Dublin, Ireland.
Next-generation electric off-road performance
The Ultra Bee steps up to full-size dirt-bike capability. Its 12.5 kW mid-drive motor punches out up to 440 N·m at the wheel for a blistering 0–50 km/h time of just 2.3 seconds and a top speed of over 90 km/h. Multiple ride modes, Sur-Ron's traction control (SRTC) and energy regeneration (SERS) keep all that power usable, while a forged aluminium frame and 240 mm of suspension travel soak up the roughest terrain.
12.5 kW mid-drive motor
A permanent-magnet synchronous mid-drive motor delivers 12.5 kW of peak power and up to 440 N·m at the wheel, launching the Ultra Bee from 0–50 km/h in just 2.3 seconds to a top speed of over 90 km/h.
74V 55Ah battery
The high-performance 74V 55Ah lithium-ion pack gives serious range — up to around 140 km in eco riding (roughly 100 km at a constant 50 km/h) — and recharges fully in about 4.5 hours.
Multiple ride modes
Eco, Daily, Sports and Reverse modes plus an adjustable throttle curve let you tune the Ultra Bee to the terrain and your skill level, from gentle trail cruising to full-attack riding.
SRTC traction & SERS regen
Sur-Ron's Traction Control System (SRTC) keeps power planted on loose surfaces, while the Energy Regenerative System (SERS) recovers energy and adds controlled engine braking.
Long-travel suspension
A high-spec front fork and TR rear suspension with hydraulic damping provide 240 mm of wheel travel, soaking up jumps, ruts and rocks for confident control at speed.
Hydraulic disc brakes
Front and rear hydraulic disc brakes deliver strong, repeatable stopping power to match the Ultra Bee's serious performance on demanding terrain.

What range and charge time can I expect?
The 74V 55Ah battery delivers up to around 140 km in eco riding, or roughly 100 km at a constant 50 km/h. Real-world range depends on rider weight, terrain, temperature and how hard you ride. A full charge takes about 4.5 hours.
