Sur-Ron Ultra Bee (74V 55Ah / 12.5kW)
Full-sized mid-weight enduro electric bike with 12.5kW peak power, 440Nm torque, and integrated traction control (SRTC).

Agile 3.7kW trail bike designed in Australia for singletrack flow, technical climbs, and silent bush exploration.
The Stealth F-37 Trail Fighter is the agile little sibling of the iconic Stealth B-52 Bomber — designed in Melbourne specifically for Australian singletrack, tight bush corridors, and technical trail sections where flickability and precise balance matter more than outright speed. Delivering 3.7kW through a 2-speed internal gearbox, the F-37 can navigate slow technical sections in low gear before opening up to 65 km/h in high gear on wide fireroads. Long-travel suspension absorbs Australian rock gardens and tree-root networks with confidence. At 44kg, it is lighter than any comparable electric trail bike with similar power, making it easy to manoeuvre in tight spaces and recover from tipover situations without assistance. The Australian-designed chromoly frame reflects real bush-riding heritage rather than European track-focused geometry. Available through Electric Dirt Bike Australia with 12-month warranty.
