SHIPPING DETAILS:
The 2025 Ultra Bee runs a powerful 74V system paired with a redesigned motor delivering 21kW peak and 18kW sustained. With FOC smart controller tech, precise torque management, and multiple throttle maps, it delivers instant acceleration, smooth modulation, and full rider control. Four regen levels and advanced traction assist give it serious brains behind the brawn.
Powered by a 74V 60Ah lithium-ion battery, the Ultra Bee delivers up to 70 miles of range at moderate speeds. The upgraded BMS offers thermal control and CAN communication for smarter energy use, while fast charging gets you from 20% to 80% in under 3 hours. It’s not swappable — but it’s built to go the distance without compromise.
With Turbo Mode engaged, the Ultra Bee hits a top speed of 60+ mph and rockets from 0–31 mph in just 2.0 seconds. The upgraded motor and hairpin winding improve both heat dissipation and efficiency, delivering high-end performance for serious riders who demand speed — on track, trail, or fire road.
Built around a forged aluminum alloy frame and now sporting a 50% stiffer fork, the Ultra Bee handles technical terrain and big hits with confidence. Hydraulic bump stops, refined damping, and 9.4" travel keep you planted, while the new 18" rear wheel improves grip, flex, and tire choice. From backyard laps to singletrack, it's built to handle it all.
