SURRON Ultra Bee UK

Another audacious endeavor, another historic discovery. The all-new Surron Ultra Bee UK is come to reinvent the electric off-road experience.

It was designed using knowledge from both racing and the current Bee series of electric bikes in UK.

OUT FROM WITHIN

The new Ultra Bee from Surron E Bike elevates electric performance to a whole new level, drawing inspiration from its

well-received predecessors. The latest powertrain technology from Surron E Bike in the UK is the foundation of this mid-sized

powerhouse. To assist you overcome obstacles on your journey, the recently built platform incorporates Surron E Bike UK’s

enhanced off-road traction control technology (SRTC) and offers smooth power output and precise lightweight handling.

On the trails, a revised, race-inspired braking system will provide you more stopping power, while the redesigned front

suspension and special TR rear suspension will encourage you to ride more confidently and go faster and farther.

BALANCING ON THE CUTTING EDGE

Designed with the idea of “Balancing on the Cutting Edge,” the Ultra Bee combines Surron’s 4th-generation

motor with an aluminum alloy forged chassis to produce an even weight distribution of 187 lbs (85 kg).
