Surron Ultra Bee


The All-New Surron Ultra Bee

Ultra Performance

Another daring endeavor, another significant breakthrough. The all-new Surron Ultra Bee, designed using feedback from the existing Bee family (Surron Light Bee) of electric bikes and racing over the previous few years, is here to redefine the electric off-road experience.

Out From Within

Inspired by its successful predecessors, Surron’s new Ultra Bee elevates electric performance to new heights. Surron’s most recent powertrain technology is at the heart of this mid-size powerhouse. The newly built platform provides precise lightweight handling, smooth power output, and incorporates Surron’s enhanced off-road traction control system (SRTC) to help you overcome obstacles on your ride.

Balancing On The Cutting Edge

Based on the design concept of “Balancing on the Cutting Edge,” the Ultra Bee matches an aluminum alloy forged chassis with Surron’s 4th generation powertrain, resulting in a weight of 187 lbs (85 kg) and even distribution.

New Innovative Powertrain

The Surron 4th generation powertrain was designed uniquely for Ultra Bee. Its special full isolated electrical architecture can avoid potential interference between high and low voltage circuit components. The combination of 74V55AH battery pack and 12.5KW / 440Nm torque drivetrain make the Ultra Bee a lighting quick track or trail weapon allowing you to push your limits to the maximum.

Power Packed

The Ultra Bee’s new 4,070Wh battery pack brings high power density and battery cycle life while achieving an even lower battery discharge temperature rate. This new design improves reliability and continuous discharge capability. A total weight of 45 lbs (20.5 kg) was achieved using an industry-leading power density of 200 Wh/kg.

Carry Power With You

A hidden space under the seat is designed specifically for the Ultra Bee’s charger. You can now carry your charger on your bike, giving you the ability to stop and charge anywhere you find an outlet.

Fully Adjustable Suspension

Featuring a newly-designed suspension system with 9.4 inches (240 mm) of travel front & back, the new Ultra Bee offers a wider range of adjustability for various conditions. The new forged aluminum frame’s dark green look helps the Ultra Bee further stand out in the crowd.
