Description

The 2025 Sur-Ron Ultra Bee represents the newest evolution of Sur-Ron’s mid-size electric motorcycle platform, delivering a powerful blend of motocross performance, enduro capability, and advanced electric engineering.

Designed for riders who want more speed, more torque, and more control than the Light Bee series, the Ultra Bee stands firmly in its own category, light enough to be playful, powerful enough to compete, and intelligent enough to adapt to any terrain.

Powered by Sur-Ron’s latest high-output electric powertrain, the 2025 Ultra Bee features a refined mid-drive motor that delivers instant torque for explosive launches, steep hill climbs, and confident acceleration on any surface. The updated FOC vector controller provides ultra-smooth throttle response, traction optimization, and real-time power delivery adjustments, allowing both beginners and experienced riders to maximize performance safely and effortlessly.

The Ultra Bee’s 74V lithium battery pack offers significantly increased capacity, higher discharge rates, and improved thermal stability for longer ride times and consistent power. Fast-swap capability and efficient charging make it ideal for trail sessions, race days, and extended off-road adventures.

Built on a premium lightweight aluminum alloy frame, the 2025 model introduces chassis refinements that enhance rigidity, cornering precision, and high-speed stability. The long-travel adjustable suspension system—paired with advanced linkage geometry—absorbs aggressive impacts, jumps, and rough terrain with ease. Hydraulic disc brakes with large rotors provide strong, reliable stopping power even under extreme conditions.

The Ultra Bee also incorporates next-generation electronics, including advanced traction control, rider-configurable power modes, regenerative braking, and a modern digital display offering real-time telemetry. With a quiet electric motor, zero emissions, and ultra-low maintenance requirements, the 2025 Ultra Bee is built for pure riding enjoyment with minimal downtime.

The result is a versatile machine that thrives on motocross tracks, single-track trails, forest roads, and open terrain—an electric motorcycle engineered for riders who demand top-tier performance without the weight and maintenance of a full-size gas bike.
