⚡ Overview

The 2025 Sur-Ron Ultra Bee is a high-performance electric trail / off-road bike that sits between the lighter Light Bee models and the larger Storm Bee in Sur-Ron’s lineup. It’s designed for riders who want serious power, long range, and versatile trail capability — whether carving through forest tracks or enjoying open terrain riding.

🏍️ Performance & Power

• Motor: Advanced permanent magnet synchronous motor with MTPA/MTPV controller delivering up to ~21 kW peak power (Turbo mode) and around 18 kW in Sport mode.

• Torque: Around approx. 376–511 Nm on the wheel, giving very strong low-end pull and acceleration.

• Top Speed: Around 95 km/h (59 mph) on unrestricted terrain.

• Ride Modes: Typically includes multiple ride settings — Eco, Daily, Sport, Turbo (and sometimes crawl / reverse modes) for adaptable performance.

🔋 Battery & Range

• Battery Pack: Large 74 V / ~60 Ah lithium-ion battery, optimized for energy density and durable performance.

• Range: Up to ~115 km or more depending on riding style and conditions.

• Charging: Around 2.5 – 4 hours for typical full charge cycles.

🛠️ Design & Construction

• Frame: Forged aluminum chassis that balances rigidity with relatively low weight (~88–92 kg).

• Suspension & Handling: Upgraded suspension components tuned for more aggressive trail riding and better stability at higher speeds.

• Brakes: Hydraulic disc braking system with strong stopping power for confidence on steep or technical trails.

• Tires & Wheels: Off-road-oriented tire setup (e.g., 80/100-19 front, 100/90-18 rear) for traction on varied surfaces.

🏍️ Riding Experience

The Ultra Bee is praised for its blend of robust power and manageable agility — offering plenty of torque for quick acceleration and steep climbs while still feeling balanced and responsive on trails. It’s larger and more capable than the Light Bee but easier to handle than the full-size Storm Bee, making it a great choice for intermediate to advanced riders looking for high-speed fun and versatile trail performance.

🚦 Variants (Optional)

There are versions that can be equipped with homologation gear (like the Ultra Bee T) or specific performance trims, meaning some models can also be suitable for road-legal use where permitted and meet requirements like L3e classification.
