Surron's Flagship Electric Off-Road Machine
The Surron Ultra Bee is the most powerful electric dirt bike in the Surron lineup, and it is not close. With a hairpin-wound PMSM motor producing a staggering 21,000 watts of peak power in Turbo mode, this electric motorcycle accelerates from 0 to 31 mph in just 2.0 seconds flat. That is faster than most gas-powered dirt bikes costing twice as much. The Ultra Bee is engineered for riders who demand serious off-road performance from a zero emissions platform, with the advanced electronics and build quality to back it up on the most demanding trails.
At the heart of the Ultra Bee is a massive 74V / 60Ah battery pack built with premium Samsung and LG 21700 lithium-ion cells, delivering 4,440 Wh of total energy. In real-world trail riding conditions, expect approximately 60 miles of range per charge, with up to 71 miles possible under lighter use. That kind of endurance means full-day rides without range anxiety. The drivetrain uses a carbon fiber-reinforced belt running on tungsten carbide-coated pulleys, eliminating chain maintenance entirely while delivering smooth, silent power transfer. A full charge takes about 4 hours, and the bike includes built-in charger storage so you always have it with you.
Where the Ultra Bee truly separates itself from every other electric trail bike on the market is its suite of rider aids and riding modes. Six distinct modes give you total control over the riding experience: Turbo for maximum power, Sport for spirited trail riding, Daily for relaxed cruising, Eco for maximum range, plus a Reverse gear for tight trailhead parking and a Crawl mode for technical low-speed sections. The Surron Traction Control system (SRTC) monitors rear wheel slip and intervenes to keep you planted in loose or wet conditions, while the Surron Energy Regeneration System (SERS) captures braking energy and feeds it back into the battery. These are features typically reserved for premium electric motorcycles costing far more.
The suspension hardware matches the powertrain ambitions. A 37mm fully adjustable inverted fork up front and a TR Intersect monoshock in the rear each deliver 9.4 inches of travel, giving the Ultra Bee the suspension performance to tackle aggressive off-road terrain with confidence. Four-piston hydraulic disc brakes with 240mm rotors handle the increased speed and weight, and 12.5 inches of ground clearance means you can clear obstacles that would bottom out lesser bikes. The forged aluminum alloy frame keeps weight as low as possible at roughly 195 lbs, which is remarkable given the size of the battery and motor. For intermediate to advanced riders who want the most capable electric off-road bike available from Surron, the Ultra Bee is the definitive choice. No gas, no emissions, no compromise.
