Engineered to redefine off-road excitement, the HKM-103635 merges raw electric torque with agile chassis dynamics. Whether you are a veteran rider or a newcomer to dirt tracks, this machine delivers instant acceleration, silent operation, and zero emissions — all wrapped in a durable, lightweight package.

The heart of the HKM-103635 is a robust 6500W brushless DC motor, tuned specifically for off-road performance. Instant torque delivery eliminates the lag found in traditional combustion engines, giving you explosive acceleration from a standstill. A sine wave controller ensures smooth power modulation, reducing jerky throttle response and enhancing traction on loose surfaces. The powertrain is fully sealed against dust and water splashes, meeting IP65 standards for critical components, so creek crossings and muddy trails won't slow you down.

A 72V 30Ah lithium-ion pack provides 2160Wh of energy, carefully optimized for sustained trail riding. Depending on terrain, riding mode, and rider weight, you can expect a real-world range of approximately 41 – 62 miles (66 – 100 km) on a single charge. The battery uses automotive-grade 21700 cells and an advanced Battery Management System (BMS) that monitors temperature, voltage, and current in real time, protecting against overcharge, over-discharge, and short circuits. The pack is removable, allowing you to charge it indoors or swap in a spare for extended adventures.

A twin-spar aluminum alloy frame keeps dry weight at just 165 lbs (75 kg), making the bike nimble and easy to maneuver in tight single-track or rocky climbs. The front end features an inverted fork with 8 inches (203 mm) of travel, while the rear monoshock provides 9 inches (229 mm) of travel, both fully adjustable for compression and rebound damping. A ground clearance of 12 inches (305 mm) allows you to roll over logs and ruts without hesitation. The wheelbase spans 55 inches (1400 mm), striking a balance between high-speed stability and low-speed agility.

Stopping power comes from hydraulic disc brakes with 220 mm rotors front and rear, offering precise modulation and fade-free performance even during aggressive downhill runs. The 19-inch front and 18-inch rear off-road tires (70/100-19 and 80/100-18) feature deep, self-cleaning tread blocks that grip loose dirt, gravel, and hardpack equally well. A lightweight spoked wheel set absorbs impacts and reduces unsprung weight for better suspension response.

A backlit LCD display sits behind a protective lens, clearly showing speed, battery state of charge, odometer, trip meter, and selected riding mode. The display is daylight-readable and automatically adjusts brightness. An integrated LED headlight provides a sharp, wide beam for twilight rides, while the LED taillight enhances visibility to others. All lighting and electronics are powered directly from the main battery, eliminating the need for separate wiring or auxiliary batteries.

Every component has been selected for rugged off-road use. Stainless steel fasteners resist corrosion, while high-impact plastic body panels shrug off roost and branch strikes. The ergonomic seat, set at 34 inches (864 mm), accommodates a wide range of rider heights and allows easy weight shifts during aggressive cornering. The bike supports a maximum payload of 265 lbs (120 kg), making it suitable for adult riders carrying gear.

*Range varies based on riding mode, terrain, rider weight, and weather conditions.

Electric propulsion means near-silent operation, allowing you to enjoy nature without disturbing wildlife or other trail users. The absence of exhaust emissions makes this bike permitted in areas with strict environmental regulations. Regenerative braking contributes to energy efficiency during deceleration, subtly extending your range on hilly descents. The HKM-103635 is a modern solution for riders who demand performance without compromise.
