Forged from 6061 aircraft aluminum alloy, the HKM-955603 frame achieves an optimal balance of lightness and structural integrity. The hydroformed tubing reduces weight while amplifying stiffness, enabling precise handling on technical descents and responsive cornering in traffic. Corrosion-resistant treatment and smooth welds ensure longevity in wet, muddy, or coastal environments.

The geometry is tuned for stability: a 47.8-inch wheelbase and 27.2-inch handlebar width inspire confidence at high speed, while the low standover height accommodates riders from 5'1" to 6'5". Integrated internal cable routing keeps the silhouette clean and protects wiring from trail debris.

The high-torque 3000W brushless rear hub motor delivers instantaneous response, reaching 25–37 mph (40–60 km/h) based on terrain and mode. It employs sine wave controller technology for ultra-smooth acceleration, eliminating jerky starts and extending component life. Whether climbing a 30° fire road or accelerating from a stoplight, the motor maintains quiet operation below 55 dB.

Three ride modes — Eco, Normal, and Sport — let you balance range and thrill. The thumb throttle on the left grip provides on-demand power, while the 5-level pedal assist senses cadence and torque, blending human and electric effort seamlessly.

Two independently removable 48V 20AH packs (total 40AH) provide an immense 1920 watt-hours. Ride up to 75 miles (120 km) on a single charge in Eco pedal-assist, or confidently tackle 45+ miles of throttle-only exploration. The Samsung/LG high-energy cells are managed by an advanced Battery Management System (BMS) that prevents overcharge, over-discharge, and temperature extremes.

Each pack locks securely to the frame with a key, and can be charged on or off the bike in 7–8 hours via the included 3A fast charger. The IP65-rated casing shields against rain, dust, and vibration, so you can charge confidently in a garage or at the office.

A MOZO adjustable front suspension fork with 100mm travel absorbs rocks, roots, and curbs, keeping the front wheel planted and your wrists fresh. Combined with 27.5" x 2.8" all-terrain fat tires, the bike floats over sand, snow, and loose gravel. The knobby tread pattern provides confident grip on wet pavement and dry singletrack alike.

Front and rear Tektro hydraulic disc brakes with 180mm rotors deliver consistent stopping power in all conditions. The brake sensors instantly cut motor power when levers are pulled, adding a layer of safety on steep descents.

The backlit 3.5-inch LCD dashboard keeps vital metrics in view: real-time speed, battery percentage, odometer, trip distance, assist level, and motor temperature. USB-A port under the display lets you charge a phone or GPS on the go. The intuitive button pad on the left handlebar allows mode changes without taking your eyes off the trail.

An optional Bluetooth module (sold separately) pairs with your smartphone to log rides, adjust power curves, and run diagnostics via the HKM E-Ride app.
