HKM-612115 72V Electric Motorcycle 20000W Lithium Battery Dirt Bike with 150KM Range and Hydraulic Brakes

HKM-612115 Electric Motorcycle

Precision engineering for off‑road mastery — silent torque, uncompromised endurance.

A 20,000‑watt brushless DC motor sits at the core of the HKM‑612115, converting electrical energy into immediate, linear thrust. The motor’s design eliminates mechanical commutation losses, raising efficiency and reducing maintenance. Peak torque of 368.8 lb‑ft (500 N·m) arrives with practically zero lag, giving you confident starts on steep inclines and rapid overtaking on open trails. The five‑speed gearbox lets you dial in the exact ratio for crawling over rocks or cruising at higher velocities, while the silent operation preserves the natural soundscape of your surroundings.

The 72‑volt 45‑amp‑hour lithium battery uses automotive‑grade prismatic cells arranged for optimal thermal management. A full charge delivers up to 93 miles (150 km) of range under mixed riding conditions — enough for a full day of trail exploration without anxiety. The intelligent Battery Management System (BMS) monitors individual cell voltages and temperatures, preventing overcharge, over‑discharge, and short circuits. Charging from a standard household outlet takes between 5 and 8 hours, and the pack is easily removable for convenient indoor charging or swapping with a spare.

Stopping power is delivered by hydraulic oil brakes on both wheels, providing consistent, fade‑resistant performance in wet or dusty conditions. A built‑in power cut‑off sensor immediately interrupts motor output when the brake lever is engaged, adding a critical layer of safety. The lightweight 147.7 lb (67 kg) chassis further shortens stopping distances, giving you precise control on downhill descents and technical singletrack. The system requires minimal maintenance — sealed hydraulics keep contaminants out and lever feel stays crisp ride after ride.

At just 147.7 lb (67 kg), the HKM‑612115 is remarkably agile. The twin‑spar aluminum alloy frame is robotically welded and heat‑treated, balancing high torsional rigidity with low weight. This allows quick direction changes, easier manual lifting over obstacles, and less fatigue during long rides. Despite its lightness, the frame meets rigorous stress‑test standards for off‑road use, so you can attack rough lines with confidence.

A fully adjustable suspension system — inverted front fork and rear mono‑shock — smooths out roots, rocks, and ruts. Generous travel absorbs harsh impacts, while rebound damping keeps the tires planted. The 70/100‑19 knobby tires (front and rear) offer a large contact patch, providing grip on loose gravel, mud, and hardpack. Their reinforced sidewalls resist punctures, so you can push harder on unknown terrain.

A high‑contrast LCD instrument panel keeps essential data at a glance: speed (mph or km/h), remaining battery percentage, trip distance, gear position, and motor temperature. Illuminated handlebar controls allow you to toggle between riding modes, adjust regeneration strength, and activate the LED headlight. The throttle response is calibrated to deliver smooth, predictable acceleration — ideal for both experienced riders and those transitioning from combustion bikes.
