High-Performance Electric Dirt Bike — Engineered for Off-Road Exploration and Everyday Adventure
A remarkable blend of endurance, torque-rich propulsion, and rugged durability. Designed for adventure seekers who demand reliability across diverse terrains—from forest trails to desert paths—and everyday riders seeking a thrilling, zero-emission commute. The HKM-365779 redefines what an electric dirt bike can deliver, combining a high-capacity dual-battery system, a robust central motor, and advanced safety features into one cohesive machine.
⚙ Powertrain & Motor Technology
At the core of the HKM-365779 lies a meticulously engineered mid-drive motor system that prioritizes balanced weight distribution and responsive power delivery.
Central Mid-Drive Motor
The centrally positioned motor delivers an impressive 249.3 lb-ft (338 N·m) of peak torque, channeling power through a robust drivetrain for authoritative acceleration. Unlike hub-motor designs, this mid-drive configuration keeps the center of gravity low and centered, resulting in superior handling dynamics, enhanced traction on loose surfaces, and a more natural riding feel that experienced riders will immediately appreciate. The motor’s internal permanent-magnet architecture ensures high efficiency across a broad RPM range, converting electrical energy into mechanical output with minimal losses.
The three-speed gear system allows riders to tailor output characteristics—select lower gearing for technical hill climbs that demand maximum torque multiplication, or higher gearing for relaxed cruising on flatter trails. This mechanical advantage multiplies the motor’s inherent capability, giving the HKM-365779 the versatility to conquer steep inclines and maintain efficient speed on open paths alike.
🔋 Understanding 249.3 lb-ft (338 N·m) of Torque
Torque is the rotational force that propels the bike forward from a standstill and pulls it up gradients. At 249.3 lb-ft, the HKM-365779’s torque output rivals that of much larger internal-combustion dirt bikes, yet it’s delivered with the instant, silent character unique to electric propulsion. There’s no clutch to feather, no gear to hunt for—just seamless, controllable thrust from the moment the throttle is engaged. This makes the bike exceptionally capable on challenging terrain where immediate power delivery can mean the difference between clearing an obstacle and losing momentum.
🔌 Dual-Battery Architecture & Range
Endurance meets convenience with a high-voltage dual-battery configuration designed for extended adventures.
60V18AH × 2 Configuration
Total combined capacity of 36Ah delivers up to 87 miles (140 km) of range on a single full charge—enough for a full day of trail riding or multiple days of casual exploration without range anxiety.

Both battery packs are fully detachable, enabling convenient off-bike charging in any standard outlet. The modular approach also means you can carry a spare set for even longer expeditions or replace packs independently over the product lifecycle.
Lithium-Ion Cell Technology
High-density lithium-ion cells with an advanced Battery Management System (BMS) that monitors voltage, temperature, and charge cycles in real time. The BMS safeguards against overcharge, over-discharge, and thermal anomalies, prolonging battery lifespan and ensuring consistent performance across thousands of cycles.
Smart Energy Management
The onboard energy controller optimizes power flow between the dual batteries, balancing discharge rates to maximize range and minimize cell stress. Regenerative capability recaptures kinetic energy during deceleration, feeding it back into the battery pack—extending range in stop-and-go riding scenarios.
🛡 Hydraulic Disc Brakes — Precision Stopping Power
Confidence-inspiring braking performance is essential for off-road riding, where conditions can shift from dry hardpack to loose gravel or mud in an instant. The HKM-365779 is equipped with a hydraulic disc brake system engineered for modulation, consistency, and fade resistance.
Hydraulic Actuation for Superior Modulation
Unlike mechanical cable-actuated brakes, hydraulic disc brakes use fluid pressure to transfer force from the lever to the caliper pistons. This results in a lighter lever feel, more progressive bite, and significantly improved modulation—giving the rider fine-grained control over braking force. Whether you’re feathering the brakes on a loose descent or executing a controlled stop on pavement, the system responds with linear, predictable feedback.
The large-diameter rotors provide ample thermal mass to dissipate heat buildup during prolonged braking, maintaining consistent performance even on extended downhill runs. Sealed hydraulic lines resist contamination from mud, dust, and water, ensuring reliable operation in all weather conditions with minimal maintenance requirements.
🏁 Off-Road Tires & Traction Engineering

Tire Specifications & Terrain Compatibility
The 70/100-19 sizing denotes a tire with a 70 mm section width and a 100% aspect ratio (sidewall height equals section width), mounted on a 19-inch rim. This profile—common in off-road motorcycle applications—provides a tall, compliant sidewall that absorbs trail irregularities while the aggressive tread pattern bites into loose soil, sand, and gravel. The generous contact patch enhances stability during cornering and braking, while the knobby tread design efficiently sheds mud to maintain traction in wet conditions.
The 19-inch front and rear wheel combination strikes an optimal balance between roll-over capability for obstacles and responsive steering geometry. This setup is widely regarded in the dirt bike community as the sweet spot for mixed-terrain riding, offering enough gyroscopic stability for high-speed sections without sacrificing the agility needed for tight singletrack.
Aggressive Tread Pattern
Deep, widely spaced knobs provide maximum bite on soft terrain while self-cleaning in muddy conditions, ensuring consistent grip throughout the ride.
19-Inch Wheel Platform
The 19-inch rim diameter provides enhanced roll-over capability for rocks and roots, paired with a compliant sidewall that absorbs trail chatter.
