Mid-Motor Architecture: Precision & Balance
At the heart of the HKM-467155 lies a centrally mounted 72V motor delivering 16.8 kW (22.5 hp) of peak output. Unlike hub-motor designs that add unsprung weight to the wheel, a mid-motor positions the mass near the bike's center of gravity. The result is superior suspension responsiveness, sharper cornering, and a ride feel that closely mirrors high-end combustion dirt bikes.
- Central mass placement reduces rotational inertia for agile handling
- Lower unsprung weight means the suspension tracks terrain more precisely
- Chain-driven rear wheel delivers instant torque with mechanical efficiency
- Peak power enables steep climbs and rapid acceleration out of corners
SAMSUNG 50S Cells: Industry-Leading Energy Density
The 72V 40Ah lithium battery pack is built around genuine SAMSUNG 50S 21700-format cylindrical cells—widely regarded as a benchmark for high-drain applications. With a total energy capacity of approximately 2.88 kWh, this pack delivers both sustained cruising range and the burst current needed for aggressive off-road riding.
- SAMSUNG 50S cells offer high discharge rates with minimal voltage sag
- 2.88 kWh total energy enables up to 75 miles (120 km) at a steady 15.5 mph (25 km/h)
- 21700 cell format provides superior thermal stability over 18650 alternatives
- Integrated BMS (Battery Management System) safeguards against overcharge, over-discharge, and cell imbalance
Understanding the 72V Architecture
A 72-volt system offers tangible advantages over lower-voltage platforms. Higher voltage reduces current draw for the same power output, which in turn lowers resistive heat generation in wiring and connectors. This means the HKM-467155 can sustain high power delivery during extended off-road sessions without thermal throttling—a critical factor when tackling long ascents or deep sand. The 40Ah capacity, realized through a multi-parallel cell configuration, ensures that range anxiety stays off your mind while you focus on the trail ahead.
4-Piston DOT Hydraulic Disc Brakes
Confidence in braking transforms how aggressively you can ride. The HKM-467155 is equipped with 4-piston hydraulic calipers on both front and rear wheels, using DOT-standard brake fluid for consistent performance across a wide temperature range. The front rotor measures 8.66 in diameter × 0.11 in thickness (220 mm × 2.8 mm), while the rear is 8.0 in diameter × 0.11 in thickness (203 mm × 2.8 mm)—a staggered sizing that reflects real-world braking dynamics where the front wheel handles the majority of stopping force.
- 4-piston calipers provide even pad pressure and superior modulation
- DOT hydraulic fluid resists boiling under sustained heavy braking
- Larger 220 mm front rotor maximizes heat dissipation and lever feel
- 203 mm rear rotor prevents lockup while retaining ample stopping power
19-Inch Wheels with Optimized Rim Width
The HKM-467155 rolls on 19-inch wheels with a 1.4-inch rim width, striking an ideal balance between low-speed maneuverability and high-speed stability on loose surfaces. The 19-inch diameter is a proven sweet spot in off-road motorcycling—large enough to roll over obstacles with confidence, yet not so large that it compromises quick directional changes. Combined with the mid-motor's centralized mass, this wheel setup delivers a planted, predictable feel through ruts, rocks, and berms.
- 19-inch diameter navigates trail obstacles with reduced deflection
- 1.4-inch rim width supports tire profiles suited to varied terrain
- Lightweight wheel assembly complements the agile chassis dynamics
- Proven geometry inspires confidence for both novices and seasoned riders

Engineered for the Trail
Beyond the headline numbers, thoughtful engineering choices make the HKM-467155 a standout in the electric dirt bike category.
Instant Torque Delivery
Electric motors produce peak torque from zero RPM—a fundamental advantage over internal combustion engines that need to build revs. On the trail, this translates to immediate throttle response when navigating technical sections, climbing loose surfaces, or recovering from near-stall situations. The mid-motor configuration ensures this torque reaches the rear wheel through a robust chain drive, with no belt slip to worry about in muddy or wet conditions.
Near-Silent Operation
One of the most liberating aspects of electric off-road riding is the dramatic reduction in noise. The HKM-467155 operates with a subtle whir rather than the exhaust bark of a combustion engine. This not only reduces rider fatigue on long days but also opens up riding areas with noise restrictions and minimizes disturbance to wildlife and other trail users. The experience is immersive—you hear the tires interacting with the terrain, the wind, and the environment around you.
Reduced Maintenance Burden
No oil changes, no air filter cleaning, no spark plug replacements, no carburetor tuning. The electric powertrain of the HKM-467155 dramatically simplifies the ownership experience. Routine maintenance is largely limited to chain lubrication, brake pad inspection, and tire pressure checks. For riders who would rather spend their weekends riding than wrenching, this is a transformative advantage that adds up to significant time and cost savings over the life of the bike.
Frequently Asked Questions
Find answers to the most common inquiries about the HKM-467155 electric dirt bike.
What real-world range can I expect from the HKM-467155?
Range varies significantly based on riding style, terrain, rider weight, and speed. At a conservative cruising pace of 15.5 mph (25 km/h) on level ground, you can achieve up to 75 miles (120 km). In mixed off-road conditions with aggressive throttle use, expect approximately 35–55 miles (55–90 km). Factors such as steep inclines, soft sand, and frequent acceleration will draw more current and reduce total range accordingly. We recommend planning your rides with a comfortable buffer.
How long does it take to fully charge the battery?
Charging time depends on the charger used. With a standard 10A charger, a full charge from empty typically takes approximately 4–5 hours. Using a 5A charger extends this to around 8–9 hours. The integrated BMS manages charging to protect cell health, and we always recommend using the manufacturer-supplied or approved charger to ensure optimal battery longevity.
What is the expected lifespan of the SAMSUNG 50S battery pack?
SAMSUNG 50S cells are rated for approximately 500–800 full charge-discharge cycles before capacity degrades to 80% of the original specification. Under typical recreational use, this translates to several years of reliable service. Partial discharges (e.g., charging from 30% to 80%) place less stress on the cells and can significantly extend the total cycle count. The BMS continuously monitors cell balance and temperature to maximize pack longevity.
Is the HKM-467155 suitable for beginners?
The HKM-467155 is a high-performance machine with substantial power. While experienced riders will immediately appreciate its capabilities, beginners should approach it with respect. We recommend new riders start in a lower power mode (if available), practice in open areas with predictable terrain, and gradually build confidence. The instant torque of an electric motor demands smooth throttle control—a skill that develops quickly with mindful practice. Always wear appropriate protective gear including a helmet, boots, and body armor.
How does the mid-motor compare to a hub motor for off-road use?
Mid-motors offer several key advantages for off-road riding. By placing the motor near the bike's center of mass and keeping it out of the wheel, unsprung weight is dramatically reduced. This allows the suspension to respond more effectively to bumps and ruts. Additionally, mid-motors deliver power through the chain drive, enabling gear reduction that multiplies torque at the rear wheel for superior climbing and acceleration. Hub motors, while simpler, add considerable rotating mass to the wheel, which negatively impacts suspension performance and handling agility on rough terrain.
What type of terrain is the HKM-467155 designed for?
The HKM-467155 is purpose-built for off-road environments including dirt trails, gravel paths, forest single-track, desert hardpack, and moderate rocky terrain. The 19-inch wheels, powerful mid-motor, and hydraulic braking system equip it to handle diverse conditions. It is not designed for paved-road commuting or highway use. As with any off-road motorcycle, riders should assess trail difficulty against their skill level and always ride within their limits.
