HKM-647187 Electric Mountain Bike
High‑performance electric adventure machine — built to conquer any terrain with staggering torque, long‑range capability, and race‑bred components.
At the core of the HKM-647187 sits a high‑density 72V 45Ah lithium‑ion battery pack — engineered for endurance and consistent power delivery. With a formidable 3.24 kWh energy reserve, the bike achieves up to 93 miles (150 km) on a single charge under typical riding conditions. The advanced Battery Management System (BMS) continuously monitors cell voltage, temperature, and state of charge, protecting against over‑charge, deep discharge, and thermal stress. Whether you are traversing forest trails or commuting across town, the pack’s optimized energy density keeps you rolling longer between charges.
Smart BMS Protection
Multi‑layer safeguards ensure battery longevity and safety in all temperatures.
Range‑Optimized Cells
High‑grade 21700 cells deliver minimal voltage sag and extended cycle life.
The centrally mounted brushless motor delivers a staggering 500 Nm (369 lb‑ft) of torque directly to the drivetrain, translating into explosive acceleration and effortless climbing on gradients up to 35°. Unlike hub‑motor designs, the mid‑drive configuration preserves the bike’s balanced weight distribution and leverages the 5‑speed gearbox for optimal mechanical advantage. The result is a responsive, natural ride feel — whether you are crawling over technical rock sections or sprinting on open fire roads. The motor’s sine‑wave controller ensures whisper‑quiet operation and smooth power modulation.
Multi‑Layer Gear Reduction
Optimized internal gearing multiplies torque while keeping the motor compact and efficient.
Sine‑Wave Controller
Delivers fluid power delivery and near‑silent operation, reducing drivetrain stress.
Crafted from 6061 aluminum alloy, the frame strikes an ideal balance between rigidity and low weight, enabling nimble handling without sacrificing durability on punishing trails. The hydroformed tubes feature reinforced weldments at high‑stress junctions, while the geometry is tuned for aggressive all‑mountain riding. Paired with a full‑suspension system — featuring adjustable preload and rebound damping — the bike absorbs square‑edge impacts and successive bumps with poise, maintaining tire contact and rider confidence at speed.
6061 Aluminum Chassis
Precision‑welded frame with optimized strength‑to‑weight ratio for trail agility.
Adjustable Full Suspension
Tune compression and rebound to match terrain, from rock gardens to flow trails.
Stopping power is delivered by a set of high‑performance hydraulic oil brakes, featuring four‑piston calipers biting on large‑diameter stainless steel rotors. The system provides exceptional modulation and fade‑resistant performance, even during prolonged descents or emergency stops at top speed. Ergonomic levers offer reach adjustment, allowing riders to tailor the engagement point for maximum comfort and one‑finger braking capability. With a dual‑circuit layout, braking force remains balanced, enhancing stability when you need it most.
Equipped with a substantial 70/100‑19 wheel set (front and rear), the HKM-647187 rolls over obstacles with authority. The wide‑profile knobby tires (approximately 3.0‑inch section width) deliver a large contact patch for superior grip on loose soil, gravel, and mud. The 19‑inch rim diameter strikes a sweet spot between rollover capability and sidewall compliance, while the aggressive tread pattern sheds debris effectively. Whether cornering on hardpack or powering through sand, the tire and wheel combination inspires confidence at all lean angles.
The five‑speed transmission allows riders to select the perfect ratio for every situation — from steep, technical climbs that demand low‑end grunt to high‑speed sections where cadence and motor efficiency matter. The gearbox features dog‑clutch engagement for positive, reliable shifts, and is sealed against dust and moisture. The close‑ratio spread complements the motor’s broad torque curve, enabling smooth acceleration without power gaps. A gear position sensor communicates with the controller to optimize power mapping in each gear.
Every component of the HKM-647187 has been selected to deliver a no‑compromise off‑road experience. From the forged aluminum triple clamps to the stainless‑steel spokes, the build quality rivals that of premium downhill mountain bikes and light electric motorcycles. The integrated wiring harness is weather‑sealed, and all connectors feature gold‑plated contacts for corrosion resistance. A backlit LCD display provides real‑time telemetry — speed, battery state, gear position, and trip data — all visible in direct sunlight.
IP67 Weather Protection
Sealed electronics and connectors allow riding in rain, mud, and snow without risk.
Sunlight‑Readable Display
High‑contrast LCD with anti‑glare coating shows all vital data at a glance.
Regenerative Braking Ready
Optional regen mode captures kinetic energy during deceleration to extend range.
Multiple Ride Modes
Select Eco, Trail, Boost, and Walk modes to tailor power delivery and battery usage.
