HKM-665683 36V 13Ah Electric Bike
Precision-engineered for urban explorers and trail enthusiasts. Where robust power meets refined suspension intelligence.
Dynamic Rear Hub Drive
350W Nominal Power
High-torque rear hub motor delivers swift acceleration and sustained climbing capability. Peak output handles demanding inclines with composure.
Top Speed 18.6 – 31 mph
30 – 50 km/h velocity range adapts to open roads and controlled bike lanes. Three ride modes let you balance range and thrill.
The motor’s 70–80 Nm (51.6 – 59 lb‑ft) torque output means confident hill starts and steady momentum on loose surfaces. Riders experience immediate response the moment they engage the throttle or pedal assist, blending human effort with electric precision seamlessly.
Lithium Core Energy System
36V 13Ah (468 Wh)
Integrated downtube battery with smart BMS guards against overcharge, over-discharge, and temperature extremes. Lockable, removable design.
Range 19 – 37 miles
31 – 60 km on a single charge, depending on assist level, terrain, and rider input. Ideal for daily commuting or extended weekend exploration.
Real‑world testing shows that in ECO mode on flat paved roads, range can exceed 37 miles. The battery recharges in approximately 5–6 hours with the included 2A smart charger, so you can top up overnight and be ready for the next ride.
Full Suspension, Engineered for Comfort
ZOOM Front Fork – 100 mm Travel
3.9 inches of responsive suspension absorbs potholes and roots. Preload adjustment tailors the ride to your weight and terrain preference.
KS-A5 Rear Shock – 165 mm Travel
6.5 inches of rear cushioning keeps the wheel planted. Progressive spring rate copes with big hits and small chatter alike.
The full suspension system isn't just about comfort—it maintains tire contact for safer braking and cornering. Whether you're crossing tram tracks or venturing onto gravel, the HKM-665683 stays composed and predictable.
Precision Braking with Motor Cutoff
Promax Disc Brakes
Mechanical disc rotors front and rear deliver consistent stopping power in wet or dusty conditions. Low maintenance and easy to adjust.
Brake Lever Cutoff Switch
Instantly disengages motor power when braking, preventing unintended acceleration and preserving brake pad life.
The brake lever integrated safety switch adds an extra layer of control, especially useful in stop‑and‑go city traffic. Riders can modulate stopping force with confidence, knowing the system reacts in milliseconds.
7‑Speed Drivetrain & Ergonomic Pedals
7‑Speed Gear Set
Smooth, indexed shifting via a thumb shifter. Find the perfect cadence for steep climbs or fast flats without breaking rhythm.
Folding Nylon Pedals
High-strength composite pedals fold for compact storage. Non‑slip pins keep feet secure even when trails get muddy.
The wide 7‑speed gear range pairs perfectly with the electric assist, letting you extend battery life by pedaling efficiently. The pedals’ folding design is a thoughtful touch for apartment dwellers or anyone who transports their bike in a car trunk.
Lightweight Alloy Frame & All‑Terrain Tires
Aluminum Alloy Frame
6061 aluminum construction balances low weight with high torsional rigidity. Smooth welds and internal cable routing enhance the clean aesthetic.
27.5 × 3.0″ Tires
Plus‑size tires provide a large contact patch for grip on pavement, dirt, and gravel. The volume acts as passive suspension, smoothing out small irregularities.
The oversized 27.5‑inch wheels with 3.0‑inch wide tires deliver a stable, confidence‑inspiring ride quality. Lower tire pressure capability (20–30 PSI) means fewer flats and a cushioned feel without the weight penalty of a fat bike.
Intelligent 500S LCD Display
Backlit LCD Readout
Sunlight‑visible display shows speed, battery level, assist mode, trip distance, and odometer. Intuitive button interface on the handlebar.
Smart Assist Levels
Select from 0–5 pedal assist levels or use the throttle for pure electric propulsion. Real‑time wattage monitoring helps you manage consumption.
The display also provides error code diagnostics, making troubleshooting straightforward. Its compact, waterproof design withstands rain and vibration, ensuring reliable performance ride after ride.
