Engineered for Performance & Control
750W Brushless Rear Hub Motor
The HKM‑523411 is propelled by a refined 750‑watt brushless motor that delivers immediate, linear torque. Whether you’re tackling a 15% grade or accelerating from a standstill at a traffic light, the motor responds without lag. The brushless design reduces maintenance and ensures quiet operation — you’ll notice the wind, not the motor. Integrated thermal management keeps performance consistent even during extended climbs.
Combined with the twist throttle, you can call upon full power instantly. The motor’s efficiency is optimized through the 48V 25A intelligent controller, which balances output with battery conservation. Peak efficiency is achieved in Assist Mode, where the torque sensor multiplies your pedal input seamlessly.
48V 15Ah High‑Capacity Lithium Battery
The removable 48‑volt, 15‑amp‑hour lithium pack uses premium 18650 cells arranged in a sealed, impact‑resistant enclosure. A sophisticated Battery Management System (BMS) guards against over‑charge, over‑discharge, short‑circuit, and temperature extremes, prolonging the overall lifespan. Under typical riding conditions in Pedal‑Assist Mode, you can expect a range of up to 35 miles (56 km), while pure throttle operation may yield around 20 miles (32 km) — actual results vary based on terrain, rider weight, wind, and assist level.
Charging is straightforward: a standard household outlet replenishes the battery in approximately 5–6 hours. The pack can be charged on or off the bike, adding convenience for apartment dwellers or office commuters. LED indicators on the charger and the SW900 display keep you informed of charging status.
26‑Inch 6061 Aluminum Alloy Frame
Crafted from double‑butted 6061 aluminum, the frame achieves an impressive strength‑to‑weight ratio. Weighing significantly less than comparable steel frames, it retains the stiffness needed for precise steering and power transfer. The 26‑inch wheel size strikes a sweet spot between nimble trail handling and stable road manners. Internal cable routing reduces clutter and protects shift and brake lines from snags.
The geometry is tuned for comfort over long distances — a slightly upright posture eases pressure on the lower back without sacrificing control. Combined with a front suspension fork (if equipped, please refer to your package), the frame absorbs chatter from gravel and roots, keeping the tires planted. With a maximum payload capacity of 330 lbs (150 kg), the HKM‑523411 accommodates a wide range of riders and cargo configurations.
Front & Rear Mechanical Disc Brakes
Dual mechanical disc brakes provide reliable stopping power in wet, dry, or dusty conditions. Unlike rim brakes, disc brakes maintain consistent performance when the wheels are muddy or after prolonged descents. The front and rear 160mm rotors (typical specification) dissipate heat quickly, reducing fade on long downhill sections. Levers are reach‑adjustable to suit different hand sizes, enhancing comfort and control.
Maintenance is straightforward — cable‑actuated calipers are easy to adjust and service, with no hydraulic fluid to bleed. When you need to stop confidently with a full load, the HKM‑523411 answers with linear, predictable braking.
7‑Speed Shimano‑Style Drivetrain
A 7‑speed rear derailleur and thumb shifter let you quickly adapt to changing gradients. The gear range is wide enough to spin comfortably up steep inclines and to push a brisk cadence on flat tarmac. Shifts are crisp and precise, thanks to a well‑tensioned chain and index‑shifting mechanism. The single front chainring simplifies operation and reduces chain drop risk.
When you combine the mechanical advantage of the lower gears with the motor’s assistance, even the most daunting hills become accessible. You stay in full control of your effort level — shift down for a workout, shift up for speed.
SW900 LCD Display & Intelligent 48V 25A Controller
The backlit SW900 LCD screen is your command center. It shows current speed, total distance, trip distance, battery gauge, assist level (0–5), and wattage output — all legible even in direct sunlight. The interface is navigated via a remote button pod near the left grip, so your hands never leave the handlebar.
Behind the scenes, the 48‑volt 25‑amp sine‑wave controller feeds the motor with smooth, efficient current. This reduces the “jerkiness” some e‑bikes exhibit when the motor engages. It also supports regenerative‑style energy recovery in certain modes, gently feeding a trickle charge back to the battery on descents or when coasting.
Three Riding Modes & Twist Throttle
Tailor each ride to your mood and terrain: Pedal Mode turns off motor assist entirely — you’ll experience the bike as a traditional 7‑speed mountain bike, perfect for exercise or extending battery life. Assist Mode amplifies your pedaling effort across five levels, letting you dial in just the right amount of boost. Power Mode (throttle‑only) delivers maximum acceleration up to 31 mph (50 km/h) without pedaling — ideal for quick trips or when you want a rest.
The right‑hand twist throttle is ergonomically shaped and requires a natural wrist motion. It provides progressive control, meaning partial twist yields moderate speed, while full twist unleashes the motor’s full potential. A safety cut‑off switch in the brake levers instantly disengages motor power whenever you brake.
Robust 330 lbs (150 kg) Load Capacity & Rider Fit
The frame, wheels, and components are rated for a combined rider and cargo weight of up to 330 pounds. This generous capacity ensures solid stability and durability even when carrying panniers, backpacks, or a child seat (where legally permissible). The 26‑inch wheels, with a standover height that comfortably fits riders from approximately 5′3″ to 6′2″ (160–188 cm), make the HKM‑523411 accessible to a broad audience.
The saddle and grips are designed with dense yet forgiving foam, reducing fatigue on longer excursions. Quick‑release seatpost clamp allows tool‑free height adjustments, so multiple family members can share the bike with ease.
