HKM-7387987 Kids 36V Electric Motorcycle - Off-Road Mini Bike with 350W Brushless Motor, Max Speed 40km/h, and Rear Disc Brake
HKM-7387987
Thirty-Six Volts, Brushless, Trail-Ready
The HKM-7387987 is a kids off-road mini bike built around a 350 W brushless motor and a 36 V 3.0 Ah lithium-ion battery. Top speed is governed at 24.85 mph (40 km/h), the rear disc brake delivers predictable stops on dirt and gravel alike, and the steel frame with ABS body panels carries riders up to 154.3 lb. The battery pack slides out of the frame for indoor charging and refills in 2-3 hours on the included smart charger.
Key Features
Six details that define how the HKM-7387987 is built and how it rides.
350 W Brushless Motor
Electronic commutation replaces wear-prone carbon brushes, so the motor runs quiet, runs cool and routinely clears 85 percent efficiency - with no motor maintenance on the calendar at all.
36 V 3.0 Ah Lithium-Ion
The 108 Wh pack carries more energy per pound than older chemistries, shrugs off partial charges with no memory effect, and an onboard BMS guards every cell against overcharge, over-discharge and shorts.
Removable Pack, 2-3 h Charge
The battery slides out of the frame, so it charges indoors while the bike stays in the garage, and the multi-stage smart charger refills it in 2-3 hours then holds a safe maintenance float.
Rear Disc Brake
A disc at the rear wheel shrugs off heat and sheds water and mud far better than a drum, and rear-only placement means a learning rider never fights front-wheel lockup mid-lesson.
Steel Frame, ABS Panels
A steel-tube backbone handles the loads and absorbs trail hits, while impact-tough ABS body panels resist scratches and UV fade through seasons of outdoor use.
154.3 lb Capacity
The chassis is rated to 154.3 lb (70 kg), a range that covers years of growing riders rather than a single season, with ergonomics proportioned for younger hands and legs.
Overview
A 36 V off-road mini bike with a brushless heart and a removable battery.
The HKM-7387987 pairs a 350 W brushless motor with a 36 V 3.0 Ah lithium-ion pack for quiet, responsive pull across packed dirt, gravel, short grass and woodland trails. Speed is governed at 24.85 mph (40 km/h), the throttle ramps progressively so new riders learn modulation before outright pace, and the rear disc brake brings consistent, predictable stops. The battery removes for indoor charging and refills in 2-3 hours, the steel-and-ABS chassis carries up to 154.3 lb, and four colourways - black, red, blue and yellow - keep the look as sharp as the hardware.
A Mini Bike Laid Out Like a Real One
Every control sits where a rider expects to find it.
Bars, brake lever, throttle and footpegs all sit in the positions a full-size bike uses, so nothing needs unlearning on the way up. The contoured seat supports both seated cruising and standing maneuvering over rough ground, and the progressive throttle maps wrist input to power in proportion - the single most useful trait a first off-road machine can have.
Full Specifications
What the motor, the battery and the chassis are made of.
Steel Where It Counts, ABS Where It Shows
The chassis hardware carries the same standard as the drivetrain.
The frame is fabricated from steel tubing chosen for fatigue resistance and impact absorption - the properties that matter when a trail throws up rocks, roots and ruts. ABS body panels take the scrapes that happen everywhere else, hold their colour under sun, and pop back to shape after minor knocks. Corrosion-resistant fasteners and reinforced connection points tie the two materials into one rigid structure, and the battery bay is positioned so the pack slides out without tools.

Why Choose the HKM-7387987
Six further reasons families choose the HKM-7387987.
No Brushes, No Fuss
A brushless motor has no carbon brushes to wear out, so the service checklist stays on tires, pads and fasteners - and the motor itself is effectively sealed for its design life.
Charge Where You Park
The removable 36 V pack means the charger comes to the outlet, not the bike - top up indoors overnight and roll out to a full 108 Wh in the morning.
Predictable Stops
The rear disc gives young riders one lever, one consistent bite and no front-wheel drama, which is exactly how braking confidence gets built on loose ground.
Colour That Stays
Black, red, blue and yellow finishes are applied in multi-layer coats bonded to the ABS and stabilised against UV, so the bike that looked sharp in the photos still looks sharp next season.
Terrain Range
Packed dirt, gravel, short grass and woodland trails are all within the tire profile's comfort zone, so one bike covers the driveway, the lot and the treeline loop.
Room Between the Limits
A governed 24.85 mph top end above a progressive throttle means the bike is calm at walking pace and composed at full tilt, with the whole learning curve in between.
Frequently Asked Questions
Quick answers about the HKM-7387987 mini bike.
How fast does it go?
Top speed is governed at 24.85 mph (40 km/h) with a full battery on flat ground. The throttle is progressive rather than on-off, so speed can be held far below the maximum while a new rider is still learning their limits. Actual pace varies with rider weight, terrain and charge level.
How long does the battery take to charge?
2-3 hours with the included smart charger from any household outlet. The charger runs a constant-current bulk phase to roughly 80 percent, tops off the rest gently, then settles into a maintenance float, so overnight charging is fine.
Can the battery be charged away from the bike?
Yes - the 36 V pack is designed to slide out of the frame, so it can charge indoors while the bike stays in the garage or shed. Always charge with the included smart charger or an approved equivalent.
Is it suitable for my child?
The 154.3 lb (70 kg) load rating covers a broad range of youth riders, and the controls are proportioned for younger hands. A certified helmet, gloves, long pants and closed-toe shoes are required every ride, adult supervision is strongly advised under age 14, and local rules on youth off-road vehicles should be checked first.
What colours does it come in?
Four: black, red, blue and yellow. The hardware is identical across the range - same 350 W brushless motor, same 36 V pack, same rear disc - so the choice is purely about which colour your rider claims.
Quick Troubleshooting
Common HKM-7387987 issues and what to check first.
The bike will not power on
Confirm the pack is fully seated in its bay first, because a partially inserted battery will not complete the circuit. If it is seated and still dead, put the pack on the smart charger for a full 2-3 hour cycle - a deeply drained pack needs a complete charge before it accepts normal use - and check the battery contacts for dirt or moisture while it is out.
It slows down on hills or soft ground
Some slowdown on steep inclines, deep grass and loose gravel is expected at any charge level, and a fading battery reduces output further. Test top speed on flat ground with a full charge, and confirm both tires are at the pressure printed on the sidewall, since soft tires drag hard on loose surfaces.
The rear brake feels weak
A new disc needs a short bedding-in period, so apply it firmly a few times at low speed in an open area and expect the bite to improve over the first week. If the lever stays soft, check that the rear wheel spins free with the lever released and that the rotor has not picked up mud or oil.
Runtime seems shorter than before
Range depends on rider weight, terrain and throttle habit, and a pack left uncharged for weeks delivers less than a freshly cycled one. Recharge fully after every session rather than topping up in part, store the pack at room temperature, and if runtime keeps dropping on identical routes, contact support with the purchase date to hand.
