HKM-2761939 12-Inch Electric Balance Bike for Kids 3-8 Years with 250W Brushless Motor, 36V Lithium Battery and Rear Disc Brake
HKM-2761939
Two Batteries, One Serious Little Bike
The HKM-2761939 arrives with a choice: a 24V pack for gentle first rides or a 36V pack for riders who have already found their balance. Either way, the same 250W brushless hub motor turns the rear wheel, the same drop-down mount holds the battery low in the frame, and the same rear disc brake brings everything to a stop with one lever. The aluminium frame keeps the bike light, the saddle adjusts as the rider grows, and the 12-inch knobby tires turn lawns and gravel paths into proper riding ground, all wrapped in a motorcycle-in-miniature stance.
Key Features
Six details that make the HKM-2761939 easy to live with.
Two Battery Options
The same bike takes a 24V or a 36V lithium pack, so the purchase can match the rider instead of the other way round. Start calm with 24V, move up to 36V as the confidence grows, and keep the same frame, brake and motor throughout.
A Drop-Down Mount
The battery lives low in the frame and releases from its mount in one motion, which keeps the weight where handling wants it and charging off the bike. The pack goes indoors to the bench, and the bike stays in the hallway ready for the next ride.
A 250W Brushless Hub
The motor sits in the rear wheel, so drive goes straight into the tire with no chain to oil and nothing hot near small legs. It pulls evenly from a standstill, stays quiet through residential streets, and shrugs off grass and gravel without complaint.
A Rear Disc Brake
One lever and one disc keep the stop simple for a small hand. The bite arrives early in the lever travel and repeats identically every time, which is what lets a young rider build real braking judgement instead of just grabbing and hoping.
A Saddle That Moves
The saddle adjusts through a useful range, so a three-year-old starts with feet flat and a taller rider keeps the same bike longer. One clamp sets the height, and the job takes seconds before a session rather than an afternoon with tools.
Parts Support
The bike is built from standard bicycle parts where it counts: forks, levers and fasteners that a regular bike shop recognises. Wear items stay available and inexpensive, which keeps a season of hard playing from turning into a season of waiting for spares.
Overview
A 12-inch electric balance bike with 24V or 36V power and a rear disc brake.
The HKM-2761939 is a 12-inch electric balance bike for riders aged three to eight, offered with a 24V or a 36V lithium battery to match the rider’s stage. A 250W brushless motor in the rear hub drives the wheel directly, and a rear disc brake provides one consistent, easy-to-learn stop. The pack drops from its under-frame mount for bench charging, keeping weight low and the routine simple. Two speed modes let a parent tune how eagerly the throttle answers, the saddle adjusts through a wide range, and the aluminium frame with knobby 12-inch tires takes grass, gravel and pavement in its stride. It is a compact, tidy package for families who want a first powered bike that grows with the rider.
Battery Out, Charger On
One motion, and charging moves indoors.
The pack releases from its drop-down mount and comes inside for bench charging, so the bike never needs to sit beside a socket. Weight stays low where handling likes it, and the latch seats with a click you can feel through the palm.

How It Rides, Where It Rides
A bike that behaves the same every session.
Consistency is what makes a first powered bike work, and the HKM-2761939 is built around it. The 250W hub answers the throttle the same way at the start of a ride as at the end, because the brushless motor does not fade the way a cheap brushed unit does. The rear disc gives the same bite in dry grass as on the driveway, so braking becomes a habit rather than a calculation. The low battery mount keeps the centre of gravity near the axle line, which is why the bike leans predictably instead of wobbling, and the knobby tires translate all of that into straight tracking on ground that would have a slick tire wandering. It is a tidy, repeatable machine, which is exactly what a first powered bike should be.

Why Choose the HKM-2761939
Six reasons the HKM-2761939 keeps finding new homes.
Power That Matches the Rider
The 24V and 36V options mean nobody has to buy a bike a child will grow into next year. Choose calm now and lively later, and the frame, brake and wheels never change underneath the rider.
Charging That Fits Family Life
The drop-down pack comes to the bench for charging, so there is no garage socket visit and no bike parked by the wall overnight. A spare pack can wait indoors fully charged for back-to-back sessions.
Nothing to Service Weekly
A hub motor means no chain, no sprocket and no grease. The weekly routine is a wipe-down, a tyre-pressure glance and a brake squeeze, which takes less time than finding the helmet before a ride.
Braking Without Drama
The rear disc works the same on day one hundred as on day one, and its bite does not fade on wet grass the way a rim surface does. One lever keeps the controls count at exactly one job for a small hand.
Standard Parts Throughout
Forks, levers and fasteners follow bicycle conventions, so any local shop can service the bike. Wear items stay cheap and available, which matters once a young rider discovers what kerbs are for.
A Seat for Every Stage
The adjustable saddle keeps feet flat at three years old and keeps the bike honest toward eight. The 110 lbs load rating gives the frame room to stay useful through several growth spurts.
Frequently Asked Questions
Straight answers about the HKM-2761939.
Should I buy the 24V or 36V version?
The 24V pack keeps the pull gentle and suits a true beginner on flat ground, while the 36V pack gives the 250W motor more energy for longer sessions and gentle slopes. Both fit the same drop-down mount, use the same charger type and share every other part of the bike, so the decision is entirely about the rider rather than the machine. Both versions share the same drop-down mount and the same bench-charging routine, so nothing changes later.
What ages and sizes does it fit?
The bike suits riders from three to eight, and leg length is the honest measure: both feet should rest flat while seated. The adjustable saddle starts low enough for a confident three-year-old and climbs as the rider grows, with a 110 lbs load rating that keeps the same bike in service across several seasons of growth. Measure inside leg length before ordering to confirm the fit on day one.
How does the drop-down battery work day to day?
The pack seats in a mount under the frame and releases in one motion for indoor charging, then clicks back in until it latches. The routine suits families: charge at the kitchen bench, keep a spare pack indoors if sessions stack up, and never park the bike beside a socket overnight. A fully seated pack shows a small gap-free line around the mount edge.
What are the two speed modes for?
The modes change how eagerly the motor answers the throttle, not a hard speed cap. Gentle mode rolls in slowly, which suits a rider still connecting throttle with movement, while the livelier mode suits a child who rides with their eyes up. Start gentle for the first sessions and move up when steering and stopping need no reminders. Most riders move up within a fortnight of regular sessions.
Is the rear disc enough brake?
For this weight and speed, one rear disc is the right answer, not a compromise. It gives a small hand one lever and one predictable bite, and disc power does not fade on wet grass or shallow puddles the way a rim surface would. The habit the rider builds here transfers directly to the next, bigger bike. It also needs no cable route, which keeps the frame lines clean.
What upkeep does the bike need?
Very little, by design. Keep the knobby tires inflated to the pressure printed on the sidewall, wipe the frame and battery mount with a damp cloth rather than a hose, and test the rear brake before each session so a soft lever is caught at the barrel adjuster. That is the entire weekly list, and it keeps the bike ready for the whole season.
Quick Troubleshooting
When the HKM-2761939 acts up, work through these in order.
The bike will not power on
Lift the pack from its drop-down mount and seat it back until it latches, because a pack resting one click short of home makes no contact. Press the power button and watch the indicator. If it stays dark, charge for half an hour and retry, check the mount contacts for grit, and confirm the wall socket works with another device before anything else. A spare pack that also shows dark confirms the fault is in the bike, not the pack.
The brake lever reaches the grip
Take up slack at the barrel adjuster on the lever a turn at a time, then check the cable anchor at the calliper. A rotor touched by oily fingers will glaze and lose bite, so clean it with isopropyl alcohol and replace any pads that have soaked through. Bedding-in needs a dozen gentle stops before the bite reaches full strength. Worn pads past their indicator line need replacement rather than more adjuster turns.
The battery refuses to charge
Watch the charger indicator when the pack connects, and make sure both connectors seat fully with nothing in the ports. Dust in the charge port is the quietest cause and the easiest fix with a dry cloth. A cold pack will refuse a fast charge until it warms to room temperature, and a steady fault light after a short rest means the pack needs testing. Try a second charger if one is available, since chargers fail more often than packs.
Run time keeps getting shorter
Compare like with like first: full-throttle starts and grass climbing use far more per minute than steady cruising, and a 2.5Ah-class pack does roughly half the distance of a larger one. Soft tires cost range twice, in drag and in speed. If riding habits have not changed, run one full uninterrupted charge cycle and retest before judging the pack. Range also drops in cold weather, which is normal for every lithium pack.
The throttle feels uneven
A pack running low makes the motor surge under load, so start with a full charge on gentle mode. Then check the throttle connector for a half-seated plug and keep the grip area clean, because dust under the cap causes the same feel. If surging continues with a full pack, note when it happens and contact support about the controller. Swap modes once to confirm the switch itself is making contact properly.
The wheel wobbles or pulls
Lift the front and spin the wheel to see whether the wobble is in the wheel or the fork mount. Check both axle nuts first, because transport knocks loosen them, and confirm the tire has not crept off centre. If the pull continues with everything tight, have the fork alignment checked at a shop before the next outdoor session. A deflated tire on one side can also imitate a pull, so check pressures first.

Important Safety Notes
Read these notes before the first ride on the HKM-2761939.
The HKM-2761939 is a powered bike for riders aged three to eight, so an adult stays within arm’s reach on every ride. A certified helmet goes on before the first throttle press, with closed shoes and a clear, flat riding area making the early sessions easier. Begin in gentle speed mode and let the rider learn the throttle at walking pace before any real speed, keeping sessions short while the braking habit forms. Check that the battery is fully latched before each ride, keep fingers and loose clothing clear of the rear hub while the wheel turns, and never carry a passenger on the frame or the saddle. Charge the pack indoors at room temperature on a hard surface, unplug once the indicator shows full, and test the brake, the tires and both axle nuts before every outing.
