HKM-1838675 16-Inch Electric Balance Bike for Young Riders with 36V Lithium Battery, Dual Speed Modes and Aluminium Alloy Frame
HKM-1838675
The FXB02-16: Balance Before Pedals
The HKM-1838675 is a 16-inch no-pedal electric balance bike built on a lightweight aluminium alloy frame with a brushless rear hub motor delivering 30-50 Nm of torque. Dual speed modes pace the ride, and the 36V lithium battery - 5.0Ah as fitted, with a 2.5Ah option - sits low in the frame for balanced handling and charges in 1 to 3 hours for 10 to 30 km of range. The disc brake system brings controlled stops, and the 16-inch wheels keep the platform steady through the learning laps. It is the bike that teaches balance first and power second.
Key Features
Six details that define the HKM-1838675.
No Pedals, Pure Balance
The no-pedal design puts every ounce of attention on balance and steering, the two skills every later bicycle needs. Riders push, glide and brake at their own pace, so confidence arrives before speed does, and the transition to pedals later feels natural.
Brushless Rear Hub, 30-50 Nm
The brushless motor lives in the rear hub and delivers 30-50 Nm of torque, enough for smooth acceleration and gentle climbs with no chain to oil or tension. Power arrives in a linear way that keeps early rides calm and predictable.
Dual Speed Modes
Two speed settings give one bike two lives: a calm pace for the learning laps and a quicker setting for riders who have earned it. The switch stays under adult control, so the pace moves up when the skills do, not before.
36V Battery Low in the Frame
The 36V lithium pack sits low in the down tube, which keeps the centre of gravity where handling is best. It charges in 1 to 3 hours for 10 to 30 km of range, and it unclips for charging at any wall socket.
Disc Brakes, Real Stopping
The disc brake system gives reliable stopping power with a bite that modulates instead of grabbing. Young riders learn to feather a lever rather than fear it, the braking habit every later bike will thank them for keeping.
Aluminium Alloy Frame
The aluminium alloy frame keeps the weight down without giving up the strength young riders lean on, and it shrugs off the knocks of outdoor play. Sixteen-inch wheels underneath hold the platform steady through every stage of learning.
Overview
A 16-inch no-pedal balance bike with dual speed, disc brakes and a 36V battery.
The HKM-1838675 is a 16-inch electric balance bike that treats learning to ride as a progression rather than a leap. The no-pedal design puts balance and steering first, a brushless rear hub motor with 30-50 Nm of torque drives dual speed modes, and the disc brake system delivers controlled one-lever stops. The 36V lithium battery sits low in the frame for handling that feels planted, charges in 1 to 3 hours, and covers 10 to 30 km per charge. The aluminium alloy frame keeps the whole bike light enough for the riders it is built for, and the dual-speed switch keeps the pace under adult control until the rider earns it. It is a bike made to make the first powered season a confident one.
Balance First, Power Second
The no-pedal way to learn to ride.
Pedals can wait. On the HKM-1838675, riders push, glide and brake at their own pace, so balance and steering arrive before speed does. It is the skills-first way to learn, and the one that sticks.

Everything worth knowing, in one table.
Why the Battery Lives in the Frame
A low centre of gravity is a safety feature.
Where the battery sits decides how a balance bike feels, which is why the HKM-1838675 carries its 36V pack low in the down tube instead of high on the rack. A low centre of gravity keeps the bike upright and predictable when the throttle opens, so a wobble stays a wobble instead of becoming a spill. It also keeps the frame lines clean and the pack protected between the rider and the ground. Around that battery runs a brushless rear hub with 30-50 Nm of torque, dual speed modes under adult control, and a disc brake system that stops the bike the way adult bikes do. The aluminium alloy frame ties it together at a weight young riders can handle, and the pack unclips in seconds when the 1-to-3-hour charge is due.

Why Choose the HKM-1838675
Six reasons families pick the HKM-1838675.
Skills Before Speed
The no-pedal design makes balance and steering the whole lesson, which is exactly what every later bicycle needs. Riders who learn this way usually skip the training-wheel stage entirely.
A Pace for Every Lesson
Dual speed modes mean the bike is never too slow to teach or too quick to trust. The low mode carries the learning, the higher mode carries the reward, and the adults hold the switch.
Stable by Design
The 36V battery sits low in the down tube, so the centre of gravity stays where handling is best. The bike feels planted when the power arrives, and wobbles stay small.
Brakes That Build Trust
The disc brake system modulates instead of grabbing, so riders learn to feather a lever rather than fear it. That trust carries into every faster bike they ride later on.
No Chain, No Fuss
The brushless motor drives from the rear hub, so there is no chain to oil, tension or snag. The weekly walkaround covers tires, brakes and battery contacts and takes minutes.
Light Enough to Grow On
The aluminium alloy frame keeps the weight where young riders can handle it, and 16-inch wheels hold the platform steady. It is the bike they learn on and the one they remember.
Frequently Asked Questions
Straight answers about the HKM-1838675.
What ages and heights does the HKM-1838675 fit?
The FXB02-16 platform suits riders moving up from smaller balance bikes or starting powered riding directly, with 16-inch wheels and an aluminium alloy frame sized for young riders. The honest check is both feet flat while seated with knees slightly bent and hands reaching the bars at comfortable extension. Because this is a powered bike with dual speed modes, also confirm the rider can work the brake lever smoothly before any change of pace, and keep the speed switch under adult control for the first weeks.
How does a no-pedal balance bike work?
There are no pedals to find: riders sit, push with their feet, and lift once they glide. The motor adds assistance as confidence grows, and the brake lever teaches real stopping habits. This is the skills-first path to cycling, because balance and steering are the hard parts of riding and pedalling is the easy one. Most riders who learn on a balance bike transition to a pedal bicycle without ever needing training wheels.
How do the dual speed modes work?
Two speed settings pace the bike through the brushless rear hub, and the switch belongs to the adults. Start in the low mode on flat, open ground until the throttle and the brake lever are under smooth control, then move up on ground with clear sight lines. The step between modes is deliberately small, so it feels like progress rather than a shock, and the higher mode stays earned rather than assumed.
How far does it go and how fast does it charge?
A full charge covers 10 to 30 km depending on terrain, mode and rider, which is a solid session of neighbourhood laps. The 36V lithium pack sits in the down tube, unclips for charging, and refills in 1 to 3 hours at any wall socket. A 5.0Ah pack comes as fitted, with a 2.5Ah option available. Charge indoors at room temperature on a hard surface, and unplug once the indicator shows full.
What assembly and upkeep are involved?
Assembly covers the handlebar, saddle height and battery seating, with the supplied hex keys and the manual. Beyond that: tire pressure weekly, a brake squeeze test before rides and a wipe-down after dusty ones. The brushless drive lives in the rear hub, so there is no chain to oil or tension all season. The whole routine fits a weekend morning, and the manual walks through each step with the tools supplied in the box.
Why does battery position matter?
Weight low in the frame keeps the centre of gravity near the ground, which is what makes a bike feel stable when the power arrives. The HKM-1838675 carries its 36V pack in the down tube for exactly this reason: the bike stays upright and predictable through throttle changes, and the pack sits protected between the rider and the ground. Rack-mounted batteries do the opposite, which is why those bikes feel top-heavy in corners.
Quick Troubleshooting
When the HKM-1838675 needs attention, start here.
The bike will not power on
Unclip the pack and seat it back until the latch clicks, because a pack just short of home makes no contact. Press the power button and watch for the indicator. If it stays dark, charge for twenty minutes and retry, check the mount contacts for grit, and confirm the wall socket with another device first. Cold packs read empty until warmed, so bring the pack indoors before judging a winter battery, and make the click part of the pre-ride routine.
The range keeps shrinking
Compare riding style before blaming the pack, because hills and the higher mode use far more per kilometre than cruising. Check tire pressure, since soft tires cost range twice. Cold weather trims every lithium pack. If nothing has changed, run one full uninterrupted charge cycle and retest the same loop. Log the loop you retest on, because different routes make different numbers, and retest before replacing anything.
The brake lever feels soft
A soft lever usually means the cable has stretched or the pads have glazed, both of which are adjustments rather than failures. Check that the rotor is clean and true first, then follow the manual for cable tension. If the lever still reaches the bar with the cable set, note when the feel changed and contact support. Stay in the low mode until the firm bite returns, because brakes are the one system never to ride on a maybe.
The charger light never turns green
Confirm the wall socket with another device, then reseat the charger plug at both ends. Check the pack mount contacts for grit and charge indoors at room temperature, because cold packs refuse a full cycle. If the indicator still never completes, stop forcing cycles and contact support with a note of how long charging has taken recently. Do not leave a stalled pack on the charger unattended overnight while you wait to retest.
The motor cut out mid-ride
A pack running low or hot will step back before it dies, so start with a full charge and a cool-down. Check the throttle connector for a half-seated plug and confirm the mode switch has not been nudged. If cutouts continue on flat ground in the low mode with a full, cool pack, note the mode in use and contact support. Log when it happens: climbs point to the pack, flat-ground cutouts point to the controller.
The battery will not seat in the tube
Check the mount rails for grit or a pebble first, because the down tube opening collects debris exactly at pack height. Wipe the contacts with a dry cloth and reseat the pack straight until the latch clicks. If the pack still will not home, look for a bent rail or a swollen case and contact support rather than forcing it. A pack that needs force to seat is telling you something is wrong.

Important Safety Notes
Read these notes before the first ride on the HKM-1838675.
The HKM-1838675 is a powered 16-inch balance bike, so a certified helmet is mandatory before every ride, with closed shoes and snug laces completing the kit. Start in the low mode on flat ground until the rider has the brake lever and the throttle under smooth control, with an adult approving every change of pace. Confirm the battery is fully latched in the down tube before each ride, squeeze the lever to feel the bite, and check the axle hardware for torque. Keep fingers, laces and loose clothing clear of the rear hub and rotor while powered, and let hot parts cool after long sessions. Charge the 36V pack indoors at room temperature on a hard surface, unplug once the indicator shows full, and never carry a passenger.
