HKM-3318995 20-Inch Electric Balance Bike for Young Riders with 800W Brushless Motor, 3-Speed Gears and Hydraulic Disc Brakes
HKM-3318995
The Pro Cross: 800W on 20-Inch Wheels
The HKM-3318995 is the FXB01-20 Pro Cross, a 20-inch electric balance bike that takes the platform up a class. An 800W brushless rear hub motor drives three speed gears, hydraulic disc brakes bring smooth, controlled deceleration, and the 36V lithium battery charges in 1 to 1.5 hours for 15 to 20 km of range. The aluminium alloy frame keeps the build light, the LED display shows speed and battery at a glance, and Kenda K1237 tires hold traction from city pathways to green trails with an 80 kg load rating behind it all.
Key Features
Six details that define the Pro Cross.
800W Brushless Rear Hub
The 800W brushless motor lives in the rear hub and delivers consistent, efficient power that makes uphill climbs and long rides noticeably easier. There is no chain to oil or tension, and the pull stays smooth from a standstill through every gear.
Three Speed Gears
The 3-speed gears let young riders match the pace to the path and the confidence level, from calm first laps to quicker open-ground running. The range of pace is the feature: the bike meets the rider where they are on the day.
Hydraulic Disc Brakes
The hydraulic disc brake system provides smooth, safe deceleration with a bite that builds progressively under one finger. It is the brake technology adult bikes take for granted, built into a bike young riders can learn on properly.
36V Battery, Fast Charge
The 36V lithium battery covers 15 to 20 km per charge and refills in just 1 to 1.5 hours, so a forgotten charge rarely costs a full session. Plug in at the wall after lunch and the afternoon is back on.
LED Display On Board
The LED display puts speed and battery life in the rider's eyeline, which turns power management into a habit instead of a surprise. Knowing what is left in the pack is the first step toward planning a route home.
Kenda Tires, 80 kg Rating
Sturdy Kenda K1237 tires hold traction on varied surfaces, the adjustable seat tracks the growth, and the 80 kg load rating opens the bike to a broad age range. The aluminium alloy frame ties it together with lightness and strength.
Overview
A 20-inch balance bike with 800W power, 3-speed gears, hydraulic disc brakes and an LED display.
The HKM-3318995 is the FXB01-20 Pro Cross, a 20-inch electric balance bike built for riders ready for more bike underneath them. An 800W brushless rear hub motor drives three speed gears, hydraulic disc brakes deliver smooth, controlled deceleration, and the 36V lithium battery charges in 1 to 1.5 hours for 15 to 20 km of range. The LED display keeps speed and battery in view, Kenda K1237 tires hold traction across varied terrain, and the adjustable seat and aluminium alloy frame carry riders up to 80 kg through the years. It is the Pro Cross take on the platform: more power, more control, and the same honest build.
Hydraulics at One Finger
Stopping power that builds, never grabs.
Hydraulic disc brakes build the bite progressively, so one finger controls deceleration the way adult bikes do. On the Pro Cross it means smooth, safe stops from every gear, on every surface.

Everything worth knowing, in one table.
Why a Display Belongs on a Kids Bike
What the rider can see, the rider can plan.
Most kids' bikes hide the battery, and that is exactly how rides end in pushes home. The Pro Cross puts an LED display on the bars instead, showing speed and remaining charge at a glance, so the rider learns to budget power the way they will on every bike after this one. It turns the ride home into part of the route plan rather than an emergency. Around the display runs an 800W brushless rear hub with three speed gears, hydraulic disc brakes that decelerate smoothly, and a 36V pack that refills in 1 to 1.5 hours. Kenda K1237 tires hold the traction, the aluminium alloy frame keeps the weight honest, and the 80 kg load rating spans the years of use.

Why Choose the HKM-3318995
Six reasons families pick the HKM-3318995.
Power With a Purpose
The 800W brushless hub makes climbs and long rides easier without ever feeling spiky, and the three gears keep the pace matched to the rider. Power serves the lesson instead of replacing it.
Brakes That Build Trust
Hydraulic disc brakes decelerate smoothly 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.
A Display That Teaches
The LED readout of speed and battery turns power management into a habit. Riders who can see the charge plan their routes, and planned routes end at home, not in a push.
Charging That Fits Real Life
The 36V pack refills in 1 to 1.5 hours and covers 15 to 20 km, so a forgotten charge rarely ruins a session. Lunch is long enough to restore the afternoon.
Tires That Hold the Line
Kenda K1237 tires are chosen for traction and control across city pathways and green trails alike. The grip is the quiet feature that makes the power usable.
Built for Broad Ages
The adjustable seat, 20-inch wheels and 80 kg load rating open the Pro Cross to a wide range of riders and years of use. Siblings can share what does not wear out.
Frequently Asked Questions
Straight answers about the HKM-3318995.
What ages and heights does the HKM-3318995 fit?
The Pro Cross suits a broad age range thanks to 20-inch wheels, an adjustable seat and an 80 kg load rating. The honest check is both feet flat while seated with knees slightly bent and hands reaching the bars at comfortable extension. Because this bike carries 800W and hydraulic brakes, confirm the rider can work the brake lever with one finger before moving up through the gears.
How do the three speed gears work?
The 3-speed gears pace the bike through the 800W brushless rear hub, from a calm first gear for learning laps to quicker settings for open ground. Move up one gear at a time on flat, open ground with clear sight lines, and only when the throttle and the hydraulic brake lever are under smooth one-finger control. The pace should always match the skills behind it.
How far does it go and how fast does it charge?
A full charge covers 15 to 20 km, which is a solid session of pathways and park loops. The 36V lithium battery refills in 1 to 1.5 hours at any wall socket, one of the shorter charge times in the range. Charge indoors at room temperature on a hard surface, unplug once the indicator shows full, and bring the pack inside on cold days before judging its charge.
What does the LED display show?
The LED display shows speed and remaining battery life in the rider's eyeline. That turns power management into a habit: riders learn to watch the charge, budget the distance and plan the ride home before the pack runs low. Teach the one-third rule early - when the display shows a third left, turn for home. It is the first step toward the range planning every later e-bike will ask for.
What maintenance do hydraulic brakes need?
Very little. The system is sealed, so there is nothing to lubricate, and pad wear at this power level is slow. Check the lever feel weekly: a bite well before half travel means all is well, a spongy lever means air in the line and a visit to support. Keep the rotors clean with isopropyl alcohol after muddy rides, because a firm lever with a clean rotor is the healthy baseline.
What assembly and upkeep are involved?
Assembly covers the handlebar, seat height, display 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.
Quick Troubleshooting
When the HKM-3318995 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 bike indoors before judging a winter battery.
The range keeps shrinking
Compare riding style before blaming the pack, because hills and the top gear use far more per kilometre than cruising in first. 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, and log the loop you retest on before replacing anything.
The brake lever feels spongy
A spongy hydraulic lever means air in the line, not a worn pad, and bleeding the system is a job for support or a shop. First confirm the lever still bites and the rotor is clean, then contact support with a note of when the feel changed. Spongy levers are a support job, not a trailside fix, so stay off steep terrain until the firm bite returns.
The LED display shows nothing
Check the display connector first, because a plug half-seated during transport is the most common cause. With the connector seated and the pack charged, power on and watch for the backlight. If the display stays dark on a charged bike, note whether the motor still runs and contact support with that detail, because it separates a display fault from a controller fault.
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.
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 gear selector has not been nudged. If cutouts continue on flat ground in first gear with a full, cool pack, note the gear in use and contact support. Log when it happens: climbs point to the pack, flat-ground cutouts point to the controller.

Important Safety Notes
Read these notes before the first ride on the HKM-3318995.
The HKM-3318995 is a high-power 20-inch balance bike with an 800W motor and hydraulic braking, so a certified helmet is mandatory before every ride, with closed shoes and snug laces completing the kit. Start in first gear on flat, open ground until the rider has the brake lever and the throttle under smooth one-finger control, with an adult approving every gear change. Confirm the battery is fully latched 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 rotors 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.
