HKM-9675987
The 350W All-Rounder for Young Riders
The HKM-9675987 from Fish Extreme covers the whole learning curve with one bike: a low training mode at 15 km/h and a high mode up to 30 km/h, paced by a 350W rear hub motor. The integrated 5.0Ah battery delivers 15-20 km per charge, the disc brake answers every call with precise stopping power, and the aluminium alloy frame holds the whole package to 12.0 kg with the battery fitted. The adjustable 54 cm seat and 16-inch wheels keep the fit and the handling steady as the skills climb.
Key Features
Six details that define the HKM-9675987.
350W Rear Hub Motor
The 350W motor sits in the rear hub and reaches speeds under 30 km/h efficiently, delivering its power directly where the wheel meets the path. It is smooth, quiet assistance sized for young adventurers.
Two Speed Options
A low training mode cruises at 15 km/h while riders learn balance and brake control; the high mode opens up to 30 km/h for the confident. Children gain confidence as they learn, and the bike grows with them.
Integrated 5.0Ah Battery
The 5.0Ah pack is built into the frame and delivers 15-20 km of range on a single charge, enough for hours of outdoor enjoyment between top-ups. There is no separate battery to carry or forget.
Light and Compact
At 12.0 kg including the battery, kids can handle the bike themselves, whether starting out or taking breaks. The 1220x515x650 mm footprint is spacious yet compact for storage and transport.
Adjustable 54 cm Seat
The seat height adjusts to 54 cm and accommodates growth as children enjoy their rides. Set it for today, reset it after the next spurt, and the fit stays honest for seasons.
Disc Brake Precision
The reliable disc brake system delivers precise stopping power whenever needed, at either speed option. Precise brakes are what turn an adventurous rider into a controlled one.

The integrated 5.0Ah battery delivers 15-20 km per charge, the reliable disc brake provides precise stopping power whenever needed, and the durable aluminium alloy frame holds the weight to 12.0 kg with the battery fitted.

Full Specifications
Everything worth knowing, in one table.
Speed Options Are a Teaching Tool
The right ceiling at the right time.
A speed limit is not a restriction on a kids' bike; it is the curriculum. The HKM-9675987's low mode holds 15 km/h while riders learn what balance feels like under power, and the high mode up to 30 km/h only arrives once the disc brake and the throttle are under smooth control. That structure sits on a genuinely capable platform: a 350W rear hub motor that reaches its speeds efficiently, an integrated 5.0Ah battery delivering 15-20 km per charge, and an aluminium alloy frame at 12.0 kg with battery. The adjustable 54 cm seat tracks the growth, the 1220x515x650 mm footprint stores easily, and the 16-inch wheels keep every session stable and maneuverable.

Why Choose the HKM-9675987
Six reasons families pick the HKM-9675987.
A Ceiling for Every Stage
The two speed options make the bike useful for years: 15 km/h for the learning months, 30 km/h for the confident ones. Progress comes from the rider, not from outgrowing the machine.
Power That Suits the Job
The 350W rear hub motor reaches its speeds efficiently and delivers assistance right at the wheel. It is plenty for open running, without a single overwhelming moment for beginners.
Range for Real Sessions
The integrated 5.0Ah battery covers 15-20 km per charge, which translates to hours of outdoor enjoyment between top-ups. Ride, recharge, repeat, all without a separate pack to manage.
Light for Small Hands
At 12.0 kg with the battery fitted, kids can wheel the bike themselves and adults can lift it without drama. The durable aluminium alloy frame is where the longevity and the lightness both live.
A Fit That Adjusts
The 54 cm adjustable seat accommodates growth as children enjoy their rides, and the 16-inch wheels keep the geometry stable. One purchase covers seasons of riding.
Stopping With Precision
The reliable disc brake system delivers precise stopping power whenever needed. At either speed option, the rider learns that speed and control arrive together.
Frequently Asked Questions
Straight answers about the HKM-9675987.
What riders is the HKM-9675987 sized for?
The bike runs 16-inch wheels and an adjustable 54 cm seat, sized for young adventurers learning on their first electric balance bike. Judge fit physically rather than by age: both feet flat on the ground while seated, knees slightly bent, hands reaching the bars at comfortable extension. The 12.0 kg weight with battery also keeps the bike manageable while those first habits form.
How do the two speed options work?
The low training mode holds 15 km/h for learners, and the high mode reaches up to 30 km/h for confident riders. Start in low on flat, open ground until balance, throttle and the disc brake are all under smooth control, then step up on ground with clear sight lines. Adults should approve every change, and the pace should always suit the surface of the day.
How far does it go on a charge?
The integrated 5.0Ah battery delivers 15-20 km per charge, with actual range depending on the speed mode, terrain, rider weight and temperature. High mode and hills use the pack faster than cruising in low. Charge indoors at room temperature on a hard surface and unplug once the charge completes, and the pack will thank you with consistent range.
Is it easy to store and transport?
Yes: the bike measures 1220 x 515 x 650 mm, spacious enough to ride comfortably yet compact enough for a boot, a garage shelf or a hallway corner. At 12.0 kg with the battery fitted, it lifts without drama, and the integrated battery means there is no separate pack to carry when you travel. A soft spot away from the weather also protects the finish over winter, and a quick post-ride wipe keeps things looking new.
What terrain can it handle?
The 16-inch wheels are sized for stability and maneuverability across various terrains, from pavement to packed paths. The durable aluminium alloy frame handles daily use, and the disc brake provides precise stopping on the way down. Loose sand and deep gravel exceed what any bike in this class can do, so treat those as walk-around sections.
What assembly and upkeep are involved?
Setup covers the handlebar, the seat height and a charge check, with the supplied hex keys and manual. Beyond that: tire pressure weekly, a disc brake check before rides and a wipe-down after dusty ones. The drive lives in the rear hub, so there is no chain to oil or tension all season, and the whole routine fits a weekend morning.
Quick Troubleshooting
When the HKM-9675987 needs attention, start here.
The bike will not power on
Confirm the battery has charge, then check the power button and indicator with the bike on flat ground. If the indicator stays dark, connect the charger for twenty minutes and retry, and inspect the charge port and contacts for grit or moisture. If everything looks clean and the bike stays dead, note what happened before the failure and contact support rather than forcing repeated restarts.
The range keeps shrinking
Compare riding style first, because the 30 km/h mode and hills use far more per minute than cruising at 15 km/h. Check tire pressure, since soft tires cost range twice. Cold weather trims every lithium pack. If nothing has changed, run one full uninterrupted charge and retest the same loop on the same mode, and log the loop you retest on before replacing anything.
The brake feels weak
Start with the lever and cable: check for stretch, grit at the lever pivot and full free travel, then follow the manual for adjustment. Retest on flat ground at low speed before returning to the high mode. If the bite still feels weak with the cable set correctly, note when the feel changed and contact support, because stopping power is 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 the wall and the bike. Charge indoors at room temperature, because cold packs refuse a full cycle, and check the port for grit or bent pins. If the indicator still never completes, stop forcing cycles and contact support with a note of recent charging times. Do not leave a stalled charge unattended overnight.
The motor cut out mid-ride
A battery running low or hot will step back before it dies, so start with a full charge and a cool-down. Confirm the speed mode has not been nudged and the power connections are seated. If cutouts continue on flat ground in the low mode with a full, cool battery, note the mode in use and contact support. Climbs point to the pack; flat-ground cutouts point to the controller.
The bike will not reach 30 km/h
First confirm the speed option is actually in the high setting, because the most common cause is the bike still in the 15 km/h mode. Next check tire pressure, since soft tires cap real speed long before the motor does. A low battery also steps the pace back to protect itself. If the bike still tops out short in high mode with fresh tires and a full charge, note the numbers and contact support.

Important Safety Notes
Read these notes before the first ride on the HKM-9675987.
The HKM-9675987 is a 16-inch-wheel balance bike with a 30 km/h high mode, so a certified helmet is mandatory before every ride, with closed shoes completing the kit. Start in the 15 km/h low mode on flat, open ground until the rider has the brake and the throttle under smooth control, with an adult approving every change. Confirm the battery is charged and the power connections seated before each ride, test the disc brake for the bite, and check the axle and stem hardware for torque. Keep fingers, laces and loose clothing clear of the rear hub while powered, and let hot parts cool after sessions. Charge indoors at room temperature on a hard surface, unplug once full, and never carry a passenger.
