Overview
The HKM-710419 is built on an aluminum alloy dirt-bike frame with a low seat and a confident, upright riding position suited to riders 13 and older. The frame is rated for a rider-and-gear load of approximately 220 lb, and the compact 14 in-wheel platform keeps the bike manageable for smaller riders while still being serious off-road equipment.
A 48 V 2000 W brushless rear hub motor delivers strong, controllable low-end torque for climbs and quick acceleration off the line. The motor is fed by a 48 V 21 Ah lithium pack that stores 1008 Wh - enough for a long session on the trails between charges. A twist throttle with 3 speed modes lets a newer rider start gentle and step up as skill grows.
Real-world range runs 19-37 mi (31-60 km) because the bike adapts to how you ride it. Easy trail cruising in the lower speed mode returns the upper end of that band; full-throttle running in the top mode lands nearer the lower end. Cold weather, heavy riders, soft terrain, and steep climbs all reduce range; firm terrain and milder weather push it back up.
Suspension and brakes are sized for real off-road use. A front suspension fork and a rear shock absorb jumps, roots, and chop, while 14 in all-terrain tires put the power down on dirt, grass, and hardpack. Hydraulic disc brakes at both ends provide strong, consistent stopping power, and the LCD shows speed, battery, mode, and trip distance.
Key Features
48 V 2000 W Brushless Rear Hub Motor
A 2000 W brushless motor is laced directly into the rear wheel hub and runs on a 48 V system for strong, controllable low-end torque. There is no mid-drive gearbox or extra chain in the drive path, so drive losses stay low and maintenance is limited to keeping the axle nuts torqued. The motor climbs steep grades and pulls away confidently from a stop.
48 V 21 Ah Lithium Pack (1008 Wh)
The pack lifts out for indoor charging and stores 1008 Wh of energy for long trail sessions. A full recharge from empty takes about 3-4 hours on the supplied fast charger; partial top-ups take proportionally less. Two keys are included to lock the pack in place.
Front Fork + Rear Shock
A front suspension fork and a rear shock work together to absorb jumps, roots, and trail chop that a rigid frame would transmit straight to the rider. The combination keeps both wheels planted for grip and control on rough ground.
Hydraulic Disc Brakes, Front and Rear
Sealed hydraulic lines actuate both calipers. Lever effort stays light and predictable when the rotors get hot, and there are no cables to stretch or corrode. Power-off brake levers cut motor drive the instant either lever is pulled - important on a 31 mph dirt bike.
3-Speed Twist-and-Go Drive
A twist throttle selects among 3 speed modes with no derailleur or gear shifting to manage - twist and go. Start in the gentle mode to build confidence, then step up to the faster modes as skill grows. The single-speed chain keeps the driveline simple to service.
14 in All-Terrain Dirt Tires
The knobby 14 in tires dig into dirt, grass, and hardpack for grip and control where a street tire would spin. The compact wheel size keeps the bike light-handling and easy for younger riders to manage.
LED Headlight and Integrated Brake Light
A bright LED headlight runs off the main pack so there are no separate batteries to keep charged. A brake light that illuminates whenever either brake lever is pulled adds visibility - useful in dusk or low light.
Folding Footpegs and Side Stand
Folding footpegs tuck up out of the way for transport and storage, and a side stand holds the bike upright for charging and quick stops. The low seat and peg position keep a younger rider balanced and in control.

Battery, Range, and Charging
The 48 V 21 Ah pack stores 1008 Wh of energy - among the largest in its class, which is what delivers 19-37 mi (31-60 km) of trail running per charge. That headroom lets a rider spend a long session on the trails without watching the gauge.
Real-world range depends on the speed mode, rider weight, terrain, and tire pressure. Gentle cruising in the lower mode lands near the top of the range; full-throttle running in the top mode lands near the bottom. Cold weather below 40 F (4 C) temporarily reduces available capacity by 10-20 percent; it returns once the pack warms up.
Tip: Store the pack between 30 and 70 percent charge if the bike will sit unused for more than a month, and top it up every 4-6 weeks. Charging indoors at room temperature extends usable pack life considerably compared with charging in an unheated garage.
The pack lifts out for indoor charging and locks in place with the supplied key. Two keys are included. Charging with the pack installed works equally well - the charge port is accessible without removing anything.
Daily Use & Care
- Check tire pressure and set it for the surface: lower pressure on loose dirt for grip, higher on hardpack to reduce pinch flats.
- Rinse the frame, wheels, and driveline with fresh water after riding in mud or dust. Abrasive grit attacks fasteners and the chain if left in place.
- Check that both axle nuts and the stem bolts are torqued before each ride. Hub-motor torque works fasteners loose faster than on a conventional bicycle.
- Wipe and re-lubricate the drive chain every 50-100 mi, or after any ride through mud or dusty conditions.
- Inspect brake pad thickness monthly. Hydraulic pads wear silently until they are gone; replace when the friction material is under 1 mm.
- Charge indoors at room temperature. Unplug the charger once the indicator turns green rather than leaving it connected for days.
- Keep the display and charge port covers closed when the bike is parked outside so moisture stays out of the connectors.

Frequently Asked Questions
What age rider is this dirt bike suited to?+
The HKM-710419 is rated for riders 13 and older. The 3 speed modes let a newer or younger rider start in a gentle mode and step up as confidence and skill grow. Adult supervision is recommended for younger riders, and all riders should wear proper protective gear.
How much assembly is required out of the box?+
The bike ships approximately 85 percent assembled. Remaining steps are fitting the front wheel, straightening and bolting the handlebar, and checking brake alignment. Budget 30-45 minutes with the supplied tools. Have a shop check torque and brake bedding if you are not comfortable doing it yourself.
What is the actual range I should plan for?+
Plan for 19-37 mi (31-60 km). Gentle cruising in the lower speed mode reaches the top of that band; full-throttle running in the top mode lands near the bottom. Heavier riders, hills, and soft terrain all reduce range.
How long does the battery take to charge?+
About 3-4 hours from fully empty with the supplied fast charger. Partial top-ups take proportionally less time; there is no need to run the pack down before recharging.
Is a license or registration required?+
Rules vary by state and locality, and by where you ride. A 2000 W motor with a 31 mph top speed is well outside the common three-class e-bike framework and is intended for private property and designated off-road areas. Check your state DMV and local ordinances before riding on public roads or bike paths.
Can it be ridden if the battery runs out?+
The bike is driven solely by the motor, so it cannot be pedaled home like a bicycle. Plan rides within range and carry the charger for longer trail days.
Is the battery removable for indoor charging?+
Yes. It lifts out for indoor charging and locks in place with the supplied key. You can also charge it in place through the frame-side charge port.

Why Choose the HKM-710419
Built for Off-Road Fun
A 2000 W hub motor, real suspension, and knobby 14 in tires make this a genuine dirt bike for private property and designated off-road trails - not a stripped-down commuter. It is sized and tuned for riders 13 and older.
Front and Rear Suspension
Jumps, roots, and trail chop become rideable when the front fork and rear shock absorb what a rigid frame would transmit directly to the rider. The suspension keeps both wheels planted for grip and control.
Three Speed Modes
A twist throttle selects among 3 speed modes with no shifting to manage. Start gentle to build confidence, then step up as skill grows. The single-speed chain keeps the driveline simple.
Quiet Electric Drive
The hub motor is quiet compared with a gasoline engine, so you can ride without the noise and fumes - and with far less maintenance than a small combustion motor.
Manageable Size for Younger Riders
The compact 14 in-wheel platform and low seat keep the bike light-handling and easy for smaller riders to manage, while the aluminum frame stays sturdy off-road.
Built for the Elements
Sealed electrical connectors, a covered and lockable battery compartment, and hydraulic brake lines that resist corrosion all make sense for a bike that gets ridden through mud, dust, and weather.

Pre-Ride Safety Checklist
- Check tire pressure and set it for the surface: lower on loose dirt for grip, higher on hardpack.
- Squeeze both brake levers. They should firm up well before reaching the grip, with no sponginess that would indicate air in the hydraulic line.
- Confirm the battery is seated and locked, and that the display shows the expected state of charge.
- Spin both wheels and check that the rims run true and nothing rubs the brake pads or the frame.
- Verify the axle nuts and stem bolts are tight, and that the headset has no play when you rock the bike with the front brake applied.
- Test the throttle at walking pace in a clear area before riding at speed or with a younger rider.
- Switch on the headlight if you will be riding near dusk, and wear a helmet and protective gear rated for off-road use.
- If a younger rider is mounting, confirm the footpegs are deployed and the speed mode is set to the gentle setting.
Quick Troubleshooting
The motor does not engage when I twist the throttle.+
Confirm the display is on and shows charge, the battery is locked into place, and both brake levers are fully released - brake cut-off sensors disable the motor while a lever is pulled. If the display shows an error code, note it and contact support.
Range dropped noticeably compared with when it was new.+
First check tire pressure; a soft tire is the most common cause. Then consider temperature - cold reduces available capacity temporarily. If range is down more than 30 percent year-round after many charge cycles, the pack may be approaching the end of its service life.
The brakes feel spongy at the lever.+
Sponginess in a hydraulic system usually means air in the line or a fluid leak. Stop riding and have the system bled and inspected. Do not continue riding a 31 mph bike on compromised brakes.
The chain skips or jumps under hard acceleration.+
The chain tension is likely out of adjustment, or the chain and rear sprocket are worn. Adjust tension a quarter turn at a time to align the driveline. If it skips only under load, the sprocket is worn and should be replaced along with the chain.
The front fork or rear shock feels harsh or bottoms out.+
Check that the wheels are seated in the dropouts and the suspension is set as intended for the rider weight. If the harshness persists, the suspension may need service - have a shop inspect the seals and rebuild if needed.
The display shows an error code and the bike will not move.+
Power the system off, wait 30 seconds, and switch it back on. If the code returns, note the exact code and the conditions that produced it, then contact support - error codes map to specific faults in the controller, motor, or throttle circuits.

Important Safety Notes
This is a high-output electric dirt bike capable of 31 mph. It is intended for private property and designated off-road areas, not public roads. Read the manual fully before the first ride and practice throttle control in an open area until the response feels predictable. Riders should be 13 or older; younger riders need adult supervision.
- Always wear a helmet and protective gear (gloves, boots, knee and elbow protection) rated for off-road motorcycling.
- Do not exceed the approximately 220 lb (100 kg) rider-and-gear load.
- Ride only on private property or designated off-road areas. A 2000 W motor with a 31 mph top speed is outside standard e-bike classifications and is not for public roads or bike paths without specific local authorization.
- Bed in the brake pads with 10-15 progressive stops during the first few rides before riding at full speed.
- Do not ride through water deep enough to reach the hub motor or the battery compartment.
- Charge only with the supplied charger, indoors, at room temperature, and on a non-flammable surface. Do not leave a charging battery unattended overnight.
- Do not attempt to open, puncture, or modify the battery pack. Damaged lithium packs can vent and ignite.
- Start younger or newer riders in the gentle speed mode and step up only as skill grows.
