Eleven Inch Traction and Dual Shocks over Gravel and Broken GroundKnobby Grip Meets Full Travel Calm
The HKM-3899347 is the off-road machine of the line - a 1200W brushless hub in the rear wheel, 11-inch knobby vacuum tires at both ends, and a dual-shock chassis that keeps the deck quiet when the ground is not. A 48V 13Ah pack worth 624Wh feeds the motor, the maker rates the load at 331 pounds, and the build lands at 62 pounds net with a saddle and a storage box. The LCD dash pairs with a phone app and unlocks by NFC, so the control stays close on every trail day.
Eleven-inch tires are the whole argument for this scooter over a city machine. The knobby vacuum tread gives a contact patch that conforms to gravel, packed dirt and broken pavement, and the sidewall absorbs the first sharp edges before the suspension has to. Yellow arms swing at both wheels with a coil spring up front and a second shock under the saddle, so the deck stays level over every root and washboard. Front and rear disc brakes sit at the hubs, and an LED headlight rides the fork arm.
Numbers stay honest on this page. The 1200W hub is the US-version figure printed on the maker's own graphic, and the same image states a 55 km/h ceiling, about 34 mph. The 624Wh pack returns 19 to 25 miles per charge, so plan on 19 miles and treat the rest as margin. The 331-pound load rating covers a rider and a pack.

Frame, Motor and Deck
The 1200W brushless hub motor sits in the rear wheel and pulls the machine away from a standstill with a full load on the deck. The US-version figure on the maker's graphic is 1200W, and the acceleration curve stays progressive rather than violent, which is what loose surfaces ask fo
The 48V 13Ah lithium pack is worth 624Wh and lives under the deck plate - the figure this listing has always carried. It feeds the 1200W hub for 19 to 25 miles per charge depending on how hard the ground fights back. A full charge takes 6 to 8 hours on the stock charger.
The dual-shock setup stacks a coil spring at the front fork and a second shock under the saddle, and the maker's graphic names the layout. With the air volume in the 11-inch vacuum tires, the system filters washboard before the deck starts kicking.
- Motor: 1200W brushless hub, US version
- Battery: 48V 13Ah / 624Wh lithium
- Range: 19 to 25 mi (30 to 40 km)
- Tires: 11 in off-road vacuum knobby
- Suspension: Dual shock, front spring and rear spring
- Brakes: Front and rear disc
- Display: LCD with App Sync and NFC unlock
- Seat: Saddle with storage box
Front and rear disc brakes clamp at the hubs, and the LCD dash reads speed, battery and trip while it syncs to a phone app and unlocks by NFC. The stem folds at the yellow star knob, and a saddle with a storage box bolts over the rear wheel.
Battery, Range and Charging
The maker quotes 19 to 25 miles per charge on the 624Wh pack, and this page carries that band forward with the honest caveats. Knobby tread has more rolling resistance than a slick, and soft ground or a hard headwind pulls the number down toward the floor of the range, so the working plan is 19 miles with the remainder held as margin. A 331-pound rider and a loaded storage box move the needle in the same direction.
A full charge takes 6 to 8 hours on the standard charger. Top the pack up after a deep ride instead of running it flat, and the 624Wh cells keep their capacity longer than a pack that lives on the shelf at zero. The 48V 13Ah pack and the US-plug charger in the carton are the match the spec sheet calls for, so the routine stays simple: charge, ride, charge again.
The pack lives under the deck plate where the frame keeps it clear of rocks and ruts, and the 62-pound net weight is the trade the 624Wh figure demands. Charge before a ride rather than after one, keep the pack between about 20 and 90 percent for daily use, and store it near half full if the scooter sits for a month between trail days.
Who It Fits and How It Rides
The HKM-3899347 fits the adult rider who wants one machine for the farm track, the fire road and the gravel lane at the end of the pavement. The 331-pound load rating covers a rider and a pack, and the saddle with its storage box turns the deck into a sit-down platform when the route runs long.
It rides best on loose and broken ground where the 11-inch knobby tires earn their keep. The folding stem means a trunk still works for storage. Check local rules before road sections and wear a helmet on every ride.
- Farm tracks, fire roads and gravel lanes where the 11-inch tread conforms
- Broken pavement and washboard filtered by the dual-shock chassis
- Sit-down stretches on the saddle with the storage box behind
- Night rides on the LED headlight and the rear lighting
- Trunk transport with the stem folded at the yellow star knob

Before the first ride: match the parts against the list, bolt the saddle and storage box down, check the folding latch locks with a firm click, set the tire pressure on both knobby tires, and charge the 624Wh pack full. Keep the carton for a month in case anything has to come back to us.
Colors and Finish
Available in Black.
Yellow covers the swing arms, the fork guards and the stem graphics, and the frame, deck and cockpit run black under the matching saddle and storage box. The two-tone scheme is the one in the photos on this page, and the paint is the same finish that rides on the folding star knob.
The black deck plate takes the scuffs of off-road use in stride, and the yellow arms show their paint where the gravel sprays. The rear fender takes the mud.
Battery Care and Maintenance
Treat the 624Wh pack as the machine's heart. Charge it after deep rides instead of running flat, store it near half full when the scooter sits for weeks, and keep the charge between about 20 and 90 percent for daily use. A pack that is always left full loses capacity faster than one held at a working level.
The moving parts ask for a small routine: keep the folding latch clean and locked before every ride, check the disc pads every few rides on gravel use, watch the suspension bushings for play monthly, and set the tire pressure on both 11-inch knobby tires before every trail day - on off-road rubber it changes both grip and range. The tool kit in the carton covers the stem latch, the wheels and the saddle bolts.

Frequently Asked Questions
How much assembly is required?
Most of the machine arrives assembled. Open the box, bolt the saddle and storage box down, fit the handlebar at the stem latch, unfold the stem until the yellow star knob locks, set the tire pressure and charge the 624Wh pack full before the first trail day.
Are 11-inch off-road tires worth it?
Yes - the 11-inch knobby vacuum tires roll over ruts, drain covers and roots instead of dropping into them, and the sidewall absorbs the first edges before the dual shocks work. On gravel and packed dirt the difference over a small city wheel is the whole reason this machine exists.
How far does it go on one charge?
The maker quotes 19 to 25 miles on the 624Wh pack, and the knobby tread is part of why - rolling resistance on loose ground costs energy. Plan on 19 miles and keep the rest as margin; soft surfaces and a loaded storage box pull toward the floor of the range.
How fast does it go?
Earlier runs of this listing quoted 31 mph; the maker's US-version graphic states 55 km/h, which is about 34 mph, and that is the figure we show. Speed on this build is a private-land number - city and state caps often sit far lower - so check local rules before road sections.
How much weight can it carry?
331 pounds (150 kg), rider and pack together, the load rating this listing carries. The frame runs aluminum alloy where weight matters and carbon steel where the loads are highest, and the dual-shock chassis is built to the same rating. The saddle and storage box are covered by the same figure.
Does it work with a phone app?
Yes - the LCD dash syncs to a phone app and the machine unlocks by NFC, both shown on the maker's own graphic for this build. The dash itself reads speed, battery level and trip distance whether or not the phone is paired, and the NFC card lives on the stem.
