A coil fork and twin coil shocks under the bench make it full suspension, mechanical discs slow both wheels, and a Shimano seven-speed with a thumb shifter handles the gears. The frame is welded carbon steel, the pack is key-locked and removable, and the LCD runs five assist levels plus a walk mode.\u003c\/p\u003e\n\n\u003cp\u003eThe case for this bike is what it does not ask of you. One motor, one controller, one pack, cable discs and a thumb shifter: there is no app to pair and no menu tree to learn. A rider can understand the whole machine after ten minutes with the manual, and every part of it is the sort of hardware a local shop already stocks. That matters on a farm track or a fire road at dusk, where a bike that is merely predictable beats a bike that is clever.\u003c\/p\u003e\n\n\u003cp\u003eThe honest trade is weight and brake hardware. At 136.7 lb it wants a ramp or a second pair of hands to load, and mechanical discs are the modest part of the build. They stop predictably in the dry and adjust with a barrel nut, though they are not hydraulic feel. Choose this bike for simple repairs and payload rather than lever finesse.\u003c\/p\u003e\n\n\u003ch2\u003eAt a Glance\u003c\/h2\u003e\n\n\u003cul class=\"hkm-glance\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e1500W Rear Hub\u003c\/strong\u003e — 48V brushless hub in the rear wheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e864Wh Pack\u003c\/strong\u003e — 48V 18Ah, key-locked and removable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e20 to 37 Miles\u003c\/strong\u003e — Listed range per charge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Suspension\u003c\/strong\u003e — Coil fork and twin rear shocks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical Discs\u003c\/strong\u003e — Front and rear rotors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e7-Speed Gearing\u003c\/strong\u003e — Shimano indexed, thumb shifter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e20 x 4.0 Tires\u003c\/strong\u003e — Knobby casing on spoked wheels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarbon Steel Frame\u003c\/strong\u003e — Welded step-over loop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLCD Display\u003c\/strong\u003e — Five assist levels and walk mode\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e330 lb Payload\u003c\/strong\u003e — 150 kg rated, conservative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour Colors\u003c\/strong\u003e — Red, yellow, black and blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e136.7 lb Net\u003c\/strong\u003e — 62 kg before the rider\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat Stays Simple and Why It Helps\u003c\/h2\u003e\n\n\u003cp\u003eSimplicity here is structural. The battery sits in a key-locked case on the down tube with one charge port and one lock, the controller is a single box under the vented cover, and the wiring ends at a bar-mounted LCD. Nothing needs a firmware update to keep working.\u003c\/p\u003e\n\n\u003cp\u003eThat matters in the field. When something goes wrong on a ranch road, a bike with cable discs, a chain and a thumb shifter goes right with the hex keys in the box and parts a town shop already carries. There is no dealer tool and no firmware flash to wait on.\u003c\/p\u003e\n\n\u003cp\u003eThe carbon steel frame carries the same logic. It is a welded step-over loop, heavy on purpose, braced at the rear triangle where the twin coil shocks mount. Steel tolerates the pull of a 1500W hub without going brittle, and it welds cleanly if a tab ever cracks.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eFrame: welded carbon steel step-over\u003c\/li\u003e\n\u003cli\u003ePack: 48V 18Ah, 864Wh, key-locked\u003c\/li\u003e\n\u003cli\u003eMotor: 1500W brushless rear hub\u003c\/li\u003e\n\u003cli\u003eFork: coil with preload\u003c\/li\u003e\n\u003cli\u003eRear: twin coil shocks under the bench\u003c\/li\u003e\n\u003cli\u003eBrakes: mechanical disc, both wheels\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eFitted as shipped: the round LED headlight, a rear light, front and rear fenders, the bench saddle, a kickstand and platform pedals. The bars carry the throttle, the assist switch, the brake levers and the display.\u003c\/p\u003e\n\n\u003ch2\u003e1500W and 864Wh\u003c\/h2\u003e\n\n\u003cp\u003eThe motor is a 1500W brushless hub in the rear wheel, which is the right size for a bike that weighs 136.7 lb before the rider. It pulls strongly from a standstill on gravel and holds speed up a long grade without the surge of an oversized controller, and the seven-speed cassette means the rider can pedal the bike home if the pack ever runs flat. The hub is sealed against water and the cable runs inside the chainstay, so a wet farm track does not faze it.\u003c\/p\u003e\n\n\u003cp\u003eThe pack is 48V 18Ah, worth 864Wh, in a key-locked case that lifts out for indoor charging. The listed range is 20 to 37 miles per charge: the wide end assumes pedal assist on firm ground and a light throttle hand, while throttle-only riding on soft dirt lands near the bottom. Charging from empty takes five to six hours on the included US-plug charger, so the routine is an overnight top-up rather than a lunch stop.\u003c\/p\u003e\n\n\u003cp\u003eFive assist levels and a walk mode live on the LCD, so the bike can be tuned to a work loop rather than one fixed feel. Walk mode earns its keep at 136.7 lb when a gate or a slope needs the bike pushed rather than ridden, and the throttle is there for the moments when pedaling a heavy bike through soft ground would only spin the wheel.\u003c\/p\u003e\n\n\n\n\u003ch2\u003eWhere It Fits and How It Rides\u003c\/h2\u003e\n\n\u003cp\u003eTwenty-inch 4.0 knobbies at low pressure carry the bike over gravel, roots and rutted farm track, and the coil fork plus twin rear shocks keep the bench level when the ground does not. On pavement the knobs hum and the steering slows down, which is the price of the tire rather than a fault.\u003c\/p\u003e\n\n\u003cp\u003eWhat it is not: a light trail bike, a stair-climber or a roof-rack job. Riders from about 5 ft 4 in to 6 ft 3 in fit the bench, and the 330 lb rating covers a grown rider with tools or a dog in a crate behind the seat.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eFarm tracks and private lanes\u003c\/li\u003e\n\u003cli\u003eFire roads and OHV areas\u003c\/li\u003e\n\u003cli\u003eRiders who value simple repairs\u003c\/li\u003e\n\u003cli\u003eNot for stairs or a roof rack\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\n\n\u003cdiv class=\"hkm-tablewrap\"\u003e\n\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eBike\u003c\/td\u003e\n\u003ctd\u003eAssembled frame, 1500W hub motor, 48V 18Ah pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery\u003c\/td\u003e\n\u003ctd\u003e48V 18Ah, 864Wh, key-locked and removable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCharger\u003c\/td\u003e\n\u003ctd\u003e48V US-plug charger, five to six hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTools\u003c\/td\u003e\n\u003ctd\u003eHex keys and a spanner for the axles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKeys\u003c\/td\u003e\n\u003ctd\u003eBattery keys for the pack case\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePedals\u003c\/td\u003e\n\u003ctd\u003ePlatform pair, left side reverse-threaded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFenders\u003c\/td\u003e\n\u003ctd\u003eFront and rear, fitted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight\u003c\/td\u003e\n\u003ctd\u003eRound LED headlight with a rear light\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManual\u003c\/td\u003e\n\u003ctd\u003eAssembly guide and quick-start card\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStand\u003c\/td\u003e\n\u003ctd\u003eSide stand, frame mounted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003c\/div\u003e\n\n\u003cp class=\"hkm-note\"\u003eBefore the first ride: fit the pedals, set the bars square to the fork, torque both axles, set the fork preload for your weight, bed the mechanical discs in with ten firm stops and charge the pack to full.

Take it to full once a month to balance the cells, never charge it below freezing, and if the bike will sit for a few weeks leave the pack around half charge and top it up every month. Charge indoors on a hard surface away from flammables.\u003c\/p\u003e\n\n\u003cp\u003eBefore every ride, check tire pressure and squeeze both levers. Around 20 psi suits pavement and 8 to 12 psi suits soft ground. The mechanical pads wear faster than hydraulic ones on a 136.7 lb bike, so look at them every few rides and turn the barrel adjuster as the lever creeps in. Keep the chain oiled, check the axle nuts after the first 50 miles, and rinse the frame with a low-pressure hose.\u003c\/p\u003e\n\n\n\n\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\n\u003cdiv class=\"hkm-tablewrap\"\u003e\n\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eHKM-8148179\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eFat tire electric dirt bike, 20 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor\u003c\/td\u003e\n\u003ctd\u003e1500W brushless rear hub\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery\u003c\/td\u003e\n\u003ctd\u003e48V 18Ah lithium-ion, 864Wh\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery mount\u003c\/td\u003e\n\u003ctd\u003eDown tube case, key-locked, removable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e20 to 37 miles per charge, listed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTop speed\u003c\/td\u003e\n\u003ctd\u003e20 mph on throttle as configured\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrame\u003c\/td\u003e\n\u003ctd\u003eCarbon steel, welded step-over\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFork\u003c\/td\u003e\n\u003ctd\u003eCoil suspension with preload\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRear suspension\u003c\/td\u003e\n\u003ctd\u003eTwin coil shocks under the bench\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTires\u003c\/td\u003e\n\u003ctd\u003e20 x 4.0 in knobby\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrakes\u003c\/td\u003e\n\u003ctd\u003eMechanical disc, front and rear\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDrivetrain\u003c\/td\u003e\n\u003ctd\u003eShimano 7-speed, thumb shifter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003eLCD, speed, assist level, battery state\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAssist\u003c\/td\u003e\n\u003ctd\u003eFive levels plus throttle and walk mode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLighting\u003c\/td\u003e\n\u003ctd\u003eRound LED headlight, rear light\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePayload\u003c\/td\u003e\n\u003ctd\u003e150 kg \/ 330 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet weight\u003c\/td\u003e\n\u003ctd\u003e62 kg \/ 136.7 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBoxed weight\u003c\/td\u003e\n\u003ctd\u003e79.5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCarton\u003c\/td\u003e\n\u003ctd\u003e150 x 34 x 80 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCharge time\u003c\/td\u003e\n\u003ctd\u003eFive to six hours from empty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWaterproofing\u003c\/td\u003e\n\u003ctd\u003eIP54 wiring and connectors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColors\u003c\/td\u003e\n\u003ctd\u003eRed, yellow, black, blue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAssembly\u003c\/td\u003e\n\u003ctd\u003eAbout 85 percent pre-assembled\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdiv class=\"hkm-q\"\u003e\n\u003ch3\u003eHow far does it go on a charge?\u003c\/h3\u003e\n\u003cp\u003eThe listed range is 20 to 37 miles per charge from the 48V 18Ah pack.
