A suspension fork and dual rear coil springs soak up the broken ground, and a Shimano seven-speed drivetrain with a twist-grip throttle keeps the ride flexible. Rated up to 70 miles per charge and a 31 mph top speed, with turn signals, an electronic horn and an LCD on the bars.\u003c\/p\u003e\n\n\u003cp\u003eThe format is a mini moped with pedals: a long banana seat, tall bars, a round LED headlight up front and a tank box sitting in the frame between your knees. That tank box is the 25Ah pack, lockable and liftable, and it is where the up to 70 mile claim comes from. The two hub motors split the work between the wheels, and the switch on the bars runs the rear alone on dry pavement or both hubs together when the ground turns soft.\u003c\/p\u003e\n\n\u003cp\u003eThe trade is attention. A dual-motor bike with fat tires is quick and thirsty under hard throttle, and 31 mph wants a helmet and a look at local rules before it mixes with traffic. Keep the pack charged and the chain clean, and it is a dependable runabout for city streets, gravel paths and sandy lots alike.\u003c\/p\u003e\n\n\u003ch2\u003eAt a Glance\u003c\/h2\u003e\n\n\u003cul class=\"hkm-glance\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e2000W Dual Motors\u003c\/strong\u003e — A hub in each wheel, brushless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1200Wh Tank Pack\u003c\/strong\u003e — 48V 25Ah, removable and lockable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUp to 70 Miles\u003c\/strong\u003e — Maker max figure per charge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e31 mph Top Speed\u003c\/strong\u003e — 50 km\/h as listed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Dual Switch\u003c\/strong\u003e — Rear only or both hubs, your call\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydraulic Discs\u003c\/strong\u003e — Red calipers front and rear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Coil Rear\u003c\/strong\u003e — Suspension fork up front too\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e20 x 4.0 Fat Tires\u003c\/strong\u003e — Knobby casings for loose ground\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShimano 7 Speed\u003c\/strong\u003e — Thumb shifter plus twist throttle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLCD Display\u003c\/strong\u003e — Speed, battery and assist level\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTurn Signals and Horn\u003c\/strong\u003e — Street lighting front and rear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e330 lb Load Rating\u003c\/strong\u003e — 150 kg platform rating\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat the Second Motor Changes\u003c\/h2\u003e\n\n\u003cp\u003eTwo hub motors change the character of a fat tire bike. Driving the front wheel as well as the rear keeps the bike straight in sand, wet grass and loose gravel, where a rear-only machine breaks the back tire free and steps sideways under power. Traction is what the second motor buys.\u003c\/p\u003e\n\n\u003cp\u003eIt also splits the load. Two motor shells shedding heat are less likely to end a long climb smelling hot than one shell doing everything, and each controller sees less current. On a bike built for 31 mph that margin is the one that matters.\u003c\/p\u003e\n\n\u003cp\u003eThe switch on the bars selects single or dual drive. Run the rear hub alone for dry pavement and better range, or bring the front in when the surface gets loose. It is a real control, not a badge, and it changes how the bike behaves.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eFront and rear hub motors\u003c\/li\u003e\n\u003cli\u003e2000W combined output\u003c\/li\u003e\n\u003cli\u003eSingle or dual motor switch\u003c\/li\u003e\n\u003cli\u003eBrushless drive with twist throttle\u003c\/li\u003e\n\u003cli\u003eTraction on sand, grass and gravel\u003c\/li\u003e\n\u003cli\u003eTwo shells share the heat load\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eFront drive does alter steering feel slightly under power, and the frame keeps that from becoming vagueness at speed. Two controllers mean more wiring to keep clean and dry, which is the honest cost of the layout.\u003c\/p\u003e\n\n\u003ch2\u003eThe Tank Pack and the Range Story\u003c\/h2\u003e\n\n\u003cp\u003eThe pack is 48V 25Ah, worth 1200Wh, and it lives in the tank box on the frame rather than hidden in a tube. The box locks with a key and lifts out, so the pack charges at a desk instead of next to the bike, and the maker also lets you charge it in place. A management system balances the cells and guards against overdraw and over-discharge, and the gauge on the pack shows what is left.\u003c\/p\u003e\n\n\u003cp\u003eWe quote up to 70 miles per charge, the maker figure for the 25Ah pack, which assumes a light rider on flat ground at low assist. Hard throttle, hills, cold weather and a full load all cut into it, sometimes by half, so treat 70 as an upper bound rather than a promise or a plan. Filling the pack from empty takes about six to seven hours on the included charger.\u003c\/p\u003e\n\n\u003cp\u003eThe bars carry the working parts: an LCD with speed, battery level and assist setting, a Shimano thumb shifter for the seven gears, a twist-grip throttle, and the pad that runs the lights, the turn signals and the electronic horn. Everything the ride needs sits under the rider's hands. Acceleration is smooth from a standstill.\u003c\/p\u003e\n\n\n\n\u003ch2\u003eA Moped Frame for City and Trail\u003c\/h2\u003e\n\n\u003cp\u003eThe frame is a welded moped-style mini: banana seat, tall bars, and the tank box up top. A suspension fork works the front wheel and two coil springs sit under the seat, so broken pavement gets filtered instead of passed to the rider. Hydraulic discs at both ends park it from 31 mph.\u003c\/p\u003e\n\n\u003cp\u003eThe 20 x 4.0 knobby tires are the other half of the story, with a wide contact patch that floats over soft ground and a tread that bites into dirt and sand where a street tire would skate.

Charge indoors with the supplied charger, unplug when the light turns green, and store the pack around half charge if the bike will sit for a month.\u003c\/p\u003e\n\n\u003cp\u003eEach ride starts with a tire pressure check and a squeeze of both brake levers. Hydraulic pads want a look monthly, the seven-speed chain wants a wipe and a drop of lube, and the coil springs want their sag checked now and then. Keep the axle nuts tight, wipe the frame after wet rides, and never aim a pressure washer at the connectors or the charge port. A gritty chain eats range before the pack does.\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-9235283\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eDual motor fat tire electric dirt bike, 20 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotors\u003c\/td\u003e\n\u003ctd\u003eDual brushless hub motors, 2000W combined\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor control\u003c\/td\u003e\n\u003ctd\u003eSingle or dual motor switch on the bars\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery\u003c\/td\u003e\n\u003ctd\u003e48V 25Ah lithium, 1200Wh, removable tank pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003eUp to 70 mi (113 km) per charge, maker figure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTop speed\u003c\/td\u003e\n\u003ctd\u003e31 mph (50 km\/h)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCharge time\u003c\/td\u003e\n\u003ctd\u003eAbout 6 to 7 hours from empty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrakes\u003c\/td\u003e\n\u003ctd\u003eHydraulic disc, front and rear\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFront fork\u003c\/td\u003e\n\u003ctd\u003eSuspension fork over the 20 in wheel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRear suspension\u003c\/td\u003e\n\u003ctd\u003eDual coil springs under the seat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDrivetrain\u003c\/td\u003e\n\u003ctd\u003eShimano 7-speed derailleur\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThrottle\u003c\/td\u003e\n\u003ctd\u003eTwist-grip on the bars\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTires\u003c\/td\u003e\n\u003ctd\u003e20 x 4.0 fat, knobby\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003eLCD, speed, battery and assist level\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLighting\u003c\/td\u003e\n\u003ctd\u003eLED headlight, tail light, turn signals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHorn\u003c\/td\u003e\n\u003ctd\u003eElectronic, on the bars\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLoad capacity\u003c\/td\u003e\n\u003ctd\u003e330 lb (150 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColors\u003c\/td\u003e\n\u003ctd\u003eBlack, Green\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAssembly\u003c\/td\u003e\n\u003ctd\u003ePartially assembled on arrival\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\u003eWe quote up to 70 miles per charge, the maker figure from the 1200Wh pack.
