HKM-0801363 28 mph Fat Tire Electric Mountain Bike, 750 W Rear Hub Motor, 1500 W Peak, 48 V 15 Ah 720 Wh Battery
HKM-0801363
750 W 28 mph Fat Tire Electric Mountain Bike
The HKM-0801363 is a fat tire electric mountain bike built on a 6061 aluminum alloy, compact mountain geometry. Small wheels, full travel, and a hub motor with real low-speed grunt.
Key Features
8 details that make the HKM-0801363 a dependable ride.
750 W Bafang Brushless Rear Hub Motor
A 750 W brushless motor with a 1500 W peak rating is laced directly into the wheel hub. There is no secondary chain or belt in the drive path, so drive losses stay low and routine maintenance is limited to keeping the axle hardware torqued. Rated wheel torque is about 85 N.m, which is what pulls the bike away from a standing start on a gradient.
48 V 15 Ah Lithium Pack (720 Wh)
The pack is built from Samsung cells and lives behind a lockable cover, lifting out with a key so it can be charged indoors while the bike stays where it is. 720 Wh is what makes the 30-55 mi range figure possible. A full charge from empty takes about 6 hours on the supplied charger; partial top-ups take proportionally less and do the cells no harm.
Full Suspension: Lockable Hydraulic Front Fork Plus Rear coil-over Shock
Full suspension: lockable hydraulic front fork plus rear coil-over shock. Suspension is not a luxury on a bike this heavy - it is what keeps the tires loaded and steering when the surface stops being smooth, and it is the difference between arriving comfortable and arriving beaten up after an hour in the saddle.
Hydraulic Disc Brakes
Sealed hydraulic lines actuate the calipers, so lever effort stays light and predictable as the rotors heat up on a long descent and there are no cables to stretch or corrode. Power-off levers cut motor drive the instant either lever is pulled, which is a meaningful safety feature on a 28 mph machine weighing 68 lb.
7-Speed Shimano Derailleur
A 7-Speed Shimano derailleur gives usable pedalling cadence from walking pace up to the assist ceiling. The wide ratio spread is what lets a heavier rider contribute on a climb instead of leaving the whole job to the motor and the battery, and Shimano index shifting means each click lands in gear rather than needing to be trimmed.
20 x 4.0 in All-Terrain Tires by Chaoyang
The 20 x 4.0 in casing spreads the weight of bike and rider over a large contact patch, so the tire floats over loose gravel and packed sand instead of digging in. The knobby all-terrain tread pattern adds grip on wet pavement and light snow where a narrower road tire would skate. Pressure sets the character: firmer for pavement efficiency, softer for grip off road.
Backlit LCD with Full LED Lighting
A backlit lcd reports speed, battery state, assist level, trip distance, and odometer, and switches between mph and km/h in the settings menu. LED headlight and brake-activated tail-light both run off the main pack, so there are no separate batteries to keep charged and nothing to forget before a ride home in the dark.
Rack
A rear carrier and full-length fenders are fitted from the factory rather than sold as extras, which is what turns the bike into transport instead of a toy. Total rated load is 330 lb (150 kg) including the rider, so there is genuine headroom for panniers, a week of groceries, or a loaded backpack on the way home.
Overview
Built for the ride ahead.
The HKM-0801363 is a fat tire electric mountain bike built on a 6061 aluminum alloy, compact mountain geometry. Small wheels, full travel, and a hub motor with real low-speed grunt. The frame is rated for a combined rider-and-cargo load of 330 lb (150 kg), and the recommended rider height range is 5 ft 1 in to 6 ft 2 in. The 750 W Bafang rear hub motor is laced directly into the wheel, so there is no belt or secondary chain in the drive path and maintenance amounts to keeping the axle hardware torqued. Peak output is 1500 W and rated wheel torque is about 85 N.m. Energy comes from a 48 V 15 Ah pack of Samsung cells holding roughly 720 Wh. Real-world range is a band rather than a number because the bike adapts to how you ride it. Throttle-only riding at or near the 28 mph top speed lands near the bottom of the 30-55 mi window. Moderate assist on mixed surfaces sits in the middle.
Engineered Around the Details That Matter
The HKM-0801363 is engineered around the details that matter for everyday riding.
Every detail is chosen to make the ride smoother, safer, and more dependable, from the frame geometry to the final finish. The HKM-0801363 pairs a 750 W rear hub motor (1500 W peak), Bafang, 48 V 15 Ah lithium-ion (720 Wh), Samsung cells, removable and lockable, a range of 30-55 mi (48-88 km), varies with terrain, rider weight, and assist level, so it is built for real-world rides rather than showroom specs.
Full Specifications
Measurements are shown in US customary units first, with metric equivalents in parentheses.
Battery, Range, and Charging
Up to 30-55 mi (48-88 km) per charge.
The 48 V 15 Ah pack stores about 720 Wh of energy in Samsung cells. For context, a typical commuter e-bike ships with 400-600 Wh, so this pack runs in the upper half of that band. That headroom is what turns the 30-55 mi figure from a laboratory number into something you can plan a day around. Four variables move real-world range more than anything else: how much you pedal, total rider and cargo weight, tire pressure, and terrain. Throttle-only riding near the 28 mph top speed lands close to 30 mi. Moderate assist on mixed surfaces sits around 42 mi. Light assist with steady pedalling on level ground is what produces the 55 mi upper figure. Cold below 40 F (4 C) temporarily reduces available capacity by 10-20 percent; it returns once the pack warms up.
Daily Use & Care
A short routine keeps the ride quiet and the range where it should be.
Tire pressure sets the character of the machine. Run 10-20 psi on pavement for lower rolling resistance; drop toward the lower end for gravel and dirt so the casing can flatten and grip.
Rinse the frame, rims, and drivetrain with fresh water after riding on salted roads or wet gravel. Road film attacks fasteners and pivots if it is left in place.
Check that the axle hardware and the stem bolts are torqued before the first ride of each week. Hub-motor torque works fasteners loose faster than on a conventional bicycle.
Wipe and re-lubricate the chain every 100-150 mi, or after any ride through standing water or heavy dust.
Inspect brake pad thickness monthly. Pads wear silently until they are gone; replace when the friction material is under 1 mm.
Charge indoors at room temperature and unplug once the indicator turns green rather than leaving the charger connected for days.
Keep the display and charge-port covers closed when the machine is parked outside so moisture stays out of the connectors.
Check spoke tension after the first 50 mi and then every few months. A 20 in wheel carrying 330 lb of rated load loses tension faster than a light road wheel.

Why Choose the HKM-0801363
6 reasons it earns its place.
Specified Around One Job
Small wheels, full travel, and a hub motor with real low-speed grunt. Every major component - motor rating, pack size, tire width, brake type - was chosen to serve that use rather than to fill a spec sheet.
Chassis Matched to the Power
A 750 W drivetrain on a bicycle chassis is a mismatch. Full suspension: lockable hydraulic front fork plus rear coil-over shock and hydraulic disc brakes, front and rear are what let the 28 mph top speed be used rather than merely quoted, and they are the parts owners notice on every ride rather than only on the test ride.
Two Ways to Ride
Twist the throttle for immediate acceleration, or shift through the 7-Speed Shimano derailleur and pedal. Most owners mix the two - throttle to get moving from a stop, gears and legs to stretch the 30-55 mi range on the flat, and motor again for the hills.
Low-Maintenance Drive Path
A rear hub drive keeps the number of wearing parts low. There is no complicated drive path to service, and the motor runs quietly enough that you hear the tires on the road before you hear the drivetrain.
Cost per Mile Is Trivial
A full 720 Wh charge costs roughly 15 to 25 cents at typical US residential electricity rates, and it covers 30-55 mi. That is a fraction of what the same distance costs in a car, with no fuel stop, no parking charge, and no tailpipe emissions at the point of use.
Built for Repeat Use
Sealed electrical connectors, a lockable battery compartment, Samsung cells with roughly 800 usable charge cycles, and a 6061 aluminum alloy frame are the specifications that decide whether a bike is still working in year three. Consumable parts - pads, tires, chain, cables - are standard sizes available from any bike shop.
Every Component Chosen for Real-World Use
Every component of the HKM-0801363 is chosen for real-world use.
It is built to be ridden regularly, cleaned easily, and kept in top condition with routine care. The HKM-0801363 pairs a 750 W rear hub motor (1500 W peak), Bafang, 48 V 15 Ah lithium-ion (720 Wh), Samsung cells, removable and lockable, a range of 30-55 mi (48-88 km), varies with terrain, rider weight, and assist level, so it is built for real-world rides rather than showroom specs.

Frequently Asked Questions
Quick answers about the HKM-0801363.
How much assembly is required out of the box?
The machine ships approximately 85 percent assembled. What remains is fitting the front wheel, aligning and bolting the handlebar, installing the pedals and saddle, and checking brake alignment. Budget 30-45 minutes with the supplied tools. If you are not comfortable doing it yourself, have a bike shop check torque and bed the brake pads in.
What range should I actually plan for?
Plan for 30-55 mi depending on how you ride. Throttle-only near the 28 mph top speed lands close to 30 mi. Moderate assist on mixed terrain returns around 42 mi. Heavier riders, headwinds, hills, cold weather, and low tire pressure all reduce the figure.
How long does the battery take to charge?
About 6 hours from fully empty with the supplied charger. Partial top-ups take proportionally less time, and there is no need to run the pack down before recharging - lithium cells prefer shallow cycles.
Is a license or registration required?
Rules vary by state and locality. A 750 W nominal motor with a 1500 W peak and a 28 mph top speed exceeds the limits of the common three-class e-bike framework in many US jurisdictions, which may place this vehicle in a moped or motor-driven cycle category. Check your state DMV and local ordinances before riding on public roads or bike paths.
Can I pedal it if the battery runs out?
Yes. The 7-Speed Shimano derailleur works independently of the motor. At approximately 68 lb the machine is heavy, so unassisted pedalling is slow going, but it is entirely possible on flat ground.
Is the battery removable for indoor charging?
Yes. It unlocks with the supplied key and lifts out of its mount in a few seconds. You can also charge it in place through the frame-side charge port. Two keys are supplied.
Will the brakes cope with the speed and the weight?
Hydraulic disc brakes, front and rear are the appropriate specification for a 28 mph machine weighing about 68 lb. Bed the pads in during the first few rides with 10-15 progressive stops from moderate speed to build the friction layer on the rotors, and brake earlier than you would on an unloaded bicycle.
How much can it carry?
The rated load is 330 lb (150 kg) in total, which includes the rider, any passenger, and cargo. Staying inside that figure matters for the wheels and the frame, and it also matters for braking distance - a fully loaded machine needs noticeably more room to stop.
Quick Troubleshooting
Common issues and what to check first.
The motor does not engage when I twist the throttle.
Confirm the display is on and showing charge, the battery is locked into its mount, and both brake levers are fully released - the cut-off sensors disable motor drive while a lever is pulled. If the display shows an error code, note it and contact support before riding.
Range dropped noticeably compared with when it was new.
Check tire pressure first; a soft tire on pavement is by far the most common cause. Then consider temperature, since cold temporarily reduces available capacity. If range is down more than 30 percent year-round after many charge cycles, the pack is approaching the end of its service life.
The brakes feel spongy or weak at the lever.
Sponginess in a hydraulic system usually means air in the line or a fluid leak; in a cable system it usually means a stretched cable or glazed pads. Either way, stop riding and have the system inspected. Do not continue riding a 28 mph machine on compromised brakes.
The display shows an error code and the machine 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 - codes map to specific faults in the controller, motor, throttle, or sensor circuits.
There is a knocking or rattling noise over bumps.
Check that the axle hardware is torqued and the wheels are seated in the dropouts, then check the headset for play by holding the front brake and rocking the machine fore and aft. If the noise comes from the suspension, inspect the stanchions for scoring and have the unit serviced.
The chain skips under hard pedalling.
The derailleur indexing is most likely out of adjustment, or the chain and cassette are worn. Turn the barrel adjuster a quarter turn at a time to bring the indexing back. If it skips only in the smallest cogs, the cassette is worn and should be replaced together with the chain.

The specifications above show exactly what is under the surface, and the ride proves it every time. The HKM-0801363 pairs a 750 W rear hub motor (1500 W peak), Bafang, 48 V 15 Ah lithium-ion (720 Wh), Samsung cells, removable and lockable, a range of 30-55 mi (48-88 km), varies with terrain, rider weight, and assist level, so it is built for real-world rides rather than showroom specs.
Pre-Ride Safety Checklist
Run through these before every ride.
Check tire pressure and set it for the surface you plan to ride.
Squeeze both brake levers. They should firm up well before reaching the grip, with no sponginess that would indicate air in the line or a stretched cable.
Confirm the battery is seated and locked and that the display shows the state of charge you expect.
Spin both wheels and check that the rims run true and that nothing rubs the pads or the frame.
Verify that the axle hardware is tight and that the headset has no play when you rock the machine with the front brake applied.
Test the throttle at walking pace in a clear area before riding in traffic.
Switch on the headlight and tail-light if you will be riding near dusk, and wear a helmet rated for the speeds this machine reaches.
Check that both suspension units move freely and return without binding.

Important Safety Notes
Read before the first ride.
This 750 W bike is rated at 28 mph. Read the manual first and practise throttle and braking in an open, traffic-free area. Leave extra room for braking, since stopping distance grows fast with speed and load. Wear a helmet every ride; a certified downhill or motorcycle helmet is wise at 28 mph. Do not exceed the 330 lb (150 kg) load limit, including rider, cargo, and rack load. Confirm local law before riding on public roads. Bed the brakes in with 10-15 progressive stops over the first rides. Never ride through water deep enough to reach the motor or battery. Charge only with the supplied charger, indoors and attended. Never open, puncture, or modify the pack. Slow down substantially on gravel, wet surfaces, and steep descents.
