HKM-2767443 750 W 48 V Folding Fat Tire Electric Bike, 13 Ah Battery (624 Wh), 31 mph Top Speed, 7-Speed Shimano
HKM-2767443
750 W 31 mph Folding Fat Tire Electric Bike
The HKM-2767443 is positioned as a folding fat tire electric bike rather than a general-purpose bicycle with a motor bolted on. The defining detail is a steel folding frame that trades a few pounds for a higher fatigue margin at the hinge than aluminum equivalents, and the rest of the specification is chosen to support that: 20 x 4.0 in tires, a folding high-carbon steel frame and front suspension fork, 80 mm travel.
Key Features
8 details that make the HKM-2767443 a dependable ride.
750 W Rear Hub Motor
A 750 W rear hub motor delivers 75 N.m and holds 31 mph on level ground. Brushless construction means no brushes to wear and no routine service inside the motor itself.
Locking Frame and Stem Hinges
A cam-lock hinge at the centre of the main tube and a second at the stem let the HKM-2767443 fold to roughly half its ridden length. Both hinges carry a secondary safety catch that must be released deliberately.
20 x 4.0 in All-Terrain Tires
The 20 x 4.0 in casing runs at low pressure so the contact patch spreads instead of digging in. That is what lets the HKM-2767443 hold a line on gravel, packed sand and wet grass, and the air volume doubles as suspension on washboard surfaces.
48 V 13 Ah Lithium Battery (624 Wh)
The pack stores 624 Wh, enough for 25-31 miles depending on assist level, rider weight and terrain. Cells are matched and monitored by a BMS that manages over-charge, over-discharge, short circuit and temperature limits.
Mechanical Disc
Braking is the part most often under-specified on a bike this quick. The HKM-2767443 uses Mechanical disc, 160 mm rotors at both ends so lever effort stays low and stopping distance stays predictable with a load on board or on a long descent.
Folding high-carbon Steel Chassis
The Folding high-carbon steel frame is sized around a 330 lb total load rating and hosts the battery, motor cabling and rack mounts internally where possible. Welds at the head tube and bottom bracket are gusseted for repeated off-road loading.
Sprung Comfort Saddle
A wide saddle on a suspension post takes the edge off surfaces the 20 x 4.0 in tires pass through. Height adjusts with a quick-release clamp, and the post is marked so you can return to your own setting after someone else rides it.
Rear Rack and Tie-Down Points
The welded rear rack takes panniers, a strapped crate or a trunk bag, rated for roughly 40 lb of distributed load inside the 330 lb total limit. Multiple anchor points keep a load still on rough ground.
Overview
Built for the ride ahead.
The HKM-2767443 is positioned as a folding fat tire electric bike rather than a general-purpose bicycle with a motor bolted on. The defining detail is a steel folding frame that trades a few pounds for a higher fatigue margin at the hinge than aluminum equivalents, and the rest of the specification is chosen to support that: 20 x 4.0 in tires, a folding high-carbon steel frame and front suspension fork, 80 mm travel. Drive comes from a 750 W rear hub motor fed by a 48 V 13 Ah pack holding 624 Wh. Peak torque is quoted at 75 N.m. The controller manages current, temperature and low-voltage cut-off, and assist is available up to 31 mph (50 km/h). Expect 25-31 miles from a charge; throttle-heavy riding on soft ground sits at the low end of that band and moderate pedal assist on firm surfaces at the high end.
Weatherproof Build, Rain or Drizzle
A weatherproof build lets the HKM-2767443 go out in the drizzle and come home unscathed.
Built for the life actually being lived, not the one staged for a photo. Nothing here is for show; everything here is for the ride. The HKM-2767443 pairs a 750 W rear hub motor, 48 V 13 Ah lithium-ion (624 Wh), a range of 25-31 mi, varies by assist, load and terrain, 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 25-31 mi per charge.
The HKM-2767443 runs on a 750 W rear hub motor, 48 V 13 Ah lithium-ion (624 Wh), a range of 25-31 mi, varies by assist, load and terrain, a top speed of 31 mph (50 km/h), engineered for dependable day-to-day performance.
Daily Use & Care
A short routine keeps the ride quiet and the range where it should be.
Check tire pressure before each ride; 20 x 4.0 in tires lose noticeable pressure week to week and under-inflation is the most common cause of disappointing range.
Squeeze both brake levers before setting off and confirm they firm up well before reaching the grip.
Inspect brake pads monthly and replace them once the friction material is under 1 mm.
Clean and lubricate the chain every few hundred miles, more often after wet or dusty rides, and wipe the excess off so it does not collect grit.
Check that the stem, saddle clamp, axle nuts and rack bolts are tight once a month.
Wipe salt, sand and mud off the frame and off the battery contacts after riding in them.
Store the bike dry and bring the battery indoors when the temperature drops below freezing.

Why Choose the HKM-2767443
6 reasons it earns its place.
Stores Where A Full-Size Bike Cannot
Folded, it goes in a car trunk, a hall closet or an RV bay. That is the difference between owning an e-bike and not being able to keep one.
Fits A Range of Riders
Saddle and bar adjustment cover a wide rider height band, so the same bike works for more than one person in a household.
Practical to Live With
Rack mounts, a lockable battery and a maintenance schedule that a home mechanic can follow keep the HKM-2767443 useful past the first season.
Travels with You
It fits in a vehicle without a rack, so the bike goes on the trip instead of staying in the garage.
Economical to Run
A full charge of the 624 Wh pack costs a few cents of electricity and replaces short car trips that cost dollars in fuel and parking.
Quiet Running
A brushless drive produces a low hum instead of engine noise, which keeps the bike welcome on shared paths and in early-morning neighbourhoods.
Every Component Chosen for Real-World Use
Every component of the HKM-2767443 is chosen for real-world use.

Frequently Asked Questions
Quick answers about the HKM-2767443.
What range should I actually expect?
Plan for 25-31 miles. The low figure reflects throttle-heavy riding on loose or hilly ground; the high figure reflects moderate pedal assist on firm surfaces. Rider weight, tire pressure, headwind and temperature all move the number.
How fast will it go and is that legal where I ride?
Assist is available to 31 mph (50 km/h). Class rules vary by state and by path operator - many shared paths cap e-bikes at 20 mph. Check local regulations before riding on public ground, and set the display limit lower where required.
How long does a charge take?
Five to eight hours from empty with the supplied charger. A partial top-up is proportionally quicker, and topping up before the pack is fully flat is better for cycle life than running it to zero every time.
How much does it weigh and can one person lift it?
Approximately 65 lb with the battery fitted. Removing the pack takes several pounds off. A vehicle rack rated for e-bike weight is recommended over a lightweight trunk-mounted rack.
What maintenance does it need?
Tire pressure before each ride, brake pad thickness and rotor condition monthly, chain clean and lube every few hundred miles, and a bolt check on the stem, saddle and rack monthly. The motor itself is sealed and needs no internal service.
How much assembly is required?
It ships roughly 85-90 percent assembled. Fit the front wheel, handlebar, pedals and saddle, check brake alignment and charge the battery fully before the first ride. Budget 30-45 minutes with the supplied tools.
Can it be ridden in the rain?
Yes, in normal rain. Connectors are sealed and the controller is protected, but the bike is water resistant rather than waterproof - do not pressure-wash it, ride it through deep water or leave it standing outdoors uncovered.
What is the load limit?
The HKM-2767443 is rated to 330 lb total including rider, clothing and cargo. Exceeding it stresses the frame, wheels and brakes and shortens the life of all three.
Quick Troubleshooting
Common issues and what to check first.
The motor does not engage at all.
Confirm the battery is switched on, seated and locked, and that the display powers up. Check the brake-lever cut-off switches - a sticking switch tells the controller you are braking and suppresses assist. Then check the main connector behind the battery cradle.
Range is well below the 25 mile figure.
Check tire pressure first; it is the single largest controllable factor. Then consider assist level, rider and cargo weight, headwind, gradient and temperature. A pack that has lost capacity permanently will also charge noticeably faster than when it was new.
The motor cuts out under load and recovers after a few minutes.
That is thermal or over-current protection. Ease off, drop to a lower gear so the drivetrain does more of the work on the climb, and let the system cool for ten minutes before continuing.
Braking feels soft or the lever pulls to the grip.
For mechanical disc, 160 mm rotors, check pad wear and rotor condition first. Cable systems usually need a barrel adjuster turn; hydraulic systems that stay soft after pad replacement need bleeding.
The drivetrain skips or will not hold a gear.
Index the 7-Speed Shimano with the barrel adjuster at the shifter, a quarter turn at a time, while the wheel is turning. Persistent skipping under power usually means a worn chain or cassette rather than an adjustment fault.
The display shows an error code.
Power the system off, wait 30 seconds and restart. If the code returns, write down the exact code and what you were doing when it appeared, then contact support - the code identifies which subsystem reported the fault.

From Frame to Wheels
From the frame to the wheels, the HKM-2767443 is built for consistent, confident performance.
The specifications above show exactly what is under the surface, and the ride proves it every time. The HKM-2767443 pairs a 750 W rear hub motor, 48 V 13 Ah lithium-ion (624 Wh), a range of 25-31 mi, varies by assist, load and terrain, so it is built for real-world rides rather than showroom specs.
Pre-Ride Safety Checklist
Run through these before every ride.
Confirm the battery is locked into its cradle and the display shows the charge you expect.
Set tire pressure to the range printed on the 20 x 4.0 in sidewall.
Check both brakes at walking pace before entering traffic or a trail.
Confirm the quick-release levers on the wheels and seat post are closed and tight.
Test the throttle briefly in a clear space so you know how sharply it responds today.
Check the headlight and tail light if there is any chance of riding at dusk.
Put a helmet on. At 31 mph the consequences of a fall are not bicycle-speed consequences.

Important Safety Notes
Read before the first ride.
This 750 W bike is rated at 31 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 31 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.
