HKM-0768595 750W 20 x 4.0 in Folding Fat Tire Electric Bike, Dual 48V Batteries 28.8Ah / 1382Wh, 7-Speed Shimano, 28 mph
HKM-0768595
750 W 28 mph Fat Tire Electric Bike
The defining feature of the HKM-0768595 is its two-pack electrical system. A 48 V 14.4 Ah pack sits in the folding down tube and a second 48 V 14.4 Ah pack mounts on the rear rack.
Key Features
8 details that make the HKM-0768595 a dependable ride.
750 W Brushless Rear Hub Motor
The motor is laced into the rear wheel with no gearbox or secondary chain in the drive path. Around 85 N.m of torque pulls away cleanly from a stop even loaded, and the sealed casing needs nothing beyond correctly torqued axle nuts.
Dual 48 V Packs Totalling 28.8 Ah (1382 Wh)
Two independent 14.4 Ah packs, one in the frame and one on the rear rack, both removable with a key. Either can run the bike alone, which means you can charge one indoors while the other stays on the bike, or carry a spare on long rides and swap in seconds.
Folding Frame and Folding Stem
A cam-lock hinge halves the down tube and a second hinge drops the stem, taking the bike down to roughly 39 x 24 x 32 in. Both hinges use safety catches that must be released deliberately, so neither can open under load.
Hydraulic Disc Brakes with 180 Mm Rotors
Sealed hydraulic lines run to both calipers on 180 mm rotors - the right size for a heavy fat-tire bike at 28 mph. Lever effort stays light as the rotors heat, and motor cut-off switches kill drive the instant a lever moves.
7-Speed Shimano Derailleur Drivetrain
A Shimano index shifter and 7-speed freewheel give real gearing rather than a single ratio. That matters on a folding bike with 20 in wheels, where the gearing has to cover both a standing-start climb and a 28 mph cruise.
20 x 4.0 in Fat Tires
Wide casings at low pressure spread the load and add a suspension effect of their own. The knobby tread grips gravel, damp grass, packed sand, and light snow, and the puncture-resistant casing shrugs off the debris found on road shoulders.
LED Headlight
The headlight and brake-activated tail-light run from the main pack. Integrated turn signals in the tail-light housing are operated from a bar-mounted switch, which is genuinely useful on a bike ridden in traffic at road speeds.
Bluetooth App: Ride Data and Motor Lock
The bike pairs with a phone app over Bluetooth. The app mirrors speed, battery state for each pack, assist level, and trip data, logs routes, and can electronically lock the motor so the bike will not drive if it is moved without you.
Overview
Built for the ride ahead.
The defining feature of the HKM-0768595 is its two-pack electrical system. A 48 V 14.4 Ah pack sits in the folding down tube and a second 48 V 14.4 Ah pack mounts on the rear rack. The controller draws from one at a time, so you can ride on the frame pack alone and keep the rack pack as a fully charged reserve, or run both for a genuine all-day range. Power is a 750 W brushless rear hub motor with 1500 W peak output and around 85 N.m of torque. That is enough to hold 28 mph on the flat with a solo rider and to climb the sort of grades that stall smaller folding bikes. A thumb throttle gives power without pedalling. Honest range numbers matter more than headline claims.
App Control in Your Pocket
App control puts speed, lock, and battery readout for the HKM-0768595 in your pocket.
Reliability is a feeling first and a number second. Built for the life actually being lived, not the one staged for a photo. The HKM-0768595 pairs a 750 W brushless rear hub motor, 1500 W peak, Two 48 V 14.4 Ah lithium-ion packs, 28.8 Ah / 1382 Wh combined, both removable, a range of 35-50 mi (56-80 km) on one pack; 70-100 mi (113-161 km) on both, under moderate pedal-assist, 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 35-50 mi (56-80 km) on one pack; 70-100 mi (113-161 km) on both per charge.
The HKM-0768595 runs on a 750 W brushless rear hub motor, 1500 W peak, Two 48 V 14.4 Ah lithium-ion packs, 28.8 Ah / 1382 Wh combined, both removable, a range of 35-50 mi (56-80 km) on one pack; 70-100 mi (113-161 km) on both, under moderate pedal-assist, a top speed of 28 mph (45 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.
Set tire pressure for the surface: 18-22 psi on pavement, 12-15 psi on gravel, sand, or snow so the casing can flatten and grip.
Check both folding hinges before every ride. The cam levers should need firm hand pressure to close and the safety catches must be engaged.
Alternate which pack you ride on rather than always draining the same one, so both packs age at a similar rate.
Rinse the frame, rims, and drivetrain with fresh water after riding on salted roads, then dry and re-lubricate the chain.
Wipe and re-lubricate the chain every 100-150 mi; a 7-speed chain on a heavy bike wears faster than on an unpowered bicycle.
Inspect the hydraulic pads monthly and replace them once the friction material is under 1 mm. Do not wait for noise.
Update the app when prompted; firmware updates are delivered to the controller over Bluetooth and occasionally change assist mapping.

Why Choose the HKM-0768595
6 reasons it earns its place.
Range You Can Verify
Two physical packs are a more honest answer to range anxiety than an optimistic number on a spec sheet. If one runs out, the other is full.
Folds Into the Trip
Down to roughly 39 x 24 x 32 in, the bike travels in a car trunk or an RV bay and comes out at the far end ready to cover 70-100 mi.
Torque Sensing
Assist output tracks how hard you actually push the pedals, so power arrives smoothly instead of switching on and off as the cranks turn.
Simple Where It Counts
Hub drive, sealed hydraulic lines, and key-removable packs mean the wear items are limited to chain, pads, and tires.
Charge on Your Terms
Both packs lift out with a key, so an apartment, an office, or a hotel room all become charging points.
Built to Be Left Outside
Sealed connectors, covered charge ports, locking pack mounts, and an app-level motor lock suit a bike that gets parked at a rack.
Every Component Chosen for Real-World Use
Every component of the HKM-0768595 is chosen for real-world use.

Frequently Asked Questions
Quick answers about the HKM-0768595.
How much assembly is required?
The bike ships folded and roughly 90 percent assembled. What remains is unfolding and locking both hinges, fitting the front wheel and pedals, straightening the handlebar, and a brake check. Budget 30-40 minutes.
Can I ride with only one battery fitted?
Yes. Either pack alone will run the bike normally. Removing the rack pack saves about 11 lb, which is worth doing for short local trips.
What range should I realistically expect?
On one pack, 35-50 mi with moderate pedal-assist or 25-30 mi on throttle alone. With both packs, 70-100 mi assisted. Headline figures assume a light rider, flat ground, low assist, and full tires - plan for the lower end of each band.
How do the two packs work together?
They do not run in parallel. The controller draws from one pack at a time and you switch over at the roadside when the first is low, which keeps the reserve genuinely full rather than half-drained.
What does the Bluetooth app actually do?
It mirrors the display, shows the state of charge of each pack separately, logs ride routes and distance, exposes assist settings, and can electronically lock the motor so the bike will not drive if it is moved without you.
Is a licence or registration required?
Rules vary by state and city. A 750 W motor with a 28 mph top speed and a throttle sits at or above the top of the common three-class e-bike framework in many US jurisdictions. Check your state DMV and local ordinances before riding on public roads or bike paths.
How small does it actually fold?
Roughly 39 x 24 x 32 in. That fits most car trunks, SUV cargo areas, and RV storage bays. At about 79 lb it is better rolled rather than carried.
Can I pedal it with both packs empty?
Yes. The 7-Speed Shimano drivetrain is fully mechanical. The bike is heavy, so unassisted pedalling is slow on hills, but it works on level ground.
Quick Troubleshooting
Common issues and what to check first.
The motor will not engage.
Check that the pack selector is fully in one position rather than between the two, that the selected pack shows charge, and that both brake levers are released - the cut-off switches disable drive while a lever is pulled.
The app will not connect to the bike.
Switch the bike on first, then open the app. If it still will not pair, forget the device in your phone Bluetooth settings and pair again from inside the app. Only one phone can hold an active connection at a time.
One pack seems to drain much faster than the other.
Check that you have not been riding almost exclusively on that pack; alternate them so they age evenly. If the difference persists with equal use after many cycles, have the weaker pack tested.
The folding hinge feels loose when closed.
The cam tension is adjustable at the hinge nut. Tighten it a quarter turn at a time until the lever needs firm hand pressure to close, then re-check. Do not ride the bike until the hinge is solid.
The brakes feel spongy at the lever.
Sponginess in a hydraulic system means air in the line or a fluid leak. Stop riding and have the system bled and inspected before using the bike again at road speed.
Assist feels weak or arrives late when pedalling.
A torque-sensed system responds to pedal pressure, so soft pedalling in a high gear produces little assist. Shift down and push harder. If the behaviour is unchanged in low gear, the sensor may need recalibration through the app.

From Frame to Wheels
From the frame to the wheels, the HKM-0768595 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-0768595 pairs a 750 W brushless rear hub motor, 1500 W peak, Two 48 V 14.4 Ah lithium-ion packs, 28.8 Ah / 1382 Wh combined, both removable, a range of 35-50 mi (56-80 km) on one pack; 70-100 mi (113-161 km) on both, under moderate pedal-assist, so it is built for real-world rides rather than showroom specs.
Pre-Ride Safety Checklist
Run through these before every ride.
Confirm both folding hinges are closed, the cam levers are firm, and the safety catches are engaged. Never ride with a hinge that closes loosely.
Check tire pressure and set it for the surface: 18-22 psi on pavement, 12-15 psi off road.
Pull both brake levers. They should firm up well before the grip, with no sponginess suggesting air in the hydraulic line.
Verify which pack is selected and that the display shows the charge you expect for it.
Make sure the rack pack is latched and locked; an unlatched pack can shift under braking.
Spin both wheels and confirm nothing rubs the pads, the fender, or the frame.
Test the throttle at walking pace in a clear area, and check the turn signals are working before riding in traffic.
Wear a helmet rated for the speeds this bike reaches, and switch the lights on for any ride near dusk.

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 400 lb (181 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.
