HKM-1522259 350 W Rear Hub Motor, 48 V 7.5 Ah Battery, 20 mph Top Speed, 14 x 1.95 in City Tires, Electric Bike
HKM-1522259
350 W 20 mph Electric Bike
The HKM-1522259 is built around an aluminum alloy folding frame and a 350 W Rear Hub motor that delivers smooth, clutch-free acceleration up to 20 mph. The 48 V 7.5 Ah lithium pack stores 360 Wh of energy, enough for 15-30 mi of real-world riding depending on how much you pedal and the terrain you cover.
Key Features
8 details that make the HKM-1522259 a dependable ride.
350 W Rear Hub
A 350 W brushless rear hub, peak 500 W delivers smooth, predictable acceleration up to 20 mph. The motor sits in the rear hub for direct drive with no chain or belt to maintain between motor and ground.
360 Wh Removable Battery
The 48 V 7.5 Ah pack stores 360 Wh of energy. It unlocks with the supplied key and lifts out of the frame for indoor charging, or charges in place through the frame-side port. A full recharge from empty takes about 3-5 h with the supplied 2 A charger.
V-Brake Front + Drum Rear
Both calipers are actuated with predictable, light lever effort. Power-off brake levers cut motor drive the instant either lever is pulled - a meaningful safety feature on a 20 mph bike. Pads and rotors are replaceable for long service life.
Single-Speed Drivetrain
A Single-Speed drivetrain with a Shimano index shifter gives usable pedaling cadence from walking pace up to cruising speed. The wide gear range lets heavier riders climb grades without overheating the battery.
Rigid
A rigid takes the bigger hits before they reach the rider. The setup is tuned for the 220 lb load rating and the varied terrain this bike is built to handle.
LED Headlight
A led headlight, brake light runs off the main battery, so there is nothing extra to charge. The light is wired through the controller so it does not need its own switch.
Compact LCD
The compact lcd shows speed, battery level, assist mode, odometer, and trip distance at a glance. Buttons on the left grip let the rider change assist levels without taking a hand off the bar.
Integrated Lighting and Controls
A led headlight, brake light comes pre-wired and runs off the main battery. Twist-grip throttle with five pedal-assist levels gives you full control over how much electric help you add to your own pedaling.
Overview
Built for the ride ahead.
The HKM-1522259 is built around an aluminum alloy folding frame and a 350 W Rear Hub motor that delivers smooth, clutch-free acceleration up to 20 mph. The 48 V 7.5 Ah lithium pack stores 360 Wh of energy, enough for 15-30 mi of real-world riding depending on how much you pedal and the terrain you cover. A Rigid paired with v-brake front + drum rear keeps the ride composed on broken pavement, gravel, and park paths. The 14 x 1.95 in roll over obstacles that would stop a narrower tire, while the Single-Speed drivetrain lets you add human power whenever you want to stretch the range. Practical details make the bike useful beyond recreation.
Light, Stiff Aluminum Frame
An aluminum frame keeps the HKM-1522259 light to lift yet stiff to ride.
What looks simple took careful engineering, because less is the harder thing to earn. Composed where it matters, light everywhere else — that is the whole idea.
Full Specifications
Measurements are shown in US customary units first, with metric equivalents in parentheses.
Battery, Range, and Charging
Up to 15-30 mi per charge.
The HKM-1522259 runs on a 350 W Rear Hub, 500 W peak, 48 V 7.5 Ah lithium-ion (360 Wh), removable, a range of 15-30 mi, varies with terrain, rider weight, and assist level, a top speed of 20 mph, engineered for dependable day-to-day performance.
Daily Use & Care
A short routine keeps the ride quiet and the range where it should be.
Tire pressure sets the character of the bike. Run 12-18 psi on pavement for lower rolling resistance; drop to 8-12 psi for gravel and dirt so the tire 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 over time if left in place.
Check that both axle nuts 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 dusty conditions.
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. Unplug the charger once the indicator turns green rather than leaving it connected for days.
Keep the display and charge port covers closed when the bike is parked outside so moisture stays out of the connectors.

Why Choose the HKM-1522259
6 reasons it earns its place.
Built for Daily Transport
A stable geometry, a wide saddle, and integrated lights turn this model into a practical transport tool rather than a recreational toy. You can run errands, commute to work, or explore trails on the same bike without swapping seats or adding accessories.
Front Suspension for Real Roads
Potholes, expansion joints, brick-paved lanes, and gravel shortcuts all become rideable surfaces when the suspension absorbs what a rigid frame would transmit directly to the rider. The tuning is matched to the 220 lb load rating.
Throttle or Pedal
Twist the throttle for immediate acceleration, or shift through the cassette and pedal. Most owners mix both: throttle to get moving from a stop, pedals to extend the range, and motor for hills.
Long-Range 360 Wh Battery
The 48 V 7.5 Ah pack stores 360 Wh, enough for 15-30 mi of mixed riding. Remove it for indoor charging or top it up in place through the frame port.
Easy to Live With
The folding frame and moderate weight keep the bike easy to roll into a closet or load onto a rack.
Rated for 220 lb Load
The frame, wheels, and brakes are specified for a combined 220 lb of rider and cargo. That margin means confident handling with a backpack, groceries, or a loaded rear rack.
Every Component Chosen for Real-World Use
Every component of the HKM-1522259 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-1522259 pairs a 350 W Rear Hub, 500 W peak, 48 V 7.5 Ah lithium-ion (360 Wh), removable, a range of 15-30 mi, 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-1522259.
How much assembly is required out of the box?
The bike ships approximately 85 percent assembled. Remaining steps are fitting the front wheel, straightening and bolting the handlebar, installing the pedals and saddle, and checking brake alignment. Budget 30-45 minutes with the supplied tools.
What is the actual range I should plan for?
Plan for 15-30 mi depending on how much you pedal. Throttle-only riding at higher speeds lands closer to the low end. Moderate pedal-assist on mixed terrain regularly returns the high end.
Is a license or registration required?
Rules vary by state and locality. A 350 W motor with 20 mph top speed may exceed the limits 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.
Is the battery removable for indoor charging?
Yes. It unlocks with the supplied key and lifts out of the frame. You can also charge it in place through the frame-side charge port.
Will the brakes handle the speed and the load?
The v-brake front + drum rear are the appropriate specification for a 20 mph bike of this weight. Bed the pads in during the first few rides with 10-15 progressive stops.
Can I pedal it if the battery runs out?
Pedaling is possible with the battery off but the bike is heavy; plan on a slow walk home rather than a confident ride.
How long does the battery take to charge?
About 3-5 h from fully empty with the supplied 2 A charger. Partial top-ups take proportionally less time; there is no need to run the pack down before recharging.
What kind of riding is this model built for?
The compact 14-inch folding electric bike is suited to commuting, errands, and weekend recreation. the 220 lb load rating and stable geometry make it a practical daily-transport option as well as a recreational ride.
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 shows charge, the battery is locked into place, and both brake levers are fully released. Brake cut-off sensors disable the motor while a lever is pulled. If the display shows an error code, note it and contact support.
Range dropped noticeably compared with when it was new.
First check tire pressure; a soft tire on pavement is the most common cause. Then consider temperature. If range is down more than 30 percent year-round after many charge cycles, the pack may be approaching the end of its service life.
The brakes feel weak or uneven.
Check pad thickness and rotor alignment. Sponginess in a hydraulic system means air in the line or a fluid leak. Stop riding and have the system inspected. Do not continue on compromised brakes.
The chain skips under hard pedaling.
Inspect the belt or chain for wear. Skipping under load usually points to a stretched component.
The suspension feels harsh or noisy.
Check air pressure (if equipped) and that the wheel is seated in the dropouts. If noise persists, the unit may need service. Inspect stanchions for scoring and have a shop rebuild the lowers if needed.
The display shows an error code and the bike 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 for diagnosis.

From Frame to Wheels
From the frame to the wheels, the HKM-1522259 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-1522259 pairs a 350 W Rear Hub, 500 W peak, 48 V 7.5 Ah lithium-ion (360 Wh), removable, a range of 15-30 mi, 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 terrain you plan to ride: 12-18 psi for pavement, 8-12 psi for gravel or dirt.
Squeeze both brake levers. They should firm up well before reaching the grip, with no sponginess that would indicate a problem.
Confirm the battery is seated and locked, and that the display shows the expected state of charge.
Spin both wheels and check that the rims run true and nothing rubs the brake pads or the frame.
Verify the quick-release levers and axle nuts are tight, and that the headset has no play when you rock the bike with the front brake applied.
Test the throttle at walking pace in a clear area before riding in traffic or with a passenger.
Switch on the headlight and tail-light if you will be riding near dusk, and wear a helmet rated for the speeds this bike reaches.
If carrying cargo, confirm the load is balanced and within the 220 lb rating before you ride.

Important Safety Notes
Read before the first ride.
This 350 W bike is rated at 20 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. Do not exceed the 220 lb (100 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.
