Overview
The HKM-5552723 is built around a rigid steel-and-aluminum cruiser frame with a long, flat bench seat and a headlight mounted in the front number-plate area. The 20-inch wheels and wide handlebar give it a muscular stance while keeping the overall length manageable for city parking and storage.
Propulsion comes from a 1500 W brushless rear hub motor with enough torque to pull away quickly from stops and maintain speed on moderate hills. The 48 V 36 Ah lithium pack stores 1728 Wh of energy, far more than most commuter e-bikes, which helps offset the higher power draw of the large motor.
Real-world range is approximately 25 miles under mixed throttle and assist use. Using lower assist levels and pedaling actively can extend that figure; sustained top-speed throttle riding will reduce it. The pack recharges from empty in 6-8 hours with the supplied fast charger.
Hydraulic disc brakes at both wheels provide the stopping power appropriate for a 28 mph cruiser. The 7-speed drivetrain lets you pedal comfortably at lower speeds or extend range by contributing human power on flat sections.
Key Features
1500 W Brushless Rear Hub Motor
A high-output rear hub motor delivers strong acceleration and maintains cruising speed with minimal noise. The direct-drive layout has no chain or belt between the motor and wheel, so maintenance is limited to axle-nut torque checks.
48 V 36 Ah Lithium Pack (1728 Wh)
The large-capacity battery is housed in a lockable side case and lifts out for indoor charging. 1728 Wh is enough for extended city rides and reduces the need to charge after every short trip.
Hardtail Cruiser Frame With Rear Shock
The rigid rear triangle keeps the bike simple and predictable, while a rear shock under the seat smooths out potholes and expansion joints. The moped-style geometry offers an upright, relaxed riding position.
Hydraulic Disc Brakes, Front and Rear
Sealed hydraulic lines deliver light, consistent lever feel and strong stopping power. Power-off levers cut motor power as soon as either brake is applied.
7-Speed Indexed Drivetrain
A 7-speed cassette and thumb shifter let you choose a comfortable pedaling cadence from walking pace up to cruising speed. Lower gears help when climbing; higher gears let you contribute power on flats.
20 x 4.0 in All-Terrain Fat Tires
The wide tires spread weight over a large contact patch for grip on loose gravel, wet pavement, and packed dirt. On city streets they also absorb small bumps that would rattle a narrower tire.
LED Headlight and Integrated Tail-Light
A bright LED headlight draws power from the main battery, and a brake-activated tail-light improves rear visibility at dusk and in traffic.
Long Bench Seat and Rear Rack
The broad bench seat supports a comfortable upright posture, and the integrated rear rack is rated for up to 99 lb of cargo or a small bag.

Battery, Range, and Charging
The 48 V 36 Ah pack stores 1728 Wh of energy, roughly three times the capacity of a typical commuter e-bike. That reserve is what lets the 1500 W motor deliver strong acceleration and range without requiring a charge after every short trip.
Real-world range depends on how much you use the throttle, rider weight, tire pressure, and terrain. Mixed throttle-and-assist riding at moderate speeds typically returns around 25 mi. Lower assist levels with active pedaling can extend range; sustained top-speed riding will reduce it.
Tip: Store the pack at 30-70 percent charge if the bike will sit unused for more than a month. Charging indoors at room temperature extends usable pack life.
The battery unlocks with the supplied key and lifts out of the side case for charging at a desk or wall outlet. Two keys are included.
Daily Use & Care
- Run 15-20 psi on pavement for lower rolling resistance; drop to 10-12 psi for gravel and dirt.
- Rinse the frame, rims, and drivetrain after riding on salted roads or wet gravel.
- Check axle nuts and stem bolts weekly; hub-motor torque works fasteners loose faster than on a conventional bike.
- Wipe and re-lubricate the chain every 100-150 mi, or after any ride through standing water or dust.
- Inspect brake pad thickness monthly; hydraulic pads wear silently until they are gone.
- Charge indoors at room temperature and unplug the charger once the indicator turns green.
- Keep the display and charge port covers closed when the bike is parked outside.

Frequently Asked Questions
How much assembly is required out of the box?+
The bike ships about 85 percent assembled. Remaining steps are fitting the front wheel, straightening and bolting the handlebar, installing the pedals and seat, and checking brake alignment. Budget 30-45 minutes.
What is the real-world range?+
Plan for up to 25 mi under mixed throttle-and-assist use. Throttle-only riding at top speed will reduce range; pedaling actively at lower assist extends it.
Is a license or registration required?+
Regulations vary by jurisdiction. A 1500 W motor with a 28 mph top speed may exceed standard e-bike limits in some areas. Check your state and local laws before riding on public roads.
How long does the battery take to charge?+
About 6-8 hours from fully empty with the supplied fast charger. Partial top-ups take proportionally less time.
Can I ride it in the rain?+
Light rain and splashes are fine, but avoid submersion and pressure-washing. Dry the bike and charge port after wet rides.
Can I pedal it without motor assistance?+
Yes. The 7-speed drivetrain works independently. Unassisted pedaling is slower because of the bike's weight, but it is possible on flat ground.
What is the rear rack rated for?+
The integrated rear rack is rated for up to 99 lb (45 kg). Do not overload it, and secure cargo so it cannot shift while riding.
Is the battery removable for indoor charging?+
Yes. It unlocks with the supplied key and lifts out of the side case.

Why Choose the HKM-5552723
High-Capacity Battery for Long Days
A 1728 Wh battery means fewer charges and more miles between plug-ins. That is useful for delivery riders, commuters, and anyone who dislikes daily charging routines.
Moped Style in a Compact Package
The 20-inch wheels and short wheelbase make the bike easier to park and maneuver than full-size motorcycles, while the bench seat and handlebar stance deliver cruiser attitude.
Hydraulic Brakes Matched to the Speed
A 28 mph cruiser needs brakes that can shed heat and maintain feel. Hydraulic discs do both, with less hand fatigue than mechanical alternatives.
Throttle or Pedal-Assist Riding
Use the twist throttle for motorcycle-style acceleration, or select a pedal-assist level and add your own power to extend range.
Fat Tires for Mixed Surfaces
20 x 4.0 in tires handle pavement, gravel, hardpack dirt, and light snow, so your route options are not limited by tire width.
Distinctive Finish
The black-and-pink color scheme stands out while remaining neutral enough for daily use. The finish is UV-resistant to reduce fading.

Pre-Ride Safety Checklist
- Check tire pressure and set it for the terrain: 15-20 psi for pavement, 10-12 psi for gravel or dirt.
- Squeeze both brake levers. They should firm up well before reaching the grip, with no sponginess.
- Confirm the battery is seated and locked, and that the display shows the expected state of charge.
- Spin both wheels and check that nothing rubs the brake pads or frame.
- Verify axle nuts and stem bolts are tight, and that the headset has no play.
- Test the throttle at walking pace in a clear area before riding in traffic.
- Switch on the headlight and tail-light if riding near dusk, and wear a helmet.
- Check that cargo on the rear rack is secured and within the 99 lb limit.
Quick Troubleshooting
The motor does not engage when I twist the throttle.+
Confirm the display is on, 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.
Range dropped noticeably compared with when it was new.+
Check tire pressure and consider temperature effects. If range remains down more than 30 percent year-round, the pack may be near end of life.
The brakes feel spongy at the lever.+
Sponginess usually indicates air in the line or a fluid leak. Have the hydraulic system bled and inspected before riding at speed.
The chain skips under hard pedaling.+
The derailleur indexing is likely out of adjustment, or the chain and cassette are worn. Adjust the barrel adjuster a quarter turn at a time.
The display shows an error code.+
Power the system off, wait 30 seconds, and switch it back on. If the code returns, note it and contact support.
The headlight does not turn on.+
Check the light switch setting on the display and confirm the battery has charge. Inspect the connector if the problem persists.
