Overview
The HKM-5285587 is a motorcycle-style machine with a low seat, wide bars, and a 17 in wheel size that keeps the ride stable at speed. The step-through-ish frame is easy to mount, and the upright position gives a clear view of traffic.
A 2000 W brushless rear hub motor with a 3500 W peak rating drives the rear wheel with low loss, fed by two 48 V 20 Ah packs that combine for 1920 Wh. The twist throttle gives immediate acceleration and 3 ride modes let you trade punch for range.
With both packs full, range runs 60-90 mi depending on how you ride. Gentle speeds and rolling terrain reach the upper figure; sustained full-throttle work pulls toward the lower end. The packs recharge together in about 7-9 hours on the supplied chargers.
Comfort and control come from a dual hydraulic suspension - an inverted front fork and a rear mono-shock - and hydraulic disc brakes at both ends. The LED headlight and tail light keep you visible at dusk, and the 17 in street tires hold a confident line through corners.
Key Features
2000 W Brushless Rear Hub Motor
A 2000 W brushless motor (3500 W peak) is laced into the rear wheel hub for low drive loss and low maintenance. Peak output launches from a stop and holds 50 mph on flat road without strain.
Dual 48 V 20 Ah Lithium Packs (1920 Wh)
Two removable packs combine for 40 Ah and 1920 Wh, enough for long distance rides between charges. Each lifts out with a key for indoor charging; a full recharge from empty takes about 7-9 hours on the supplied chargers.
Dual Hydraulic Suspension
An inverted front fork and a rear mono-shock soak up road imperfections so the rider stays relaxed and the tire stays planted. Travel is tuned for street use and light rough patches.
Hydraulic Disc Brakes, Front and Rear
Sealed hydraulic lines actuate both calipers with light, predictable lever effort. Power-off levers cut motor drive the instant either is pulled - a real safety feature on a 50 mph machine.
Chain Drive with 14T Sprocket
A 520 chain with a 14T front and 48T rear sprocket transfers motor power to the rear wheel efficiently. The layout is simple to inspect and service, and replacement links are widely available.
17 in Street Tires
The 17 in wheels wear street-tuned tires with a tread that balances dry and wet grip and rolls efficiently on pavement for stable, quiet high-speed cruising.
LED Headlight and Tail Light
A bright LED headlight runs off the main packs and lights the road ahead; a tail and brake light increase visibility from behind when riding at dusk or in traffic.
Rear Rack and Passenger Pegs
A welded rear rack carries gear for long rides, while fold-down passenger pegs let a second rider come along within the 330 lb load limit.

Battery, Range, and Charging
The twin 48 V 20 Ah packs store a combined 1920 Wh. That headroom is what lets the HKM-5285587 cover long distances at speed without a mid-route charge.
Real-world range depends on how hard you ride. Gentle speeds and rolling terrain land near the top of the 60-90 mi band; sustained full-throttle work pulls toward the lower end. Cold weather below 40 F (4 C) temporarily costs 10-20 percent of available capacity.
Tip: Store the packs between 30 and 70 percent charge if the bike will sit for more than a month, and top them up every 4-6 weeks. Charging indoors at room temperature extends usable pack life.
Each pack unlocks with the supplied keys and lifts out of the frame in a few seconds. Two keys are included; charging in place through the frame-side port works equally well.
Daily Use & Care
- Set tire pressure to the placard on the sidewall; street tires run higher pressure than fat tires for stable handling at speed.
- Rinse the frame, rims, and chain after riding in rain or on salted roads.
- Lube and check the 520 chain every 150-200 mi, or after any ride through water or dust.
- Inspect brake pad thickness monthly and replace when under 1 mm.
- Check axle nuts and stem bolts before the first ride of each week.
- Charge indoors at room temperature and unplug once green.
- Keep the display and charge port covers closed when parked outside.

Frequently Asked Questions
How much assembly is required out of the box?+
The motorcycle ships approximately 85 percent assembled. Remaining steps are fitting the front wheel, straightening and bolting the handlebar, and checking brake alignment. Budget 30-45 minutes with the supplied tools.
Can it carry a passenger?+
Yes, within the 330 lb total load rating. Fold-down passenger pegs and the rear pad are sized for a second rider; with two riders, range drops by 30-40 percent versus solo.
What range should I plan for?+
Plan 60-90 mi depending on how you ride. Gentle speeds and rolling terrain reach the upper end; sustained full-throttle work pulls toward the lower end. Cold weather and soft tires both reduce range.
Is a license or registration required?+
Rules vary by state and locality. A 2000 W motor with 50 mph top speed places this vehicle outside the standard three-class e-bike framework in most US jurisdictions, typically in a motorcycle category. Check your state DMV before riding on public roads.
How long does the battery take to charge?+
About 7-9 hours from fully empty with both supplied 3 A chargers. Partial top-ups take proportionally less time.
Can it be pedaled?+
No - the HKM-5285587 is a throttle-only electric motorcycle with no pedals. Range comes from the battery packs, not rider effort.
Are both batteries removable?+
Yes. Both unlock with the supplied keys and lift out of the frame, or charge in place through the frame-side port.
Will the brakes handle the speed?+
Hydraulic disc brakes front and rear are sized for a 50 mph machine. Bed them in with 10-15 progressive stops during the first few rides; brake earlier than solo when carrying a passenger.

Pre-Ride Safety Checklist
- Check tire pressure against the sidewall placard; street tires need higher pressure than fat tires for stable handling at speed.
- Squeeze both brake levers - they should firm well before the grip with no sponginess.
- Confirm both batteries are seated and locked and the display shows charge.
- Spin both wheels and check the rims run true and nothing rubs the calipers or frame.
- Verify axle nuts and stem bolts are tight, headset has no play 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 near dusk, and wear a helmet rated for these speeds.
- If carrying a passenger, confirm both foot pegs are deployed before they mount.
Quick Troubleshooting
The motor does not engage when I twist the throttle.+
Confirm the display is on, both batteries are locked in place, and both brake levers are fully released - brake cut-off sensors disable the motor while a lever is pulled. Note any error code and contact support.
Range dropped noticeably compared with when it was new.+
First check tire pressure; a soft tire is the most common cause. Cold weather temporarily reduces capacity. If range is down more than 30 percent year-round, a pack may be near end of life.
The brakes feel spongy at the lever.+
Sponginess in a hydraulic system means air in the line or a leak. Stop and have the system bled. Do not ride on compromised brakes at this speed.
The chain skips or jumps under power.+
The chain may be loose or the sprockets worn. Adjust tension a quarter turn at a time and inspect the 14T and 48T sprockets for hooked teeth. Replace the chain and sprockets together if wear is advanced.
The front fork rattles over bumps.+
Check the axle is fully seated and the wheel is in the dropouts. If the rattle persists, the fork may need service.
The display shows an error code and the bike will not move.+
Power off, wait 30 seconds, switch back on. If it returns, note the exact code and conditions, then contact support.

Important Safety Notes
This is a high-output electric vehicle capable of 50 mph. Read the manual fully before the first ride and practice throttle control in an open, traffic-free area until the response feels predictable. Carry a passenger only after you are comfortable riding solo at speed.
- Wear a helmet on every ride. At 50 mph a certified motorcycle or downhill helmet is the minimum; an ordinary bicycle helmet is not enough.
- Do not exceed the 330 lb (150 kg) load capacity, which includes the rider, any passenger, and cargo.
- Check local law before riding on public roads or paths. A 2000 W motor with 50 mph top speed places this vehicle outside standard e-bike classifications in most areas.
- Bed in the brake pads with 10-15 progressive stops during the first few rides before riding at full speed or with a passenger.
- Do not ride through water deep enough to reach the motor or battery compartments.
- Charge only with the supplied chargers, indoors, at room temperature, on a non-flammable surface. Do not leave a charging battery unattended overnight.
- Do not attempt to open, puncture, or modify the battery packs. Damaged lithium packs can vent and ignite.
- Reduce speed substantially on loose, wet, or downhill grades; street tires add grip but do not eliminate the risk of losing traction.
