HKM-1620563 29 in Hardtail Mid-Drive Electric Mountain Bike, 250 W Mid Motor, 48 V 13 Ah Removable Battery, 25 mph Top Speed
HKM-1620563
250 W 25 mph Hardtail Mid-Drive Electric Mountain Bike
The HKM-1620563 is built around a 29 in wheel size and a hardtail aluminum frame. The big wheel rolls smoothly over broken pavement, gravel, and roots, while the hardtail design keeps the rear of the bike light, efficient, and easy to maintain.
Key Features
8 details that make the HKM-1620563 a dependable ride.
250 W Brushless Mid-Drive Motor
The brushless mid-drive motor is mounted at the bottom bracket and drives the cranks directly. Up to 56 N.m of torque is multiplied through the 7-speed Shimano cassette for natural pedal feel and confident hill climbing up to 30 degrees. The centered low weight keeps the bike balanced and predictable on climbs and technical descents.
Removable 48 V 13 Ah Lithium Battery (624 Wh)
The 48 V 13 Ah pack locks into the down tube with a key and slides out for off-bike charging. Rated for 1000+ charge cycles, the pack delivers 37 to 50 mi (60-80 km) of assisted range on a full charge. IPX5 water resistance means steady rain and shallow puddles are not a problem.
Air Suspension Fork with Handlebar Lockout
An aluminum-crown air-sprung fork with adjustable preload and a handlebar-mounted lockout lever smooths out rough roads and trails. Lockout is one click away for efficient climbing on smooth surfaces. Travel is tuned for mixed on-road and light off-road use.
Hydraulic Disc Brakes
Hydraulic disc brakes with 160 mm rotors deliver precise, modulated stopping power in wet or dry conditions. The hydraulic levers feel firm and progressive. Motor cut-off levers cut motor drive the instant either lever is pulled.
7-Speed Cassette Drivetrain
A 7-Speed Shimano cassette paired with an index shifter provides reliable, accurate gear changes across flat roads, rolling terrain, and short climbs. The mid-drive motor multiplies input through the cassette, so the gear range is wide enough for efficient cruising and steep grades alike.
Backlit Color LCD Display (c600e)
The center-mounted C600E color display shows speed, battery state of charge, pedal-assist mode, odometer, trip distance, and headlight status at a glance. The screen is backlit and readable in direct sunlight and at dusk.
Integrated LED Headlight
A bright LED headlight is handlebar-mounted and powered directly from the main battery. There are no separate cells to keep charged. The headlight is toggled from the control pad on the handlebar and stays on as long as the system is powered.
Aluminum Rear Cargo Rack
The welded aluminum rear rack is rated to carry groceries, panniers, or a tail bag, making the HKM-1620563 a true commuter-grade electric mountain bike.
Overview
Built for the ride ahead.
The HKM-1620563 is built around a 29 in wheel size and a hardtail aluminum frame. The big wheel rolls smoothly over broken pavement, gravel, and roots, while the hardtail design keeps the rear of the bike light, efficient, and easy to maintain. Up front, an air suspension fork with lockout absorbs the bigger hits when you leave the pavement and firms up for efficient climbing on smooth surfaces. The 250 W brushless mid-drive motor sits at the bottom bracket and drives the cranks directly. This is the same layout used on high-end European e-MTBs: pedal feel stays natural, weight is centered low on the frame, and the motor takes advantage of the 7-Speed cassette to climb steep hills with up to 56 N.m of torque. Top speed on pedal assist is 25 mph (40 km/h); walk-assist helps when pushing the bike up a hill or into a rack. A removable 48 V 13 Ah lithium pack stores 624 Wh - enough for 37 to 50 mi (60-80 km) of real-world range depending on how much you pedal, rider and cargo weight, terrain, and weather.
Confident, Even Disc Brakes
Disc brakes give the HKM-1620563 a confident, even stop in the wet and the dry.
Designed so the only thing you steer is your own route. We would rather over-build what you cannot see than under-deliver what you can. The HKM-1620563 pairs a 250 W brushless mid-drive, bottom-bracket mounted, 56 N.m peak torque, 48 V 13 Ah lithium-ion (624 Wh), integrated in down tube, removable and lockable, a range of 37-50 mi (60-80 km), varies with terrain, rider weight, and assist level, 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 37-50 mi (60-80 km) per charge.
The 48 V 13 Ah pack stores 624 Wh of energy. That is enough for a work week of short commutes between charges, or a full weekend of mixed trail riding. The pack locks into the down tube with a key and slides out in a few seconds for off-bike charging. Real-world range depends on how much you pedal, rider and cargo weight, tire pressure, terrain, and weather. Pedal-assist at moderate levels on flat pavement lands in the 40-50 mi (65-80 km) band. Higher assist levels, hills, headwinds, and a heavier rider bring range down toward 30-37 mi (50-60 km). Cold weather below 40 F (4 C) temporarily reduces available capacity by 10-20 percent; it returns once the pack warms up.
Daily Use & Care
A short routine keeps the ride quiet and the range where it should be.
Inflate tires to 40-50 psi (front and rear) before every ride. Properly inflated tires extend range, improve comfort, and reduce puncture risk.
Rinse the frame, rims, and drivetrain with fresh water after riding on salted roads or wet gravel. Road film attacks aluminum fasteners over time if left in place.
Lock the front fork out for road riding to save energy. Unlock it for trail or rough pavement. The handlebar lockout lever is one click.
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. Hydraulic pads give consistent feel through their life; replace when friction material is under 1.5 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.

Frequently Asked Questions
Quick answers about the HKM-1620563.
How fast does the HKM-1620563 go?
On the highest pedal-assist level, the 250 W mid-drive motor assists up to 25 mph (40 km/h). With no pedal input, the walk-assist feature moves the bike at walking pace. Because this configuration is built around EN 15194 road-legal compliance, there is no twist-throttle-only mode.
How far can I ride on a single charge?
In light pedal-assist mode on flat terrain, expect up to 50 mi (80 km). At full assist, on hills, or with a heavier rider, expect 30-40 mi (50-65 km). Cold weather also reduces range.
Is the battery removable for indoor charging?
Yes. The 48 V 13 Ah pack locks into the down tube with a key and slides out for charging in your home or office. It weighs about 7 lb (3.2 kg) and uses a standard 54.6 V 3 A charger (full charge in 4-6 hours).
Can I ride in the rain?
Yes. The HKM-1620563 has an IPX5-rated battery, motor, and wiring harness, so steady rain and shallow puddles are fine. Do not submerge the bike or use a pressure washer to clean it.
Does the bike come assembled?
The bike arrives about 90 percent assembled. You will need to install the front wheel, handlebar, pedals, and headlight bracket using the included tool kit. Allow 30-45 minutes for first-time setup, or have a local bike shop finish the build.
How is a mid-drive motor different from a hub motor?
A mid-drive motor sits at the bottom bracket and drives the cranks, so it takes advantage of the bicycle gears. The result is more efficient climbing, more natural pedal feel, and better weight distribution. A hub motor is simpler but less efficient on hills and rougher terrain.
Quick Troubleshooting
Common issues and what to check first.
Bike Will Not Power On
Confirm the battery is fully seated in the down tube and the key is turned to the lock position. Press and hold the power button on the battery for 3 seconds. Check the four-LED fuel gauge; if all four LEDs are dark, charge the battery.
Display Shows an Error Code
Power the system off, wait 10 seconds, and power on again. If the error code returns, record the code number and contact HKM support with the error number and recent riding conditions.
Brake Lever Pulls to the Handlebar
Hydraulic brakes need fluid and a periodic bleed. Do not ride. Take the bike to a certified e-bike mechanic for a hydraulic brake service.
Reduced Range or Power
Check tire pressure first: low pressure dramatically reduces range. Confirm the battery is at room temperature; cold cells deliver less energy. Inspect the brake levers - if they rub the rotor, the motor is working against the brakes. Try a lower assist level for the next ride.

Pre-Ride Safety Checklist
Run through these before every ride.
Inspect tire pressure: inflate to 40-50 psi front and rear before every ride. Properly inflated tires extend range, improve comfort, and reduce puncture risk.
Test both brakes: squeeze each brake lever and confirm the bike holds firm against pushing. Hydraulic levers should feel firm; if a lever pulls to the handlebar, do not ride and service the brake.
Confirm battery charge: press the power button on the battery to check the four-LED fuel gauge. Charge to at least three lit LEDs (about 75 percent) before heading out for a long ride.
Test lights: toggle the LED headlight with the handlebar control and confirm the brake light works. These features improve visibility and are required for road use.
Check tire tread and fasteners: look the tires over for cuts or embedded debris, and confirm the handlebar, stem, and wheel quick-releases are all fully tightened before riding.

Important Safety Notes
Read before the first ride.
This 250 W bike is rated at 25 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 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.
