Frame, Motor and Deck

A high-torque 800W rear-drive motor delivers swift acceleration and dependable hill-climbing, with an optimized controller that minimizes lag.

The 48V 15.6Ah pack stores 748 watt-hours, the energy behind the 28-mile range. The management system balances cells and guards against overdraw.

Up to 28 mi (45 km) on one charge covers a commute plus a detour. Rider and cargo weight, terrain, and temperature all move the number.

• Motor: 800W rear-wheel drive
• Battery: 48V 15.6Ah / 748Wh
• Range per Charge: 28 mi (45 km)
• Top Speed: 28 mph (45 km/h)
• Speed Modes: Eco 9 / Standard 19 / Sport 28 mph
• Gradeability: 20°

A governed 28 mph (45 km/h) top speed, with three modes - Eco (9 mph), Standard (19 mph), and Sport (28 mph). The motor handles grades up to 20 degrees (about a 36% slope), so urban overpasses and park paths feel effortless.

Battery, Range and Charging

The 800W rear-drive motor and a low deck make the ride feel planted the moment both feet land.

The dual suspension filters out broken pavement, and the 748Wh pack keeps the glide going. The high-torque 800W rear-drive motor delivers swift acceleration and dependable hill-climbing with minimal lag.

The aluminum frame keeps weight down to about 40 pounds for stairs and trunk loading. The finish shrugs off daily scuffs.

Plug into any standard outlet and the 748Wh pack is full in about 4 to 5 hours. A full charge costs pennies. The frame folds in seconds, so storage stays an everyday habit rather than a chore.

Who It Fits and How It Rides

Ten minutes a month keeps the 28-mile range where it belongs. Wipe the deck and stem with a damp cloth after wet rides - no pressure washer, ever.

Solvents dull the finish; water is enough. Check the folding latch is fully locked before every ride. A loose latch clicks under load - lock it and the noise disappears.

• The front fork and rear shock absorb vibrations from cobblestones
• Front and rear mechanical disc brakes keep stops short and predictable
• At about 40 pounds (18 kg) the aluminum frame folds in seconds and carries easily up
• Arrives mostly assembled - torque-check the stem and charge first

What's in the Box

HKM-M4X ships in one carton with the the product and the parts listed above. Check each item against the list before the first use, and keep the carton for the first month in case something has to go back.

Color and Finish

The 48V 15.6Ah pack holds 748 watt-hours and fills in about 4 to 5 hours on the included charger, so a mid-day top-up covers the ride home.

The management system balances cells and guards against over-current and over-discharge.

Battery Care and Maintenance

Real-world range runs up to 28 miles depending on rider and cargo weight, terrain, and temperature, and cold weather trims capacity until the pack warms.

Charge soon after a ride, store it indoors at room temperature, and keep the charge-port cover closed. Confirm the battery is charged and the system is powered on, then check all connectors are seated.

A connector left half-seated is a common no-power cause. Check the tires for cuts and embedded debris first. After that, a sudden range drop usually points to the battery or terrain.

Check the pad and rotor condition; if the lever still reaches the bar, have the circuit serviced. Wet performance is the true test of any brake system.
