A 34.2 lb Commuter With Hydraulic Damping and a 36.9 Mile Range34.2 lb Scooter Cuts Vibration 18Ah

The F5S makes lightweight commuting feel effortless. At 34.2 pounds it folds, carries, and stows without a second thought, yet still returns up to 36.9 miles on a single charge. The F5S pairs a 648Wh pack with hydraulic damping for a ride that stays composed on rough pavement and still stretches to 36.9 miles on a single charge.

The 350W rear-drive motor pulls from the back wheel for a planted takeoff, and 8-inch pneumatic tires with a puncture liner smooth out the daily grind.

Eight F5S details that make an extended-range daily rider work. A 350W brushless hub motor drives the rear wheel, so the front stays light for steering while the rear grips and pushes for a planted takeoff.

Frame, Motor and Deck

The throttle response is tuned smooth and predictable. The 36V 18Ah pack holds 648Wh on a 10S4P arrangement of 21700 cells, balancing capacity with a low center of gravity for a stable stance.

Up to 36.9 miles on a single charge, with a real-world average around 34 miles depending on rider, terrain, and temperature.

Treat the figure as a planning point. A 21.7 mph governed top speed sits in the city comfort zone - quick enough for the commute without ever feeling rushed.

Front and rear hydraulic damping absorbs 43% more vibration than spring setups, keeping the ride composed on cracked pavement and longer rides easier on the hands and feet.

Battery, Range and Charging

The 350W rear-drive motor pulls from the back wheel for a planted, predictable takeoff, 8-inch pneumatic tires with a puncture liner roll smooth over broken pavement, and a 30-degree gradeability climbs ramps without a run-up.

A 3W headlight lights the lane after dark, IP54 seals keep light rain outside, and the 6061-T6 aerospace frame keeps every gram honest.

Built to slip into the daily routine, not interrupt it. The low deck and rear-drive motor make the ride feel planted the moment both feet land.

The suspension filters out broken pavement, and the long-range pack keeps the glide going. Hydraulic damping cuts vibration by 43% versus spring suspensions, so longer rides stay easier on the hands and feet.

Who It Fits and How It Rides

Ten minutes a month keeps the 36.9-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.

• 8-inch pneumatic tires with a puncture liner roll smooth over broken pavement and shrug
• Arrives mostly assembled - torque-check the stem and charge first
• The 6061-T6 aerospace frame keeps weight down to 34.2 pounds for stairs and trunk
• The finish shrugs off daily scuffs that would mar cheaper models

What's in the Box

HKM-F5S 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 36V 18Ah pack holds 648Wh and fills to 80% in about 4.5 hours from a standard wall outlet with the included 42V/2A charger - no disassembly, no special equipment.

Real-world range runs 34.2 to 36.9 miles depending on rider and cargo weight, terrain, and temperature, and cold weather trims capacity until the pack warms.

Battery Care and Maintenance

Charge soon after a ride rather than parking it warm and full, which ages the cells faster. Store the scooter indoors at room temperature, and keep the charge-port cover closed so dust and moisture stay out of the electronics.

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 pneumatic tire pressure first - a soft tire drags and trims range. After that, a sudden range drop usually points to the battery or terrain.

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