Regenerative Rear Braking and a Mechanical Disc Up Front500W Hydraulic Damping 43.2 lb 8 in

The F7S pairs a 500W rear-drive motor with a 48V 24Ah pack for up to 47.8 miles per charge, then smooths the whole ride over a patented hydraulic suspension that cuts road vibration by 40%. The F7S is the long-range commuter built around a single idea: distance should not cost you comfort.

Roll out with a full 48V 24Ah pack and 47.8 miles of range is on the table, enough to leave the charge cable at home for the whole work week.

A front mechanical disc brake and rear electronic regenerative braking share stopping duty, 8-inch solid tires shrug off flats, and the 6061-T6 frame keeps the full package down to 43.2 pounds.

Frame, Motor and Deck

It climbs a 30-degree grade without a run-up, folds flat in one step, and carries up to 265 pounds.

Built for the commuter who wants range and comfort in one machine, not a compromise. Eight F7S details that turn a long commute into the calmest part of the day.

A 500W brushless hub motor pushes from the back wheel, so traction stays planted when the road turns wet or uneven. The throttle map is tuned progressive and a sine-wave controller keeps the delivery quiet.

Hills and headwinds are the honest variables in any ride. The 48V 24Ah pack stores 1152 watt-hours in a 21700-cell arrangement, riding low in the deck for a stable stance.

Battery, Range and Charging

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. The 500W motor drives the rear wheel, so the front stays light for steering while the rear grips and pushes.

Weight sits balanced and takeoffs feel planted - the F7S settles into a stable ride the moment both feet land.

The hydraulic fork damps through fluid valves instead of a steel coil, so pothole edges are absorbed once and done.

Who It Fits and How It Rides

Ten minutes a month keeps the 47.8-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 management system balances cells and guards against overdraw
• Up to 40% less vibration reaches the deck, which means less fatigue on a long commute
• The 6061-T6 aerospace frame keeps weight down to 43.2 pounds for stairs and trunk
• The finish shrugs off daily scuffs that would mar cheaper models

What's in the Box

HKM-F7S 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 24Ah pack holds 1152 watt-hours and fills from empty in about 5.5 to 6.5 hours on the included 54.6V fast charger. The management system pushes harder through the 0–80% phase, then tapers the final 20% to protect the cells, so a mid-day top-up covers much of the ride home.

Real-world range runs 47.8 to 52.9 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, store it 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 solid tires for cuts and embedded debris first - they are air-free, so flats are not the issue. A sudden range drop usually points to the battery or terrain.

Check the disc 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.
