HKM-F5S Urban Electric Scooter 350W Motor 36V 18Ah Battery 36.9 Mile Range Hydraulic Suspension LED Light Folding Frame
HKM-F5S
Hydraulic-Comfort Scooter
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 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.
Key Features
Eight F5S details that make an extended-range daily rider work.
350W Rear-Drive Motor
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. The throttle response is tuned smooth and predictable.
648Wh Battery
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.
36.9 mi Range
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.
21.7 mph Top Speed
A 21.7 mph governed top speed sits in the city comfort zone - quick enough for the commute without ever feeling rushed.
Hydraulic Suspension
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.
8-inch Pneumatic Tires
8-inch pneumatic tires with a puncture liner roll smooth over broken pavement and shrug off the glass you cannot always dodge.
30-Degree Gradeability
A 30-degree grade-climbing capability carries the F5S up ramps and bridges without a run-up.
3W LED Headlight
A 3W front LED and a rear brake light keep you visible before sunrise and after dark.
IP54 Water Resistant
IP54-rated seals keep splashes and light rain out of the electronics and battery bay.
Overview
Hydraulic comfort by design, extended range by habit.
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. At 34.2 pounds it folds flat for the office or the closet, and IP54 seals plus a 3W headlight keep it ready for the early ride, the late ride, and the damp one in between. This scooter is built for distance, delivered with comfort.
Glide Far, Ride Smooth
Built to glide, from the first push.
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.

Battery and Charging Details
648Wh of capacity, filled in under an evening.
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. 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.
Daily Use & Care
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.
Charge indoors at room temperature and unplug when the light turns green - 0–80% takes about 4.5 hours. Dry contacts charge faster and wear slower.
Keep the charge-port cover closed between charges so moisture stays out. A closed port keeps grit and rain away.
The 8-inch pneumatic tires ride on air, so check the pressure every week and keep it in the recommended range. A soft tire drags and trims range; a hard tire rides rougher.
Check the mechanical disc and electronic brake monthly; pads wear silently until they are gone. Pads wear out; a missed stop is not.
Confirm the battery gauge shows the charge you expect before heading out. The gauge is the first diagnostic you own.
Spin both wheels weekly and check that nothing rubs. A rubbing guard eats into the 36.9-mile range before the 648Wh pack does.

Why Riders Pick the HKM-F5S
Eight reasons the extended-range F5S earns its daily keep.
43% Less Vibration
Hydraulic damping cuts vibration by 43% versus spring suspensions, so longer rides stay easier on the hands and feet.
6061-T6 Aerospace Frame
The 6061-T6 aerospace frame keeps weight down to 34.2 pounds for stairs and trunk loading. The finish shrugs off daily scuffs that would mar cheaper models.
4.5-Hour Fast Charge
A 42V/2A smart charger fills the 648Wh pack to 80% in about 4.5 hours, with auto trickle-mode to protect the cells.
Folds in Seconds
Folding takes seconds, so storage stays a habit rather than a chore. Folded, it slides into a trunk, a closet, or under a desk.
265 lb Load Capacity
The deck carries up to 265 pounds with margin to spare. Straps hold better than hands - route them through the frame.
Electronic + Disc Brakes
The front electronic brake and rear mechanical disc share stopping duty, keeping stops predictable in every condition.
Puncture-Liner Tires
8-inch pneumatic tires carry a puncture liner that rolls over glass and debris the way you cannot always dodge, without the constant flats.
IP54 Weather Protection
IP54-rated seals keep splashes and light rain out of the electronics and battery bay, so a damp morning does not end the ride.
Folds Flat, Carries Light
One step to stow, one hand to carry.
The aerospace frame folds flat in one step, sliding into trunks, closets, and under desks. It carries one-handed up stairs, and the locked deck keeps the whole package compact until the next ride calls.
Controls & Indicators
Every F5S control explained in a single line.
Throttle
Twist or thumb, the response is progressive and easy to modulate. The manual documents each control in full.
Brake Lever
The front electronic brake and rear disc lever are one finger away. All controls are reachable without taking your hands off the bars.
Power Button
Long-press to arm the system, short-press to toggle modes. Power cycle first; it clears more faults than anything else.
Charging Port
The charge point sits behind a weather cover. Try another outlet before blaming the charger or the pack.
Display
Speed, battery level, and mode stay on one LED console. Wipe the display with a dry cloth; sprays cloud the lens.
Handlebar Clamp
The clamp holds the bars at your chosen height; confirm it is tight before riding. The stem fold is the strongest joint on the scooter when properly locked.
Frequently Asked Questions
Common F5S questions, answered briefly.
How much assembly is required?
Mostly assembled: torque-check the stem and handlebars, confirm the brakes bite, and charge before the first ride. The stem bolt is the one connection you should never second-guess.
How far will it go on one charge?
Up to 36.9 mi (59 km) per charge from the 648Wh pack, with a real-world average around 34 miles. Rider and cargo weight, terrain, and temperature are the big three variables.
How fast does it go?
The pace is set for city-legal riding - confirm your local rules and regulations before riding on public paths or roads.
Is it foldable?
Yes - the deck folds in one step for carrying, trunk storage, and closet parking. Folded flat, it slides into surprisingly tight spaces.
Can it ride in the rain?
Light rain is fine - the IP54 rating keeps splashes out. Wipe it dry afterward, keep the charge port closed, and never soak the battery bay.
What accessories are included?
A 42V/2A charger, user manual, and fitting toolkit ship in the box. Everything in the box list ships in the same carton as the scooter.
Is a helmet required?
Yes, every ride - a certified helmet is inexpensive protection on any electric scooter. Head protection is the one piece of gear worth getting right.
What warranty is included?
24 Months Warranty Service, 180 Days Purchase Protection, and 30 Days Money-Back Guarantee. Warranty terms start the day the scooter ships, not the day it rides.
Quick Troubleshooting
Common F5S issues and what to check first.
The motor does not engage.
Confirm the battery is charged and the system is powered on, then check all connectors are seated. A connector left half-seated is the most common no-power cause.
Range dropped noticeably compared with when it was new.
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.
The brakes feel weak.
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.
The deck creaks over bumps.
Tighten the folding latch and stem clamp; a quarter turn usually finds it. A creak is information, not a defect.
The display or lights will not power on.
Confirm the pack has charge and all connectors are seated. Switch off, wait 30 seconds, and power on again. Power cycling is the gentlest first step.
The charger light never turns green.
Check the port cover is fully seated and try a different outlet before assuming the charger is at fault. The port cover is the smallest part with the biggest job.
Certifications & Standards
Documented and tested for sale and transport.
CE
European Conformity (CE) marking covering the electrical assembly and charger.
RoHS
Restriction of Hazardous Substances (RoHS) compliance for the electronics and cells.
UN38.3
Lithium battery transport certification for safe shipping of the pack.
MSDS
Material Safety Data Sheet documenting the lithium pack for carriers.
ISO 9001
Quality management system standard applied across the production line.
Tested Cells
Each battery batch is cycle-tested before assembly and again before shipping.
Zero-Flat, Read Anywhere
Solid tires and a clear dashboard.
Solid tires shrug off glass and debris for a zero-flat ride, while the LED display keeps speed, battery, and mode large and legible. The brakes keep stops predictable in every condition.
Pre-Ride Safety Checklist
Thirty seconds of F5S checks before every ride.
Inspect the tires for cuts, glass, and embedded debris, and check the pressure. Tire pressure is the first thing to check after a long season.
Keep the motor area clear of mud, string, and debris. The motor vent is the only place air should ever enter.
Tighten handlebar and stem hardware monthly - vibration loosens fasteners. A quarter-turn usually finds the creak.
Squeeze the brake lever hard while stationary - the deck should not creep. Wet leaves are as slick as ice.
Wear a helmet every ride and use the lights in low visibility. A certified helmet is inexpensive protection.
Listen for new creaks and rattles; they are the first sign of a loose joint. A creak is information, not a defect.
Ride a quiet street loop first and confirm clean throttle response. Power cycling clears more faults than anything else.
Check your local e-scooter rules before riding on shared paths. Rules vary by city, and they change.

Important Safety Notes
Read before the first HKM-F5S ride.
This HKM-F5S is an electric scooter rated per the spec sheet below - ride it where the law allows. Wear a helmet every ride and ride only where the law allows. Read the manual first and practice throttle and braking in an open, traffic-free area. Do not exceed the load limit marked on the deck. Slow down substantially on wet surfaces, gravel, and steep descents - braking distance grows fast. Never open, puncture, or modify the battery. Charge only with the supplied charger, indoors and attended, and unplug when full.
