HKM-A3 Eco Adult Electric Scooter 350W Motor 36V 8Ah Battery 21.7 Mile Range Honeycomb Tires LED Light Folding Frame
HKM-A3 Eco
Featherweight Electric Scooter
The A3 Eco makes lightweight commuting feel effortless. At 30.8 pounds it folds, carries, and stows without a second thought, yet still returns up to 21.7 miles on a single charge. The 350W rear-hub motor pulls from the back wheel for a planted, predictable takeoff, air-free 8-inch honeycomb tires shrug off flats for good, and a 30-degree gradeability climbs ramps without a run-up. A 3W headlight lights the lane after dark, IPX4 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 A3 Eco details that make a featherweight daily rider work.
350W Rear-Drive Motor
A 350W rear-hub motor drives the deck with smooth, quiet assist. The throttle response is tuned progressive, so takeoffs stay smooth and predictable. Hills and headwinds are the honest variables in any ride.
36V 8Ah 288Wh Battery
The 36V 8Ah 288Wh battery rides low in the deck for a stable stance. The management system balances cells and protects the pack against overdraw. Charging habits protect the pack long term.
21.7 mi Per Charge
Up to 21.7 mi (35 km) on one charge covers the week’s short trips without a plug. Hills and headwinds tax any vehicle, so treat the figure as a planning point. Plan routes around the charge, not against it.
15.5 mph City Pace
The 15.5 mph governed pace sits in the city-lane comfort zone, so the ride never feels rushed. The braking profile favors control over drama, and stops end where intended. Wet roads still ask for gentler inputs everywhere.
30.8 lb Featherweight Frame
At 30.8 lb the 6061-T6 frame folds for stairs, trunks, and under-desk parking. Carry it by the stem with one hand while the locked deck keeps the rest compact. The folding latch is the joint that matters most.
8-inch Honeycomb Tires
8-inch honeycomb tires ride air-free, so flats and pinch leaks are off the table. The solid structure stays composed over broken pavement, and there is no pressure to check before every ride.
30 Degree Gradeability
A 30-degree gradeability carries the A3 Eco up ramps and bridges without a run-up. The low, balanced deck keeps the rider planted, and the stance width suits both a relaxed cruise and an active push.
3W LED Headlight
A 3W front LED headlight and rear brake light keep the rider visible after dark. The beam is cut to light the lane without blinding oncoming riders, so visibility stays a two-way street at dusk.
IPX4 Weather Protection
IPX4-rated seals on the port and battery bay keep splashes out. Ride through damp mornings and shallow puddles, then wipe it dry at home. The finish sheds water on its own.
Overview
Light enough to forget, ready when you are.
The A3 Eco earns its name at 30.8 pounds - light enough to fold, carry, and stow without a second thought, yet still returning up to 21.7 miles on a single charge. The 350W rear-hub motor pulls from the back wheel for a planted takeoff, and the 6061-T6 aerospace frame keeps every gram honest. Air-free honeycomb tires shrug off flats, a 30-degree gradeability climbs ramps without a run-up, and the 3W headlight lights the lane after dark. IPX4 seals keep light rain outside. This is a scooter built to disappear into the daily routine, not interrupt it.
Glide Light, Glide Far
30.8 lb, planted from the first push.
The 350W rear-hub motor and a low 30.8 lb deck make the ride feel planted the moment both feet land. 8-inch honeycomb tires smooth out broken pavement, and the 288Wh pack keeps the glide going for up to 21.7 miles per charge.

Battery and Charging Details
288Wh of capacity in a 30.8 lb frame, tuned for the daily ride.
The 36V 8Ah pack holds 288Wh and fills in about 3.5 to 4.5 hours from a standard wall outlet with the supplied charger - no disassembly, no special equipment. Real-world range runs 19.7 to 21.7 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 21.7-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 - a full 0-100% fill takes about 3.5 to 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 honeycomb tires are air-free, so there is no pressure to check. Just glance at the tread for cuts and embedded debris before each ride.
Check the brake pads 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 21.7-mile range before the 288Wh pack does.

Why Riders Pick the HKM-A3 Eco
Eight reasons the featherweight A3 Eco earns its daily keep.
Rear-Wheel Drive
The 350W 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 A3 Eco settles into a stable ride the moment both feet land.
6061-T6 Aerospace Frame
The 6061-T6 aerospace frame keeps weight down for stairs and trunk loading. The finish shrugs off daily scuffs that would mar cheaper models. The finish is built to be used, not babied.
3.5-Hour Fast Charge
Plug into any standard outlet and the 288Wh pack is full in about 3.5 to 4.5 hours - no all-night wait. A full charge costs pennies compared with the same trip by car.
Folds in Seconds
The 30.8 lb 6061-T6 frame folds flat in seconds, so storage stays an everyday habit rather than a chore. Folded, it slides into a trunk, a closet, or under a desk.
220 lb Load Capacity
The deck carries up to 220 lb with margin to spare. Straps hold better than hands - route them through the frame. The rating includes real-world cargo.
Simple, Reliable Controls
The thumb throttle, brake lever, and LCD stay simple enough to learn in one ride, and nothing on the deck interrupts the standing position. The 15.5 mph governed pace keeps behavior predictable.
Low-Maintenance Design
Air-free honeycomb tires never go flat, and there is no chain to oil and no air to fill. Wipe it down, keep it charged, and the A3 Eco stays ready - the whole routine takes minutes a month, not a weekend in the garage.
Ready Out of the Box
Charger, manual, and fittings ship in the box, and the whole first-ride checklist fits on a sticky note. Charge it up and the first ride starts at full.
Folds Flat, Carries Light
6061-T6 aerospace frame, seconds to stow.
The 6061-T6 aerospace frame folds flat in seconds, sliding into trunks, closets, and under desks. At 30.8 pounds it carries one-handed up stairs, and the locked deck keeps the whole package compact until the next ride calls.
Controls & Indicators
Every A3 Eco 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
One finger is all the lever asks for; the pads do the rest. 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 LCD screen. 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 A3 Eco 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 21.7 mi (35 km) per charge from the 288Wh pack. Rider and cargo weight, terrain, and temperature are the big three variables to watch.
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 seconds 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 - wipe it dry afterward, keep the charge port closed, and never soak the battery bay.
What accessories are included?
A 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 A3 Eco 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 honeycomb 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.
The brakes feel weak.
Check 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.
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
A3 Eco documented and tested for sale and transport.
CE
European Conformity (CE) marking covering the electrical assembly and charger.

Zero-Flat, Read Anywhere
8-inch honeycomb tires and a 30-degree climb.
8-inch honeycomb tires shrug off glass and debris for a zero-flat ride, while the LCD keeps speed, battery, and mode large and legible. A 30-degree gradeability climbs steep ramps, and the 3W headlight keeps the lane lit after dark.
Pre-Ride Safety Checklist
Thirty seconds of A3 Eco checks before every ride.
Inspect the tires for cuts, glass, and embedded debris. Tire tread 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 A3 Eco ride.
This HKM-A3 Eco 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.
