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 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.

Eight A3 Eco details that make a featherweight daily rider work. A 350W rear-hub motor drives the deck with smooth, quiet assist.

Frame, Motor and Deck

The throttle response is tuned progressive, so takeoffs stay smooth and predictable.

Hills and headwinds are the honest variables in any ride. 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. Up to 21.7 mi (35 km) on one charge covers the week’s short trips without a plug.

• Motor: 350W brushless DC rear-hub motor
• Battery: 36V 8Ah lithium-ion / 288Wh (10S3P)
• Range per Charge: 21.7 mi (35 km)
• Top Speed: 15.5 mph (25 km/h), electronically governed
• Frame: 6061-T6 aerospace aluminum
• Wheels: 8-inch solid honeycomb

Hills and headwinds tax any vehicle, so treat the figure as a planning point. Plan routes around the charge, not against it. The 15.5 mph governed pace sits in the city-lane comfort zone, so the ride never feels rushed.

Battery, Range and Charging

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.

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.

Who It Fits and How It Rides

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.

• The braking profile favors control over drama, and stops end where intended
• Wet roads still ask for gentler inputs everywhere
• 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

What's in the Box

HKM-A3 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

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.

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 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.

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.
