Air Free Honeycomb Tires on a 30.8 lb Aerospace Aluminum FrameFeatherweight Folder for Weekdays

The A3 pairs a 350W brushless rear-hub motor with a 36V 8Ah pack for up to 21.7 miles of range per charge and a governed 15.5 mph top speed. At 30.8 pounds the aerospace aluminum frame lifts with one hand, folds in one step and carries up to 220 pounds of rider and cargo. Eight-inch air-free honeycomb tires never need a pump and shrug off punctures, while front electronic and rear disc brakes keep stops short and straight.

The A3 is the featherweight of the line, built for riders who fold and carry every day. A 350W brushless DC motor in the rear wheel delivers smooth, quiet assist, and the throttle response stays progressive so takeoffs are predictable in traffic. The 6061-T6 aerospace aluminum frame keeps the net weight at 30.8 pounds and the corrosion resistance high, and the one-step folding latch locks with a click for trunk storage and closet parking.

Range and speed stay honest. The 288Wh pack returns up to 21.7 miles per charge, and rider and cargo weight, terrain and temperature all move that number. A governed 15.5 mph top speed keeps the pace legal in city lanes and subject to local rules, and the 30-degree gradeability pulls the short ramps on the commute without drama.

Frame, Motor and Deck

The frame is 6061-T6 aerospace aluminum in White, strong for its weight and resistant to corrosion over seasons of daily use. The one-step folding latch sits at the stem base and locks with a click, so the deck folds flat in seconds for carrying upstairs.

A 350W brushless DC rear-hub motor drives the deck with quiet, progressive assist - smooth from a standstill and predictable in traffic. Top speed is a governed 15.5 mph, and a 30-degree gradeability keeps short ramps and bridge approaches on schedule.

Eight-inch solid honeycomb tires are air free and puncture resistant - no pump, no flat fixes on the shoulder of the road. Front electronic braking works with the motor for clean speed scrub, and a rear disc adds mechanical bite, so stops end short and straight.

• Motor: 350W brushless DC rear-hub with progressive throttle
• Tires: 8-inch solid honeycomb, air free and puncture resistant
• Brakes: Front electronic plus rear disc

• Gradeability: 30-degree incline
• Fold: One-step mechanism, latch clicks shut
• Load: 220 lb (100 kg) rider and cargo

The LCD dash sits at the bar center and reads speed, mode and battery at a glance, with riding modes under a thumb and cruise control for the open stretch. A 3W LED headlight lights the early and late ride and a rear brake light signals the stop.

Battery, Range and Charging

The 36V 8Ah lithium-ion pack stores 288 watt-hours in a 10S3P layout, the energy behind the 21.7-mile range. The management system balances cells and guards against over-current and over-discharge, so the pack holds up over seasons of daily use. Rider and cargo weight, terrain and temperature all move the range figure, and cold weather trims capacity until the pack warms.

Plug into any standard wall outlet and the pack fills in 3.5 to 4.5 hours on the supplied charger - no disassembly, no special equipment, and a full charge costs pennies. The charge port keeps its cover closed against dust and road spray. Store the scooter indoors at room temperature, top it up before a long weekend away, and avoid parking it warm and full right after a hard ride.

Ride the low mode for the longest distance or open it up when the road does; the LCD dash shows mode, speed and battery as you go. Cruise control holds the pace on the long straight and eases the thumb. The pack is sized for the weekly loop of short trips - errands, the last mile and the commute - without a plug midweek.

Who It Fits and How It Rides

It fits the rider who folds and carries every day. The deck carries up to 220 pounds of rider and cargo, the one-touch fold takes seconds for trunk storage and closet parking, and at 30.8 pounds the build lifts without a fight up a stairwell.

On the road it rides composed. The low, stable deck keeps the rider planted, the progressive throttle keeps takeoffs smooth in traffic, and the front electronic and rear disc brakes end stops where intended.

• Daily commutes and last-mile runs where 21.7 mi covers the loop
• Trunk, closet and under-desk parking at 30.8 lb with the one-step fold
• Riders up to 220 lb who want one light scooter for the week
• City lanes and bike paths at a governed 15.5 mph, local rules apply
• Rides in light rain, sealed to IPX4 - not for soaking or pressure washing

What's in the Box

Before the first ride: check the folding latch is fully locked, confirm both brakes bite, and charge the pack fully. HKM-A3 ships in one carton with the product and the parts listed above - check each item against this list before the first use.

Color and Finish

White covers the frame, the deck and both fenders, with a clean matte read rather than a gloss coat. The finish hides road film better than a bright lacquer after a winter of commuting, and the 6061-T6 aluminum under it stays corrosion resistant through seasons of daily use.

The deck pad is dark and textured for grip in the wet, and the LCD sits in a dark bezel at the bar center. The honeycomb tires read as a clean perforated sidewall. Wipe the finish with a damp cloth; solvents dull it.

Battery Care and Maintenance

Charge soon after a ride rather than parking it warm and full, store the pack indoors at room temperature, and keep the charge-port cover closed so dust and moisture stay out. 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, check the honeycomb tires for embedded debris, and skip the pressure washer.

Confirm the folding latch is locked before every ride - a loose latch clicks under load and the noise disappears once it is locked. Check the rear disc pad condition, and if the lever still reaches the bar, have the circuit serviced. Tighten the stem clamp and latch with a quarter turn when they creak.
