Stable Three Wheel Commutes with Padded Support and a Quick FoldA Seat with the Backrest That Folds

The HKM-3216979 is the seated three-wheel folder of the line - a 250W brushless hub motor, a 36V 7.8Ah pack rated at 280.8Wh, and an enlarged padded seat with a supportive backrest that turns the errand loop into a sitting job. Three wheels hold steady, the frame folds in about three seconds, and the folded unit pulls like luggage. Every figure comes from the maker's spec sheet and the pictured hardware - up to 18.6 miles per charge, 15 mph governed top speed, and a 220.4-pound load rating.

The chassis is a three-wheel aluminum frame finished in white with black grips, saddle and fenders over 10-inch pneumatic tires. An enlarged padded seat carries a supportive backrest, the seat post rides a coil spring that softens broken pavement, and a white basket bolts ahead of the stem. The handlebar display reads speed, trip and battery status, and a headlight sits above the fork. Folded, the frame measures 17.33 by 22.83 by 34.64 inches and drags like luggage.

Numbers stay honest. The 280.8Wh pack returns 15.5 to 18.6 miles per charge, the governed top speed lands at 15 mph, and three forward gears cap the pace at 3, 7 and 15 mph with a controlled 2 mph reverse. Rider weight, terrain, temperature and the gear you hold all move those figures, so plan the long loop with a charger waiting at the end of it.

Frame, Motor and Deck

The three-wheel platform is the point: one wheel steers ahead, two hold the rear axle wide, and the deck keeps the rider centered. The quick-folding frame drops the stem at the latch - about three seconds from riding to rolling - and the folded package fits a trunk or a closet.

A 250W brushless hub motor sits in the front wheel, rated at 1300 rpm with 13 N·m of output torque and a dual-mode brushless controller behind it. Key ignition starts the machine, and three forward gears let the motor work below its cap whenever the crowd asks for patience.

The enlarged padded seat is built for the long way, and the backrest takes weight off the lower back. The seat post rides a coil spring that softens the sharp edges, a white basket bolts ahead of the stem, and a headlight above the fork lights the way after dark.

• Motor: 250W brushless hub, rated 1300 rpm
• Battery: 36V 7.8Ah / 280.8Wh lithium
• Tires: 10 in (25.4 cm) pneumatic, front and rear
• Brake: Front power drum brake
• Seat: Enlarged padded seat with backrest
• Frame: Three-wheel folding frame, 17.71 in (45 cm) rear axle
• Display: Speed, trip distance and battery status
• Ignition: Key ignition with battery lock

Ten-inch pneumatic tires roll front and rear, soaking the chatter, and a front power drum brake handles the stops from the grip. The display keeps speed, trip and battery status in view, and the key at the deck doubles as the battery lock.

Battery, Range and Charging

The 36V 7.8Ah lithium pack is rated at 280.8Wh and lifts out of the frame under a physical key lock - carry the battery to the apartment and leave the frame in the garage, or charge it in place with the standard charger. A full charge takes about four hours, and the pack is listed for up to five years and more than 600 charge cycles when it is treated well. The maker rates 15.5 to 18.6 miles (25 to 30 km) per charge from it.

The maker's band runs 15.53 to 18.64 miles (25 to 30 km) per charge, and this page rounds it to 15.5 to 18.6 miles. Rider weight, the gear you hold, hills, cold air, tire pressure and stop-and-go traffic all move the number - a light rider on flat pavement in the low gear sees the top of the band, while the loaded climb in the high gear sees the bottom. Plan the longest weekday loop with the charger waiting at the far end.

Top the pack up after deep rides instead of running it flat, store it around half charge in a cool dry room, and keep the contacts clean at the lock. For travel, the removable design makes planning easier - a 94Wh battery can be ordered separately when a carrier asks for a pack under 100Wh.

Who It Fits and How It Rides

The HKM-3216979 fits the adult who wants stable seated mobility - errands, campus loops, short commutes and the slow ride home - without balancing a deck under the feet. The 220.4-pound load rating covers rider and cargo together, and the 8° maximum incline covers the driveway and the standard ramp.

It rides best on pavement and bike lanes. The controlled reverse walks it out of a tight spot at about 2 mph, and when the trip ends the frame folds in seconds and pulls like a piece of luggage.

• Stable seated errands across town and back
• Three forward gears for sidewalks, bike lanes and long straights
• Controlled reverse for tight parking spots and hallways
• Folds in seconds and rolls like luggage for trains and trunks
• Keyed ignition and headlight for the ride home after dark

What's in the Box

Before the first ride: install the rear axle, check the folding latch locks with a firm click, cycle the gears and the reverse at walking pace, and charge the pack to full. Every item above ships in one carton - match the parts against the list and follow the manual in English.

Colors and Finish

White covers the frame, the stem and the basket, and the finish keeps the machine looking clean against black grips, a black saddle and black fenders. The two-tone look reads light in a hallway and shows dirt honestly at the wheels. The maker lists this build in white with a black seat.

The padded seat and backrest are black against the white frame. The folded package keeps the paint inboard in a trunk. Wipe the frame with a damp cloth.

Battery Care and Maintenance

Treat the 280.8Wh pack as the machine's heart. Charge it after deep rides instead of running flat, store it near half charge in a cool dry room, and keep the contacts clean. About four hours brings it to full - unplug when the light says done, and never charge a pack that feels hot, swollen or wet.

The moving parts ask for a small routine: keep the folding latch clean and locked before every ride, check tire pressure on the 10-inch pneumatics weekly, confirm the front drum brake still bites at walking pace, and re-torque the rear axle bolts after the first fifty miles. The seat post spring and the hinge appreciate a wipe when the season turns wet. The tool kit in the box covers the rear axle and the folding latch.
