Coil Grip and Seat Cushion over Broken Streets and Potholed LanesSaddle Springs and Four Layer Calm

The HKM-3604435 is the sit-down city folder of the line - a 500W brushless hub motor in the rear wheel, a 48V 16Ah pack worth 768Wh under the deck, and a removable saddle that turns the daily loop into seated miles. The 4-layer shock system stacks front coils, a rear coil, a sprung seatpost and 10-inch pneumatic tires, the Smart-Do LCD reads the ride, and the frame folds down when the day is done. The bell and the kickstand come fitted from the box.

The chassis wears black over 10-inch pneumatic tires with a thick rubber pad across the deck. A removable saddle sits on a sprung quick-release seatpost, the 4-layer shock system filters broken streets, and the Smart-Do LCD at the bars reads gear, riding data, power and cruise control. Front and rear mechanical disc brakes pull at the levers, the LED headlight and the metal side light strip carry the dusk, and the reflective stickers answer the traffic. The frame folds down in five steps.

Numbers stay honest. The 768Wh pack returns 45 to 55 kilometers per charge - 28 to 34 miles - the maker rates the top speed at 20 km/h, which is 12 mph, and rider weight, terrain and the gear you hold all move the figure. A full charge takes 6 to 8 hours, and the 264-pound load rating covers rider and bag together.

Frame, Motor and Deck

The 500W brushless hub motor sits in the rear wheel and pulls the seated machine cleanly away from the lights. The vector drive keeps the torque steady on the climb, the maker rates gradeability at 20 degrees, and the Smart-Do LCD shows the gear you hold at a glance.

The 48V 16Ah lithium pack is worth 768Wh and lives in the deck under the rubber pad, managed by a BMS that watches every cell. The maker's battery graphic states 45 to 55 km per charge, and the standard charger refills the pack in 6 to 8 hours.

The 4-layer shock system stacks front coil springs, a rear coil spring, a sprung seatpost and the air volume of the 10-inch pneumatic tires, so broken streets arrive softened. The tires grip damp asphalt, and the thick rubber deck pad keeps both feet planted.

Front and rear mechanical disc brakes pull at the levers, and the Smart-Do LCD reads gear, riding data, power and cruise control in one place. The LED headlight, the metal side light strip and the reflective stickers finish the night kit.

Battery, Range and Charging

The maker rates the pack at 45 to 55 kilometers per charge - 28 to 34 miles - and this page quotes that band from the battery graphic. Low gear sits at the top of it and full throttle spends it fastest; hills, cold air, rider weight and stop-and-go traffic all pull the number down. Plan the longest loop with the charger waiting at the far end. The 768Wh pack with its BMS is the capacity on the maker's sheet.

A full charge takes 6 to 8 hours on the standard charger. Top the pack up after deep rides instead of running it flat, store it near half charge in a cool dry room, and keep the contacts clean at the bay. The 59.5-pound build lifts into a trunk with two hands at the stem and the deck, and the folded frame slides under a desk. The five-step fold with its quick latches keeps the package compact between rides.

The 768Wh cells are managed by a racing-grade BMS that balances the pack and cuts off on over-current. The operating window runs 0 to 45°C in use and -10 to 40°C in storage, so bring the pack indoors on the freezing nights and let it cool before the next charge. A healthy pack is a low-cost range upgrade on its own.

Who It Fits and How It Rides

The HKM-3604435 fits the adult rider, 18 and up, who wants seated comfort on the daily loop. The 264-pound load rating covers rider and bag, the 4-layer shock system keeps the wrists and the spine fresh, and the compact fold disappears into a trunk or an office corner.

It rides best on city streets, bike lanes and broken pavement where the seat earns its keep. Fold the frame down at the end of the trip, lift the machine by the bars into a trunk, and let the rotors cool before the next descent.

• Seated commutes where the 4-layer shock system filters the broken streets
• City streets and bike lanes on 10-inch pneumatic tires
• Weekday loops measured to the rated 45 to 55 km with the charger waiting
• Compact folding for trunks, trains and office corners
• Night rides on the LED headlight, side light strip and reflective stickers

What's in the Box

Before the first ride: match the parts against the list, fit the saddle, check the folding latches lock with a firm click, test both disc brakes at walking pace, and charge the pack to full. Every item above ships in one carton - follow the manual for setup, folding and charging in English.

Colors and Finish

Black covers the frame, the stem and the deck, and the red calipers and the blue side light strip give the build its edge. The finish reads clean in daylight and shows city dust honestly at the fenders. The reflective stickers on the frame add a little more of the same at night.

The folded package keeps the paint inboard, the rear fender takes the spray off the back, and the thick rubber pad leaves room for both feet.

Battery Care and Maintenance

Treat the 768Wh 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 at the bay. The 6 to 8 hour refill is the routine - 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 latches clean and locked before every ride, check pressure in the 10-inch pneumatic tires weekly, confirm both disc rotors still bite at walking pace, re-torque the axle bolts after the first fifty miles, and keep the seatpost clamp tight. The tool kit in the box covers the stem latch and the seatpost, and the quick-release clamp sets saddle height in seconds.
