The HKM-3429587 is the retro-styled fat-tire electric bike built for the rider who wants Super73-style looks.

Battery and Charging Details
Power for the all-terrain loop.
The battery powers the 1500W rear-hub motor efficiently, returning 34 to 40 miles on a full charge. Charge with the included charger and store the pack at room temperature when the bike will sit. Cold weather trims capacity until the pack warms, and real-world range moves with rider weight, terrain, and assist level.
Daily Use & Care
Ten minutes a month keeps the 34-40 mile range where it belongs.
Wipe the frame, saddle, and wheels with a damp cloth after wet or muddy rides - no pressure washer, ever.
Keep the drivetrain clean and lubed. A gritty chain eats range before the pack does.
Check the fat tires weekly and keep them in the recommended pressure range. A soft tire drags and trims range.
Check the disc brake pads monthly; pads wear silently until they are gone.
Charge indoors at room temperature and unplug when the light turns green.
Keep the charge port covered between charges so moisture stays out.
Confirm the battery gauge shows the charge you expect before heading out.
Spin both wheels weekly and check that nothing rubs. A rubbing brake eats into the range.

Common HKM-3429587 issues and what to check first.
The motor does not engage.

The brakes feel weak.
Check the pad condition; if the lever still reaches the bar, have the brakes serviced.
