HKM-218899 Electric Fat Tire Bike with 2000W Motor, 7-Speed Gears, and Dual Battery for Adults

HKM-218899 Electric Fat Tire Bike

Designed for adventurers who refuse to compromise, the HKM-218899 combines a high‑output 2000W motor, dual‑battery endurance, and all‑terrain capability into one refined machine. Its aluminum frame, wide 20×4″ tires, and advanced suspension deliver stability and comfort across sand, snow, gravel, or pavement. Whether you commute daily or explore off‑road trails, this e‑bike adapts to your rhythm with 7‑speed gearing, five levels of pedal assist, and an instant thumb throttle.

Motor & Drivetrain

The rear‑hub motor is engineered for sustained performance. With a continuous rating of 2000 W, it accelerates smoothly from a standstill and maintains momentum on inclines. The 7‑speed Shimano‑compatible derailleur lets you dial in the perfect cadence, while the thumb throttle offers immediate electric push without pedaling. Whether navigating stop‑and‑go city traffic or powering up a rutted trail, the HKM‑218899 responds precisely.

Dual Battery Endurance

Two high‑density lithium‑ion packs deliver a combined 31.2 Ah. This dual‑battery architecture balances weight and extends range without frequent recharging. Use throttle‑only for an estimated 62 miles (100 km); engage the 5‑level pedal assist and reach 99‑149 miles (160‑240 km), depending on terrain, rider weight, and assist level. Smart battery management protects against overcharge, over‑discharge, and temperature extremes.

• Total capacity 31.2 Ah
• Throttle range ~62 mi (100 km)
• PAS range ~99‑149 mi (160‑240 km)
• Integrated BMS protection

Torque That Conquers Hills

Generating 80‑90 Nm (59‑66 ft‑lbs) at the rear hub, the HKM‑218899 tackles steep grades and loose surfaces without hesitation. The wide power band ensures you get consistent pull even as battery voltage drops. Combined with the grippy 4‑inch fat tires, the motor translates torque into forward motion efficiently, minimizing wheel slip on gravel or wet pavement.

Suspension System

An aluminum suspension fork with 80 mm of travel paired with a double‑spring rear suspension absorbs bumps and vibrations. This dual‑suspension design keeps the tires planted for better control and reduces rider fatigue over long distances. The preload‑adjustable rear shock lets you fine‑tune stiffness based on cargo or personal preference.

20″×4″ Fat Tires & Aluminum Frame

The 20‑inch wheel diameter paired with 4‑inch wide tires provides a large contact patch for superior traction on sand, snow, and loose dirt. The lightweight 6061 aluminum alloy frame resists corrosion and keeps the overall weight manageable. Together with a low step‑through geometry (where applicable), mounting and dismounting remain easy.

Mechanical Disc Brakes & Lighting

Front and rear 160 mm mechanical disc brakes deliver strong, consistent stopping power in wet or dry conditions. Integrated LED headlight and taillight improve visibility to others and illuminate the path ahead. The lights are powered by the main battery, so you never need separate batteries.

• Front & rear mechanical discs
• 160 mm rotors
• LED headlight + taillight
• Powered by e‑bike battery

LCD Display & Ride Modes

The backlit LCD screen shows speed, battery level, assist level, trip distance, and more at a glance. Switch between five pedal‑assist levels or engage the thumb throttle for pure electric mode. The intuitive button pad places all controls within easy reach of your left thumb.
