HKM-989523 48V 16.7Ah Electric Fat Tire Bike
Unleash unstoppable exploration with a fusion of rugged durability and smart electric performance.
Engineered for those who demand both urban agility and trail-conquering confidence, the HKM-989523 merges a high-torque 250W rear hub motor with a massive 48V 16.7Ah lithium battery, fat 20″×4.0″ tires, and a precise 7-speed drivetrain. Its robust steel frame absorbs vibrations while maintaining sharp handling, and the customizable color/logos let you ride a bike that truly reflects your personality. From potholed city streets to loose gravel paths, every journey becomes a statement of freedom.
Endurance Battery System
The heart of the HKM-989523 is a state-of-the-art 48V 16.7Ah lithium-ion pack, carefully assembled with automotive-grade 21700 cells. With a total energy of 798.4 watt-hours, you can cover up to 37 miles (60 km) on a single charge in ideal conditions—ample for most daily commutes and weekend explorations. The smart Battery Management System (BMS) safeguards against overcharge, over-discharge, and temperature extremes, ensuring longevity. The battery is lockable and quickly removable, so you can charge it indoors or swap in a spare. Charging from empty takes approximately 5–7 hours with the included 2A smart charger.
Dynamic Rear Hub Motor
The 250W brushless geared hub motor provides a smooth and intuitive pedal-assist experience. It delivers up to 45 newton-meters of torque, letting you tackle 15% gradients without breaking a sweat. The motor’s internal gearing reduces resistance when riding unassisted, so you can pedal naturally even without power. Five levels of pedal assist let you fine-tune the effort, and a walk-assist mode (4 km/h / 2.5 mph) helps you push the bike up stairs or steep ramps. Speed is electronically governed to 15.5 mph (25 km/h) in compliance with EU regulations; region-specific configurations may allow higher limits where legally permitted.
All-Terrain Fat Tires & Steel Frame
The 20-inch wheels wrapped in 4.0-inch wide tires create a massive contact patch, effectively absorbing road vibrations and improving traction on loose surfaces. Whether you're rolling over cobblestone alleys or hard-packed dirt, the low-pressure capability (5–30 PSI) lets you adjust for plush comfort or efficiency. The high-tensile steel frame offers natural flex and impact resistance, while the rigid fork keeps weight manageable. This combination results in a ride that feels planted yet lively. The step-over frame geometry accommodates a wide range of rider heights, typically from 5'3" to 6'4" (160–193 cm).
Precision Drivetrain & Braking
The 7-speed rear derailleur and thumb shifter offer crisp gear transitions, allowing you to maintain an optimal cadence whether accelerating from a stoplight or climbing forest trails. The gearing range pairs well with the motor's assist, ensuring you never feel over-geared. Stopping power comes from front and rear mechanical disc brakes with 160mm rotors. The brake levers include motor cutoff sensors, instantly disengaging power when you squeeze, for added safety. The system is designed for low maintenance and easy pad replacement.
Customization & Connected Cockpit
Express your style with personalized frame colors and logo options—choose from a curated palette or provide your own brand identity. The backlit LCD console is positioned centrally, showing real-time speed, trip distance, odometer, battery charge percentage, and assist level. It's designed to be readable in direct sunlight and automatically dims at dusk. A USB port on the display allows you to charge your phone or GPS device on the go, keeping you connected throughout your ride.

Why Choose the HKM-989523
Frequently Asked Questions
How long does the battery really last on a single charge?
Range varies based on rider weight, terrain, assist level, and weather. In optimal conditions (flat ground, pedal-assist level 2, 165 lb rider), you can expect up to 37 miles (60 km). Aggressive throttle use or steep hills may reduce range to around 19 miles (31 km). The LCD display provides an accurate real-time battery percentage so you're never caught off guard.
Can I ride it in the rain or through puddles?
Yes, the electrical components are rated IP54 for water resistance, meaning they can handle splashes and light rain. However, we recommend avoiding submerging the battery or motor in water. Always dry the bike after wet rides to prolong component life.
What is the recommended rider height and weight?
The step-over frame fits riders approximately 5'3" to 6'4" (160–193 cm). The maximum payload capacity is 265 lbs (120 kg), including rider and cargo. The wide tires and steel frame provide stable handling across this range.
Does the bike come assembled?
The HKM-989523 arrives 85% pre-assembled. You'll need to attach the front wheel, handlebar, pedals, and seat. Tools and an illustrated manual are included. Most riders complete assembly in 20–30 minutes.
