Range varies based on several factors: rider weight, terrain type, assist level, tire pressure, ambient temperature, and wind conditions. Under moderate pedal-assist (PAS level 3) on flat terrain with a 180 lb (82 kg) rider, expect approximately 31–37 miles (50–60 km). Using throttle-only mode at maximum speed will reduce range to approximately 19–22 miles (31–35 km). Colder temperatures below 40°F (4°C) may temporarily reduce range by 10–15%.

Using the included 48V charger, a complete charge from 0% to 100% typically takes approximately 5–7 hours. The battery management system will automatically stop charging once full capacity is reached, so you can safely charge overnight.

Yes. The 4.0-inch wide fat tires are specifically designed for low-pressure operation on soft surfaces. When tire pressure is reduced to approximately 8–12 PSI, the increased contact patch provides excellent flotation on sand, snow, and loose gravel. For hard-packed surfaces, inflate to 20–25 PSI for reduced rolling resistance.

The HKM-398547 weighs approximately 65–72 lbs (29–33 kg) fully assembled with the battery installed, depending on configuration. The battery itself accounts for roughly 9–10 lbs (4–4.5 kg) of that total and can be removed for transport.

Regulations vary by jurisdiction. In most U.S. states, electric bicycles with a top assisted speed of 28 MPH (45 KM/H) or less and a motor under 750W are classified as Class 3 e-bikes and do not require a license. However, the HKM-398547 features a 1000W motor and can reach 31 MPH (50 KM/H). We recommend checking your local and state regulations regarding e-bike classification, helmet requirements, and where this model may be legally operated. Some jurisdictions may classify it differently.

Yes, the battery can be charged either while mounted on the bike or after removal. The charging port is accessible without removing the battery, making it convenient for garage or indoor charging. For security, the battery can be locked to the frame with the included key.
