Features and Construction

Every component of this e-bike is chosen for practical off-road and commuting use. The hydraulic suspension fork smooths bumpy trails, and mechanical disc brakes deliver consistent stopping power. The hidden IP54 battery is secured within the frame for protection against water and dust.
Powerful Motor System
The 1000W brushless gear hub motor generates 85Nm of torque, enabling climbs on gradients up to 35 degrees. This motor suits daily commuting, hunting trips, beach fishing, or mountain trail riding without excessive strain.
Battery and Range
The 48V 15Ah waterproof lithium-ion battery is concealed in the frame and fully charges in 8-9 hours. In pure electric mode you can cover 25+ miles; in pedal assist mode the range extends to 75 miles. The battery management system prolongs cell life.
Shimano 7-Speed Gearing
The Shimano 7-speed rear hub gear lets you shift quickly between ratios, making it easy to adapt from urban streets to steep mountain paths. Combined with the 4.0 inch fat tyres, gear changes remain smooth across uneven ground.
Uses and Placement

This fat tyre electric bike is built for multiple environments. Its puncture-resistant tyres and front suspension make it suitable for both recreational trail riding and daily commuting. The four riding modes allow the rider to choose between full electric assistance, pedal assist, cart mode, or classic bicycle mode.
Trail and Off-Road Riding
The 4.0 inch wide tyres provide strong grip on loose surfaces such as gravel, sand, or snow. The hydraulic fork with lockout reduces fatigue during long bumpy rides, while the 85Nm torque helps ascend hills without losing momentum.
Commuting and Urban Use
For commuters, the bike offers a 25+ mph top speed and a Shimano 7-speed gear system for navigating city traffic. The bright LED headlight improves visibility during early morning or evening rides, and the LCD display shows real-time speed and remaining battery.
Recreational and Long-Distance Excursions
With up to 75 miles in PAS mode, this e-bike suits day trips, camping, or fishing expeditions. The 330 lbs payload capacity allows carrying additional gear, and the battery can be recharged overnight for next-day use.
Benefits and Buying Value

The SIVROCK V1 comes 85% pre-assembled, so you can complete setup in 15-30 minutes using the included tool kit and video guidance. The one-year warranty on the battery, motor, and controller provides peace of mind, and lifetime technical support is available.
Reuse and Low Maintenance
The aluminium frame resists deformation, and the puncture-resistant tyres reduce the frequency of flat repairs. The mechanical disc brakes are adjustable and reliable in wet or loose conditions. With regular care, the bike remains rideable through many seasons.
