1000W Brushless Rear Hub Motor

The KETELES K800 is powered by a 1000W brushless geared rear hub motor delivering approximately 60–70 Nm of torque.

The high-output electric drive provides strong assistance for:

• Daily commuting
• Hills and inclined roads
• Gravel routes
• Countryside roads
• Recreational trails
• Longer-distance journeys
• General outdoor transportation

The rear-hub configuration delivers motor power directly through the rear wheel for responsive electric-assisted riding.

48V Lithium-Ion Battery

A high-capacity 48V rechargeable lithium-ion battery supplies power to the motor and electrical components.

The down-tube battery placement keeps the power source positioned within the main bicycle frame while providing convenient access for charging and battery management.

Electric & Pedal-Assist Range

The K800 supports multiple riding styles with a listed range of:

Electric-Only Range: Approximately 35–40 km
Pedal-Assist Range: Approximately 50–60 km

Pedal assistance combines rider input with motor power, helping extend riding distance compared with continuous electric-only operation.

Range is influenced by terrain, rider weight, gradients, assistance level, speed, weather, tyre pressure and battery condition.

Shimano 21-Speed Drivetrain

The Shimano 21-speed transmission provides a broad selection of mechanical gears for changing terrain.

Lower gears assist with climbing and slower riding, while higher gears support efficient pedalling on flatter roads.

Combined with the 1000W electric motor, the drivetrain provides flexible control for both powered and pedal-assisted cycling.

26 × 4-Inch Fat Tyres

The K800 features large 26 × 4-inch fat tyres that provide a broad contact area for increased traction, stability and cushioning.

The fat-tyre configuration is suited to:

• Paved roads
• Gravel
• Countryside routes
• Recreational trails
• Beach surfaces
• Uneven outdoor paths
• Mixed-surface riding

Front Suspension Fork

The aluminum-alloy crown suspension fork helps absorb bumps and vibration encountered on uneven roads and recreational trails.

Combined with the high-volume fat tyres, the suspension system provides additional comfort and front-wheel control across changing surfaces.

Mechanical Disc Brakes with Motor Cut-Off

The KETELES K800 uses mechanical disc brakes with a motor power cut-off function.

When braking is activated, the cut-off system interrupts motor assistance, helping provide controlled deceleration during electric-assisted riding.

Smart Multifunction LCD Display

The handlebar-mounted smart LCD display provides convenient access to important riding information, including:

• Current speed
• Battery level
• Pedal-assist level
• Travel distance
• Riding status

Right-Side Twist Throttle

A right-side twist throttle provides direct control of electric motor assistance, allowing convenient electric-powered operation.

The throttle works alongside the pedal-assistance system and Shimano mechanical drivetrain to provide flexible riding options.

LED Headlight

The integrated battery-powered LED headlight provides forward illumination and improves bicycle visibility during low-light riding.

6061 Aluminum-Alloy Frame

The K800 is built around a durable 6061 aluminum-alloy frame, providing a strong structure for the high-output motor, battery and fat-tyre wheel system.

Aluminum-alloy construction also provides good corrosion resistance for regular outdoor use.

Suitable Riding Applications

The KETELES K800 is suitable for:

• Daily commuting
• Recreational cycling
• Gravel roads
• Countryside routes
• Moderate trail riding
• Hills and inclined roads
• Longer-distance journeys
• Beach and soft-surface riding
• Mixed-surface cycling
• General outdoor transportation

Safety & Road-Use Information

Always wear an appropriate cycling helmet and inspect the brakes, tyres, wheels, battery, electrical connections, suspension, drivetrain and frame fasteners before riding.

The KETELES K800 features a 1000W motor and maximum speed of approximately 45 km/h. Public-road requirements for higher-powered electric bicycles differ by location, so the bicycle should be operated in accordance with applicable local e-bike regulations.
