Product Description
Lightweight City Electric Bike for Everyday Commuting
The BK18PRO is a lightweight step-through city electric bike designed for commuting, shopping, work journeys and regular urban travel.
With a net weight of approximately 20.5 kg, its aluminium alloy frame is easier to manoeuvre through city traffic and handle during everyday use, while supporting a maximum load of 120 kg.
Step-Through Frame for Easier Access
The low-step frame makes getting on and off easier than with a conventional high crossbar design. It is particularly practical for stop-start city riding, shopping trips and riders carrying everyday bags.
Low-Maintenance Belt Drive
The BK18PRO uses a belt drive with a single-speed transmission instead of a conventional chain.
The belt runs quietly, stays cleaner during everyday use and requires less routine maintenance. Regular chain lubrication is not required, helping reduce grease and dirt during commuting.
Torque Sensor for Responsive Assistance
The integrated torque sensor detects the force applied to the pedals and adjusts electric assistance accordingly.
This provides smooth, progressive and responsive support when starting from traffic lights, accelerating through city traffic or riding on moderate inclines.
250W Motor with Two Riding Modes
The 250W motor provides pedal assistance up to 25 km/h.
The BK18PRO offers two riding modes:
Pedal Assistance Mode: Electric assistance supports the rider while pedalling.
Bicycle Mode: The bike can be ridden using pedal power without electric assistance.
This simple setup is well suited to everyday commuting and regular city riding.
Hydraulic Disc Brakes
Front and rear hydraulic disc brakes provide responsive and controlled braking during everyday urban riding, including descents, wet roads and busy traffic.
Removable 36V 10.4Ah Battery – Up to 80 km Range
The removable 36V 10.4Ah lithium-ion battery (374.4Wh) provides a reference range of approximately 40–80 km, depending on riding conditions.
The battery can be removed for convenient indoor charging. Typical charging time is approximately 6–7 hours.
700C × 42C Puncture-Resistant Tyres
The BK18PRO is equipped with 700C × 42C puncture-resistant pneumatic tyres for city roads, cycle paths and everyday paved surfaces.
Reflective elements on the tyres help improve side visibility during lower-light conditions.
Lighting, Mudguards and App Connectivity
The bike features an LED front light, rear light and extended mudguards for practical everyday commuting.
The multifunction LCD display shows key riding information such as speed, distance, assistance level and battery status.
Mobile App connectivity allows compatible bicycle and riding information to be accessed through a smartphone.
IP54 Protection and Easy Assembly
The BK18PRO has an IP54 protection rating, providing protection against limited dust ingress and water splashes during normal everyday use.
The bike is delivered approximately 85% pre-assembled, with tools and instructions included for final assembly.
