250W Geared Hub Motor for Smooth Everyday Support
The BK7S is powered by a 250W brushless geared hub motor that delivers smooth, responsive and practical pedal assistance for daily riding. Working together with 3 PAS levels and a Shimano 7-speed gear system, it helps riders start more easily, maintain steady speed and handle moderate inclines with less effort. The motor is designed to provide reliable support exactly when you need it, making commuting, city rides, school trips and relaxed weekend routes feel easier and more enjoyable.
Aluminium Alloy Frame for a Balanced Daily Ride
The BK7S uses an aluminium alloy frame designed to keep the bike practical, stable and easy to handle in everyday conditions. Compared with many bulky entry-level e-bikes, the frame helps the BK7S feel more balanced on mixed urban routes, from city streets and cycle paths to park roads and light gravel sections. With a 23.3 kg net weight and 120 kg maximum load, it offers a solid balance of durability, usability and day-to-day riding confidence for commuters and casual riders alike.
Removable Integrated Battery for Easier Daily Use
The BK7S is equipped with a 36V 12Ah (432Wh) removable lithium-ion battery that is neatly integrated into the frame for a cleaner overall look. It supports both on-bike and off-bike charging, which makes everyday use much more flexible for riders who live in flats, store the bike downstairs or prefer to charge at work. With a claimed range of 35–90 km, it is built to cover commuting, daily errands and relaxed weekend rides with less charging hassle. The battery lock also adds extra day-to-day reassurance when the bike is parked.
Suspension Fork That Takes the Edge Off Rough Roads
The BK7S features a front suspension fork designed to improve comfort on uneven city roads and lighter off-road routes. It helps absorb repeated shocks from broken tarmac, paving joints, kerb transitions and rough cycle paths, so the ride feels less harsh on your hands and upper body. For riders who use their e-bike for commuting as well as casual leisure riding, this setup makes the bike feel more forgiving and easier to control when the road surface is not ideal.
