Why Choose the Hidoes B9?
Dual Battery System — 48V 33.8Ah for Unmatched Range

This dual battery setup provides a pure electric range of 50–56 miles and an extraordinary pedal-assist range of up to 93 miles per charge — making the B9 one of the longest-range fat tyre electric bikes available in the UK. Both batteries are lockable with keys for security and can be removed for convenient indoor charging.
750W Motor with 65Nm Torque — 28 mph Performance
The 750W motor delivering 65Nm of torque provides strong, responsive acceleration and confident hill-climbing performance. Reach a top speed of 28 mph in pure electric mode — ideal for fast commutes, outdoor adventures, and off-road exploration — while remaining compliant with UK e-bike regulations.
Shimano 7-Speed Gears — Adapt to Any Terrain
The Shimano 7-speed gear system allows smooth, precise gear changes to suit flat roads, steep hills, and off-road conditions. The 180° pedal rotation automatically activates pedal-assist mode, making the B9 intuitive and effortless to ride for cyclists of all experience levels.
20"x4" Fat Off-Road Tyres — All-Terrain Confidence
The 20-inch by 4-inch fat off-road tyres deliver superior traction, stability, and shock absorption across all surface types — sand, gravel, mud, snow, grass, and city streets. The wide tyre profile provides a naturally stable, planted ride that inspires confidence on any terrain.
Hydraulic Disc Brakes + Electronic Brake — Safe Stopping at Any Speed
Front and rear hydraulic disc brakes combined with an electronic brake deliver smooth, progressive, and highly responsive stopping power in all weather conditions — essential for a 28 mph e-bike on varied terrain.
Front Suspension Fork — Smooth Ride on Rough Ground
The front suspension fork absorbs bumps, roots, and uneven terrain, working in combination with the fat tyres to deliver a smooth, comfortable ride on both off-road trails and city streets.
Convertible Split Seat — Passenger or Cargo
The split long seat offers flexible utility — use the full seat for a passenger or remove the rear section to reveal a built-in cargo basket for shopping, commuting, or carrying gear. Combined with the centre-mounted steel storage basket, the B9 is one of the most practical fat tyre e-bikes for everyday use.
