Long-range dual-battery fat-tyre electric bike
The Hidoes B9 combines a 750W rear-hub motor with two removable 48V batteries, providing a combined capacity of 33.8Ah. It can reach up to 28 mph (45 km/h) and is intended for experienced adult riders using suitable private land.
Wide 20 × 4-inch pneumatic tyres, a front suspension fork and hydraulic disc brakes help provide stability and control over varied surfaces. Shimano 7-speed gearing, an HD colour display, integrated lighting and a front basket make the B9 practical for longer leisure and utility rides.
Electric Scooters London provides product guidance and UK-based after-sales support through our London workshop.
Dual removable batteries for longer journeys
The 48V battery system combines one 18.2Ah pack with one 15.6Ah pack, for a total of 33.8Ah. Both batteries can be removed and locked, making indoor charging and secure storage more convenient.
Two chargers are included. Charging takes approximately 6–9 hours, depending on the remaining charge, battery temperature and charging conditions.
Fat tyres, front suspension and hydraulic brakes
The 20 × 4-inch pneumatic tyres provide a broad contact patch, while the front suspension fork helps absorb vibration and impacts from uneven ground. Front and rear hydraulic disc brakes provide progressive, controlled braking.
Clear controls with practical carrying capacity
The HD colour digital display shows essential riding information, and Shimano 7-speed gearing lets the rider adjust cadence for gradients and changing terrain. The lighting system includes a headlight and a rear light with brake-light and turn-indicator functions.
A front basket is included for light cargo. Keep every load secure and within the bike’s total 150 kg load limit. Do not treat the rear pad as a passenger seat unless the supplied instructions expressly confirm that use.

Frequently asked questions
Is the Hidoes B9 road legal in the UK?
No. This 750W B9 can reach up to 28 mph (45 km/h), so it does not meet UK EAPC requirements and is not supplied as a road-legal vehicle. It is intended for use on suitable private land with the landowner’s permission.
How does the dual-battery system work?
The B9 has two removable 48V batteries: one 18.2Ah pack and one 15.6Ah pack. Together they provide 33.8Ah of capacity. Switch the bike off before removing or refitting either battery, and confirm that both packs are locked securely before riding.
What riding range can I expect?
A full charge can provide approximately 40–56 miles (64–90 km) in favourable conditions. Higher assistance levels, heavier loads, hills, low temperatures, headwinds, frequent stops and under-inflated tyres will reduce the achievable distance.
How long do the batteries take to charge?
Charging takes approximately 6–9 hours. Two 54.6V 2A chargers are included, allowing each removable battery to use its own charger. Follow the battery-safety instructions and never leave charging batteries unattended.
What rider size and load can the B9 accommodate?
The recommended rider height is approximately 170–210 cm. The 150 kg maximum load includes the rider, cargo and fitted accessories. Do not assume the rear pad is approved for a passenger unless the supplied instructions expressly confirm it.
Does the bike require assembly?
Yes. The B9 arrives partially assembled and requires final assembly and safety checks before use. Follow the supplied instructions, then check the handlebars, wheels, pedals, fasteners, brakes and tyre pressures before the first ride.
