Hidoes® B9 Dual Battery Electric Bike – 48V 33.8Ah Fat Tyre

Hidoes B9 Dual Battery Electric Bike – 48V 33.8Ah Fat Tyre Power

The Hidoes B9 Dual Battery Electric Bike is a high-capacity fat tyre electric bike built around a dual removable battery system. Its total battery capacity is 48V 33.8Ah, made up of one 48V 18.2Ah battery and one 48V 15.6Ah battery

With a 750W peak motor, a restricted 25 km/h assist setting, 20 x 4.0-inch fat tyres, a front suspension fork, hydraulic disc brakes, Shimano 7-speed gearing, a colour display, lighting with indicators, and a practical front storage basket, the Hidoes B9 is designed for strong utility-style performance on suitable private land.

⚡ Power & Performance

The Hidoes B9 uses a 750W peak motor with a restricted-assist setting for 25 km/h / 15.5 mph operation, where required. It also supports an unlocked higher-speed mode for off-road/private-land use only. Shimano 7-speed gearing gives the rider more control over cadence, climbing effort and mixed-surface riding.

🔋 Battery & Range

The Hidoes B9 is fitted with a 48V 33.8Ah dual removable lithium battery system. This is made up of a 48V 18.2Ah battery and a 48V 15.6Ah battery, giving a total capacity of 33.8Ah. Both batteries are removable, lockable and designed for convenient charging.

The rated maximum range is up to 90 km (6 miles) under ideal riding conditions. The dual battery setup is the key upgrade on the B9, giving riders more usable battery capacity than a smaller single-battery electric bike.

Range Notice:
The 90 km / 56 mile range is based on ideal riding conditions. Actual range varies depending on rider weight, load, assist level, Terrain, wind conditions, temperature, tyre pressure, battery condition and riding style.

🛞 Tyres, Suspension & Ride Comfort

The 20 x 4.0-inch fat tyres provide a wide contact patch for stability, cushioning and grip across mixed surfaces. The front suspension fork helps reduce vibration from uneven ground, while the long saddle layout and upright position support a comfortable riding setup.

💡 Controls, Display & Lighting

The colour LCD clearly shows key ride information. The lighting system includes a front LED headlight, rear tail light, brake light and turn indicators for improved visibility and rider signalling.

🛡️ Braking, Safety & Build Quality

The Hidoes B9 uses front and rear hydraulic disc brakes with electronic brake support for strong, controlled stopping performance. The iron and aluminium alloy frame supports a maximum load of 150 kg, while the IP54 rating helps protect against light splashes.

🔐 Security & Smart Features

The two removable batteries are secured with key locks for added convenience and battery security. The B9 also includes a front storage basket and cargo-ready rear structure for practical carrying capacity on suitable private land.

🔌 Charger & Power Specification

The Hidoes B9 includes dual chargers for its dual-battery system. Charging time is approximately 6–9 hours, depending on battery level, charging conditions and battery condition.
