Hidoes B9 – Long-Range Dual Battery Electric Bike with Hydraulic Brakes

The Hidoes B9 is a versatile fat tire electric bike combining exceptional battery capacity, powerful motor performance, and practical everyday features. With two removable batteries, hydraulic disc brakes, and a comfortable extended saddle, the B9 is designed for commuting, recreational riding, and longer adventures.

The 750W rated electric motor delivers up to 65 Nm of torque, providing responsive acceleration and strong climbing performance. According to the manufacturer, the maximum unrestricted speed reaches 45 km/h in electric mode.

One of the Hidoes B9's greatest advantages is its dual-battery system. Two removable lithium batteries — 48V 18.2Ah and 48V 15.6Ah — provide a combined capacity of 33.8Ah (1622.4 Wh). The manufacturer claims a range of up to 80–90 km in pure electric mode and up to 150 km with pedal assistance. Both batteries are removable and secured with individual key locks.

Large 20 × 4.0-inch fat tires offer excellent traction and stability on asphalt, gravel, and uneven trails. A front suspension fork helps absorb bumps and vibrations, improving comfort across different riding surfaces.

Front and rear hydraulic disc brakes, combined with electronic braking, provide responsive and controlled stopping power.

The Hidoes B9 features a Shimano 7-speed transmission, allowing riders to adapt their pedaling effort to different terrain and inclines. A centrally mounted color display shows essential riding information, including speed, battery level, and riding mode.

A distinctive feature is the split extended saddle. The rear seat section can be removed and replaced with a cargo basket, adding flexibility for shopping and everyday transportation. A sturdy steel storage basket provides additional carrying capacity.

The bike also includes an LED headlight, rear light, turn signals, and reflectors for improved visibility. Its IP54 protection rating provides resistance to dust and water splashes.
