❓ Frequently Asked Questions (FAQs)
Q: What range can I expect from the 33.8Ah dual battery?
A: The 33.8Ah dual battery system is one of the largest on any UK e-bike, offering an estimated range of 80–120+ km on electric assist depending on terrain, rider weight, and assist level. This makes the B9 ideal for long-distance commuting and touring.
Q: Can I use just one battery at a time?
A: Yes. Each battery is independent with its own key lock, so you can use one or both depending on your range needs. This also allows you to charge one battery while using the other.
Q: How long does it take to charge both batteries?
A: Each battery typically takes 4–6 hours to charge with the included charger. Both batteries are removable for convenient indoor charging.
Q: Why are hydraulic disc brakes better for a heavy e-bike like the B9?
A: Hydraulic disc brakes provide significantly more stopping power with less hand effort compared to mechanical brakes — essential for a heavier dual-battery e-bike, especially when carrying cargo or a passenger. They also self-adjust over time for consistent performance.
Q: Can the B9 carry a passenger?
A: The B9 features a split-design extended seat with a removable rear section, making it suitable for carrying a passenger. Please refer to the user manual for the official maximum load capacity.
Q: Is the B9 suitable for off-road riding?
A: Yes. The fat tyres, suspension fork, and powerful motor make the B9 capable on gravel, sand, mud, and uneven surfaces, in addition to urban roads.
Q: How does the 7-speed transmission work with the electric motor?
A: The Shimano 7-speed gearing works alongside the motor to give you precise control over your riding effort. Use lower gears for climbing hills and higher gears for flat, fast riding — in any of the three riding modes.
Q: How difficult is assembly?
A: The B9 arrives partially assembled. Most riders complete setup in 30–45 minutes using the included tool kit and user manual. No specialist tools are required.
Q: What makes the Hidoes B9 stand out from other electric bikes in the UK?
A: The B9’s 33.8Ah dual battery system is its defining feature — offering nearly double the range of standard e-bikes. Combined with hydraulic disc brakes, 7-speed gearing, a passenger seat, and a storage basket, it’s the most feature-complete, long-range fat tyre e-bike available in the UK at this price point.
