Elegance, technology, and comfort
The Gazelle Grenoble C5 HMB is an electric city bike that clearly prioritizes luxury and comfort. Its design combines elegance with technical robustness, catering to cyclists who refuse to compromise in their pursuit of a superior riding experience. Advanced technical features, such as the motor and drivetrain, are closely integrated with safety and comfort.
Powerful assistance with the Bosch Performance Line
At the heart of the Grenoble C5 HMB is the Bosch Performance Line mid-drive motor. With 75 Nm of torque, this motor delivers significantly more pulling power than a standard city bike. You can feel its potential right from the first few pedal strokes. In “Turbo” mode, the bike effortlessly reaches 25 km/h, even against a strong headwind or on an incline. Thanks to the intelligent Bosch system and its advanced sensors, the electric assist remains smooth and natural. The motor responds subtly to the force applied to the pedals. You’ll also notice how quiet it is, especially in the lower assist modes.
Maintenance-free drivetrain with Gates Beltdrive and Shimano Nexus 5
A unique feature of the C5 model is the combination of a Gates belt drive and a Shimano Nexus 5 hub.
The Gates belt, which replaces a traditional chain, offers exceptional durability (up to 10,000 km). It requires no lubrication and is virtually immune to rust and dirt.
Shimano's Nexus 5 hub has been specifically designed for high-powered e-bikes. While conventional 7- or 8-speed hubs may reach their limits when faced with the high torque of a mid-drive motor, the Nexus 5 is more robust and allows for smoother shifting under load. Shifting may feel slightly stiffer than with a lightweight derailleur, but reliability and minimal maintenance more than make up for this in everyday use.
Comfort is our top priority
The Grenoble series is renowned for its comfort, and the C5 HMB takes it a step further with the addition of several suspension components. The bike is equipped with a suspension seatpost and a spring-loaded telescopic fork. These components effectively absorb shocks from cobblestones or speed bumps. The frame geometry promotes an upright and relaxed riding position. Combined with leather grips and a high-end gel saddle from Selle Royal, it ensures excellent comfort, even on rides of 50 kilometers or more. The tires also contribute to stability and shock absorption on various types of surfaces.
Security and Smart Technologies
The safety of the Grenoble C5 HMB is ensured by hydraulic disc brakes (often from Tektro or Magura), which provide excellent braking power and precise control, even in the rain.
The bike also features the Bosch smart system. With the Bosch Flow app, you can customize settings, perform remote software updates, and secure the bike against theft using a digital lock. The display is clear and easy to control from the handlebars.
Pricing strategy
The current price of a Gazelle Grenoble C5 HMB varies significantly depending on the battery capacity and year of manufacture. For a new model, the price in 2026 ranges from approximately €3,849 to €4,299. On the used market, this model is available starting at around €1,500, depending on its condition and mileage.
