Gazelle: A Royal Legacy
To understand the Ultimate C5, you first need to learn about its manufacturer. Koninklijke Gazelle is a legend in the cycling world. Founded in 1892 in Dieren, the Netherlands, the brand has grown from a small local blacksmith shop into a global market leader. Since 1992, it has held the title “Royal” in recognition of its contribution to Dutch cycling culture.
Gazelle is known for its quintessentially Dutch sturdiness combined with a keen sense of modern design. The brand pioneered the e-bike revolution (its first model dates back to 2005), and this early lead is reflected today in its exceptionally high-quality craftsmanship.
The sporty luxury of the Ultimate series
Within the extensive Gazelle lineup—which ranges from the practical Orange city bikes to the exceptionally comfortable Avignon models—the Ultimate series holds a special place. Its name says it all: it is the brand’s flagship model.
The Ultimate is positioned as an active bike for tourism and commuting. While the Grenoble line is aimed at the typical urban cyclist, the Ultimate is designed for those seeking extra stiffness, handling, and technical performance. The frame has a sleeker design, the components are higher-end, and the riding experience is noticeably sportier without sacrificing comfort.
3 versions
The 2026 lineup of the Ultimate series includes three main models: the Ultimate C380, the Ultimate T11, and the Ultimate C5 HMB.
- The Ultimate C380 features an Enviolo continuously variable hub for maximum comfort.
- The Ultimate T11 is the sporty version with a derailleur, designed for hilly terrain.
- The Ultimate C5 HMB (also known as the C5+) offers the perfect balance, featuring a sturdy 5-speed hub and a belt drive.
Technical specifications
The Gazelle Ultimate C5 HMB features an oversized, sturdy aluminum frame with a seamlessly integrated battery and motor. This not only creates a sleek design but also lowers the center of gravity, improving stability.
| Component | Specification |
|---|---|
| Engine | Bosch Performance Line (75 Nm torque) |
| Transmission | Gates Carbon Drive CDX Belt |
| Speeds | Shimano Nexus 5-speed hub |
| Battery | Choose from: 540 Wh, 600 Wh, or 800 Wh (integrated into the frame) |
| Screen | Bosch Kiox 300 Smart System |
| Brakes | Shimano MT200 Hydraulic Disc Brakes |
| Fork | Suntour air-sprung telescopic fork (80 mm) |
At the heart of this bike is the combination of the Bosch Performance Line motor and the Gates belt. The motor delivers 75 Nm of torque, more than enough to ride into the wind or tackle a steep hill with ease. The Shimano Nexus 5 hub is specially designed for powerful mid-drive motors. Where a standard 7- or 8-speed hub might reach its limits, the Nexus 5 is more robust and allows for smooth shifting even under light load.
The belt replaces the traditional chain: no oil stains, minimal maintenance, and virtually silent operation. Plus, a belt lasts up to three times longer than a conventional chain.
Behavior on the road
Position & Comfort
As soon as you hop on the Ultimate C5, you’ll notice an active yet comfortable riding position. Less upright than a typical city bike, but less reclined than a MTB. The adjustable stem allows you to fine-tune your position perfectly. The ergonomic grips and high-quality saddle ensure lasting comfort, even after 50 kilometers.
Handling & Maneuverability
The Ultimate’s frame is exceptionally stiff. This provides excellent control in corners: the bike remains stable and responds instantly to handlebar movements. The tires Schwalbe Marathon tires and suspension fork effectively absorb road bumps. The stability inspires confidence, even at high speeds on descents.
The Bosch Smart System Experience
With the Bosch Kiox 300 display, you get a true cockpit experience. The color display remains easy to read even in direct sunlight and offers navigation via the eBike Flow app. You can also customize the assistance modes, switching from "Turbo" to "Eco" mode with just a few clicks.
Practical use
Integrating the battery into the frame is both stylish and practical. It can be charged directly on the bike or easily removed for charging indoors.
Range depends heavily on the battery choice and riding style. With the standard 540 Wh battery, you can generally expect a range of between 50 and 110 km. With the 800 Wh version, rides of up to 150 km are entirely possible.
Conclusion
The Gazelle Ultimate C5 HMB is a perfect example of what a modern e-bike should be. It combines Gazelle’s legendary reliability with advanced technologies from Bosch and Shimano. It strikes an excellent balance between sportiness and comfort.
The belt drive and Nexus 5 hub require very little maintenance, and the Bosch Smart system receives regular updates via the app. What’s more, this bike features one of the most attractive frames in its premium category.
Of course, this quality comes at a price. But if you’re looking for a reliable bike for your daily commute that’s also enjoyable for weekend rides, the Ultimate C5 HMB is a well-worth investment.
