Bikepacking is attracting more and more cyclists in France. It's a way of traveling by bike where equipment is distributed in special bags attached to the frame, handlebars, and seat post. Many riders embark on self-supported routes through the forests of Fontainebleau, the Chevreuse Valley, or even set off on multi-day adventures across Europe.
Compact panniers on the frame, handlebars, and seatpost eliminate the need for a rack while maintaining good bike handling, but they also impose limitations in terms of volume. One of the key points is therefore to accurately estimate the amount of water to carry. An inaccurate estimate can quickly become a problem: too much water, and the bike becomes overloaded; not enough, and you risk running out on isolated sections, with real consequences for both comfort and safety.
To avoid having to choose between carrying more water or attaching a pannier, opt for bikes with many attachment points, such as those from the WELT brand.

Conclusion
If you're preparing for your first bikepacking trip or planning a new gravel route from Paris, the experts at Routes and Roads can help you choose the right water bottles and gear for your needs. For information on choosing bike bags, a dedicated article is available here . In this article, we explain how much water to bring, how to carry it, and which water bottles are best for bikepacking in France.
Why carefully calculate your water reserve
When cycling, water is one of the most precious resources. It allows you to sustain your effort, cook, and simply feel good, especially in hot weather. On a bike, the most reliable way to carry water remains a water bottle mounted in a bottle cage. The number and capacity of the bottles directly influence your autonomy and safety on the journey.
Staying well hydrated is vital
Bikepacking routes often follow back roads or isolated paths. Even in Europe, where infrastructure is well-developed, it's best not to rely on luck. In Paris or other large cities, it's easy to refill your water bottles, but as soon as you venture outside the city, the distances between shops can increase rapidly. On gravel routes around Fontainebleau, in the countryside or in the mountains, in the Alps as well as the Pyrenees, opportunities to resupply become increasingly scarce.
In the south of France, summer temperatures easily exceed 30°C. Add to that the steep mountain climbs, and water needs increase significantly. Before setting off, it's therefore essential to assess the distance, the climate, and the frequency of villages along the route. This allows for a more accurate estimation of the volume of water needed and efficient organization of its transport on the bicycle.
How many cans to choose
Short outings
It all depends on the duration and the desired level of autonomy. For a 2-3 hour gravel ride around Paris or the Île-de-France region, two 600-750 ml water bottles are generally sufficient. This covers essential needs without adding weight to the bike. They can be mounted in the bottle cages on the downtube and seat tube.
Everide CLUXX bottle cages
For example, CLUXX Everide bottle cages hold bottles securely, even on rough terrain, and their design is compatible with most models.
Day trips
For a full day's ride, it's best to bring three water bottles, or two bottles supplemented by a hydration system. This type of flexible reservoir, placed in a backpack or frame bag, allows you to drink through a tube without taking your hands off the handlebars—a real advantage on technical sections.
A hydration system is an excellent solution for easy drinking while riding. Placed in a backpack with the hose accessible over the shoulder, it allows for unrestricted hydration. This is a particularly popular option for those aiming for performance over long distances.
Multi-day bikepacking trip in France
For self-supported trips, a water volume of 3 to 5 liters is recommended. In hot regions or on isolated sections, it's best to aim for the higher end of this range. This volume can be divided between several containers and additional reservoirs, such as soft flasks or collapsible water bottles. It's important to plan for water not only for drinking, but also for cooking, washing dishes, and maintaining basic hygiene. Keep in mind that for technical uses, clean water is sufficient, but for drinking, it's essential to boil it at least once or, better yet, use a portable water filter.
How to distribute the containers
The idea is to distribute the water bottles without compromising the bike's handling or balance. Generally, one or two bottles are placed in the frame's bottle cages. The third can be mounted under the downtube if the bike allows it.
Most often, water bottles are placed inside the frame, but they can also be attached under the downtube or slipped into a handlebar bag.
Additional supplies – such as soft flasks or collapsible reservoirs – can be easily stored in a handlebar bag or frame bag. This solution is particularly useful on long sections without access to water.
For added convenience, several types of containers can be combined:
-
Water bottles - sturdy, easy to use and clean. The Cluxx Ergo models in 550 and 750 ml can be easily handled with one hand while riding.
-
The hydration system allows you to drink continuously and carry more water. Ideal for backpacks.
-
The collapsible tank serves as a reserve and takes up very little space when empty.
Resistant and durable, CLUXX water bottles and bottle cages are your reliable partners.
How to choose your water bottles
A good water bottle should be leak-proof, comfortable to hold, and resistant to temperature variations. For bikepacking, choose food-grade plastic models with a flexible body: they don't vibrate and fit easily into bottle cages. It's also best to opt for a bottle with a cap that protects the valve from dust and mud.
Flexible tanks must be made of a robust material, with a reliable valve. Their volume generally varies between 1.5 and 3 liters, and they fold easily after use.
Beyond hydration, water remains essential for all uses while traveling.
When to reduce your water supply
It's possible to reduce the amount of water you carry if your route passes through populated areas with regular water points—shops, cafes, fountains, or wells. That said, even then, carrying at least an extra liter is a wise precaution. Weather conditions, a headwind, or unforeseen technical problems can lengthen your journey.
Conversely, in mountainous or isolated areas, it is recommended to increase the reserve to 1.5 or even 2 times the initial estimate. Carrying a little extra water is always less risky than running out.
For a typical bikepacking trip of 100 to 150 km with an overnight stay, you can plan for:
-
2 x 0.75L CLUXX bottles on the frame:
-
1 flexible 1.5 L reservoir in a bag or backpack;
-
1 collapsible 1L water bottle as a spare.
That's about 4 liters of water, enough for an active day and preparing dinner.
Conclusion
The number of water bottles and reservoirs you need for bikepacking depends on the route, the climate, and your personal habits. But the principle remains the same: transport and conserve water efficiently. A good supply ensures autonomy, while properly distributing the bottles helps maintain the bike's balance and handling.
