Nous devons dans les jours qui suivent transporter une quantité d"essence supplémentaire pour une dizaine de jours (environ 1 litre).
Quel est le contenant le plus approprié en sachant qu'ici je ne dispose pas de magasin de materiel de camping ?
J"avais pensé à une simple bouteille de Coca mais je ne sais pas si avec les vibrations dues aux mauvaises pistes celle-ci ne risque pas de s'ouvrir avec la pression due aux gaz émis ?
bonjour à vous et joyeux noel
pour transporter un complément d'essence, j'avais une gourde décatlon qui a fuit magnifiquement dans la sacoche de ma femme.
j'avais peut etre sous estimé les variations de pression que l'on peut avoir en montant sur l'altiplano.
j'avais fait le plein à nazca (environ 600 m) et nous sommes montés à 4000 m.
le pb se pose aussi avec les pneumatiques de vélo.
de toutes façons, mon réchaud est tombé en panne et nous avons fini par manger froid.
bon courage et pas trop d'excès alimentaires sur la route.
je n'ai pas testé, mais une bouteille de Coca supporte au moins la pression des gaz du Coca. En entrouvrant de temps en temps la bouteille (quand l' altitude ou la température s'élève), la montée en pression devrait rester assez limitée, surtout si la bouteille n'est remplie qu'aux deux tiers. Donc ça devrait tenir, si le bouchon ne suinte pas. Mais dans le doute, j'éviterais quand même de loger cette bouteille dans une sacoche...
Concernant la pression, la tenue des bouteilles de coca est remarquable: lors de mes études, on utilisait une telle bouteille pour pressuriser un circuit pneumatique, et on a testé la résistance: à 10 bars, la bouteille émet un bruit de cristal, mais résiste tout de même à la chute d'un marteau lancé de plusieurs mètres.
Le risque est plutôt la tenue à l'agression chimique, mais le PET, le plastique qui compose ces bouteilles est visiblement assez résistant:
http://solutions-in-plastics.info/fr/plastics/datasheets/pet/ERIKS%20-%20PET%20fiche%20technique.pdf
(dernière page)
Donc, à mon avis, c'est faisable, mais stocke la tout de même bouchon en haut, et à l'extérieur des bagages.
Les bouteilles de Fanta 1l sont pas mal car le plastique y est plus costaud que dans les autres bouteilles...encore faut il pouvoir en trouver ce qui n est pas le cas partout.
Pour la pression générée par la montée en altitude ou par le mouvement, il suffit de comprimer un peu le haut de la bouteille avant remplissage du carburant. Si le volume doit augmenter dans la bouteille, celle-ci retrouvera sa forme initiale avant que le bouchon ne soit expédié sur orbite....ca laisse de la marge!
Et puis bien penser à ouvrir tous les jours pour laisser echapper la surpression.
"Allons-y, puisque le jour se leve encore...!"

Une bouteille de soda, type coca, pleine d'eau, supporte sans problème que cette eau se congèle: le volume du contenu de la bouteille augmente alors de 9%, ce qui est compensé par l’élasticité du plastique.
Par ailleurs, l'essence se dilate de 15% pour une augmentation de température de 100°C.
Donc, en gros, si tu mets de l'essence à 0°C dans ta bouteille, que tu la remplis complètement, et qu'elle monte à 60°C, ce ne sera pas plus sollicitant pour la bouteille que y faire geler de l'eau.
D'après quelques sites internet, une bouteille de coca résiste à 15 bars, alors que la pression d'une bouteille avec du coca dedans, jamais ouverte, à 34°C est de 3.8bars.
Donc il y a de la marge...
Donc y a de la marge...on est bien d accord, à ceci pres que...

oui peut etre, mais a pression constante, ce qui n est pas tjs le cas a velo notamment lorsqu on monte et descend en altitude.

sans partir dans la thermodynamique, le Volume est autant fonction de la Pression que de la Temperature: V=nRT/P
Pour terminer... ne pas confondre volume de dilatation d un liquide et son volume de vaporisation.
Derniere chose pratique concernant les bouteilles plastiques: sachant que la pression atm (ext ) chute quand l altitude augmente, la contrainte exterieur sera moins forte sur la bouteille plus on montera, donc la deformation int n en sera que plus aisée.
Dans l autre sens la pression ext augmentant avec la descente en altitude, le fait de remplir une bouteille en altitude risque de la faire debordée en redescendant....
l interet des gourdes en dur est d etre resistant a la Pression ext et donc ne pas subir de deformation mais resistant a une montee de la pression interne moyenne.
L interet des bouteilles pour carburants est d etre resistant a une montee de la Pression interne...c est tout leur interet.

je suis resté à PV=P'V' à température constante et au niveau de la mer (Mariotte, il a jamais été sur l'Altiplano où en plus, on se les pèle)
grâce à VF, mon niveau (intellectuel?) augmente.
bonne année à tous et que cela pète pas trop.
Merci à tous pour toutes vos réponses mais... à l'heure où je vous écris mon MSR vient de rendre l'âme. Nous allons donc effectuer la traversée du sud Lipez sans réchaud.
Je prend bonne note de toute vos remarques et vous souhaite de passer une joyeuse année 2011.
Finalement vous avez de la chance, car après la multitude de réponses, le nombre d'étude de qualité que vous auriez eu à faire vous auraient un peu gaché votre plaisir.😉
Davance desole pour les accents et cie, je suis sur un clavier anglais. Je prepare un voyage en norgeve a velo, avec budget moyen voire petit. Et qui dit…
Attention Air France a encore modifié sa réglementation en ce qui concerne les vélos. Le forfait vélo a disparu. Le vélo est considéré comme un bagage. Chaque…
Je souhaite faire Morlaix Brest ( via Roscoff et la littoral V45) nous commencerons à rouler le 16 aout pour 13 jours (avec des pauses visites iles , surf etc..) Est ce qu'il y a beaucoup de circulation à cette époque de l'année car j'ai 2 enfants de11 et 13 ans et on n'aime pas rouler au milieu des voitures (on a déjà fait velomaritime ; Caen - Cherbourg, loire : Orléans- Saumur, Velodyssée : Nantes - Royans, les canaux : nivernais , bourgogne etc ... et il y avait beaucoup de voies réservées aux vélos ce qui n'est pas le cas sur cet itinéraire).
Merci de votre aide si vous avez déjà parcourue cet itinéraire fin aout.

Ca y est j'ai mon billet d'avion, départ mi novembre, retour mi-mars.
arrivée santiago et je repars depuis Buenos Aires.
J'ai deja été dans le sud de l'argentine, notamment le parc torres del Paine, et j'ai très envie d'y retourner pour faire le grand W, j'avais fait le petit.
Je souhaite aussi randonner qq foois et pourquoi pas faire un sommet. Je grimpe et je fais occasionnellement de l'alpinisme, donc ce sera avec un guide de toute façon.
Je compte démarrer vers temuco au chili, j'ai dans l'idée d'aller vers les lac, puis prendre la careterra austral.
Je sais pas si je vais aller jusqu'à Ushuaia, parait que cela vaut pas tant que cela la peine, à part pour dire qu'on a été au bout de la terre.
j'ai vu vite fait qu'il y'avait des lac en Argentine.
Je n'ai pas d'itinéraire précis. Mais ce que je souhiaterai, c'est qu'une fois arriver le plus au sud de mon vooayage, faire une mini croisière pour voir des annimaux.
Des conseils pour cela?
qu'avez vous pris comme sac de couchage? un 0 degré suffit?
et ultime question, réchaud à essence ou est-ce que je peux m'en sortir avec mon réchaud gaz?
Cet été nous prévoyons de pédaler sur l'EV 19 qui longe la Meuse de Langres jusqu'à Rotterdam.
Mon questionnement concerne le retour jusqu'à Nantes.
Savez vous quel est le meilleur retour possible? J'en appelle à vos expériences.
Je voyais que Flixbus ne prenait pas les vélos.
En train, je pense que c'est possible avec de multiples petits trains.
On se questionnait aussi sur l'existence d'un bateau qui irait de Rotterdam jusqu'à St Nazaire et qui pourrait charger des passagers avec vélos.
Toutes vos expériences partagées nous seront bien utiles et nous vous en remercions.
Bonne soirée
Hi there,
I’ve been road cycling for several years, and I’m about to switch to gravel in the next few days—I’m waiting for my bike, which should arrive this week.
I’m planning a bikepacking trip in a few weeks along the Véloroute V81, also known as the Vélosud, from Biarritz to Le Barcarès.
Has anyone here already done this route? Any info is welcome, whether it’s about the route itself, gear, or accommodation. I’ll prioritize staying with locals as much as possible. On that note, I just signed up for the brand-new site *Guidon et Couette* ((www.guidon-et-couette.fr)), which offers free accommodation between cyclists across the country, but there’s almost no one listed along my route!
Thanks in advance.
Laurent.
I’m planning to build a new touring bike.
I want to prioritize lightness.
That said, I’m tempted by a suspension fork that could offer some comfort on rougher roads.
The recent appearance of gravel suspension forks on the market might meet my needs—at least on paper.
I’m particularly considering the RockShox Rudy Ultimate XPLR fork.
Unlike MTB forks, its travel is short: either 30 mm or 40 mm.
It weighs 1400 g, which is 400/500 g more than a steel fork.
Any thoughts or real-world feedback on this?
I’m also wondering about the durability of magnesium (lower leg) for long-distance bike touring.
And what’s the impact of skipping the manufacturer-recommended maintenance every 50 and 200 hours? That’s bound to happen on a long trip unless you carry extra gear.
More generally, how reliable are these kinds of forks?
Hi everyone,
I wanted to share with you the incredible feat my friend José, who’s 72 years old, is currently undertaking. He left Auterive near Toulouse on Monday, May 18, 2026, on his non-electric bike, heading for the North Cape in Norway!
You can follow his route on the link below—he’s currently in Sweden:

I’m making an exception and creating a separate post this time, since it’s all about France. In May, we spent a week in Provence, specifically in the Luberon, exploring the cycling routes *Autour du Luberon à Vélo*, the *Véloroute du Calavon* (part of EuroVelo 8), and the shorter *Les Ocres à Vélo* route. Together, they gave us an amazing journey through rolling hills, vineyards, lavender fields still green in spring, and some of the most stunning landscapes in southern France.
It was, of course, the perched villages that impressed us the most. We visited Gordes, Roussillon, Bonnieux, Lacoste, Lourmarin, Ménerbes, Oppède-le-Vieux, Cucuron, and Lauris. Many of them are among the most beautiful villages in Provence, and it’s hard not to agree with that reputation.
One interesting point is the route of EuroVelo 8 in this part of the region. The official path mainly follows the old railway line of the *Véloroute du Calavon*, which is very comfortable and safe. But in our opinion, cyclists traveling EuroVelo 8 around the Mediterranean would discover even more treasures if the route passed through villages like Bonnieux, Lacoste, or Oppède-le-Vieux.
We were also pleasantly surprised by how safe cycling felt. Most of the route takes small local roads, but traffic is light, drivers are respectful, and road design really takes cyclists into account. It’s one of those places where you can ride peacefully even without separated bike lanes.

Hi there, we’re planning a Munich to Venice bike trip at the end of June 2026. Getting back from Venice to Toulouse by train with 4 bikes isn’t straightforward. What return options have others who’ve done this trip chosen? Any tips or great deals would be much appreciated. Thanks a bunch! !
Hi everyone,
Happy owner of a Pegasus Estremo bike with a Rohloff hub, which is giving me trouble with the SF11-NCX-FT-E-LITE 700C TS 300/0 fork (serial number TD01329060). It’s starting to show its age, and I’d like to repair it to extend the life of my beloved bike.
The suspension is gone, and there’s an oil leak from the seals.
Does anyone know how to repair it? Where can I find parts that are about fifteen years old? Or where to find an identical replacement fork? Just to clarify, the Magura HS11 brakes are mounted using Firm Tech, meaning they’re on pivots behind the fork, facing the frame.
Hi, I'd like to know if anyone has done this route recently or has reliable info.
Does the track exist, and most importantly, is there sand (for biking)?
Any info is welcome.
Cheers,

Hi there,
New to bike touring,
I’d love to start with a section of the Via Rhona to explore and share (route to be decided).
Looking forward to exchanging tips!
I’m landing in Madagascar with a buddy before the end of April 2026. We’re planning to bike around for about twenty days or so. We don’t have a specific goal other than exploring the country and meeting the locals.
Ideally, we’d prefer a loop route starting from Antananarivo with a good chunk of it along the coast. On the bike side, we’re used to riding 6 to 8 hours a day, depending on the needs, encounters, and mood 😉 Any feedback or tips from trips around this length?
A big thank you to Lazarou for all the info you share in this forum!
I'm passionate about Morocco, which I cycled through back in 2009.
Last year, my wife and I explored the High Atlas by tandem. Completely smitten, we're heading back in April (Anti Atlas) and May (High and Middle Atlas), still on our tandem.
Do you have any info on the track between Amezri and Ali Ait Nito? Are the river crossings in the Tessaout still there? It's not easy to navigate with a loaded tandem... especially if the river level is high due to this year's heavy snowmelt!
Thanks in advance for any tips you might have, and best wishes for health in this new year!

Tout d'abord... bonne année ! De belles routes à vous en 2017 !
Je voyage depuis quelques années avec un VTT de très bonne qualité mais équipé de freins à disques hydrauliques. Je vis (pédale) avec l'inquiétude d'avoir une panne (fuite, bulle d'air, chaleur qui fait que le liquide...). Mon vélociste me dit qu'il est impossible de les changer pour des V brakes.
Qu'en pensez-vous ? Est-ce que je prends un gros risque à continuer (seule) avec ces freins ? D'avance je vous remercie pour vos bonnes idées.
First post here to share a quick recap of our west-to-east bike trip along Algeria’s coast in January 2025.
It was just the two of us—my partner and I—with French passports and not a word of Arabic. No friends or welcoming hosts in the country.
Under those conditions, we’d strongly advise against going.
Our original plan was to follow the coast from Algiers to Tunis. We ended up cycling from Algiers to Béjaia, then took the train from Béjaia to Annaba (with a stop in Constantine), and finally biked to the border.
We were tailed by police the whole way—whether on our bikes, on the train, or even on foot while exploring towns. On top of that, we couldn’t wild camp and were limited to the few state-approved hotels that accept foreigners. Under those circumstances, connecting with locals was especially tough.
With such an omnipresent and intrusive police presence, we’d definitely recommend against this destination for bike touring. A really sad situation that completely cuts you off from the local population...
We’d been warned, we went to check it out, and we weren’t disappointed!
Hi there,
I’m planning the route to cycle from Lille to Nordkapp with my partner.
Duration: 3 months, from May 1st to July 31st, 2026.
In the attached details below, I need to add some "non-riding" days (rest days, basically).
So I’m looking to "shorten" the trip by taking ferries or trains for some stretches. Which areas could I skip?
Thanks in advance for your great tips.
Have a good evening.

Just a few words about the loop I did by bike in Yunnan.
Entry and exit
I entered China through the Sino-Vietnamese border crossing at Lào Cai / Hekou under the 30-day visa exemption currently available to French nationals and others.
The process was simple and quick. A Chinese police officer even helped me complete my electronic pre-registration at a computer kiosk. I wasn’t aware this formality was required—it’s similar to Thailand’s TM6.
No issues with the bike.
I left the country via the Sino-Laotian border crossing at Mohan / Boten.
The atmosphere was a bit chaotic there, but again, no problems with the bike.
The timing
I visited Yunnan in February 2026.
Weather-wise, at higher altitudes (between 1,500 and 2,000 meters), it was around ten degrees at night and in the mornings, and around twenty degrees at the hottest part of the day.
I had two days of rain, so I took the bus to keep moving. Otherwise, clear blue skies.
Culturally, Chinese New Year fell on February 17th (and the 15 days following), right in the middle of my trip. Because of this, my take on the traffic might be off.
Accommodation and food
I always found a hotel to stay in for prices ranging from 8 to 15 €. Except in Kunming (the capital), where many hotels were fully booked (Chinese New Year). I ended up at a 100 € hotel with great value for money.
A bowl of noodles costs about 1.5 € on average.
Onboard electronics
Since my smartphone doesn’t support eSIMs, I subscribed to a China plan with my carrier. Otherwise, for much cheaper, Alipay offers eSIMs for foreigners that allow access to services usually blocked for Chinese users (WhatsApp, Facebook, etc.).
An internet connection is essential for paying with Alipay or WeChat, as this payment method is widespread.
I only managed to use Alipay.
Either way, always carry cash because sometimes there’s no signal, or the merchant only accepts WeChat.
Also, it’s best to bring a power adapter when you arrive rather than struggling to find one.
Traffic and roads
The Chinese aren’t reckless drivers. They follow traffic rules and watch out for cyclists. This is slightly less true in Xishuangbanna (the region bordering Myanmar and Laos).
In urban areas, there are almost always wide bike lanes, separated from other roads, where bikes, electric mini-scooters, and scooters share the space pretty harmoniously.
The roads are in great condition, and traffic is generally manageable—even light—except for one stretch (Eshan -> Yangwu).
Most traffic is absorbed by expressways, China’s equivalent of highways: toll roads that are off-limits to slow vehicles.
You’re never far from these expressways; sometimes you even ride alongside them, which can be noisy at times.
The climbs are usually reasonable, around 5% to 6%. From what I remember, the steepest section was between Menglun and Mengla, with gradients of 8% to 10%, sometimes more.
Riding at these altitudes—though modest—took a bit of getting used to.
The route
I didn’t plan anything in advance. My only goal was to reach Kunming. I don’t know why, but just hearing the name of that city, like Yunnan, always felt dreamy to me.
Hi! I’m planning to visit the Stockholm Archipelago by bike in early April.
Do you know if the boats will be running between the different islands at that time of year? For those who’ve already been, all your tips and recommendations are welcome—accommodation, etc. Also, do you know where I can rent a bike in Stockholm? Thanks so much in advance for your help!
Hello there, pedal-powered Young Boys!
Claudio (still from Faverges)
dreaming about a cycling getaway in Italy from Faverges (train all the way to Turin)
from Turin down to Venice along the Po River and back via the Padana (Alta Italia da attraversare – Northern Italy to cross)
The tricky part is getting from Chioggia to Venice.
I read it’s possible by hopping on a boat from island to island,
but it sounds a bit stressful.
Has anyone already tackled this route?
I’m currently looking for a bike to do my first bike trip across France, with the ultimate goal of cycling through Latin America. I’ve got a lot of questions and I’d love to hear if you have any answers or advice to share.
First off, I’ve been through this before with hiking. I want to get top-quality gear right away. When I started hiking, I ended up buying everything three times—first beginner gear, then intermediate, then expert, etc.
For biking, I’d prefer to skip that process and invest right now in a bike that could ideally handle Latin America.
I’ve set a total max budget of around 5000 € (roughly 4000–4500 € for the bike and the rest for accessories: panniers, helmet, cycling shorts, etc.).
So, I’ve got quite a few questions:
* I’ve read in several places that some people recommend buying the bike directly in Latin America. Since I need a first bike to train in Europe, would it be better to buy an entry-level bike in France (and sell it before the big departure)? Or is it preferable to start right away with my final bike to get used to it? Is buying it there just to save a bit of money?
* For a long-term trip (around six months) in Latin America, is it better to go for a gravel bike or a mountain bike?
* Should I buy a new bike or a refurbished one? Even more so given that I’m planning a long trip—could a refurbished bike end up causing more breakdowns?
If you have any advice on models, technical features to prioritize, or recommended sellers or resellers, I’d love to hear it. I’m a total beginner—I’ve only just started watching videos and reading up on the subject, and all the technical specs are new to me!
Calling all travelers.
We’ll be landing at Lyon Airport and want to bike to La Verpillière train station (with panniers and camping gear, etc.) to catch a TER to Voreppe.
What’s the safest route for this bike trip?
Thanks in advance
hi,
I'm planning a recumbent bike trip from the Pyrenees to Greece. On the EuroVelo 8 route, it doesn't specify the path through the Alps.
Are there any experienced cyclists here who can tell me where they go to avoid climbing too high?
Also, is there another traveler/bike forum better suited for broadening the responses?
thanks
