On 25, 26 and 27 July 2025,the banks of the Aveyron à Cos (commune of Lamothe-Capdeville) will learn à vibrate to the rhythm of an exceptional anniversary. The Rock’N Bike Festival is blowing out its 25 candles and promises to celebrate this quarter-century with a memorable weekend of engine revving, rock dances and legendary conviviality. A unique event in Greater Montauban that perfectly embodies the spirit of liberty and sharing in French motorcycling culture.


Over the past 25 years, Cos Rock’N Bike has established itself as one of the unmissable events in French biker culture. What started out as a gathering of passionate friends has become a national event that attracts visitors from all over the region. The authenticity of this event lies in its ability to have grown while preserving its original character: that of a grande fête populaire où mélangent all générations and all passions.
Imagine yourself arriving in Cos on a beautiful summer’s morning. The green gorges of the Aveyron stretch out before you, creating a natural amphitheatre of striking beauty. The murmur of the river mingles with the rumble of engines converging from all sides, creating a unique symphony that heralds three exceptional days. This prepared site offers a striking contrast to the effervescence of the festival. On one side, the peaceful nature of Aveyron with its changing reflections and its lush vegetation. On the other, the deacute energy of a festival that transforms these bucolic banks into a giant playground for two-wheeled and rock enthusiasts.


The biker spirit in all its splendour. From the first few hours, the site is transformed into a veritable living motorbike encyclopaedia. The rides organised criss-cross the picturesque roads of Greater Montauban, offering participants the opportunity to discover our territory from the privileged angle of the motorcyclist. These collective escapades create a unique bond between participants, united by the same passion for the road and beautiful landscapes.
The free-style and stunt demonstrations transform the space into a spectacular arena. The riders push the limits of motorcycle acrobatics to the shrieks of admiration from the audience. These moments of pure adrenaline alternate with presentations of the show bike, a veritable défilé of mécanic masterpieces where each machine tells the story and passion of its owner. Originality takes pride of place. The tractor mower races add a note of dirty humour; which is what makes Cos Rock’N Bike so charming. This zany comp, where spirit counts as much as performance, perfectly illustrates the festival’sgood-natured philosophy: having fun above all else.
