The GT20

The Great Crossing of Corsica by Electric Bike

Le GT20 : The great crossing of Corsica by electric bike !

The bike now has its GR20! With more than 600Km crossing the most beautiful landscapes of Corsica, between turquoise waters and snow-covered peaks, and a high point at nearly 1,500 meters, the GT20 is one of the most beautiful cycling routes in Europe… and also one of the most challenging.

Fortunately, the technology of the electric bicycle coupled with the network of Bosch charging stations along the route, make this Grande Traversée de Corse, with zero carbon emissions, accessible to everyone regardless of age and physical condition.

What’s the GT20 itinerary ?

The GT20 crosses Corsica from north to south. The 600 km route starts from Bastia, in the north-east of Corsica, then crosses the Cap Corse to take you to the west coast of the island of beauty, to discover Balagne and its promontory villages. The GT20 then continues along the coast towards Galeria, the gulf of Porto and the creeks of Piana, listed as a UNESCO World Heritage Site. From Porto, the itinerary then takes you to the centre of Corsica by crossing the Spelunca Gorges, the Aitone forest and its natural pools before climbing the Pass of Verghju, the highest road pass in Corsica perched at an altitude of 1,478 metres.

From the Col de Verghju, the GT20 then takes you to Corte, the historic capital of independent Corsica and its Restonica valley and mountain lakes.

From Corte, you continue south through the passes and villages of the interior towards Venaco, Ghisoni, Zicavo then Zonza and its aiguilles de Bavella, before descending the Ospedale forest to end your adventure on the heavenly beaches of Porto-Vecchio and Bonifacio in the extreme south of Corsica.

Is GT20 difficult ?

Why is GT20 the most challenging cycling route in Europe ?

With 600Km of route, a peak at almost 1,500m and 9,500m of difference in altitude, the GT20 seems at first sight addressed to expert cyclists.

On a classic bike, the itineray is reserved for high-experienced cyclists with a good physical condition and high endurance are required to be able to pass the dozens of passes that make up the Corsican mountains. Agencies specialising in cycle tourism in Corsica offer to organise your GT20 road bike tour with you.

With an electric bicycle, the GT20 becomes accessible to everyone. The most important is to choose electric bikes with good power to climb the passes and a large autonomy. An effortless crossing of Corsica by bike… It’s as if you could do the GR20 while flying!

The GT20 is therefore a very difficult cycling itinerary that e-bike technology makes accessible to everyone. An amazing and unique itinerary, the majority of the route crosses the protected areas of the Parc Naturel Régional de la Corse.

For hiking enthusiasts, the GT20 also offers many connections with the GR20. 

The Bosch eBike charging stations on the GT20

In order to never run out of battery, AppeBike has partnered with Bosch to launch the world’s first network of Bosch eBike charging stations. A pilot project of charging stations for users of electric bikes powered by Bosch.

Each PowerStation offers six secure key lockers to safely recharge your battery. The Power Stations are compatible with all Bosch batteries, such as PowerTube or PowerPack.

Remove your battery and recharge it free of charge in one of our new PowerStations. Always keep the key to remove your battery with you!

The Bosch eBike Systems Standard Charger 4A will charge your battery while you enjoy lunch, an activity or just a break.
