I had met him in Pau last summer, he had come to meet the participants of the Sun Trip France 2020 and to see their solar bikes. He was very enthusiastic about this mode of transport, and we had a good chat!
Grégory has made his project a reality: since last fall, he has been traveling by solar bike to the various places where he leads workshops for young audiences. 2000 km traveled to date! This approach is fully consistent with the purpose of its activities: discovery of nature, scientific, sensitive or artistic approach, preservation of the environment … (Find out more on Terra Pitchoun )
Grégory found good listening with Déclic Éco who designed and built the bike perfectly suited to his professional needs.
The Sun Trip achieves its objective: to spread the concept of solar bike!
Leaving Lyon on June 1, the participants in the Sun Trip prologue continue their journey. They went from the Jura mountains to the Vosges mountains, with unfavorable weather: the brave had to pedal in the rain, sometimes the storm, they climbed the Ballon d’Alsace under the clouds! Find them in this video by Sophie Planque and Jérémy Vaugeois.
Bernard Cauquil has the privilege of appearing in this report on the Sun Trip Europe of France3 Auvergne Rhône-Alpes, Bernard Cauquil who totally designed and built this fantastic solar bike, with original and innovative characteristics.
This morning, in Lyon, the start of the Sun Trip Europe prologue was given at the Town Hall, in the presence of the mayor Grégory Doucet, elected officials of the city and the Metropolis, Ferran Tarradellas Espuny, representative in France of the European Commission.
The speeches present the exemplary values carried by the Sun Trip: the search for sustainable mobility to meet climate challenges, a challenge that we must face together within Europe. Mr. Ferran Tarradellas Espuny recalls the motto of Europe: “united in diversity”, this diversity that we will discover and taste throughout our journey.
This motto also reflects the spirit of the Sun Trip, with its values of inclusiveness: a group of people with disabilities participate in the prologue with adapted solar bikes, the Benur , designed by a Lyon company.
The organization of the Sun Trip has published the trailer for the event, with the 5 compulsory passage points for all solar bikes.
The rest of the itinerary is at the discretion of the participants. Some plan a fairly direct route, others announce detours through Sweden. Further on, participants will be tempted to cut through Belarus and Ukraine, while most will cross Slovakia and Hungary to join Romania.
But the evolution of the health situation in each country could shake up the projects …
From my first participation in the Sun Trip in 2017 until today, I have experimented with different configurations of solar bikes.
Here are the basic principles that guided my constructions:
– from 2017 to 2019, I wanted to be able to take my vehicle by train. So I opted for a classic bike associated with a single-wheel trailer carrying the solar panels (which could tilt vertically).
– for the Sun Trip 2020 which was to take us to China, my goal was to be able to have as much solar energy as possible. So I associated my solar trailer (3 panels) with a recumbent bike on which I added a solar roof (2 panels). Thus, I reached the maximum solar surface accepted on the Sun Trip (almost 2.5 m² which corresponds to a power of 500Wp). In 2021, I transformed the trailer a bit.
Here, I have finished a little video which traces my preparation for the Sun Trip since March, with moments of enthusiasm and the vagaries of this spring.

Today, everyone agrees that it is urgent to reduce our CO² emissions. I was just wondering what the differences were in terms of CO² emissions between the different modes of transport.
The answer to this simple question is ultimately quite complex: many factors go into the calculations, starting with the average number of passengers in a plane, in a car.
For the table below, I used the data * published by the European Environment Agency to calculate the CO² emission for a trip of 10,000km, i.e. the distance we will travel during the Sun Trip Europe.
To give yourself a scale of these values, the easiest way is to compare them to the annual CO² emissions of a French person, i.e. 12 tonnes of CO2 equivalent through his travels and his accommodation ( heating, hot water, electricity) for one year.
We can see that by plane, a trip of 10,000 km would increase the annual carbon footprint of a French person by almost a quarter!
N.B .: the approach presented above does not take into account the manufacture of vehicles.
That’s it, one month before the big start, the look of the official Sun Trip Europe jersey has been revealed to us! As always, the jersey is very beautiful, with its shades of blue that evoke the sky and the stars of Europe that cross it!
The Benur bicycle meets the travel needs of people with reduced mobility. Its ramp at the rear allows independent access with a wheelchair and, if necessary, to take a passenger.
Going to work, shopping, taking children to school, going to the cinema, everything is possible with Benur! And thanks to its removable bench, it can also carry heavy loads.
The Benur bike is available in a version with a solar roof, which allows the battery to be recharged throughout the day.

This bike is developed by a company that hosted the Sun Trip on its premises on July 30, 2020.
Obviously, this month of April will have been marked by the re-containment and the limit of 10 km around the home! Luckily, half of my perimeter was surrounded by nature and was quite hilly. It was also the opportunity to discover or rediscover side roads and small forgotten roads … I saw spring unfold visibly, despite an episode of snow and night frost.
By knitting in this perimeter, I increased the distance covered each week. For my longest outing, I managed to do a 200 km lap with 2600m of vertical drop!
April ends with rain! Suddenly, the bike remains in the garage and I take this opportunity to refine the itinerary for this summer and publish a few articles.
While Suntripers design their bikes for long distance travel, other people imagine a more urban solar bike, for everyday use, for family use.
This is the case of the Vhélio association which wishes to promote an alternative to the car. She designed a solar vehicle that allows getting around in a practical, economical and ecological way. The vehicle can transport 2 adults and 2 children, and it has storage space (for shopping and more …).
In addition, the objective of the association is to provide the plans and the list of parts to allow everyone to build their own solar vehicle (VhéliO’tech). The finalization of the design of the VhéliO’tech kits is the subject of a crowdfunding campaign, to be found here .

At the end of March, I took advantage of a period of full sun to restart my solar bike. I was able to carry out 3 outings before confinement, with several objectives:
– test the various modifications or repairs carried out on the bike this winter,
– get used to pedaling again for a whole day,
– test different settings to better manage engine consumption (my average consumption in Wh / km on the Sun Trip France in 2020 was quite high).
Another objective, not the least, was to take advantage of this beautiful spring atmosphere by visiting the Côte-d’Or and the Saône-et-Loire.

Recharge au Lac de Grosbois
In this season, the solar radiation is obviously less strong than in summer, the available energy is about 60% of what it is in July. If during the summer of 2020 I collected around 3000 Wh / d on the best days, here I have recovered up to 2000 Wh / d, which is already not so bad.
The solar charge was increased thanks to the absence of wind which made it possible to ride with the panels tilted at the start and end of the day. But the wooded parts of the course made it difficult to catch the light, even with trees without leaves!
To maintain a balance between consumption and production, I tested different settings in the Cycle Analyst depending on the terrain (maximum speed, maximum power, etc.)
On the first ride, I used too little the battery in the morning. So much so that during the meal break, with the panels perfectly oriented, my battery recharged very quickly. At half-time during the break, I had the feeling of “losing” this precious solar energy which could no longer enter my full battery!
During the next 2 outings, I corrected the shooting by increasing the speed in the morning and therefore the fuel consumption. Downtime is in fact privileged moments of charging when the panels can be perfectly oriented towards the sun.
Overall, I managed to balance production and consumption until 5:30 p.m., then production became too low to cover consumption. And no question of reducing consumption: I had to be home by 7 p.m., curfew time!
The “Breizh Sun Trip” will take place in Brittany from June 27 to July 7, 2021. This tour will offer ten stages, from 60 to 120 km, to discover some of the most beautiful sites in the region, in the cities, on the coast or inland.
About thirty participants are already pre-registered!
Here is an overview of the route in preparation, from Lorient to Saint-Malo!
It was the 3rd great preparation outing for the Sun Trip Europe before the reconfinement.
I was able to enjoy the beautiful landscapes of Côte-d’Or, visit corners that were unknown to me. And I even drove a bit in Saône-et-Loire. It was good to ride in the sun, without fear of miles.
To say that the confinement will soon lock us into a 10km perimeter around our home!
Tour: 232 km
Elevation +: 1590m
Consumption: 2540 Wh
Production: 2010 Wh
The first outing being conclusive, I wanted to continue my momentum and exceed 200 km during the day. The sun was 100% with me, but the solar power is obviously less in March than in summer (between 60% and 70%). I wanted to see the amount of energy produced by the panels under these conditions.
Consumption: 2130 Wh
Production: 1720 Wh
In spring 2020, the departure for China had been postponed to 2021. Unfortunately, the global health situation still does not allow such a destination.
It is the reason why the 2021 edition of the Sun Trip will take place in Europe! We all hope that spring will bring an improvement in the health situation and a relaxation within the European area.
After a prologue between Lyon and Brussels in the first half of June, the big start will be given in mid-June in Brussels for an arrival in Lyon in less than 100 days. Participants will have to go through 5 compulsory check-points:
– Stockholm in Sweden,
– Constantza in Romania,
– the Passo dello Stelvio in Italy,
– the Pico del Veleta in Spain,
– Porto in Portugal.
Between these compulsory passage points, participants are free to choose their route.
Some countries are essential: Belgium, Netherlands, Germany, Denmark, Sweden, Estonia, Latvia, Lithuania, Poland, Romania, Italy, Spain, Portugal.
But in Eastern Europe in particular, many alternative routes are possible between Ukraine, Belarus, Slovakia, Hungary, Bulgaria, Serbia, Croatia, Slovenia, Austria …
Cycling as therapy is an objective pursued by the Grenoble-based association Vécolo, which promotes a return to sports. To encourage people to resume physical activity after a long battle with illness or medical treatment, she organized a challenge on the road to GT20 (Grande Traversée). A bike ride through Corsica, which took place in 8 stages from Bastia to Ajaccio, with nearly 500 kilometers covered for more than 8,000 meters of vertical drop.
In total, 16 participants took part in this first edition, which was held from September 19 to 27, 2020. All were equipped with an electric bicycle, in order to offer more autonomy and mobility to everyone, everything. by enhancing self-esteem.
Beyond physical and mental performance, this challenge is a vector of social diversity. The different stages were punctuated by moments of conviviality, which united the whole group.
Interview with Jean Bizet, member of the association, and Christophe Bayard, project manager.
We plan to follow a route developed according to the relief and the weather forecast. And during the day, we often choose other routes because of a landscape, a meeting, depending on the mood of the day or sometimes fatigue … The route is invented each day!
August 10, from Albertville (Savoie) to Bois-d'Amont (Jura)
Unlike previous editions of the Sun Trip where my solar bike could get on a train (TER), this year I have to return by road.
I'm not going home by the fastest route, I'm going to go up to cross the Jura where I will find calm roads and landscapes, and too bad for the drop! Or rather, so much the better, because it is the height differences that provide beautiful panoramas!
Génial : la piste cyclable est à la porte du camping !
