While hiking, walking or cycling, I learned to pay attention to the weight of my equipment. I learned a lot about ultra-light walking sites (MUL) especially randonner-leger.org/. The basic principle: is this equipment indispensable to me? To find the right balance between comfort, safety and lightness. I apply the same principles to bike riding. For […]

Today, Elisabeth Dounon sent me the aluminium profiles machined by the apprentices of the CFAI of Châlon-sur-Saône. Thank you to the young, to their Professor Vincent Daka, and to Elisabeth Dounon! (Read more) These parts that support the solar panels allow the two side panels to slide so as to reduce the width of the

With the prospect of a partnership with the CFAI-21-71, I was today presenting my bike to a group of young apprentices in alternation training. I was asking for their help with the machining of aluminum tubes that support solar panels. As a matter of fact, I had machined aluminum parts for sliding the lateral solar

Throughout this project of creating a technical object, I was able to realize how complex the creation process is, because indeed: many parameters are taken into account (of the order of physics); some parameters are closely correlated (while others are independent); some parameters are the result of a personal choice or a preconceived idea, others

Today, accompanied by Elisabeth Dounon, I visited the training center of the apprentices of the industry in Dijon (CFAI 21-71). For me who loves technology, it was a pleasure to discover their equipment, especially the room dedicated to robotics. Then we considered how the apprentices could be associated with the process of creating the solar

Today, the FabLab Kelle Fabrik organizes a workshop to learn how to program an Arduino module. I was enthusiastic about it. What relationship with the construction of a solar bike, will you object? Well, I had seen that some participants in Suntrip 2013/2015 optimised the recovery of solar energy by orienting their solar panels. So

Two days before this workshop, I had installed the free and free blender software on my personal computer. By discovering the complexity of the interface, I quickly abandoned the exploration, discouraged. And tonight, after 2 hours of discovery guided by the animator of Kelle Fabrik, I almost manage to finalize my project! I can't believe

How will I go about making my solar bike? I do not have an electrically assisted bicycle, I know very little about capturing solar energy … Suddenly, the questions flow in all directions: for electrically assisted bikes: what type of motor? Hub motor or bottom bracket? Motor on the bike or on the wheel of

Today I met Jean-Claude who is a physics teacher in Dijon. I asked him all the questions that had come to my mind on the previous days: How to calculate the energy consumed by the bike to determine the required surface of solar panels? How is solar energy regulated by nature so fluctuating? He enthusiastically

According to Wikipedia, an electric power-assisted bicycle (V.A.E.) is a bicycle equipped with an auxiliary electric motor and a rechargeable battery. Legal definition of a V.A.E. In France, a bicycle with electric assistance must conform to the European Directive EC2002/24 and the French standard NF R30-020 laying down the following general principles: The rated power

This afternoon it was my "first time", my first try with an electric-assisted bike loaned by the gable-on-street cycle shop. It was a very informative outing for a novice like me, my impressions were contrasting: on the one hand, a great satisfaction to climb the coast of vises at an unusual speed, but on the
