Our team of product designers based at the B'Twin Village in Lille is continuously working to make cycling more comfortable for our users. Our obsession is to create products that meet the specific cycling needs of our users and eliminate hindrances to a good cycling experience.
We then test our products in the field, as we are convinced that only by subjecting them to real world conditions, like the ones you experience on your bike, can we continuously improve our products.
