"Spark Free is not selling bike equipment, we are creating dreams”

And I really believe in it: with the blog and vlog I am trying to make you reflect, but even more I want you to even more enjoy riding a bike. But with the equipment you can actually feel, smell and carry with you a part of the dream.
