I also use Valenbisi and paid for the 30 euro per year subscription. The first 30 minutes you ride are free, but after the 30 minutes, I would need to pay two euros, and if I use the bike for more than 24 hours, I believe I would need to pay around 100 euros. I usually don't take more than 15 minutes on the bike because everything is close, and if I am going somewhere really far, I would just take the metro or the bus.
When I am riding my Valenbisi bike, I feel more connected to the people and nature. As I bike home or bike to meet friends, along the way, I see many trees filled with ripe oranges, friends walking together and owners walking their dogs; I feel connected and content that I get to see many different lives in the same city. Riding a bike around the city gives me serotonin. I see old buildings, the beach and the city center. Riding alongside the beach gives me peace and I feel right at home.
