At OLSEN BICYCLES HQ, we like riding all year round, so we have extensively tested Gates Carbon Drive BELTS, Pinion GEARBOXES and Singlespeeds. This turned into a quest to make the perfect British weather all-terrain bicycle for riding and training all-year round. See our shop tab for pricing and items to purchase. The rest of this website is the pictorial journey of our development to make bicycles that are reliable and functional in the most adverse weather conditions in the world... ENJOY!
