Adidas, The Guardian, Levi's UK and Zipcar are among the big name brands that OnYerBikeSeat has worked with in the last six months.
OnYerBikeSeat, itself not yet two years old, produces promotional bike seat covers for marketing campaigns for product and the opening of new stores.
OnYerBikeSeat.com's David Palmer said: "The key role for our covers is raising brand awareness on the streets and delivering a unique and fresh new marketing angle for businesses. We are particularly pleased with the diverse range of clients that is choosing to commission covers from OnYerBikeSeat. Businesses both large and small, from cafes to banks, fashion and sports brands, charities and local authorities."
Specific offers with QR codes or general branding exercises have all featured on the firm's designs, which have the added bonus of practically protecting saddles from the elements while or promoting a product, event or service.
Palmer added: "Virtually any design can be created and can include QR codes, promotional offers and even maps. This flexibility and our 'in house' creative service means that unique, diverse and interesting designs can be made to engage with any customer.
"We are always looking for new and creative ways of pushing OnYerBikeSeat.com and are investigating retail options as well as working with some exciting trade brands."
