TRIOBIKE CARGO S The sports version of the Triobike cargo has a Gates belt-drive that ensures an extremely smooth and comfortable ride. Compared to a conventional bicycle chain, the belt is more silent, cleaner and requires less maintenance. The Triobike cargo S has a lightweight and incredibly strong alloy frame but is even faster than the standard cargo model thanks to some upgraded components – Shimano Alfine 11-speed gear group, hydraulic Shimano disc brakes and Schwalbe tyres.
