Ride & Return, Point to Point

In order to ensure that TrinTrin bikes are always in active service and do not stay idle with the renters during their non-riding hours, users are advised to return their bikes immediately as they reach a hub closest to their destination and, if required, rent another bike for further transits. They can undertake this kind of point-to-point, ‘break-and-resume’ rides any number of times and thus free up their bicycles for people in the wait line.
