This is the folding bike for quick commutes to and from work. Nothing serious and maybe connecting with some trains or buses in between. The bonus is you have a rolling carrier to take the bicycle along with you when it’s folded up. The Link Uno Trolley combines the simplicity of a single speed bike with the practical convenience of a rolling suitcase. This makes it extremely easy to roll the bike around when folded – on a train platform or into an office.
