One of the best parts of arriving in a new port of call is the opportunity to go exploring—whether you’re looking for a place to get some food and drink, a secluded beach where you can kick back or somewhere to provision for the next leg of your journey. And what better way to do all that than by bicycle? But bikes are big, and space onboard is limited. Enter the folding bike—the cruiser’s best friend. Here is a selection of functional folding bikes. Grab one and stow it onboard for your next cruise. You’ll be glad you did.
