Pop, Cover, Roll:
Most folding bike covers are either too complicated or too time-consuming to use several times a day. The BYB isn’t just easy to fold and trolley, it’s also extremely easy to cover—simply grab the PopCover and you’re ready to go.
Small apartments and commuter bikes don’t usually match. Great news! The slim, small BYB fits just about anywhere—behind doors, under desks, in your closet. In fact, the BYB is a perfect fit for standard cabinets so whether you’ve got one, or more, the BYB will occupy minimal space in your place.
Ready for Departure:
Ever wished you could ride your own bike on vacation? With BYB, you can go from riding to packed bike in 60 seconds. The BYB makes air travel a whole lot simpler: just fold your bike and pop it into its own custom-designed AirPorter Slim suitcase—no disassembly required.
