9to5 bike is a 20” wheel size urban utility bike designed to fold into a compact form, for easier transport and storage.  When folded, it can be more easily carried on public transportation facilitating bicycle commuting.
 

In many cities, including Budapest, regular bikes are not allowed on the subways in rush hour. The suburban train might also be too far to walk but the bus service is sparse or erratic. Now, more and more people are using folding bikes for multi-modal transport: cycling to and from the suburban train station and avoiding the feeder bus.
 

The frame quickly folds to fit wherever you need to go: on the train, in your office and more easily stored in compact living quarters.
 

9to5 is a chainless bicycle equipped with Gates Carbon Drive system uses toothed synchronous belt and lightweight sprockets providing low maintenance and lubrication-free benefits.
 

Derailleurs cannot be used: no gear shifting. A single speed requires little maintenance and keeps transmission loss at a minimum.
