In a world in which we have come to expect our gadgets to be small and compact yet deliver the benefits of the full size model, Pacific Cycles' IF Mode fold-up bike is unlikely to disappoint. The IF MODE combines a number of features to optimize fast folding into a compact footprint including a single sided fork and rear stay (on opposite sides of the frame), folding handlebars, integrated stem and front fork and even folding pedals. The clever twist - literally - is the patented, single-action, automatic folding mechanism that requires no tools or removal of parts and automatically guides the wheels together. Once folded, MODE becomes a wheelable package complete with in-built handle so that you don't have a dead weight to lug around when you swap pedalling for perambulation.
