The Israeli designer who created Flex gave it a holistic design, made of carbon fiber, that reduces visual noise. It looks like a bike that’s from the 1950’s, but with a modern-day twist. We love strange designs that play on different time periods. The designer said, ‘‘flex’ is a compact city bicycle. the intention of the design is to create a bicycle that has a whole form, as opposed to a normal bicycle which has many parts that are completely separated in terms of aesthetics.” It’s clear he had aesthetics in mind when he built this bike since it’s pleasant to look at and very minimal. He said, “I combined the back fork with the chain cover for one element, which reduces the visual noise and creates a new iconic look.” With this bike, the brakes are in the back, used with reverse-peddling, and it has narrow handlebars (Design Boom).
