We currently use accessories to personalise bicycles to match our taste. We often seek to balance functionality and aesthetics. Bicycle lights are a necessary safety feature which have evolved considerably thanks to the new technologies. Bells are another highly functional safety accessory when riding along two-way city streets. At PROOU we wanted to personalise some of the perhaps more aesthetic accessories like fenders and handlebar grips. We work with two very natural materials that come from trees, namely wood for the fenders and cork for the grips.
