Because the traditional handlebar basket can only carry so much, this Spanish designed Noomad might just be what you need to carry stuff around. It replaces your front wheel and fork with a pair of tilting wheels supporting a carrying platform.
The installation is also fairly straightforward. The Noomad comes with its own lever that easily attaches to your handlebars.
The Noomad kit starts at $600. Quite steep for some cargo space. What do you think? [Noomad Bike
