Competition: Dezeen has teamed up with Tokyobike and Ally Capellino to give readers the chance to win a special-edition bicycle and one of three rucksacks (+ slideshow).
The limited-edition Ace Hotel bicycle in blue steel
Designed for the Ace Hotel chain, the limited-edition Tokyobike is available in four matte finishes: blue, juniper, vermillion and gold. Mudguards, racks and baskets can also be attached to the frame.
The bicycle features a leather saddle and handles detailed with pre-punched holes and laces that can be tied like a pair of shoes. The standard retail price is £680.

British accessories label Ally Capellino has also partnered with the cycling brand to create the AC x Tokyobike backpack, designed for cycling in the city. Ally Capellino has updated the Frances backpack with cycling-friendly features, including a proofed nylon exterior, a reflective strip, and a loop for a cycle light. Inside a padded sleeve fits a 13-inch laptop or tablet.

The winner of this competition will receive an Ace Hotel bike in steel blue with size on request, subject to availability. They must be able to collect the bicycle from Tokyobike's London store, 87-89 Taberna...
