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).

Congratulations to the winners! Zoe Goulding from the UK has won the limited-edition Tokyobike. Hamish Ramjee from South Africa, David Roditi from the UK and Esme McCrubb from the UK have all won an AC x Tokyobike backpack.

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.

A wide zip opens at the top of the unisex backpack, which also has top handles so it can be carried like a briefcase.

AC x Tokyobike backpacks are available in three colours and have a retail price of £145.

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 Tabernacle Street, EC2A 4BA.

Three other winners will receive either a blue, a grey or a yellow backpack, which will be shipped internationally.

London-based Ally Capellino's accessories launched in 2000. In addition to its international stockists, the brand has three London shops, and ongoing collaborations with the Ace Hotel and Tate Modern.

Founded in 2002, Tokyobike designs bikes for the city that are light to ride and have an emphasis on comfort over speed. Its first shop opened in Tokyo and the company now has stores in New York and London.

The brands are celebrating the launch of their collaboration at Ally Capellino's Marylebone shop on 23 March 2016 at 6:30pm. Japanese snacks and beers will be served courtesy of Asahi, with a DJ set by The Stinking Bishop.

Entry is free and spaces can be reserved on Eventbrite.

This competition is now closed. Four winners will be selected at random and notified by email, and their names will be published at the top of this page. Dezeen competitions are international and entries are accepted from readers in any country.
