Some of the Barclays Cycle Hire bikes will even be wearing their own poppy, as the usual branding space will be replaced with poppy stickers.

The initiative is part of London Poppy Day, raising money for members of the British Armed Services, past and present, and their dependents. Volunteers will be collecting donations at stations across London tomorrow, and look out for several bands playing in Central London locations including Canary Wharf and Leadenhall Market.

London will mark Remembrance Day with special services and events on and around 13 November 2011.

Londoners can now register as members for the Mayor’s flagship Barclays Cycle Hire scheme. The bikes will be available to members from next Friday, 30 July.

The Barclays Cycle Hire bikes are located at docking stations throughout London. The first 30 minutes of your ride is free but you’ll need to be a paid-up member to access the bikes in the first place.

A membership key costs £3 with membership costs at £1 for a 24 hour membership, £5 for seven days and £45 for an annual membership.

The Mayor of London, Boris Johnson said:

“I call on Londoners to sign up and become pioneer members of this fantastic new addition to our transport system. I know that in time our scheme will become a new London icon and enable many more people to cycle in our magnificent city. I look forward to seeing cycle hire and superhighways working in tandem to make London a cyclised city.”
