I have found the dates for this years Bike Week.

Britain Bike Week 2011 will take place 18th – 26th June nationwide.

The website is still a bit out of date, but you can send an email to hq@bikeweek.org.uk and they will let you know when it is up date.

Lets hope this year gets at least as good as last year.
