Good news, it seems that there will be no usage charges for the day of the launch! I have received this email from TFL Barclays Cycle Hire :
Thank you for becoming a Barclays Cycle Hire pioneer. Today you have either used, or joined, the scheme. We are very keen to learn from your experiences and would welcome your feedback at email@example.com
As a way of saying thank you for your support we have agreed that no usage charges will be incurred by users today.
Set out below are some top tips which we urge you to read to ensure that your future use of the scheme is ever more enjoyable.
When you undock your bike,don’t forget to remove your key from the key slot before you set off.
When you return your bike, wait until the light turns green to ensure you have successfully docked your cycle and completed your journey – remember – make sure you get a ‘green light and click at the end of every trip!’
If you have yet to activate your key, do remember to go online and click on “sign in” to activate it – otherwise you won’t be able to hire a cycle.
Look after the scheme – it belongs to London and Londoners. If you see someone vandalising the bikes or docking stations please report it.
