All are welcome on this free family-friendly Lambeth Cyclists Neighbourhood Ride taking a couple of hours to gently explore the Waterloo and Vauxhall area.
If you email that you're coming before Thursday 18 October you'll get a free bag of goodies from Barclays and free back-up lights from Lambeth Council.
To register just send an email headed Oct 21 with the names of those coming along to email@example.com . It's fine also to just turn up on the day, but there's no guarantee you'll get the lights etc.
The ride will mainly be on quiet back streets and you will see plenty of famous sights, from the Houses of Parliament to the London Eye.
There are also loads of quirky facts and unusual places along the way.
The ride will finish at 4pm back at the Garden Museum.
