Bicycle provision is poor in High Kingsdown, which was built just after the peak of enthusiasm for car transport.
In the garages, rudimentary provision for bike storage has now been installed. Use a D-lock, otherwise your bike may get stolen - miscreants are always lurking.
Residents of the houses are in an easier position, as they can secure bikes in their gardens. But visitors to the estate have no way of securing their bikes.
Lifecycleuk provides free training, useful for those (like me) nervous when turning right or on roundabouts. Or new to the UK!

Planning your route:
Good paper cycling route maps produced by Better by Bike, which are excellent at local level, can be got for £1.50 from the Bristol Tourist Information Centre next to the Watershed (but are sometimes out of date).
It helps to use Google maps to wander around before making a journey. You can see what low-traffic routes are possible, but of course it doesn't show cycle-only routes.
