Tony suggested finding someone who does have a bike. And inevitably if they’re keen, they’ll have more than one. And if that one doesn’t fit you, they’ll have a friend who has a bike. And then he suggests just getting out for a ride. Wear a helmet and gloves, and go for it.

The huge tragedy of the UK is that for 31 of past 44 years The Tories and their asset stripping short termism has downgraded our country. Decent housing was turned into an unaffordable asset - we have gone from the second most equal society in Europe ( after Germany) in 1975 to
