The world's first cash machine was installed at a Barclays branch in Enfield in June 1967, and a blue plaque marks the spot. Enfield has another claim to fame for riders: the Royal Small Arms Factory at Enfield Lock made the Lee-Enfield rifle, and the town's name passed to the Royal Enfield motorcycle company, whose bikes are still built today, though now in India. The factory site has since been redeveloped into housing around the old buildings.
This finish lies in the southern part of the borough, near Edmonton and Bush Hill Park, a district of terraced streets, parks and busy main roads. The Lee Valley, to the east, is a long green corridor of reservoirs, marshes and nature reserves, running north from London, and it is a surprising escape from the city.
Forty Hall, to the north, is a Jacobean manor house with gardens and a park, and Trent Park, nearby, has woods and lakes. The New River, an artificial waterway built in the early seventeenth century to bring fresh water to London, winds through Enfield, and its banks are lined with paths.
Coming back from Cambridge and the Fens, the final stretch follows the A10, a busy, fast road with speed cameras and heavy traffic. The roads into Enfield are congested at rush hour.
Fuel is plentiful along the A10. If you have a Royal Enfield in the garage, it is hard not to smile at the thought that you have just ridden it home, more or less, to the place its name came from.
