Doesn’t look like your average GP, does he? Certainly the screwdriver and the spanner would worry me if my doctor whipped them out. The mad glare doesn’t help either. But more calmly now. Fear not. Dr Bike is returning from his winter sleep. He reckons that by April it will be safe to come out from under the covers. He will be under Peckham Arch on the first Thursday of every month and on Quietway 1 near the crossing on Dunton Road every third one. On the second and fourth Thursdays, he rests.

The series starts under Peckham Arch because there’s shelter against early April rain. Working on site will be one ace professional mechanic, two amateur but brilliant volunteers and an assortment of people handing out chat, maps, info and keeping the queue in order.

The mechanics tighten brakes, sort out clicking gears (aka indexing, I’m told), pump up tyres and give wise advice (“clean that chain”, “I would buy a new tyre”, “needs new brake blocks”). It’s all free and everyone is welcome. If anyone tells you we charge, they are confused.
