John Buckley, a National Cycle Instructor with Hampshire Cycle Training, offered Whitchurch residents an opportunity to have their bikes road-tested.
His stand outside the Town Hall was doing a brisk trade on Saturday morning.
"I helped John pump up a tyre, and watched him advise people about brakes, cycle maintenance and a range of other issues."
Some residents brought out old bikes from the shed that had not been used for some time, and then rode them home.
"I congratulate John on his initiative in promoting cycling locally."
