More than 120 cyclists of all ages pedalled through scenic routes as part of the Ticket to Ride Events hosted by Ealing Council.
A total of 123 people - led by marshals - took part in the free bike rides from Northala Fields and Brent Lodge Park in Hanwell on Sunday (June 28).
The routes went along roads, the canal towpath and through parks, and this year new routes were covered, taking in some of the scenery to the north and west of the borough in Northolt, Greenford and Southall – areas where fewer people cycle.
Council leader Julian Bell and cabinet member for environment, transport and leisure, Councillor Bassam Mahfouz, were among the participants.
Cllr Mahfouz said: "Despite a bit of rain in the afternoon it was great to see so many people turn out to enjoy these wonderful rides.
"We're committed to encouraging people to cycle more and get active and these events are a fantastic way to get people of all abilities to explore our beautiful borough by bike.
"We're keen to help people enjoy this fantastic, healthy and fun form of transport and we are also supporting a series of guided rides for women this summer which I’m sure will prove equally popular."
