Cyclists were given a helping hand when an expert carried out free maintenance work on their bikes.
Mike Wood, of the Bike Station, was in the city centre fixing and servicing bikes free of charge.
The service is funded by Dundee City Council to encourage green commuting.
The Bike Station is a registered charity which also recycles donated bikes, sells them at affordable prices and then uses the proceeds to help people across Scotland get in the saddle.
Based in Perth and Edinburgh, pop-up events are held in Dundee regularly. The charity is in the process of setting up a permanent Bike Station in the city.
The next pop-up will be in the city centre on Wednesday.
