I think I'd like to get an audax sometime soon. I like the idea of going fast but as I have a small son will also spend quite a lot of time meandering at a reasonable pace, carrying lunch whilst screaming at him to watch out for traffic.
Can anyone recommend a reasonable bike make/model? I'm looking to spend maybe 600 quid or so. Is this realistic?
Advice and opinions greatly appreciated.
