Bike shops (second hand)

Can anyone recommend good shops where to look for a bicycle?

Preferably a second-hand shop or so, as I don't know how long I am going to stay.

I've heard stories that cycling in Malta may often be a rather bad experience due to mad drivers and narrow streets - is it that bad in reality? As for the heat... no need to mention it :)

Thanks!

yes it is - many do cycle but it is dangerous due to bad roads and seriously bad drivers.

try the cycle hire shops they often have used bikes for sale
