Looking for a men's hybrid bike

Hi! Is anyone thinking of selling a men's or unisex hybrid bike, medium frame (I'm 173 cm)? Main use would be for getting around town, shopping with occasional light off-road use (family bike trails) so I'd prefer something lightish but with tyres not too thin and possiblity of rack and mudguard fixing. Please email  me if you can help. David, david.solomon314@gmail.com
