Thanks nickswan1. I am a bit closer to understanding gear ratios now with all the advice and the chart. I will try out some freewheels and chainrings and let you know how a get on

I have just had another look at my set up and it seems I am running 42/16

Think I will try out 45/16 and 42/14 to see what the difference feels like. 14 tooth freewheels arn't too expensive anyway
