About me

I've always liked to be reasonably fit and when my knees complained about running I moved to cycling as my main form of exercise. I've gradually learnt more about bicycles such that these days I can call cycling and tinkering with bikes a hobby with some of my recent bicycles assembled from parts to suit my requirements and others extensively customised.

When I am not cycling then I'm often thinking about, and sometimes implementing, ideas for reducing the running cost of my home. I've got solar panels, batteries and a heat pump with the main remaining challenge being how to reduce winter heat losses from a 1970's house and how to stop it becoming uncomfortably hot in summer.
