Here are a few links to organisations and companies of interest.

St Nicholas Fields: An urban nature reserve and environment centre, a mile from the centre of York. 24 acres of nature reserve including meadow, tree trail and beck that is home to kingfishers and water voles. Also home to a sustainable recycling collection service using an electric vehicle and pedal powered trikes.

Bike Rescue: A Community Interest Company who rescue and refurbish unwanted bkes to give them a new lease of life. They also run the Hub Station in central York providing bike parking, shower and changing facilities, servicing and repairs and bike and accessory sales. Bike Rescue provide me with a lot of my raw materials, from their stock of used tyres and tubes.

Your Spokes: Custom wheelbuilding and spoke cutting service in York. Whatever hub or rim you're after, he'll build it up for you!  Also a source of raw materials for my work.

Velo Vision: The cycling magazine that covers all the stuff the others don't. From utility cycling and touring to recumbents and the frankly unusual.
