I have never seen such a wonderful museum, have a look here. They have more than 1000 British bikes and at least 800 are on display at any one time, the others are then maintained and every bike they have is a runner!
No other museum I have ever visited offers so much. The bikes range from the late 1800s to the present day and my goodness they are ALL worth seeing! Every bike they have is a runner so hence the drip trays, and they are really well described and grouped into military, race, RAC/AA, three wheelers etc and so make wonderful viewing.
DO visit and I promise it is well worth your time!! There is even a canteen upstairs offering excellent food at a great price.
