Fair to say I spend quite a lot of time riding bikes & tinkering with bikes...
Recently stumbled on following equation - which is totally spot on:
Number of bikes you need = n + 1
where of course n= Number of bikes currently owned :o)
Currently in my ownership; n = 3 (& yes all 3 in regular use)
Looking forward to seeing more on BBC soon...
