Five (although one them is technically hers, but I paid for it and built it up, so therefore its mine!).
SX Trail
BFe built up as a jump / mucking about bike
Allez Sport (first new bike in ages and gets loads of use worringly)
Chameleon (‘hers’)
Old Cannondale Beast of the East (not sure of the year)
Keep thinking that I’d like another DH bike but it wouldn’t really get that much use and would cost me a fortune. I often get tempted by bargain frames / bikes on retrobike. Normally thinkgs that I lusted after when I first started riding but could never afford. So far I’ve managed to resist.
