No but I have ridden a few if them (the alu and the carbon ones)
Basically they're brilliant VFM and ride well. Unless you care about the brand or you really know what you're looking for in a road bike then the Boardman will always be a good choice.
My only real issues (and these are very picky and minor) are that I don't like the SRAM shifters (but that's personal preference – others seem to like them), the saddle is very narrow and seems not to suit many people IME and finally, the handling is a touch more neutral than I like.
EDIT – ignore all the above. I was talking about the road bikes 😳
I have ridden the FS one though and that's amazing for the money – again, maybe a little too neutral for my preferences but that's really being picky for the money.
