One more thing if this is the bike for you go for the one with the suntour seat post, it's only £40.00 more and you can't buy this seat post for £40.00 anywhere else, and it will help soak up the bumps.
Best if you give woosh a bell, they will give you all the info, I don't have one of there bikes, but from what I read on here, the big bear is a good bike with lots of grunt to go up the hills.
Look on here www.bike-discount.de for the suntour seat post, it's £43.39 plus £4.83 shipping cost.
I got one from them a few weeks ago and it takes about 5 days to turn up
I don't think you can find it any cheaper.
