Hi, first time posting here and hopefully not the last. I've decided to take the plunge and buy my first bike since I was about 12. The bike I got was the Carrera Crossfire 1 which is a hybrid. Admittedly I kinda got it on a whim and I'm starting to regret it as I don't think it'll be able to take my weight. My friend suggested getting better tyres if I have any problems. I haven't got it yet but I should get it tomorrow (ordered off the internet). Is there any other suggestions you can give me? By the way i'm about 6'2" and about 340lbs (yeah, I got the bike to loose weight. Hopefully it should work well with my diet).
