I bought this turbo trainer because I can't get out on my bike and I need exercise badly. I was going to get a new quick release wheel but I've got it to fit on the bolts on my mountain bike so haven't had to shell out any more money. It does exactly what I need it to do for a first trainer and I use the gears on my bike for the resistance. The only drawback is that it is noisy, so watching the tv whilst on the bike is out, but with the zen playing my music through earphones it's great, I can't hear it! Cheap enough too!
