where can I find in ebay I need it tough and for riding it over rocks and from sidewalk to other I mean it should be strong enough contains some shock absorbers I need the brand and size for me I am 34yrs and how much it cost the used one and the brand new.thank you in advanced.
btw. Your bike size is not determined by age! and you will get such a multitude of answers,(eg used/new =£5 / £2500) as to the brand preference????, you just as well go to your local bike shop and see for yourself!
Ask them and try a few hardtail MTBs - buy one you like and that fits!
