Do 29ers "work" for larl folk? The reason I ask is I saw the bike pictured below on another forum. Its a very nice build but I cant see how the rider would actually be able to ride it properly - the bars are way higher than the seat to start with. Is there a cut off height where a 29er is too big? Can you actually ride them if you're short, or is it a case of just holding on and hoping for the best?
