Nah of course not, you could do that stuff on anything from a BMX to a full sus downhill rig, well you know what I mean- backhop to drop and 270 to drop etc might be a little awkward on a 9" travel rig but you could do it on any trials bike. Basically, 24" tend to be quite stereotyped into only being used for 'shit BMX' which is kind of what they're designed for. However, I just wanted to show that they can equally be used in the woods and what would be considered 'proper' street trials (TGS without the T) combined with a bit of more BMXey oriented stuff... as I said, just something a little different
