Go to youtube and search trials bike. [I]Then[I], I want you to search some of the names/faces of bmx: Nigel Sylvester, Ian Schwartz, Edwin DeLaRosa, etc. There should be an extremely noticeable difference.
When I look at the frames of both, the WTP bike is a more traditional frame. The Inspired, that has a unique frame angle to it, top tube and seat stays are virtually on the same angle/line from head tube to bmx rear wheel stays. Maybe because the Inspired has a 24" wheel ? I watch the bmx stuff on tv, even You Tube, it seems those guys use a variety of equipment and that one is no better or preferred than the other, beyond what the sponsor provides ? The bikes are set up with the equipment that makes them most competitive at what event they're competing in. But the frame geometries available are used in all events.
When deciding between trials and BMX, you really have to think about what you feel you really want to be doing on a pair of wheels, because there's a huge cost difference that'll really hurt the pocket if you decide to switch later. I mean, its ok to switch and change your mind, don't get me wrong, but it really is going to chip away at the old bank account. And fuji, the bikes really are set up for two different styles of riding. I mean you could use the Inspired for bmx if you really tried, but the frame geometry would really throw you off and make that more difficult than a bike that was actually designed for it.
Well the difference off the virtual eshowroom floor is about 8 British pounds between these two bikes. To me it's a matter of choice, going with a 20" or 24" wheel. I mean, assuming the bike is even used for any of this after a few rides. The jumps & stunts can be done on either, the video footage proves that much. If it ever gets to competitions, certainly the bike sizes are classed for event. I agree there are designs that make it easier to perform, but I've also seen video footage of cyclists being able to do what most of us associate for bmx with mtb. And the differences in hardware aren't something that one can't overcome. Here are a couple of videos demonstrating that either frame style and bike can be used.
Actually the only thing that is missing is the peg stunts. Outside of that there really isn't that big a difference ? Location is different, but the stunts themselves could be attempted or performed by either bmxer(s) ? And I think that's what Danny MacAskill demonstrates that the trial bike is capable of with an expert rider. I recall seeing a video where a guy does that kind of stunt and trick work on an mtb, which is even more remarkable when I think about it. The MacAskill video, he actually fails trying a stunt on the power box & fence. These are stunts that one has to practice and have the gift to be able to perform them successfully for sure. Otherwise it's quite a painful failure, even can be expensive. MacAskill pounds out a bend on what appears to be his wheel after a fail.
They're built for different styles of riding. Never said that you couldn't ride one bike for the others style and vice versa, but that's not what they're designed to do. They're made to be ridden for their own different styles of riding. Otherwise, you would see a lot more videos of guys doing double/trip whips on trials bikes, or guys jumping from trashcan to trashcan on city streets on just their back wheel on a BMX bike.
