How long will it take you to get banned? Triumph, you mentioned the inspired, there are alot of people getting into the 24" side of trials, the Geo of the 24" bikes tends to be far less trialsy than the 20" and 26" bikes. This means that the bike will be easier on your back for one and allow you to do a variation of things, the bike will be perfectly capable of trials, not so much as the pure trials bikes but good enough. And it wont mind to much about being thrown around on ramps and spinning about like a mad thing. Again as i said earlier personal preferance best thing would be to watch videos and get out anf ride some peoples bikes.
