okay folks ive almost have got around $1699 AUD towards a new bike but there is 3 models in which i can't decide to get, i like to muck around doing wheelies and small drops and i also like to ride trails and dirt jumping. The three bikes i had in mind were the 2005 Giant STP1, 2005 Giant AC and a 2005 Diamondback BSX pro (the diamondback bike i get for cheaper, it was originally $2100. If any of you own or have riden any of these bikes any information on perfomance etc would be great.
