With this thread in mind: http://singletrackworld.com/forum/topic/how-many-bikes-did-you-test-ride
...if you didn't test ride many bikes what was it that motivated you to buy the one you did? Was it price, reviews, looks or something else?
The last 3 bikes I bought (cross, road and hardtail) were all bought on the basis that, at the time I wanted them, they were the best bargains around. Next time I'll be testing loads.
