If it has two wheels and pedals, it is good to go. Many of the current members did their first triathlon on a mountain bike. Bikes can get pretty expensive, so you might as well make sure you like the sport before you invest in a $2,000 carbon-fiber frame. If you don’t own any kind of bike, many of our older members own more than one and are often willing to loan one out – if you ask nicely. Once you’re ready to buy a bike, our veteran members are happy to talk you through the different types, brands and price ranges of bikes.
