Hi, Just looking for some advice on purchasing a bike. Im a beginner rider and intend to do the cairns to cooktown bike challenge (350KM over 3 days - mostly bitumen) in 12mths time. So looking for a suitable bike. Im leaning towards a hybrid/flat handle bar road bike. I have the opportunity to buy a secondhand giant nrs xtc 3 mountain bike for $400 in relatively good condition. Ive also been looking at the Avanti Aria 2014 brand new for $699. Alot of people have been recommending the giant however im hesitant as its secondhand and unsure if a mountain bike would be suitable for a 350km ride. Thoughts?
