That Next bike is not really suitable for the trails at Alafia, it will fall apart quickly. What it is good for is getting out there, riding the green (beginner) trails and deciding if this is a sport you want to spend some $ on. Use that bike to ride around and see what our trails are like, just don't spend money repairing it. Look on here and Craigslist for a good deal on a few year old high end bike for a fraction of the cost.
