I'm looking to get a good basic hybrid treking bike for general fitness and family bike rides. I don't want to spend too much as I'm a beginner and if I (we as a family) take to the biking hobby I will upgrade if need be in a year or 2! I've been looking at the Dawes Sahara & Barracuda h700 online but don't know if they are any good? Also saw the Carrera Parva in Halfords, but don't hear good things about Halford's? Any advice greatly appreciated.
