The Good: Lightweight and very strong, will take alot of punishment and deal with it no problem. Grippy wide tyres makes speed riding through dirty tracks and slippery surfaces easy. Fantastic brakes mean you have complete control downhill.
The Bad: The crank and pedals are of a poor quality so i would reccomend getting those replaced. quick release mechanism on front and back tyres are a theives dream so i would have those removed.
