The Good: Rides smooth. Easy to do tricks that involve spinning such as truck drivers. Tires have good grip. Grips that come on the hike are comfortable.
The Bad: Bike is heavy(to me. It weighs 24.7 pounds) so I recommend you take off the breaks and pegs. The only parts I think on this bike should be replaced are the stem, rims, (rims aren't too strong when it comes to roof drops etc) and I'd recommend changing the pedals to twisted pcs.
My overall review of this bike is that it's a very good complete bike. Few parts could be changed to make it a better Nike overall, however is definitely not needed. This bike makes tricks very learn able however I've came across one trick that's hard to learn on every other bike I've ride except this bike. When you tailwhip this bike it's just comes around perfect. So again overall this bike is great
