My mates got one, The bike will just stay on the back wheel for ages , i find it good for side hops but really hard for wheelswops . I wouldn't say they are weak frames as we have ridden it roughly. They look great but they are fairly expensive If there is anyone out there who wants one and they haven't ridden one yet i really suggest you have a go on someone Else's first because you just don't know if you will like it or not as its great for somethings but not really suitable for others.
