I have an Ice and it is such a nice riding bike. It's just brilliant for everything. It sits on the backwheel so good and is great for sidehops. I'm not entirely sure how strong they are. I've only had mine a week! Haha. The tubing on it does look quite thick though so I hope it lasts long. They are quite light too and the frame is very stiff, the built in booster works great. Definately recommended. Hope this helps. Hunter
