They're fairly rugged... they have a removable "seat" section. When you take it off, it can be clamped on a table top. both brakes are independent pots, there is the accelerator of course, 12 buttons, a high hat (!) and you can switch between GP and Cross mode, which changes the steering from tilting the handle bars instead of turning them. It feel rugged enough, and for $15-$20, I think it was worth it. I could take pictures and post them, if anyone is interested.
For the price, even as a novelty for Paperboy and Enduro, its worth it.
Let me know if you have any other questions
