The lock and ride idea would be nice so it could be removed but no I would not make it so that is securing the kids. Bolt it in for sure don't take any chances. As to a helmet well neither of my kids wear them in the RZR. The weight of a helmet I feel is more likely to injure their necks than the risk of an accident. I'm pretty cautious with the kids in it we just cruise. No high speeds and no big jumps. If I take out my oldest (7yr old) to play a bit she goes with a helmet and or full gear. But most of the time it's just nice to go out as a family.

If you want to run a helmet you might use a hockey helmet with a full plastic face. Or I did look at a really small helmet that was pretty lightweight. But then again I did not buy it. People have different opinions on the helmet issue. I feel safe with the .095 DOM wall cage that surrounds them.
