Has anyone had experience with these new 50cc pocket bikes? I'm wanting to buy one for my 6 year old (we have some land so it's not for the road). I'm sure he'll be able to ride it OK but what about the engines. The one I looked at was a 0 four stroke. Simple enough and looks easy on maintenance. I'm sure all that pretty bodywork will get bashed around over time but I'm mainly concerned whether the no-name engine will go the distance and whether parts are available. Can you recomend a brand they all look the same.
