Not wanting this to turn into a fight of any description, but I bought my PL Comp brand new about 6 years ago - still have it and as yet (he says with fingers crossed) nothing has failed - the bearings are like new, they tyres are just about getting to the point where they need replacing due to lack of tread and there is a very slight bend in the rear axle where its carried my 13st a$$ for those 6 years. I don't jump with it but I regularly go between 20-30mph and occasionally to 35+ This is in local fields and on the beach. All I have ever really done to maintain it is make sure I hose it down thoroughly after beach use to get rid of sand and salt. I'm considering getting an XR seat as they are supposed to be light years better, but that will be the first mod in the 6 years other than fitting a speedo. I'm sure there are problems with them, a friends Flexi bug does look stronger and for SY to have had so many failures means there must have been issues with his, but all I can say is for me it has served me well for general cruising and messing around.
