I bought my son a pocket bike via ebay years ago and it is alot of work for a parent that at the time I didnt realize so thought I would put this review up to help you.. One you find one on ebay make sure you know the price since many company will sell them real cheap but the norm is 100-200 dollars to ship it,,, the total price for one should be around 250 but no more...make sure you buy one that is at least 49 cc but no less,,lesser ones have to work to hard to get the motion it needs with the weight of the child and it will burn the clutch and engine out to soon...the expected life of one of these is about 5 years if it is taken care of and the bolts tightened after 5 uses,,the vibrations work them loose....also you have to get a helmet and saftey gear you deem nessasary and them little bikes can reach the speed of 35 miles an hour so if your child is under 10 then I would recommend another type of toy,, also dont let the kid ride un supivised so expect hearing can we go pocket biking alot,, my son buggs me alot about it,, we lost our muffler and got another on ebay for 20.00 and it only lasted 5 trips before if fell apart,,its like owning A CAR where the only place that stocks parts for it is internet,,,,, well anyways it is alot of fun but can be dangerous and a hassle but for me and my son its worth it,,,,good luck and happy bidding and safe riding
