FRP 2 Stroke Pocket Bike 03, Pocket Bike for Kids W/ Strong Dual Brake, Realistic Racing Pocket Rocket Max Speed 20 Mph, Mini Bike Max Weight 165 LB-Ultra Edition, White

this bike is perfect size and so adorable for my 5 year old bike loving boy and I was so excited to give it to him for Christmas. when it arrived it was easy to assemble and didn't take very long but then when we went to add gas it had a warning on the tank with a ratio of oil to gas, which was surprising considering I ordered what I thought was a 4-stroke mini bike. turns out it's a two-stroke and they did issue a small refund but like I told them I wouldn't have ordered it if I would have known it was a two-stroke and my reasoning was valid because we have had nothing but issues out of both two stroke bikes that we bought since they opened them on Christmas morning. The bikes keep turning off they're smoking a lot even though we are using the measuring bottles that were supplied with the bikes to measure the oil and gas ratio. and my middle son had his brakes fail on his and wrecked it the second day due to brake issues. there has been bolts coming out Non-Stop some with threads that were messed up and others that were put together before it was boxed up and apparently not put together correctly or anything tightened up. on my youngest son's his keeps turning off after only riding for 15 to 20 minutes I'm guessing due to overheating then we had one that had a pinhole in one of the fuel lines so we had to replace that. It's been 3 days, and while these were definitely a showstopper on looks the maintenance just isn't practical with young kids who want to ride more than have their bike broke down needing more maintenance. my bf has been non stop working on one or the other. My oldest got a four stroke and hasn't had 1 single issue. I definitely regret not sending it back and accepting the tiny refund they offered bc now I will be dealing with this at least for the next year before I can even think about getting them different bikes.
