SUNDERWELL 40cc Mini Dirt Bike, 4-Stroke Gas Bike with Front Fork, Shock Absorber and Soft Seat Cushion, Max Load 165Lbs, Pull Start Cooperate Disc Brakes and Up to 19mph (Green)

My 10-year-old nailed it on the first try! So stable and fun. The look on his face was priceless! Best surprise ever. He's on it every day after school. Total success.

When I purchased this bike it clearly said 50cc in the description. I received a 39cc bike and I notice the description changed. If I hadn’t already put it together and started it, I would return it. The engine doesn’t run that great and I’m very disappointed in the false advertising. I would have bought a different bike. I see others have also had this problem.

Great starter bike. My son loves it. 10 year old. Only thing is packing can be more durable please. Came in with a broken front fender due to delivery issues.

Would not recommend. It was very difficult to put together as the brake pads didn't fit and we had to manually adjust it. The chain has been problematic. Just constant maintenance and cheaply produced. I hoped to get a year out of this for my son, and we've had plenty of issues just 6 months in.

Great starter bike for my 7 year old grandson. Seems well made for a Chinese product. The seat is not soft but ok for a kid. Love the disc breaks on front and rear. Also love that all the hot areas around the engine are covered with plastic. Shipping was fast for me. The first one I ordered, different bike and supplier, didn't tell me until I asked a week later that they did not have it in stock. gave me 5 days left to find another. Glad it happened as this one is a 4 stroke, less carb issues in my opinion than the 2 strokes, and this one came in 3 days after ordered. Very impressed and saved my grandsons Christmas! One issue I had on assembly was the front caliper bolt was on so tight, I had to use vise grips to loosen it so that I could install the second bolt because it was bending my Craftsman allen wrench. It comes with one bolt installed and the caliper tilted up for shipping. So far it starts pretty easy however every once in awhile the puller doesn't engage the engine. Not sure if this is going to be problem in the future or not. But for me I push the priming bulb 4 times, close the choke and it starts on the first or second pull. So far very happy with it.

Great dirt bike but items were missing in the box such as bolts and nuts which meant I had to run to home depot christmas eve to buy what was missing so my son wasnt disappointed.

My grandson loves his little dirt bike and never gets off of it!

I gave this motorcycle to my grandson for Christmas. He was just able to get it out today for the first time and the pull cord broke three times. I am not happy. Do not buy this product I am not happy. Do not buy this product
