X-PRO Hawk Mini Dirt Bike, 40CC Gas Power 4-Stroke Dirt Bike, Pull Start, 10" Wheels! (Black, New Decals), DB-Z010

Amazing, I'm 210 pounds and it was fast with me on it. Bought it for my 9 year old so while it is fast, I would definitely say it's still at a safe speed for his age. I'm a 33 year old mom that has no business being trusted to put something like this together, but it was really easy, I only struggled with one part and I figured it out, so if I can, anyone can lol Very nice bike, its not super loud but loud enough that your kid won't be able to hear you unless you're yelling. It does well in the grass, it can be bumpy depending on your yard so I would make sure they're comfortable on cement or something smoother before they take off in the grass.

I wanted to wait a few weeks before I made this review. Ordered it for my son for his 9th birthday. It arrived 2 days early which was great, putting it together was simple. It goes fast enough to get home excited but not to fast to ride around our 1/4 acre back yard. Chain came loose the first few times he rode it but after some adjustment we’ve found the sweet spot for it. Takes exactly $1 to fill his gas take at current gas prices, we thought that was cool. Overall I’m very pleased, he has his own key, has to put gas in it, and soon we’ll do the first oil change. Overall I’m not expecting it to last forever, I can see the engine is basically a weed eater engine which can probably be easily swapped out if need be. The frame and suspension seems fairly robust. It has been in some minor crashes this far and has held up well.

Shipped and arrived fast, arrived early. I did run into a problem however their customer service was phenomenal. I needed to get a replacement part which I expected to take weeks, but they reviewed and processed my claim in days. I reported the issues Wednesday and was sent a tracking number for the part needed by Thursday. I will be ordering additional bikes from them! Thank you X-pro!

Perfect Purchase!! If this is your price range, buy the X-Pro !! Does about 25-27 mph. Runs a very long time on a tank of regular gas. 4 stroke so no messy oil/gas mixing. Quieter than a lawnmower. Runs cool all day. Assembly was super easy and quick. Less than 30 minutes and we put fuel in and was riding. Satisfied Customer!!

I bought this for my great granddaughter who is six. She absolutely loves riding it. She fell while riding ( she was fine) but the throttle broke. We tried contacting the manufacturer to get a replacement throttle but they would not answer our emails. We have since found one that will work.

I'm giving this product a five-star rating because it truly exceeded expectations. It is exactly as directed and works exceptionally well. The description was accurate, the setup was simple, and it's very easy to use. This product has been a lifesaver for our family, and the fast delivery was appreciated. Worth every penny. My 7 year old and 12 year old both got one. Perfect size.

The biggest issue that held me back from 5 stars was getting the chain alignment right. I know a lot of people have made the same complaint and moved on or gave up on it. I’m fairly mechanically inclined so it took some time. My 8 year old son ran it for the first time and the chain slipped off. After a some research and a few hours of wrench time, I got it locked in and has been riding it since with no issues. He’s put about 7 hours of run time on it with no chain slipping. He’s ridden through mud, dirt, grass and some road way with no complaints. Engine fires up first pull everytime. PRO tip, change the oil before you start it for the first time. The oil from the factory was a little low and I’m sure isn’t of any quality. Also, change the oil every ten hours per the manual. It’s super easy to do and only takes a little bit so a quart of oil should last you almost a year. My son has a blast riding it, it certainly rips for a 40cc. With any small engine, it takes attention and regular maintenance. Assembly took about 45 minutes and I did it solo.

A small adult under 200 lbs can ride it, but it won't be super fast at that weight. A small child 11 and younger will have fun. The only issue is that the plastic engine cover was broken, but it was here before Christmas, and that's all that matters. Thank you and Amazon for saving the day. We will see how it does once it warms up.
