We bought this bike for a 13 year old boy who's over 150 lbs. My son is 5'2" and the seat height isnt too high for him. Im 5'9" and the seat height is just fine for me as well. Take your time in putting it together and read/look at instructions carefully. We live in a city and so have to haul the bike to trails or to our cabin to ride it. So it's not driven daily or even weekly. It's probably driven less then a month per year. We haven't driven it at high speeds. probably the highest speed we went is 30 mph. We bought the upgraded carbonater but when installed, the bike didn't work. So, we put the original carborator back on and it drives just fine. We drive it through narrow foot forest trails and dirt roads. It seems like a sturdy bike. For what we use it for and how often we use it, it's a great bike.

I got this bike a year ago and I recommend changing the carb, sprocket and the chain. I also recommend a CDI box. The delivery was fast and efficient, came with no damages. The assembly was easy, I do also recommend breaking in the engine with the oil provided than use whatever oil brand you’d like for replacement. I also want to note how I never got the email for the title, called the company up a year later and they even took care of everything! I dealt with amazing people in customer service and want to give Jenna a huge shout out for confirming all my information. I would definitely buy more products from this company, and will recommend it!

Do not buy these bikes. They look like they will be nice to ride but we rode ours for less than 2 hours and it broke down. Started falling apart. We couldn't ride since purchasing for my son at Christmas because of weather so we just took it out this weekend. It's obviously past return or any kind of reimbursement and the company isn't willing at all to make anything right because of that. Literally we have less than 2 hrs ride time on it and it no longer starts and when it was running it started falling apart and sounded awful within 2 hrs. Buyers beware!!! Do NOT purchase these bikes from thus company. They said they can only help us locate parts now to fix the bike that should NEVER be broken after 2 HRS!The company contacted me after I asked about a remedy for the bike. The lady tells me I need to learn about the bike and continues to try and school/scold me on what I need to learn. Very unprofessional. I told her I my son works with professional riders. I don't need to know about this bike. They rode with my son and the bike fell apart and no longer runs. Don't buy and don't deal with this rude company. My goodness this is ridiculous the way they email.

Have waited a while to write an accurate review. Bought this to ride with my son so that he could have it once he grows into it. The only issue so far is that the carb started leaking, which should be an easy fix when I get around to fixing it. Takes a couple of minutes to warm up but is definitely fun to ride. Have had no mechanical issues other than the carb previously mentioned. I assembled it fairly easy without any help. All tools came with it but I used my own.

Bike got shipped super fast only thing I found when assembling was one of the chain guard brackets was bent with a decent gouge in the plastic protector but all in all very satisfied with my purchase these bikes are better than what I expected for as cheap as they are for some reason in my Amazon app it was showing my shipment as possibly lost but I got this thing in 2 days but it was only one state over from me if your on the fence about getting one of these don't hesitate just do it!!!

I read many reviews on this bike and researched it alot. I will say I agree with what many have said. I also would start by saying if money is no problem and you have 2600 bucks go buy a name brand at a dealer. I thought alot about doing that but in the end decided that this was simply a toy and all I wanted was to ride around my property. The box arrived on time with no problems. If you are not at least mildly mechanical don't get this bike. Be patient things like the manual suck and obviously whoever wrote them didnt speak English. After assembly I went for my first ride. I quickly realized that the factory installed the throttle cable wrong and I had to redo that buy taking apart the carburetor and rerouting it. When I would turn right my throttle would go crazy. Also change out the garbage factory oil with quality 10w 40 motorcycle oil. About 5 to do that. As many said the factory carburetor was pretty bad. It would only run on half choke and didnt want to start well. Not that big of a deal. As many have said buy a 35 buck Mizuni carburetor upgrade and install that. I had almost no problems switching mine out. With the new carburetor upgrade the bike runs great, more power and idle problems gone. If you are patient and like to tinker you might like this project. The bike runs great and on performance and ride I would give it a 5, but I have to be honest and let people know you will have to work a little to get her running great. For 825 bucks delivered you cant beat it. Put it in the cart man! And buy yourself some fun you deserve iWanted to update. I have been riding all summer with this bike and no problems at all. Runs and rides strong.
