Exactly what youd expect from a 40cc bike made in China

This compact bike has proven to be excellent for our needs. The only drawback I've encountered is the tendency of the handlebars to shift, but I've effectively addressed this by using brackets and serrated bolts. Now, they remain securely in place. The bike boasts impressive fuel efficiency, running for extended periods on minimal gas, with sufficient power to tackle hills. Thus far, it's been a positive experience. However, one notable issue is the sharpness of the plastic on the left handlebar, which has caused deep cuts to my kids' hands. I highly recommend using sandpaper to smooth any overhanging edges for added safety. Despite this, overall, the bike has been fantastic, and I almost wish I could take it for a spin myself.


The appearance is pleasing, and the fit and finish are of high quality. Assembly is easy.

My boys adore these mini bikes. They want to ride them every day.


I purchased this for my 6-year-old daughter, and it arrived with a governor set at a safe level for her to learn. As she grew older, I adjusted the carburetor to provide more power. Despite weighing 210 lbs, after tuning the carb, the bike easily takes me up small hills at around 12 mph. Keep in mind that it lacks suspension, so it may bounce on rough trails when ridden by little ones. However, it's perfect for yard use. I haven't had to replace any parts, and a simple adjustment addressed the chain stretching caused by my weight. Overall, we love this bike.


Purchased this for my grandkids and preferred its design over the 2-stroke one my wife bought for them. It starts on the first pull; just remember to pump the primer on the bottom of the carburetor. My grandkids love it. I appreciate the fact that it's a 4-stroke, much quieter than the 2-stroke, and appears to be more dependable. The 2-stroke one my wife bought had to have the carburetor changed twice, and it's only a month older than this one. I waited to write this review to ensure its dependability.
