We bought two for our kids. After 30 minutes of use the chain on one popped off. It was a pain to get back on then after 1 minute popped off again and continued popping off. We figured we got a lemon and decided to exchange it. The next day the second bike's chain popped off and we repeated the same process as the day before. After reading reviews of this bike on other sites it seems this is an extremely common problem with no solution from Razor.

As other reviews mentioned, the chain fell off within the first 5 days. We pulled off the front panel and were able to fix it. Its definitely sized for an 8 or 9:year old. My 10 year old can ride it but its slow going uphill, and his legs are pretty close to being too long.

We also have the pedal version. Both are fun, but we prefer this electric version - no pedaling. We've been riding it in our house, taking turns among my son, daughter, and wife. Very, very easy to assemble. Only issue is it says to charge this thing for 12 hours before the first use and charge it for 12 hours after every use. Not sure why it needs to be charged that long after the first charge. There is a battery charge indicator turning red to green telling you when it's charged. Definitely recommend this. Walmart has the best price on this thing too.

I live in the desert ours works fine, lasts 30 minutes. All of the bad reviews are in cold weather. Batteries don't do well in super cold temperatures EVEN TESLA BATTERIES. Pretty common knowledge. He ha shad it three years works the same it did since day one.

We have had for a week and love it. It_-Ès easy for my 7 year old to ride and I feel safe with him on it. Easy assembly and holds good charge so far.

They are 6 and 5 and have no problem riding it. A little timid at first but once they caught on its non stop!!

My daughter has friends with this but other kids have always run the battery down before she can get on, so I got her one and she's been having a blast countersteering drifts and doing 360s.

My grandson loved the power rider but after about an hour, the chain came off. We took it apart and fixed the chain, but it came off again in just a few minutes. I decided this would be an ongoing problem, so returned it.
