    • Sturdy and well made.
Color: XD-Black
This was a Christmas gift for my 12-year-old grandson who wanted a fat-tire bike. He and his dad put it together very easily, took maybe 15 minutes. We live in Minnesota, so there hasn’t been a lot of chance to ride yet because it’s winter, but he did try it out and rode it easily. He’s tall for his age, so it fit him. A bike path runs next to their home, so I’m sure he’ll get lots of use with it. Since it hasn’t been ridden that much, I can’t know if it’s going to hold up very well, but does look very sturdy and well made. I purchased because of reviews. I’m sure he’ll get many years of use from the bike. ... show more

I can't say I've ever used the bike, but it's sturdy as all get up and looks great on my deck trying to remind me to use it. One day ...one day.

    • Bent rear frame and axle
Color: XD-Black
I ordered 2 bikes. One was good, the other has a bent rear frame and axle so shifter does not align properly. Bike shop said too much money to try fixing. Not worth putting money into new bike.

This was pretty easy to assemble. I’ve taken it out a few times and it feels like good quality for how cheap the price is.
