  • Best bike ever!!!
Color: Gray 21 Speed Size: 29 inch
I rode this bike almost all summer and yes in the trails too! Sometimes I stop to see if everything is still good and yes it’s strong and takes a beating in the rocks and rough terrain. I had wanted to take videos but maybe next summer. I will also change the handle bar. Customer service is fast and very reliable. They helped through the assembly process and even replaced a whole front tire without any issues. ... show more

  • Great Performance! Sturdy and Durable!
Color: Gray 9 Speed Size: 29 inch
If you’re looking for a reliable and versatile mountain bike, this 29-inch model is a fantastic option, offering a great balance of performance, durability, and comfort. The bike features a lightweight yet sturdy aluminum frame, which is ideal for both climbing steep trails and cruising over rocky terrain. The 29-inch wheels offer excellent stability, allowing for smoother rides over obstacles like roots and rocks. The larger wheel size also improves traction on loose surfaces and helps maintain speed, making this bike well-suited for both novice riders and experienced mountain bikers. ... show more

  • WOW
I purchased for my tall grandson and he loves it. It looks amazing and so expensive. I'm so happy I could get him something so nice. I had someone else put it together.

  • Great Value
Color: Gray 21 Speed Size: 29 inch
This is an excellent bike for the money. It rides smooth, has a good looking frame, and the 29” wheels and tires are great. The shifters and mechanical disc brakes are not high-end (as expected) but totally work well. A few downsides: The assembly “instructions” are kind of a joke - you are better off looking at a few YouTube videos. The front tire was mounted backwards (directional tread) easily fixable. The brakes and derailers needed a fair amount of adjustment/tweaking but it wasn’t too tricky. Really the biggest issue is that 1st gear (and maybe 2nd gear) aren’t usable - the chain rubs the rear tire. These are very low gears - you likely won’t ever need them but it still is a bit strange to have an unusable gear. Overall I’m very impressed with the value of this bike and would definitely recommend to anyone on a budget and is ok doing a few bike adjustments. ... show more

  • incredible value!
Color: Gray 9 Speed Size: 29 inch
This 29" mountain bike is an incredible value. The bike has a great paint job, and is easy to assemble. The bike needs the handlebars , seat, pedals and reflectors assembled. These steps are all easy for do-it youself people. I had no issues during assembly, and the brakes and shifters were adjusted at the factory, and needed no further adjustment. I highly reccomend this bike , the tires are excellent and the bike is a great value. If you need help with assembly, there is many youtube videos to help. ... show more

  • Worst bike I’ve ever rode
Color: Gray 9 Speed Size: 29 inch
Though it was easy to assemble, its build quality is awful. The seat is very uncomfortable and rigid while being angled upward. The petals become loose after only a few petals, even after an extreme tightening of the bolts. Additionally the instructions that came with the bike were for some children’s bike. The bike served me well for maybe 2.5 rides ... show more
