    • Whip it good
It's a great bike and ride smooth stops on a dime the only thing is I have to replace the seat because I wanted more comfortable seat

    • ZERO quality checks from manufacturer prior to shipping!
I bought two OUTROAD bikes. The first bike rear axle cracked within 2 months of on-road use (commuter bike) and the cost to replace it was more expensive than the bike itself. I liked the bike overall, so I bought another identical OUTROAD and this one came out of the box with a warped rear rim... 3/8 inch variance from center -- it's crazy how they sent this to me in this condition. I'm not going to buy another one.... I loved the bike handling, performance and price. But this is crazy! ... show more

    • High quality Adult Teen Sport-Mountainbike (defintely not suitable for Big&talls)
Hmm, - this bike performs well, but the only caveat is it is not a perfect fit for "adult"- I'd say, shoe size 8 to 9, tops. Otherwise, it is basically "top of the line", fairly affordable given it is designed to "outclass" other mountain-sports bikes in the same price range; it has that potential, to outperform other sporty mountain type bikes. Ultimately, I'd say this is actually a 25 inch (in theory, in practice it is designed as a 25 inch wheel bike, but I've run into small but avoidable issues, and I've only a size 10 shoe. So, if Adult is meant to include the 10-12 range, then NO). Also, i can't get the "foldable" part of the bike to function, and it isn't very light (maybe I haven't tried hard enough, I mean it says it can fold, like in case it needs to be loaded into a car?). ... show more

    • nice bicycle
nice overall design and build quality. the instruction booklet tells you how to assenble the bike, but not how to fold it. you will figure that out. decided to replace the steel supplied seat post with an aluminum one, and plan to cut off the side mounted kickstand with an angle grinder, to reduce weight. the weight of bike is not excessive. the front brake caliper needed a slight adjustment with supplied allen wrench to align with front disc brake caliper. have ordered a hollow rear brake axle to make the rear wheel quick release, like the front one is. overall, a nice bicycle and i am making a few small improvements. ... show more

    • Bad tires
Review Image by Brenda Trinidad
The tires came with out air. Witch is fine ok but I've taken it 3 times to out air and it keeps getting a flat after a hour of just putting air in. Great bike but the tires are really not good.

    • Satisfied with the purchase!
Great bike and easy to assemble! It looks like the image and I am overall happy with the purchase. Make sure you tighten everything as it can be a little squeaky if not.
