Rated 5 out of 5 by from All around best 24 bike out there! After much research, I decided to get this for my nine year old. Its only downfall is the saddle, you can't adjust its angle. This isn't a big deal because a new post is easily replaceable. It's super light, rock solid, and performs great. I have an aggressor pro, and we definitely get style points with matching bikes as well lol. Save time and just get this for your young ripper!

Rated 5 out of 5 by from Everything we were looking for After research of every brand of bike, we found the stomper! 1x drivetrain, flick shifters, beefy tires, dual disc brakes, super light aluminum and just the right components. My son was too big for most 20” and two small for other frames. The stomper fit the 10 year old perfect. And it’s way lighter than his 20” bike. So stocked on this bike for him!! The staff at the store was super helpful , great Bday present!

Rated 5 out of 5 by from Best Value in kids MTB We just got this Stomper Ace for my 8yr old son. He had trouble with grip shifters on his previous bike and I wanted something with trigger shift, 1x 8, disc brakes, and light weight. This bike checks all of those boxes and it’s about $200 less than other bikes that are similar! My son loves his bike and he’s already feeling pretty comfortable on the trails with it. Great bike and the people at Dick’s set it up for us tuning the rear derailleur and adjusting the brakes before we took it home. Great bike, great service!!

Rated 4 out of 5 by from Great bike for my 9 year old!!! I bought this bike for my oversized 9 year old for his Bday. He loves the bike and it fits him great. The price was great at the store untill I bought the 2 year extended warranty and after 2 days of riding it I had to take it to a bike shop to tune it up. The assemblers at Dicks only put it together, they don’t do any gear adjustments or anything like that. Maybe it’s normal to buy a 300 dollar bike then go a spend another 90 to get it working properly???
