Great Bike!

My son loves the bike. He is 10 years old. The bike will grow with him and should be good for him for many years.

We got my extra tall son that just turned 9yrs old this bike for his birthday. He moved up to the 26in from a 24 inch. He maneuvers it easily on single track dirt trails and its light enough to ride around the neighborhood as well. We are avid mtn bikers and love this bike!

Great Experience

After searching for a specific bike for a few days, I came across it at RSP after discovering that most other places had sold out of it. The RSP rep I emailed with was really helpful in answering my questions about assembly and shipping. The bike was a little more expensive than I’d seen it at other places, but it would’ve come unassembled from them and then I’d have to pay a local shop to put it all together, which meant it would’ve actually been more expensive. When the bike came in, it was assembled and inspected and in great shape (literally only had to re-mount the front wheel and check the tire pressure). Could not be more pleased with the experience. My son loves the bike and is already asking to go on longer and longer rides. Thanks for everything.
