Available with supplier
- Usually built & dispatched in 5-6 working daysThe Perfect Birthday Upgrade! We bought the Marin Bobcat Trail 3 for our son’s birthday, and it has been an absolute home run. Performance: The geometry is perfect—it’s stable enough to give him confidence on the trails but agile enough to be a blast to ride. Build Quality: You can tell Marin didn’t skimp on the essentials. The frame is solid, and the components (especially the hydraulic disc brakes) are a huge step up from typical entry-level bikes. Style: It looks sharp! He’s already received a ton of compliments on the sleek design. It’s the ideal bike for a growing rider who wants to move from neighborhood paths to real dirt trails. Seeing the massive grin on his face after his first ride was worth every penny. Highly recommended!
