If you’ve been in our Gateshead shop lately, you might have noticed one bike family taking centre stage – the Trek Marlin. We see a lot of first-time riders and parents looking for that long-lasting “big kids bike,” you know…the one that’ll do them from the age of 12 until they’re married. The Trek Marlin is also unbeatable on value for money, the Marlin has been our top-selling range for months… and for good reason.
The Marlin isn’t just popular – it’s loved by the masses. The feedback from new riders tell us it’s , comfy, easy to ride, and “class for jumps.” It’s that hardtail mountain bike that doesn’t overcomplicate things, but still gives you that exciting, “ready for anything” feel.e
With prices starting at just £525, the Marlin delivers quality without emptying your wallet – and that’s a big part of why it’s become the go-to bike here at Team Cycles.
Perfect for Growing Riders – Big Kids Included
Parents often ask us about the transition from kids’ bikes to adult frames. Here’s our favourite trick – the Marlin in sizes XS or S is often a better fit for taller kids than a Large or XL kids-specific bike.
Why?
- More room to grow: An XS or S Marlin gives your child extra years before they size out.
- Easier handling: Despite being an “adult” bike, smaller frame sizes are still comfortable and manageable for younger riders.
- Better long-term value: Instead of outgrowing a kids’ bike in a season or two, a Marlin can stay with them for years.
We’ve seen plenty of young riders jump straight onto an XS Marlin and take to it instantly – no awkward riding position, no wasted money, just miles of fun.
