The Hidden Canyon 20” is basically built for that mix of fun and “I want to ride where my parents are riding” energy you get down in places like the Forest of Dean. Light enough for kids to actually enjoy the climbs up the fire roads, and with disc brakes so they’re not getting sketchy when it turns damp and rooty (which… it will).

The suspension fork is more about making it feel like a proper mini MTB when they’re bouncing along the blue or green trails rather than pure performance, but kids usually just think it’s brilliant anyway.

If you’re rolling around Dean Forest Cycle with it, it’s the kind of bike that lets them feel like they’re really “on the trails” instead of just tagging along—while you end up doing the classic parent move of chasing them down the singletrack with a half proud, half panicked grin.
