01
Origin
The Matts J is Merida's kids mountain bike line, designed around the principle that children's bikes should be properly engineered rather than cheapened. The standout feature is the Tektro hydraulic disc brake system — a component specification that gives children safe, modulated stopping power even with smaller hands that struggle to generate cable-pull force. The SR Suntour fork is tuned for lighter riders, and the Shimano drivetrain provides reliable gear changes for developing riders.

The verdict
+Strengths
- Hydraulic disc brakes provide genuine stopping power manageable by children's smaller hands
- SR Suntour fork tuned for light riders actually absorbs bumps — unlike adult-spec forks on budget kids bikes
- Shimano drivetrain shifts reliably even with the rough handling kids give their bikes
−Weaknesses
- Heavier than balance/run bikes or single-speed kids bikes — first-time young riders may find it heavy
- Hydraulic disc brakes require occasional professional bleeding — more maintenance than mechanical
- Limited wheel size options (20" and 24") — riders may outgrow each size within a couple of years
