Merida One-Forty 6000 review

Dec 2022

On paper Merida’s brand-new One-Forty platform looks rather mental but, in reality, it’s a very different animal than its geo chart suggests. It offers a unique-but-welcoming and practical ride that balances predictability with all-out fun. Its build kit has been wisely picked considering its asking price, too; making it one of the best trail mountain bikes you can buy.

Merida One-Forty 800 first ride review

Jun 2018 · Guy Kesteven

The new Merida One-Forty 800 is chunky on the scales as a complete package and okay rather than outstanding value on paper.

Highs
  • Outstandingly connected yet still playful ride quality, superb suspension and tyres, one of the best mid-travel bikes we’ve ridden

Lows
  • Relatively heavy, you can get a similar spec for less cash

Merida One-Forty 800 First Impressions

Jan 2018

Merida One-Forty: the right tool. When you want to carve up a turkey, you don’t use a spoon. And when you want to rip a trail, you don’t want some flim-flammy noodle cycle. You want a bike with purpose and guts. Maybe it’s just the colour which gives it the appearance of a piece of …

Highs
  • Sturdy, tough feeling construction.

  • Great value build kit.

Lows
  • Rims aren't taped for tubeless out of the box.
