Merida eOne-Forty 8000 2020 review

May 2020

Merida's eOne-Forty 8000 is a well-made and decently priced e-MTB that offers a sorted Shimano drive system nestled sleekly in a carbon chassis. It rides and handles well, but most riders would probably be just as well off with it's bigger brother in the form of the eOne-Sixty, which is much more capable, scarcely heavier and just as good value. Big Read: Racing e-bikes at the EX Enduro; how much difference does a motor make?

Merida eONE-FORTY 9000 review

Apr 2020 · Luke Marshall

The eONE-FORTY is a trail-friendly and capable ebike that prefers the smooth to the rough

Highs
  • The geometry puts you in a comfortable position for extended pedalling

  • Even with its ebike weight you can still be relatively nimble on the trails

Lows
  • The suspension travel will hold you back when the terrain gets rowdier

  • Its looks and the Thermo Gate have divided team opinion

Merida eOne-Forty 9000: first ride review - MBR

Jan 2020 · Jamie Darlow

The new Merida eOne-Forty 9000 is the little brother in Merida’s new range of e-bikes with their battery hidden away inside the down tube.

Highs
  • Fun and exciting ride, easy to play with on the trail, proven Shimano motor, and boasting loads of smart features.

Lows
  • Too flexy when trails get faster and firmer, geometry is needlessly conservative. Too pricey.
