eONE-FORTY 400
Merida
Trail
eONE-FORTY 400 is an alloy electric trail mountain bike (2024), by Merida, part of the Eone family. This model is best for riders who want a more active, performance-leaning off-road feel, with a sporty, active riding position, with a surface profile that is well suited to natural trails and mixed off-road terrain. Metric-wise, it stands out for strong value-for-money versus many similar bikes, good fit flexibility for dialing in rider position, and capable suspension support for rougher terrain. The trade-off to keep in mind is a firmer ride feel than comfort-first options and battery range that is better for shorter daily use than long all-day outings.
