01

Origin

The eBig Nine debuted in 2017 as Merida's first e-hardtail XC mountain bike, applying the proven Big Nine chassis to an electric powertrain. Unlike the full-suspension eOne-Sixty, the eBig Nine targets riders who want the efficiency and low maintenance of a hardtail with the hill-flattening assistance of an e-MTB — making it popular for trail riders, regular commuters on rough routes, and fitness-oriented riders exploring forest trails.

The verdict

+Strengths
  • Shimano EP801 motor delivers responsive, natural-feeling power with class-leading 85 Nm torque
  • Hardtail simplicity: lower maintenance, lighter weight, and better power transfer on flat and rolling terrain
  • 630 Wh battery enables full-day trail riding without range anxiety on moderate terrain
Weaknesses
  • Hardtail limits rough descending capability compared to full-suspension e-MTBs — rear end transmits impacts directly
  • ~24 kg is heavy for a hardtail; analog hardtails do the same trails at under 12 kg
  • Entry builds use entry-level forks and drivetrains that don't match the motor's capability
