Trek Marlin+ 8 hardtail eMTB mixes business with pleasure [Review]

Jun 2024 · Jeff Barber

The Trek Marlin+ 8 electric hardtail mountain bike is singletrack-worthy and a fun commuter bike too.

Highs
  • Comfortable commuter and fun bike for light-duty trail riding

  • Capable, MTB-worthy parts spec

  • Modern look and feel

Lows
  • Entry-level fork isn’t very responsive

  • Battery isn’t easily removable

  • Tires are fast rolling but aren’t ideal for cornering or running lower pressures
