These aren’t bikes cluelessly designed by people whose main job is designing sleeping bags. Sonder bikes are designed by real riders.

Sonder’s Frontier is responsive but stiffer and less damped-feeling than some all-day adventure rivals
NX Eagle drivetrain shifts smoothly and cranks feel solid
Decent value
Handling doesn’t feel fully engaged on ‘proper’ MTB trails
Slightly undamped ride quality
