It is a bike that will likely tick many boxes for anyone planning multi-day rides, without first returning home for their tea.
This cracking value and rock solid machine from Sonder is just crying out to be loaded up and taken to the horizon.
Giving several centimeters of squish, their suspension-like characteristics help the Frontier float over rough terrain. With big handlebars, an upright position, and loads of stand-over, the Frontier is great for roistering about on, and could certainly serve as a regular mountain bike.
The Frontier might be considered a Jack of all trades but the clever bit is, it's able to master most of them.
