Sonder Transmitter Carbon Review

Sonder Transmitter Carbon Review

By Talyn Williams

A tough bike ready to cut through the roughest terrains with ease. For those who refuse to compromise, this trailblazer is for you.

Blisteringly fast, sweetly detailed, radically dialled . a proper aggro attack bike that loves to shove its big front tyre into trouble and then bosses it out big style
