The new 2020 TreeFrog Pro 3 carrier has a double layer deck, which could carry 3 bikes (total loading capacity is 60kg) or maximum 2 e-bikes. The Pro 3 double layer Polycarbonate deck has 5 TreeFrog vacuum cups, each rated to hold 110kg, 3 fork mounts and 3 robust ladder strap rear wheel holders. The 9-15x100mm universal fork mounts securely hold either 3 standard 9mm quick releases or 15x100mm forks (with our Boost spacer works with 15x110mm mountain-bikes), no need to switch out fork mounts! Pro series are available with different 12mm, 15mm and 20mm thru axle fork mount sizes (including one for the Lefty fork) with no extra charge. It’s a great choice for families, for all cars, and can be mounted on the roof.
