What is the difference between the Veloped 12er and the 14er?

The difference between the Veloped models is that they have different textiles.

Easy explained is this:

Sport= Our basic model. Fully working veloped with large basket and seat.

Tour: Tour model has a 2" deeper (not wider) seat, and it has insertions built into the seat cover, making it firmer and more comfortable to sit on;

it also comes with a rain cover for the seat and the basket included in the price

Trek: Is like the sport, but have one bag that you can attach to the seat with push buttons and one backpack that fits great in the basket.

Other than the textile difference they are Performance-wise the same.
