The GSD fits a wide range of riders, from 150 to 200 cm (4'11" - 6'7") tall and weighing up to 130 kg (287 lb).

Many GSD accessories are waterproof (like the Cargo Hold 52 Panniers) for all-weather riding, and you can also add a bike canopy to help your passengers stay dry & comfortable. When winter hits, switch to studded tires and the GSD is ready for snow and ice.
