Tern GSD S10 Cargo E-Bike

Enormously Useful. Surprisingly Small.

The GSD is designed to carry two kids, a week’s worth of groceries, or 180 kg of cargo, but it’s only 180 cm long—the same length as a standard bike. With Tern’s best-in-class folding technology, it packs down small enough to fit in a VW Touran or an urban apartment. Plus, it adjusts to fit riders from 150 – 195 cm—so mom, dad and the kids can all share it.
