The Tern GSD S10 is a serious folding electric bike. Despite everything it can haul, the GSD S10 is actually the same length as a regular bike, so it fits anywhere a standard bike can. The Tern GSD is designed to carry two kids, a week’s worth of groceries, or 180 kg of cargo.
With Tern’s best-in-class folding technology, it packs down small enough to fit in a car or an apartment. Plus, it adjusts to fit riders from 150 – 195 cm – so mom, dad and the kids can all share it. Despite its city-bike footprint, the GSD boasts cargo-bike capacity, with a maximum gross vehicle weight of 200 kg (440 lb). The GSD folding electric bike uses a Bosch motor and battery.
