    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 ebike. 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.

    Electric Bike Review

    “The Tern GSD Review is a sturdy, reliable, non-flexy, compact electric cargo bike with plenty of accessories to transport kids or even other adults”

    Cycling Plus

    “An electric bike that really could replace your car...”


    “The Tern’s big selling point is that for all its cargo capacity and versatility, it’s actually no longer than a standard big-wheeled bike.”

    Electric Bike Report


    “We recently traded in our hybrid bikes for 2 Tern GSDs. (…) Having our GSDs has allowed us the ability to pack the necessary equipment and kids and travel on our own time schedule.”


    “... a compact utility e-bike that can haul it all.“
