  • Description

    The GSD is designed to carry two kids, a week’s worth of groceries, or 400 lbs. of cargo, but it’s only 71" 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 4' 11" to 6' 5" —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


    Zeit Online

    “The Vektron is an ideal choice for urban commuters, whose way to work includes a longer cycle route or train journey.”


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