Enormously useful, surprisingly small. Despite its mad hauling power, the Tern GSD S00 electric bike is the same length as a regular e-bike and it packs down to fit into even smaller spaces.

  • Features

    • Perfect for many places a standard e-bike doesn't fit—elevators, trains, apartments—this bike packs down to 1/3 its volume in only 10 sec.
    • The GSD is designed to carry 2 kids, a week's worth of groceries or 400 lbs. of cargo
    • Includes Cargo Hold panniers and a frame-integrated rack
    • Andros stem offers handlebar height and reach adjustments
    • Adjusts to fit riders from 4 ft. 8 in. to 6 ft. 4 in., so mom, dad and the kids can all share it
    • Fits 2 Thule Yepp Maxi child seats or 1 Thule Yepp Nexxt Maxi seat with no adapters needed (child seats not included)

    Imported.

    Free Adjustment Period:
