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.


Highlights Of This Electric Bike

Uses the Bosch eBike System

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 4'9''– 6'4'' — so mom, dad and the kids can all share it.

Carries the Family

With room for up to two Thule Yepp Maxi child seats, plus grocery space to spare, the GSD lets you ditch the minivan. The low step-thru frame makes getting on and off much safer, and with an extra low center of gravity, the GSD is stable and steady.

Carry More

The GSD boasts cargo-bike capacity, despite its city-bike footprint—up to 400 lbs. including rider. Build it up with Cargo Hold Panniers and the Shortbed and Transporteur racks, to carry industrial strength Eurocrates, a week of groceries or a family picnic plus the kitchen sink.

Boosted Components

We use burly and dependable, cutting edge mountain bike technology to make the GSD superlatively strong. Magura 4 piston disc brakes, custom 62 mm Schwalbe Super Moto-X tires, Boost thru-axle hubs, and custom 36 mm wide double-joined rims, provide the rock-solid foundation for a bike spec’d to carry 180 kg.


Deciphering This Electric Bike

Sometimes the language used to describe electric bikes can be confusing. Let us walk you through it:
Tern: This is the brand of the electric bike.
GSD: This is the line of bikes. It stands for "Get Stuff Done."
S00: This is the model of bike. It is the more-equipped model of this line.
1000wh: This refers to the capacity of the battery used in this bike, in watt-hours. The battery is a Bosch dual-battery system (1000 Wh) for a range of up to 200 km.
