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 car. The low step-thru frame makes getting on and off much safer, and with an extra low centre of gravity, the GSD is stable and steady.

Enormously useful. Surprisingly small.

The TERN GSD S10 is designed to carry two kids, a week’s worth of groceries, or a load 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 Mum, Dad and the kids can all share it.

TERN GSD Annimation

A Utility Bike Designed to Fit Your Life.

Despite everything it can haul, the GSD is actually the same length as a regular bike, so it fits anywhere a standard bike can. But there are lots of places a standard bike doesn’t fit. That’s why we designed it to pack down to 1/3rd its volume in only 10 seconds. That means you can store your utility bike in your urban apartment, fit it in the elevator, or stash it in a train for weekend getaways.

Same size as a normal bike

Fits the Whole Family Too

Cars don’t come in S, M, L & XL to fit the driver, so why do bicycles? The GSD is designed to be shared by a family. It adjusts to fit Mum, Dad or the kids—any rider from 150 – 195 cm. Best of all, thanks to Tern’s adjustable stem, and compact geometry, adjusting the bike only takes seconds.

Fits the whole family.

Bosch Motor and Battery

Riding with kids on the back, uphill? No problem. There’s a reason Bosch is the global leader in e-bike systems—and it’s not just their outstanding performance. We work with Bosch because they offer the best service network, remarkable testing, and next-level quality control.

Ride All Day

The GSD is one of the few bikes equipped with Bosch’s latest Dual-Battery technology. You can connect up to two batteries for a range of over 150 miles. Tour from dusk to dawn, or commute for weeks on a single charge.

Safety First (Second and Third)

Cycling is safer when you move at the speed of city traffic. Fast acceleration is a given with a Bosch Performance motor combined with smaller wheels. We’ve developed custom, virtually flat-proof, Schwalbe tires to give sure-footed stability on even the nastiest roads. Add super-bright LED lights, reflective decals, and a see-and-be-seen riding position, and you have a bike optimized for safety.

Elevator Friendly

Cargo bikes are most useful in cities (high density of things to see, do and move), but they’re also harder to manage and store (small apartments and bike theft). Most people don’t have space for a cargo bike. We designed the GSD to fit small elevators, so you can keep it indoors. We even designed the rack to let the bike stand vertically, for compact and stable storage.

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.

See-and-Be-Seen Geometry

The GSD features a relaxed geometry that puts the rider in an upright, comfortable position. Swept back handlebars and ergonomic grips take a lot of stress off the neck, shoulders, and wrists. You’re also able to see (and be seen) over the tops of most cars, which is a great benefit in traffic. With Bosch power, comfort and performance can coexist.
