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.

The Same Length as a Standard Bike


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.


Fits the Whole Family Too

Minivans 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 mom, 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.

Carry More

Despite its city-bike footprint, the GSD boasts cargo-bike capacity, with a maximum gross vehicle weight of 200 kg (440 lb). 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.

Enormously Useful. Surprisingly Small.

The GSD 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 mom, dad and the kids can all share it.

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.


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.

Cargo Hold Panniers

Think of the Cargo Hold panniers as a trunk for your bike. Keep your lock, rain jacket, and tool kit inside so they’re always ready. And then load them up with a week’s worth of groceries, or a tent, balance bike, cooler and toys for a weekend trip to the park. Use the lid when it’s raining or roll it up and out of the way when you’ve got extra large stuff to carry.

Yepp, It'll Fit Two

Thule Maxi child seats are the best in the business. The GSD is designed to fit two, with plenty of foot clearance for the rider. No special adapters needed.

Note: The GSD fits two Thule Yepp Maxi seats, or one Thule Yepp Nexxt Maxi seat.

All Day Battery

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 250km. Tour from dusk to dawn, or commute for weeks on a single charge.

Sell the RV

The GSD is an awesome touring machine. It’s got room for six Ortlieb bags (4 on the rear rack and 2 on the front), and a range of up to 150 miles. A bit of careful packing lets you bring a full touring load, together with a little passenger. That means two GSDs let a family of four tour the world, no bike trailer required.



Cargo Hold™ Panniers

The Bike-Trunk

Think of the Cargo Hold Panniers as a trunk for your bike. Keep your lock, rain jacket, and tool kit inside so they’re always ready. And then load them up with a week’s worth of groceries or a tent and balance bike for a weekend trip to the park. Use the lid when it’s raining or roll it up and out of the way when you’ve got extra large stuff to carry.

  •         Flat-pack design for a neat and tidy look, loaded and unloaded

  •         Water-resistant for all-season carrying

  •         Reflective lettering for nighttime visibility

  •         Fits up to 68 L (30 kg/66 lb per pair)

Shortbed™ Tray

For Every Cargo Contingency

The Shortbed Tray is a heavy-duty cargo upgrade for the GSD that carries serious loads low to the ground. It fits standard 600 × 400 mm Eurocrates, so you can carry up to 80 liters of provisions. Pack it with a cooler and save the day at soccer practice, or leave it in its original configuration for IKEA runs. Depending on your cargo preference, mount it parallel or perpendicular. Offers easy access for swapping and removing one or two batteries.   

  •         Heavy-duty rear cargo carrier, designed to transport up to 35 kg (77 lb)

  •         Built to fit standard 600 × 400 mm Eurocrates, coolers and the weekend IKEA haul

  •         Mounts perpendicular or parallel, depending on your load and preference

  •         Includes two Tern SideStrap bungees

  •         Compatible with vertical-standing storage

Transporteur™ Rack

Front and Center

The Transporteur Rack is a modular cargo carrier. Accessorize it with a 300 × 400 mm Eurocrate, a standard crate of 20 beers, or a recycled wooden box. It carries up to 20 kg, so even when you’re carrying two kids on the back, you can bring a picnic too. With two convenient bottle mounts, you can load it out with water for a long tour, or a handy bike lock for commuting in the city.

  •         Robust front cargo carrier, designed to transport up to 20 kg ( 44 lb)

  •         Installs on Tern’s robust Combo Mount, for serious hauling

  •         Mounts on the frame (instead of the fork) for unencumbered handling, even under heavy loads

  •         Built to fit standard 300 × 400 mm Eurocrates, beer crates and a range of third party accessories including pet carriers and coolers

  •         Includes two rear-facing bottle cage mounts, so you can load up on water or attach a convenient folding lock


Carry The Kids, Carry The Groceries

The Tern Clubhouse turns your GSD into a modular minivan. Configure it with the included seat pad and backrest to carry two kids. Swap out the seat pad for a 600 mm x 400 Eurocrate and haul a week’s worth of groceries, or bring a (very) little one along in a Thule Yepp Maxi seat. With specialized tubing that protect small hands, and a compact profile for vertical storage, the Clubhouse lets the whole team ride together.    

  • Designed to fit two kids, from 5 – 10 years old*

  •     Converts in seconds to a heavy-duty grocery-hauler, built for 600 × 400 mm Eurocrate compatibility

  •     Includes bar tape for added rail-padding

  •     Includes seat-cushion and kid-designed reclining backrest

Sidekick™ Lower Deck

Low Rider

The Sidekick Lower Deck adds a pair of lower shelves to the GSD. It works as a convenient foot-rest for passenger, and extra storage space for cargo.

  •         Designed to support up to 50 kg (110 lb) combined

  •         Hauls low to the ground for superlative handling and stability

Sidekick™ Seat Pad

… On A Bicycle Built For Two

The GSD lets you bring one adult passenger along for the ride. The Sidekick Seat Pad lets that passenger ride in comfort. With a KLICKfix rack mount, the Sidekick Seat Pad clips on and off in seconds. Pair it with the rest of the Sidekick kit for extra comfort and convenience.

  •         Adds a comfortable rack-top cushion to the GSD

  •         Attaches with a KLICKfix Rackpack mount, for installation and removal in seconds

Sidekick™ Foot Pegs

  •         Specially designed for the Tern GSD

  •         Helps a rear passenger ride in comfort and style

  •         Pops out of the frame with a simple push

  •         Tucks back into the frame just as easily

Sidekick™ Bars

Spartan™ Rack

A low-riding front rack

The Spartan Rack is built from large-gauge tubular aluminum for strength and stiffness and features a very low-center-of-gravity for excellent stability when loaded with panniers. The adjustable mounting system allows the rack to be fitted to both Tern 20” and 24” bicycles. NOT COMPATIBLE WITH TARSUS FORK.   

  •         Carries hefty pannier bags on the front of your bike with excellent stability

  •         Fits most small- to medium-size side panniers

  •         Sturdy construction and low center of gravity

  •         Stainless steel mounting hardware

  •         Not compatible with Tarsus fork on some late model Verge and Eclipse bikes

Batten™ Straps

An Essential for Hauling Cargo

Forget about calling a U-haul and use the Batten Straps to secure any and all cargo to the GSD. Daisy-chained together or individually, the two 3-meter long straps quickly fasten just about any odd-shaped bulky item. Whether you’re tying down a push bike or carting around extra luggage, the Batten Straps are an essential tool for the GSD.
