Tern unveils the GSD—a Bosch ebike that fits the whole family, but carries a family too

Taipei, Taiwan, August 2nd 2017 – Urban transportation specialist Tern Bicycles unveiled the GSD — an ebike that defines a new category: ‘compact utility’. 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—shorter than a Dutch city bike. With Tern’s best-in-class folding technology, it packs down small enough to fit in a VW Touran or an urban apartment. It adjusts to fit riders from 150 – 195 cm—so mom, dad and the kids can all use it. A Bosch Performance motor, with up to two batteries, powers the GSD for up to 250km. It comes fully equipped with integrated lighting, rack, mudguards, double kickstand, two XL panniers, and even retractable passenger foot pegs – everything needed to shift to a bike-centric lifestyle.

“Most of the ebikes on the market today basically look like standard bicycles with motors and batteries grafted on,” said Josh Hon, Tern Team Captain. "That means that all of the valid compromises that were made in designing a muscle-powered vehicle are carried over to the ebike, where they don’t make as much sense. The Tern GSD is the result a fundamental insight: when you design a bicycle around an electric drivetrain, you don’t need to compromise key functionalities like comfort and cargo capacity to optimize for speed. With a Bosch drivetrain, 20” wheel bikes ride just as fast as 700c bikes but thanks to smaller wheels, deliver punchier acceleration. The smaller wheels also allow us to maximize cargo capacity. And with top speed removed from the optimization equation, we were free to design the GSD with a comfortable Dutch-bike riding position. Best of all, we were able to fit all this goodness into a package that’s only the size of a standard city bike.”

“One of our guiding insights was that cargo bikes are most useful in city centers, but they’re correspondingly difficult to manage and store,” according to Galen Crout, Communications Manager at Tern. “Dense urban centers bring cargo bikes to life—where groceries, schools and work are all within a bikeable distance—but they’re also where houses are small, and where bike theft is a persistent problem. We’re creating the compact utility ebike category to let people in cities enjoy the benefits of cargo bikes without the limitations.”

Fits the Family
The GSD is an ebike that everybody in the family can ride. Tern’s patented adjustable stem, special cockpit geometry, and super low step frame make the bike easy to handle and ride, even for very small riders. Taller riders will appreciate the expanding cockpit and handlebars that can be adjusted for height and reach. Heavier riders will appreciate the massively buttressed frame and fork, and components that are designed to handle loads of up to 180kg.

Super Stable
Just as a scooter is easier to ride than a motorcycle, the GSD rides and handles better than many ebikes on the market today. The GSD’s smaller wheels, low frame, and centrally mounted motor and batteries give the bike an extremely low center of gravity. Coupled with an extended wheelbase, the GSD is remarkably stable and easy to handle. This extra stability is critically important and appreciated when the GSD is fully loaded with cargo, especially with the wriggling child variety. And since ebikes are typically ridden at higher average speeds, this extra stability adds to safety.

Capacious Capacity
The GSD is built to carry stuff, lots of it. The frame, fork, and components have been tested to exceed 180kg of total weight for the rider and cargo. The GSD comes standard with an 80cm integrated rear rack and side panniers with a total capacity of 62L. The GSD fits two children in Thule Maxi child seats or one adult passenger. Additional carrying capacity can be added with lower deck supports, a rear tray, and a front tray. Tern will open source the frame attachment point dimensions so riders with an interest can also design and build their own custom cargo accessories.

Portabilty, Storability
Despite its extra large cargo capacity, the GSD packs small to fit into tight urban environments. Since the GSD is no longer than a standard bike, it will work with standard bike racks on cars and buses. But even better, patented Tern folding technology lets the GSD pack even smaller – three seconds is all it takes to reduce its height by 1/3rd and its width by 40% so the GSD can fit INSIDE mid-sized cars like a VW Touran. With two GSD’s packed in the back of the car, family bike adventures will never be the same again. The GSD is even designed to fit into small elevators with a specially designed rack that allows it to stand vertically.

Component Quality
Whereas many cargo-oriented bicycles use mostly standard bicycle parts, the GSD goes a step further with some of the most robust parts available. Examples include Magura 4 piston disc brakes, custom 2.4" Schwalbe Super Moto-X tires, Boost thru-axle hubs, and custom 36mm width double-joined rims.

The GSD, designed as the ultimate car replacement or small business utility vehicle, launches together with a collection of accessories, including Eurocrate-standardized front and rear racks, a passenger kit with KLICKfix adapters, and optional foot supports. The rear rack, sized for up to four Ortliebs, is designed for optimal compatibility with up to two Thule Yepp Maxi Seats. The base price of 3,999 EUR (3,999 USD) includes a pair of 62 L Cargo Hold panniers, a Bosch Performance mid-drive, and a 400 watt hour Bosch battery.

“It’s a bike that fits a family, but it’s also a bike that the whole family can share” said Hon. “When you’re investing $4,000 in a new electric bike, fundamental versatility makes a world of difference. Fit any riders, passengers, or cargo, and fit anywhere.”

Tern will debut the GSD at the Fall trade shows, starting with Eurobike 2017. Dealers and consumers can stop by the Tern booth at B4-405, or the Tern demo booth at DA-417 to test ride the GSD.

GSD = get stuff done.
Really great design. I was impressed that they spec'd boost thru axle and dual piston brakes.

The pricing is much better than Yuba spicy Bosch or Edgerunner or Benno.

This will be great seller for Tern. I know several shops are looking forward to getting these bikes.

Kudos to the Tern team!
I rode one of these from the place I was staying to the InterBike show in Las Vegas last September... a distance of about three miles. The bike was somewhat heavily loaded, and I was riding with several members of the Tern team. The bike was a delight; my first experience with an e-bike or a cargo ("cargo-capable") bike. The mid-drive motor was smooth and quiet, and I could really feel it kicking in when I dialed the boost up. The ride was smooth and the bike felt well-balanced in spite of all the gear I was carrying. It's also a real eye-catcher. I'm not planning to buy one yet, but I can see how it would be a great replacement for a second car! Steve

There is so much tubing on that back half. Looks like you could park a truck on it!
It's a very sturdy frame. Lots of carrying capacity, and there are a number of bags, racks, platforms and such to optimize it. It stands up on its back pegs for storage, transport on an elevator or other limited-footprint application. The only thing it doesn't do is fold, so it wouldn't work as a commuter bike for me. A lot of local errands could be done with it though!

I guess my comment was leaning towards too much tubing. That frame looks way stronger than the wheel and spokes, but they do keep little riders legs out of the wheel! So far my feelings about cargo bikes leans towards the security of it while I'm shopping. When a bike looks that good, it can disappear in minutes. Come out of the store with my purchases and the bike is gone! I'd definitely have Veloinsurance on it. In over a year, I've net let either of my Haibikes out of my site, except for quick bathroom stops.

Yes, I have that concern as well. My commuter bike is a folder, so I never leave it unattended... it goes inside with me wherever I go. Likewise, I never leave my road bike unattended. I don't generally carry a lock. The GSD would have to be left outside. I would worry about it. I also would worry about vandalism. I'm probably a bit overly paranoid.
One thing I liked about the GSD (and all the Tern electrics I saw) is that the batteries require a key to remove, so at least there's less chance of the battery getting "boosted". :)
Wondering if any of our e-bike dealers on this forum have any insider info on the delivery dates of the first GSDs? I have mine on order through my dealer and Tern had said end of April for initial stock (which is now). I'm not ready to bug my dealer yet and thought first I would check here to see if any of our helpful dealers on this forum have heard any updates or have received any inventory.
