July 14, 2026 - Launched back in 2011, Tern Bicycles has become an industry leader producing premium quality bikes that are highly functional.
The company’s recent release of their GSD S10 Gen 3 is a great example of innovation and what an electric cargo bike can be. As the transportation landscape continues to evolve, it’s ready to replace your car, or a second vehicle.
Simply put, the Tern GSD S10 is an efficient, and emission-free way of hauling cargo, whether that’s equipment, groceries, your significant other, your kids, and even your dog.
While the 6061 aluminum frame is not the lightest on the market, its construction is designed to not only get the job done, but it’s also made to last, and is backed by Tern’s 10-year frame warranty. In addition, it’s third-party tested to meet German cargo bike standard DIN 79010 for superior safety and reliability.
Durability does not end with the frame as the Tern GSD S10 is complimented with an array of quality parts. Shimano’s Deore 10-speed drivetrain provides accurate reliable shifting while the Magura MT-C ABS 4 piston brakes are set to manage the heaviest of loads.
Tern’s custom Suntour front suspension fork helps manage and smooth out the ride under load and absorb large bumps or potholes. Add 20-inch Schwalbe Pick-Up tires and a Cane Creek suspension seat post and get ready for a reliable and comfortable ride.
Powered by a Bosch Cargo line motor with 400% assist and 85 Nm of torque, the Tern GSD S10 is definitely up for the task, whatever it may be.
A Bosch Powerpack 545 Wh battery, that can be upgraded to 800 Wh, is neatly tucked behind the seat tube and offers 98 km of range. There are also frame mounts to house an additional battery for extended excursions of up to 196 km of range.
The powerful Bosch Cargo line motor is managed via the Bosch Smart System utilizing an LED Remote controller and an easy-to-read Kiox 300 colour display.
The bar-mounted controller is very intuitive and allows easy management of the four power-assist levels. The Kiox 300 delivers all the important ride data, along with theft protection, ride customization, and navigation tools. Plus, the entire system is UL2849 certified, the gold standard safety certification for electric bicycles.
Thanks to features on the Bosch Smart System like walk assist and hill assist, manually moving the bike, or starting on a hill, especially under load, makes life much easier. With the addition of the Bosch Anti-Lock Braking System, quick, seamlessly smooth braking is at your fingertips.
The Tern GSD S10 comes equipped with an extremely bright 700 lumen Ignis front headlight offering high/low beam options, all operated by bar-mounted push buttons. The RearStop brake light is always on while riding adding an extra level of safety.
Built to handle a gross vehicle weight of 210kg (463 pounds), the Atlas G rear rack has a 100 kg (220-pound) capacity, and our test model came with a pair of waterproof Cargo Hold 72 panniers.
These massive rolltop bags have a 72-litre capacity which saw me stuffing them to the max for my rides. I appreciated the easy use of the magnetic Fidlock buckles which allowed easy access to the panniers, even with full fingered gloves on.
Our test bike also came with a front Hauler Rack that offers 20kg of capacity to secure a variety of loads, along with mounting holes on the base to bolt on a crate, or even secure a small pet carrier.
The upright and balanced rider position allows you to confidently move through traffic, handle tight corners and navigate congested areas under load.
Out on the road the GSD 10 is at home in an urban environment. The e-cargo bike’s wide wheel base and lower centre of gravity makes it a fun and surprisingly nimble performer despite its hefty weight of 82lbs.
The powerful Cargo Line motor gets the bike up to speed quickly and provided consistent power for an extremely stable ride, even under a heavy load.
I was super impressed with how smooth the Tern felt on the road. The combination of the Suntour front suspension fork, and the Cane Creek suspension seatpost really did their job well.
Plus, the wide profile aluminum fenders kept me clean from water and road grime on those rainy ride days.
Even without those features on our test model, a pillow on the rear rack did the trick on the Tern for dinner out on the town with my wife – an added treat was not having to valet park it.
I love the fact that these bikes not only can carry large loads of cargo, but also an adult passenger like my wife or adult children. With the addition of their Clubhouse seat pad and Sidekick footpegs, you’re ready to leave the car at home again.
Rest assured that the easy-to-use Atlas Lockstand Gen 2 dual leg kickstand will provide solid support when parked, and it comes with remote unlock, patented technology. Unless you know how to unlock it, you will not be able to wheel away the bike.
The GSD S10 has additional built-in security devices that help to deter thieves. The Abus front wheel lock is a quick, easy way to secure the bike for short term parking while the Smart System theft protection adds additional peace of mind.
Other features include the Tern Andros adjustable stem which makes front end adjustments a breeze, while the adjustable seat post takes care of the back end. The one frame size accommodates riders from 4’11” to 6’ 7”.
The Andros adjustable stem allows you to fold the handle bars making the Tern GSD S10 even more at home in urban environments as it also has the ability to be parked vertically which is an added bonus for apartment dwellers. You can easily tip the cargo bike up on its rear rack to fit it into elevators and then tuck it away in a corner. The foldable handlebars also help when transporting the bike in the back of a minivan.
The Tern GSD S10 sets an admirable benchmark for e-cargo bikes as a strong, reliable, and versatile transportation option – the fun factor is a bonus.
