Tern GSD S10 Gen 3 Electric Cargo Bike: The Ultimate Urban Hauler for Canadian Riders
Introducing the new completely redesigned Tern GSD S10 Gen 3 electric cargo bike—engineered for Canadian conditions and ready to revolutionize how you move through urban landscapes. With significant upgrades to frame strength, carrying capacity, and smart technology, the new GSD delivers unmatched versatility for families, businesses, and adventurers alike.
Enhanced Frame Design for Superior Performance
The Gen 3 model features larger diameter hydroformed tubing, creating a significantly stronger and stiffer frame that supports an impressive 463 lb maximum gross vehicle weight—a 23 lb increase from previous models. This robust construction accommodates riders from 4'11" to 6'7" and supports individual rider weights up to 287 lbs.
Premium Canadian-Ready Components
Equipped with the powerful Bosch Smart System Cargo Line Motor delivering 85Nm of torque and up to 400% assist, the GSD S10 easily handles Canadian terrain from steep city streets to challenging trails. The 545Wh Smart System lithium battery provides extended range, while the option to add a second battery makes long-distance travel effortless.
The advanced Bosch ebike ABS braking system prevents front wheel lockup on slippery Canadian roads and eliminates the risk of flipping during emergency stops—crucial for winter riding safety. Premium Schwalbe Pick-Up tires with double carcass construction offer exceptional puncture resistance and support up to 155kg per tire.
Intelligent Technology Integration
The removable Kiox 300 color display provides essential riding data, while the Bosch Connect Module offers GPS tracking, smartphone connectivity, and anti-theft protection—including movement alerts and electronic locking capabilities. Connect seamlessly via the Bosch Flow App to monitor battery status, plan routes, and customize your riding experience.
Thoughtful Canadian-Climate Design Features
The new integrated one-piece injection-molded rear wheel guard protects passengers and cargo from splash while improving safety. The conveniently placed top-tube charging port and 10-watt USB-C port keep devices powered throughout your journey. The upgraded Atlas lockstand supports 242 lbs with advanced silicon shields to prevent ice and mud buildup—essential for Canadian winter commuting.
Superior Comfort Systems
Enjoy unparalleled comfort with the premium Cane Creek Thudbuster suspension seatpost and Mobie 34 front suspension fork featuring larger diameter stanchions for improved stiffness and reliability. The tool-less Andros dual-arm adjustable stem allows riders to customize handlebar positioning for optimal comfort.
Safety Certification & Reliability
Unlike many competitors, every Tern GSD is UL 2849 safety certified with frames tested to rigorous DIN79010 standards, ensuring unmatched stability and durability. The replaceable rear rack (rated for 202 lb capacity) makes maintenance simple and cost-effective.
Available in three striking colors—School Bus Yellow, Beetle Blue, and Satin White—the 2025 Tern GSD S10 stands ready to transform your Canadian riding experience with its perfect blend of carrying capacity, safety features, and innovative technology.

How It Works
Frequently Asked Questions About The Tern GSD
Our customers often have similar questions, so we've compiled a list of the most frequent ones. If you need further assistance beyond these answers, our dedicated customer support team is always ready to help.
Is there an overall length difference between the GSD Gen 3 and the GSD Gen 2?
Yes, there is a difference in length between the two generations. The new GSD Gen 3, launched in spring 2025, has an overall length of 76 inches, while the previous GSD Gen 2 measured 73 inches. This slight increase in length enhances stability and cargo capacity without compromising the bike’s compact footprint.
What is the standover height of the new GSD Gen 3 vs. Gen 2?
The GSD Gen 3 has a standover height of 19 inches, while the GSD Gen 2 has a standover height of 20 inches. The lower standover height on the Gen 3 improves accessibility and makes it even easier for riders of all sizes to mount and dismount the bike comfortably.
What is the recommended rider height for the new GSD Gen 3 vs. the Gen 2?
The GSD Gen 3 is designed to fit riders from 150 cm to 200 cm tall (4'11" to 6'7"), while the GSD Gen 2 accommodates riders from 145 cm to 193 cm tall (4'9" to 6'4"). The expanded fit range on the Gen 3 makes it even more versatile for families, businesses, and shared use.
Can I add the USB-C charging port to any GSD electric bike?
No, the USB-C charging port is only available on the GSD Gen 3 models. This feature is integrated into the Bosch Smart System, which is exclusive to the Gen 3, and cannot be retrofitted to earlier GSD generations.
The rear rack on the GSD Gen 3 appears to be replaceable in case of damage. Is this true?
Yes, that's correct. One of the most requested upgrades, the rear rack on the GSD Gen 3 is now replaceable—a feature exclusive to the Gen 3 models. The rack is bolt-on, making it easy to replace if damaged, and it's built tough with a durable powder-coated finish. It’s also rated to carry up to 100 kg (220 lbs), making it ideal for commercial fleets, rental operations, or anyone who needs a heavy-duty, serviceable cargo solution.
Can I upgrade my Gen 2 GSD with the new fork used on the GSD Gen 3?
Technically, yes—but it's important to note that the new fork is specifically designed for the GSD Gen 3 R and S Class models, which come equipped with the Bosch eBike ABS braking system. While installation on a Gen 2 GSD may be possible, these forks are not currently sold as an aftermarket upgrade, and compatibility with non-ABS systems has not been validated. For safety and performance, we recommend using components designed specifically for your bike’s generation.
If I order a GSD bike from Scooteretti, how will it arrive? How hard is it to assemble?
Great question! At Scooteretti, we take pride in providing every customer with a hassle-free experience. Whether you choose in-store pickup or shipping, your GSD bike is first fully assembled, test-ridden, and fine-tuned by our expert technicians. Once it passes our strict quality control checks, we carefully repack the bike so that it arrives 95% assembled.
All that’s typically required on your end is to install the pedals and adjust the handlebar using basic tools—no special skills needed. And if you have any questions, you’re covered by our FREE VIP Platinum Support, giving you direct access to our eBike experts via email, phone, or video call.
It truly doesn’t get easier than that!
Can I use the same accessories on the tern GSD Gen 3 as the Gen 2?
Yes, most accessories designed for the GSD Gen 2 are fully compatible with the GSD Gen 3. This includes popular options like the Clubhouse, Sidekick footrests, Cargo Hold panniers, Storm Box, and more. Tern has maintained consistent mounting points and rack dimensions to ensure a seamless upgrade experience for riders moving from Gen 2 to Gen 3.
Is the Tern GSD Gen 3 UL certified for safety?
Yes, the Tern GSD Gen 3 is UL certified and built for maximum safety. It has passed rigorous stress testing by EFBE Prüftechnik GmbH, using forces scaled beyond normal conditions to meet the German DIN 79010 cargo bike safety standard, ensuring the frame and fork can reliably handle its 210 kg (463 lb) weight rating.
In addition, the entire Bosch® eBike system—including the motor, battery, and charger—is UL 2849 certified, the leading North American safety standard for electric bikes, ensuring protection against electrical fire risks.
