2025 Tern

GSD S10

The Tern GSD S10 Gen 3 is the result of nearly a decade of refinement since the original GSD essentially created the compact cargo e-bike category back in 2017. With a beefy 463 lb max capacity that's been DIN 79010 certified, the GSD can haul serious weight while the hydroformed frame, longer wheelbase, and lower center of gravity keep it stable and confident even when you're maxed out on kids and groceries.

Bosch's complete ecosystem is what separates this from the pack, combining that punchy 85Nm Cargo Line motor with legit ABS braking borrowed from motorcycles to prevent wheel lockup when you need to stop fast. Add in the Smart System with GPS tracking, electronic locking, theft alarms, customizable motor tuning through the app, and dual battery capability that pushes range beyond 140 miles in Eco mode, and you've got a genuinely connected riding experience.

The little details add up in ways that show Tern actually listens to people who ride these bikes daily, from the remote-release kickstand that lets you mount safely with cargo to the oversized seatpost levers redesigned because the smaller ones hurt people's hands. With the adjustable stem offering 110 degrees of rotation, tool-free cockpit adjustments, and a fit range from 4'11" to 6'7", this is one of the rare cargo bikes the whole family can genuinely share without compromise.

Tern stands behind the GSD S10 with a 10-year warranty and promises 7-year parts availability, which is a big deal when you're dropping eight grand on what's essentially a car replacement. Throw in an accessory ecosystem covering everything from dual kid seats to rain canopies to trailer hitches, and you've got a bike that's actually designed to eliminate your need for a second vehicle rather than just being a fun weekend toy.

Frame stiffness & handling: The unique frame design is impressively rigid, even when fully loaded. It delivers stable, predictable handling whether you’re carrying cargo, passengers, or riding solo.

Outstanding security features: Between its café lock, GPS tracking, motion alarm, and motor/battery lockout through the Bosch Flow app, the GSD sets a new bar for built-in bike security. You’ll even get phone notifications if someone tampers with it.

Top-tier safety systems: The GSD includes anti-lock brakes (ABS), UL 2849 certification for its electrical system, and DIN-tested frame safety. It’s one of the most safety-forward cargo bikes on the market.

Huge payload capacity: With up to 463 lbs of total carrying capacity and a 220-lb rear rack rating, this bike means business. It’s as practical as it is powerful.

Terrific motor performance: The Bosch Cargo Line motor delivers smooth, intuitive power and serious torque. It’s less a wild stallion and more an ox. It’s steady, strong, and always ready to work.

Great value for the money: Sure, the GSD isn’t cheap, but given its premium components, smart design, and Tern’s proprietary tech, the value proposition holds up. You’re paying for true refinement and longevity.

High-quality accessories: Every rack, bag, and passenger add-on feels purpose-built. Thick, durable materials and thoughtful details make the entire ecosystem feel cohesive and premium.

Price and weight: The GSD’s cost and heft will limit its audience, but for those who can manage both, it’s about as close to “downside-free” as any e-bike gets.
