Still Small. Even More Useful.
With a 200 kg (440 lb) Maximum Gross Vehicle Weight, the GSD is ready to replace your car. It’ll let you carry two kids plus groceries, or a whole lot of cargo—but it’s the same length as a regular bike. Built-in dual-battery technology lets you ride all day, while space-saving features like FlatFold and Vertical Parking make the GSD incredibly easy to own and use.

BELLS & WHISTLES
One Size Fits Most
The GSD has an adjustable cockpit that resizes in seconds and without tools to fit riders 150 – 195 cm tall (4’11” – 6’5”), so you can easily share it with your family. The updated frame geometry with a slacker seat tube angle and higher handlebars also means the GSD doesn’t just fit—it’s more comfortable too.
Tern provides two different warranties based on the type of road the bicycle model was designed to be ridden on:
1. Graded and Maintained Gravel Roads (HSD, GSD)
This Tern bike is designed for individual personal use: riding with both wheels in contact with paved roads or graded and maintained gravel roads.
2. Paved Roads Only (All other Tern bicycles)
This Tern bike is designed for individual personal use: riding with both wheels in contact with paved roads only.
In addition, all Tern bikes are not intended for racing, jumps, hops, wheelies, or similar activities which may cause damage to the bicycle and risk injury or death to the rider.
The warranty information below refers to all Tern bicycles.
Tern bicycles are sold on behalf of our company (“Tern”) by selected Authorized Tern Dealers who understand the assembly and service needs of our products. Tern provides a warranty against defects in materials and workmanship to the original retail purchaser (“Owner”) of a Tern bicycle from the date of purchase according to the following terms:
Five Years: Frame, Handlepost, and Fork
One Year: All Tern or BioLogic branded parts and components, except as noted below.
Other: Any other parts or components are covered by the stated warranty of the original manufacturer of that part or component.
This warranty supersedes any other warranty supplied by Tern.
Extended 10-Year Warranty
Owners who sign up for Tern Care will be covered by an extended 10-year warranty for the Frame, Handlepost, and Fork, as long as they sign up within 30 days of purchase and are the original purchasers. In addition, the bike must have been assembled by an Authorized Tern Dealer at the time of purchase—regardless of whether the bike was purchased from a physical or online store.
The following items are excluded from the extended 10-year warranty:
Bikes for commercial use
All other parts not specifically listed (for example, but not limited to: Motorized Drive System)
The warranty does not mean that the Frame, Handlepost, and Fork are indestructible. All materials can fail if pushed beyond design and manufacturing limits. It simply means that these items are covered under the specific terms of this limited warranty.
