Tern Launches Upgraded GSD Compact Utility eBike

June 2018 — Urban transportation specialist Tern announced the launch of a second GSD model equipped with the most sought-after features, including a Bosch Performance Line CX motor, an Enviolo cargo hub, and a 500 Wh or 1000 Wh battery configuration.


A distinct new ebike form factor, the original GSD was introduced for model year 2018 to strong reviews. The GSD is a bike designed to help cyclists do more—carry their kids to school, do shopping, and get to work faster. It can also be used for commercial purposes, such as delivery or rental.

"The reaction to the GSD has been overwhelmingly positive," said Josh Hon, Tern Team Captain, "but we still got a wish list for changes from our dealers and customers. We're always listening, so here's model #2 with the most requested changes."

The changes include:

Bosch Performance Line CX

The GSD S00 features the best drivetrain available with just a bit more torque for really heavy loads. It also delivers more powerful walk assistance, so riders can easily maneuver the GSD on steep slopes.

Bosch 500/1000 Wh configurations

With Bosch's exclusive dual-battery technology, riders can choose either a standard 500 Wh or an upgraded 1000 Wh configuration—with the latter providing a range of up to 200 km. Every GSD comes with dual-battery wiring, so riders who choose the standard 500 Wh configuration can upgrade to 1000 Wh at any time by adding a battery.

Enviolo Cargo Groupset

Enviolo's heavy-duty hub is THE hub for high torque electric cargo applications. An infinitely variable transmission with a gear range of 380% lets riders easily change gears under load and at standstill, delivering a smoother ride in stop-and go city traffic. A Boost thru-axle and beefed-up internals deliver improved service life, even in demanding commercial applications.

Abus wheel lock

An integrated Abus wheel lock uses the same key as the battery locks and is perfect for when the rider has to leave the GSD for a short time to make a delivery or run into a store. A heavy-duty Abus chain can be added for additional security.

The GSD S00 will be on display at Eurobike 2018. Tern’s booth, located in hall B4-405, will be open for visitors from July 8 to July 10. Visitors are also invited to test-ride the GSD at demo area DA-411. The standard one-battery configuration of the GSD S00 will retail for €4895/$4995 and will be available in stores in Q1 2019.
