Who is the Tern HSD S00 best for?

The S00 is the right model if you want the best-equipped HSD and expect to use it regularly.

It suits riders who want one bike for school runs, commuting, shopping, weekend journeys and shared household use. It is also the strongest option if you want the HSD to feel as smooth and low-maintenance as possible — particularly in stop-start city riding.

Choose the S00 if you want the premium HSD setup: Enviolo Heavy Duty hub gearing, Gates belt drive, Bosch Smart System equipment and the smoothest, most refined HSD configuration. It is not the model every rider needs, but it is the model for customers who want the easiest HSD experience from the start.

Enviolo hub and belt drive

The S00’s biggest difference is its drivetrain.

The Enviolo Heavy Duty hub gives smooth, stepless shifting that suits city riding, loaded riding and shared household use. Unlike a derailleur or a fixed-step hub, Enviolo lets you simply adjust resistance to suit the ride rather than selecting specific gears. The Gates belt drive keeps the system cleaner and lower-maintenance than any chain-driven setup.

Bosch Smart System and everyday usability

The S00 also gets a more refined Bosch package, with Smart System equipment designed to make the bike easier to live with day to day: smart connectivity, easier ride information, dependable motor support and a setup that feels calm and controlled in everyday use.
