Questions riders ask
- Where can I get my Tern fixed?
- 11 network shops list Tern among the brands they work on. Many shops work on other brands too, so call and give them your model.
- Where do I find the manual for my Tern?
- Tern posts manuals and support on its own site. We link to it on this page.
- Is it worth repairing, or should I replace it?
- Most problems, like flats, brakes, a loose plug or a worn chain, cost far less to fix than a new bike. Our repair-or-replace guide walks through when a repair makes sense, and a shop can give you a quote before any work.
