Where can I get my DYU fixed?

Search the partner network by ZIP and call ahead with your model. Many shops that work on e-bikes take brands they don't list.

Where do I find the manual for my DYU?

DYU posts manuals and support on its own site. We link to it on this page.

Why does a rear flat cost more on a hub-motor DYU?

The rear wheel holds the motor, so the tech has to unplug the motor cable and handle a heavier wheel to change the tube. Many shops price it separately for that reason.

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.
