e-fix – the small compact electric wheelchair

Turn your manual wheelchair into a compact electric wheelchair with the e-fix add-on drive. The drive can be individually programmed and can therefore be adapted perfectly to your personal needs. The electric add-on drive is the simple way to increase your freedom of movement. The e-fix also allows you to cover greater distances and handle slopes effortlessly.

Stay flexible - two wheelchairs in one!

E-fix flexibel 2-in-1If the situation requires it, the e-fix can also be easily moved by hand: You uncouple the drive wheels with a handle and your wheelchair can be pushed by hand as usual – either using the push rims or by an attendant. The manual wheels can usually still be used too.

Requires little space – simply take it with you everywhere you go.

The components of the lightweight and compact add-on drive can be quickly removed from the wheelchair without the need for tools. Everything is quickly and easily arranged. Even in the smallest of trunks.
