Hola, are you tired of buying and replacing the speed sensor or the cable of your ebike? In my case it was the second time it got broken and I decided to replace it for something much cheaper. A magnetic switch (less than 10 $) that works exactly the same as the original one which is very expensive. In this video
you can see the procedure. The references of the original replacements: 245MYAMH-02V (40 $ for a cable 700 mm with a magnetic switch in one end! Crazy!
LG650 X94-81670-20 (20 $) for a piece of cable 650 mm long

Hope this helps !!!!!!
