The standard mode must be switched very quickly and not to be reversed in case you are got by the cops while running a "little fast". I want a jumper that I can pull and hide in my trouser pocket so without the jumper the bike runs at 15mph and the motor is powered only if the pedals are spinning.
How does the controller recognize the spinning pedals? Do I need a sensor?
You'd need the pedalec sensor for the latter, if the controller has a separate pedalec input. Otherwise you'd need a pedal-based throttle.
For the former, you'd need a "jumper" that when installed turns *off* the limits, by a set of relays or similar. When the jumper is installed, the relays disconnect the pedalec loop and the speed limiter loop on the controller itself, if it has them.
If you do not want to disable the pedalec part and intend to pedal all the time anyway (recommended to keep people from noticing you as much ) then you only need a little plastic card like they use on treadmills, which would hold apart a little leaf switch or a roller on a microswitch (recommended for weatherproofing). That switch would go to the speed limiter jumper on the controller, enabling the limit when the card is pulled.
The card could be anything, including an ID card on a lanyard around your neck, or a piece of jewelry on a long necklace, that would pull out of the slot automatically as you dismount or even when you lean back far enough.
