No Pedal Assist
- Thread starter jwaldrich

What happened between the time it worked, and the time it didn't? There is usually some event that causes a sudden failure like this, however insignificant it might seem at the time. Knowing what it was will help us help you find the fault and fix it.jwaldrich said:
Otherwise, I would recommend carefully examining all the wires and parts (sensor, bracket, magnet ring, etc) associated with the pedal assist sensors, since unlike the throttle, those would be likely to affect the pedal assist.
For instance, if the sensor has been moved too close to or too far from the magnets, it may prevent it from reading their passing and so provide no signal to tell the controller to do anything.

Which specific model is your bike? Looking at pics online, most of their models use a single piece PAS sensor, where the magnetic disc and the sensor are integrated into one unit, so unlikely there's an alignment issue. I'd suspect wiring/connections rather than the PAS sensor.
Did the issue start after transporting the bike in your Jeep?
Another question: Does the system power on and respond normally to it's inputs, *other* than having no pedal assist?

Here are some ideas:
I saw online that ViVI ebikes have LCD screens. Does it power up and show anything?
If so, could you take a picture?
There are 4 types of external sensors: Brakes, Throttle, Pedal Assist (Torgue), Speed/Gear.
If you break sensors show that you are breaking, then the motor won't engage.
Even if you have a functional throttle or pedal assist (PAS).
If your bike is using these, there is a reasonable chance taht rough handling can cause them to report false breaking.
Your display can show if you are breaking and disconnecting the sensors will also disable them.
Throttle can be configured to override Pedal Assist, however it might not be by default.
So unless it worked before, you might need to either change the configuration or get a working PAS.
Faulty PAS can only do one of two things: Send that you are not pedaling or that you are pedaling like a robot.
You should be affected only by the first: Controller can block throttle if no speed and no pedal strokes are detected.
Speed/Gear should not affect your scenario. Just mentioning it.
That is about as much I can help with blind.
