Is there a reset button on a razor sweat pea pocket mod

Find out whether it is 6 volts or 12 volts and there should be two wires that feed the motor either cut or splice and attach another set of wires with fuse in the line (simular to jumper cables) raise the back tire so it does not touch the ground and place jump wires to the negative and positive of the battery.
If the motor moves in either direction without blowing the fuse the motor is good if not then its bad. Uses the same amperage fuse

replace the fuse with a bulb of the same voltage rating
like 12v bulb
it will take the spikes but it might allow her to over load it too an motor git warm then the thermalfuse might kick in .
worn out motors an batteries do this stuff

cant figure out how to open storage compartment on kiki

Maybe your big battery inside the pocket mod is dead. That happened to my daughters, but then we took it to a shop

there isn't one, but there are fuses by the battery that can be replaced

there is an on/off switch right below the seat next to where you plug in the charger, then you have to twist the right hand grip

none

Signs of the Razor Bistro battery needs replacing.

I've included two wiring diagrams. Hopefully one of them is what you're looking for:
