Picked up a dirt cheap E-Bike on Craigslist.....Display/Controller question

[98 SNAKE EATER]

A week after receiving my first E-Bike (Sondors Fold X), I spotted this one on Craigslist and jumped on it

The seller said it was bought new in June, but had issues with the power cutting in and out randomly.

He took it to a bike shop and they said it needed a new motor

Totem sent him a complete rear wheel/motor assembly, but it still had the same problem after installing.

Frustrated, he bought a few new bikes for his family and listed this one on CL

Turned out to be an easy fix (bent battery tabs)

Anyways, we've been enjoying it, but I'm curious if there's a way to unlock the speed limiter of 15mph?

I've seen it done on other controllers, but couldn't find any info one this one:

Tried pushing "+" and "-" together and a 4 digit code setting came up, but I have no idea what it's for.

It's asking for the pass code number.

OK, found the code on an Amazon review and was able to change wheel sizes and do some freewheel test spins.

I can defnitely see a difference, but of course the speedo is off, so I'll have to do GPS and SOTP tests tomorrow

There's no option to change top speed?

There's no option to change top speed?

From what I can see, only the wheel size and voltage can be changed (gives me the option of 24, 36 or 48)

please report back and let us know if changing the wheel size helped top speed! btw that thing looks super clean+the free motor!! good snag!
