The Honda Racoon Racoon UB01 looks even more similar. I bet they've got an all-ebike-knowing supernerd chained up in the basement of that museum, but he may be barred from using a phone
An old brushed motor then, it is possible to run with no controller but doubt it as a controller will control the battery current.
My swizzbee is brushed but does use a controller.
Tbh your bike like my swizzbee is fit for a museum and retirement.
If your bike was based on a Honda Racoon, it'd be similarly specced at 220W, brushed motor etc.
