Start up throttle mod?

[averhamdave]

I have a Chinese generic 36v rear hub drive, silver fish battery powered bike come into my possession.

It had no battery so I've fitted a spare 48v battery that I had.

All runs well, surprisingly good bike.
There's a 2 position selector switch on the left side. "Start off" or "Pedal"
There's a throttle on the right side which on "Start Off" applies a little power to get the bike going. You then switch to "pedal" and it operates normally from the crank sensor.
Now my issue is that with it using a 48v battery off it flies, way too fast.

My question is, is it likely I can modify the controller to give full available power to the throttle such that at lower speeds, say 10/12mph the bike can run on the throttle only?

Ebike throttle on bikes tend not to be controllable, one can try a twist grip type but think the controller firmware/programming doesn't support such control with most.

I'm dealing with a simple controller here. I dont see the throttle itself having much effect. I'm pretty sure there'll be a mod that can be made to the board to achieve what I'm trying to do.

I think some of the older bikes do allow throttle 'all the time' but you still need to have some pedal movement. I find mine invaluable. Esp like today when I'm low in energy and anemic but needed to get out.

Mines a Freego.. Atman in Kent that does a lot of parts for Freego might be able to advise.

That's the case with some but many don't need pedal movement. I put a throttle on someone's otherwise "pedelec only" Falcon Ebike some time ago (the plug was sat there ready for it in the controller box) and that powers off from standstill. Most of the Chinese ebike kits are the same.

This bike powers off from standstill with throttle (again as so many other models do), I'm asking if the circuitry can be modified to enable full power use of the throttle?
