TLDR: I'm searching for an 18v controller for a small electrical balance bike which has a brushless sensored motor.
Wishes (from important to less):
- On/off switch
- Smooth throttle control
- Soft start / throttle curve adjustment
- Low/adjustable delay
- No/adjustable deadzone
- Determine min and/or speed
- 3 speed settings
- Power cut when brakes applied
Long story
Hi all (again),
I bought my 5y old son a Mondraker Grommy 16 (Google link) electric balance bike because I like driving my Zero FXE and wanted to give my son a taste.
The bike itself is great; lightweight, internal cable routing, good tires, nice rims., etc.
However I believe the controller in this thing is an absolute POS. I'm having the following issues with it:
I've driven a KIA eNiro, currently driving an KIA EV6, also tuned a Super Soco TS and as said now driving a Zero FXE so I know that EV's can be silky smooth and lethally fast and this thing isn't either of those (not that I need speed, but smoothness and predictability are nice, especially if someone is learning throttle control).
To clarify some I've made some video's:
Deadzone & throttle delay

Min speed, deadzone

Max speed (6 / 11 / 16 kmph)

Now for my question: What to do about this??
Like I said before I think the ESC is the issue here so would it be possible to swap it for a better example?
EDIT: Some notes I forgot:

However I believe the controller in this thing is an absolute POS. I'm having the following issues with it:
- Throttle delay. The accelerator has a delay of about a second or so making the acceleration very unpredictable and almost feel like a suprise.
- Deadzone. The first 20/30% of the travel nothing is happening.
- Minimum speed. In the fastest setting (mode 3) the minimum speed is about 8kmph which isn't very comfortable if you just want to cruise on a lower speed or take sharp turns. The minimum speed in the lowest settings (mode 1) is considarably lower.
- Max speed. The advertised speeds aren't reached with a full battery, flat ground, lightweight driver.

EDIT: Some notes I forgot:
- When we drive he always wears protection
- My son has a normal bike (Volare Rocky 16") and we use that for all day to day stuff. This thing is just to learn throttle control, go with us on holidays, bycling to grandma/dad, going into the woods with dad on his MTB. He will not become lazy, no worries.
