The three speed switch works as follows:
in position 1, it shorts ground to X1 pin (blue wire) on the board and enables whatever percentage you set for Power level 1 in the app.
In position 2 or mid position, ground is not connected to either X1(blue) or X2(gray wire) and that enables Power level 2 configured in the app.
in position 3, ground is connected to X2 and that enables Power level 3 configured in the app.
So you can configure three different power levels for three positions and switch between them on the go as appropriate. I usually configure them this way:
Set power level to 15%, level 2 to 50%, and 3 to 100%. I use level 1 or first position of the switch to ride where extra caution needs to be used like if there are pedestrians nearby. I use level 2 for effecient high speed cruising, and I use level 3 when I want all the power I can get like off road or getting to the top speed. I recommend leaving all the speed level settings at 120% and use only power levels to adjust power with thethree position switch.
Regarding the throttle response, it can be adjusted via the Android app. There are hidden extra settings that you can activate by pressing and holding the regen on/off button in the app. You will get extra settings unlocked. To set the controller for soft start, move the "Soft Start Time" slider all the way to the right and click the button turn it ON.
Here is the visual:
Using this in conjunction with three 3 speed switch should give you pretty good control over power during acceleration.
Regarding regen, all you need is an on/off switch on one or both of your brake levers that can connect EBS_ to the ground when brakes are activated.
Resistive throttles like Magura or Domino should work fine out of the box. The only thing is that you may get some dead band at the lower and upper positions of the throttle as the controller active band is between 1.25V to 3.3v. It's a good practice to add a resistor in line with 5v input from the controller to the throttle to drop the voltage to something like 3.5v. I've seen values between 560Ohm to 2K have been used. Maybe start with 1K and see if yo need to go up or down to get about 3.5v at in the fully open position of the throttle. Of course, disconnect your motor as you do the testing.

How does 3-speed switch connection work (wiring)? Ordered this: http://www.ebay.co.uk/itm/401331618199 but it will take 2-4 weeks to arrive, so planing a temporary solution. Throtle response when 100% is quite rapid. When driving at woods or in city slow speeds u need to be extra carefull that u wont filp the bike...
Question about brake and regen. Previous connection (max-e) was with domino throttle: https://www.dropbox.com/s/csbumbpqyi01baf/2017-06-25%2021.37.54.jpg?dl=0 brake was linear: https://www.dropbox.com/s/y4y2w70qzg326rn/2017-06-25%2021.38.09.jpg?dl=0 I don't have a glue how to connect it? I don't need it to be linear just on/off is enough but would be nice to get it working with those parts allready installed to bike.
Domino wires are white: 0V black: pot wiper and blue 5V (s399.photobucket.com/user/rayivers/media/Throttle%20Replacement%20Schematic%202%20Domino%20-%20Magura.jpg.html )
