Thats is really interesting. I have to check that timer again. What I did is a fast cut in Adobe premiere and added a built in timer. Hard to count with youtube as you only can make it show seconds.
Edit: yep, something is not right with this timer. Real values if counting with Premiere timeline:
0-50=3.1sek
0-80=5,3sek
0-100=9,1sek
Now I need to unlock the controller to get to those wrong values
What is impressive is the work that the Adaptto OVS does! I have simulated your setup with the ebike simulator and your top speed is about 65-70km/h. But you can reach 115km/h withc is close to double the speed with the BOOST ( OVS) on the adaptto.!
One the simulator what is important is that at those insane speed (80kmh+) the peak power curve you get form the motor must be after your desired top speed since what count is to have the required power to get to these speeds, not the voltage or amp.. but both.
With the OVS it's like your motor become a 2T or 3T ( a kv of 12 to 18 after 70km/h)
I have simulated the same thing with my 5302. on a 20". lol.. a thin 32mm stator..!. and I get similar performance as your 5403 with 24". but this is probably due to 22s and the fact that it's a 18kv so it does not need the OVS to work so it can remain in a more efficient zone even at 100kmh. but it's a controller killer :lol:
By estimation, if it's linear.. well.. let say....... this mean that if I can get 10.5kW+ at 75%eff) with a simple 32mm stator... with a 40mm stator from the 5400 serie motor you can get easy 40/32=125% higher power.. .witch would be about 10.5x 125% = 13.2kW.
by unlocking it you will need to unlock the battery power witch is what limit your top speed... Phase power is only for your acceleration during lower speed.
But... I know that the adaptto use 10AWG wires to the PCB and mosfet "bussbar".. so this would need to be upgraded to avoid them to melt the solder where they attach. A AWG 8 would be perfect!
Look like it is not the motor that is the limitation but the controller batt current.
It would be good to see what a high kv cromotor ( 13+) would give with a batt current of 200A
