After receiving my first bike today, and going through the menu settings and reviewing recent past posts, it looks like new units arriving have some menu settings locked and not able to be changed. There have been several posts with individuals not being able to change wheel diameter. While I am ABLE to change other parameters, WHEEL DIAMETER CANNOT BE CHANGED.
I did read and other ebike forms that individuals have been grossly understating wheel diameter in order to obtain higher Max speeds. Perhaps this might be a reason why it is now locked down.
I also found a new default level in p15. P15 is now set for 40.0 volts and can't be changed, earlier bikes were set to 41.5 volts. Current limit, P14, is locked as well. I wanted to trim that down to 15 amps to keep the motor a little cooler.
In addition to some settings being locked down, New units are arriving with different latching mechanisms. The new latch sticks out 1-1/4" from the frame and has a 5/8" open throat from the frame. With the latch being so far away from the frame this is a potential catch point.
