Interesting that they haven't replied back to me yet. Again, it is not their responsibility to lock any of those settings. Its the OWNERS of the bicycle that should be able to determine if they want to change them or not. The fact they sent out so many unlocked then decided to lock it should be grounds for some type of warning on their site. Really? Tire size is one they lock? That's going to affect the integrity of the bike? What happens if you decide down to road you want to go to a different tire size? Oh here are some numbers to maybe get you in the general area, lol BS. As I said, I can KIND of see the voltage cutoff in that they might have been able to set it to low but instead of locking it out they could have just set a minimum low voltage that wouldn't destroy the battery. Most of those settings would not affect the integrity of the bike.
I went through all settings today. The only ones you actually can change is 1,2,8,9,11 and 12. All others are locked. Including the suggestion of using 18 to modify speedo percentage or 17 to allow you to turn on cruise control to save cramping your hand on the throttle. I wonder how that could possibly affect the integrity of the bike or even safety in any possible way. Personally I think they took the wrong way about it and just locked out things so they wouldn't get calls on it when they could have just included a piece of paper with the default settings to it in the box or even the email they send you.
Is the bike a good bike, Yes it certainly is. Did I get the $900 bike I paid for? No. I got a crippled version.
Edit note, left 8 off, it can be changed.
