Just received my Moscow bike and I wanted to ask about the battery operation. Once the power button is pressed, the LEDs light up and never go off. I have to hold the power button down for 5 seconds to turn off the LEDs. I notice that when the LEDs are active, the battery is very warm around the power button. Just wanted to make sure this is normal behavior. It seems odd that the battery doesn't automatically turn off after inactivity like the LCD display does.
