Hi, I have an A2B Velociti and I am having a problem with the bike battery On/off button. I usually go to turn the battery on by pushing the on/off button in and it stays in and the bike has power. Now when I do it the button pops right back out and I have no power to the bike. But when I hold the button in and pull the throttle the bike goes. Is there a way to fix this? Do I need a new battery...I hope not? A new button? I attached a photo of the button below. Please let me know. This bike is my transportation to work everyday and need it fixed ASAP. Thank you so much.
