My Turbo Vado has arrived. It is a beautiful bike. I bought it used from an online dealer and I found a few problems. The biggest issue is my battery I cannot get it to unatch for removal. The key turns clockwise to full stop. There is no unlatch click, no pop-up of the battery, and no movement of the battery. I watched a number of online videos. My key is turning completely horizontal as it should but to no effect. I tried applying pressure to the battery to unload the latch. I tried tapping the battery with my palm. I turned the key as hard as I dare. Has anyone overcome a stuck battery? This is a used bike with 190miles in excellent condition. It is possible that the previous owner never removed the battery. Thanks for any comments.
