Hey guys picked up my new Stromer ST2 yesterday. Had to drive about 2 1/2 hours to save me a few bucks but it was worth the drive. At first I liked the white color version but I opted for the black color version instead. More "manly" looking, lol. Anyway, I got home, placed it on the charger. About 30 mins or so later the battery charger indicated that the battery was fully charged. Disconnected the charger, put the bike to sleep. Got up this morning all excited to use the bike, but for some strange reason the battery was completely drained. I contacted the dealer that I purchased the bike from and they asked me to remove the battery and re install, so I did but the battery was still dead. So I recharged the battery recently. Hopefully this doesn't happen again. But I'm concern about this since this is bike is brand new, anyone experience this issue before? Lastly, looking at the Abus locks, some of the locks come in different size so what size would be ideal for this type of bike?
