battery key reminder

I rode 4-5 miles yesterday and stopped for a few minutes putting by bike in "lock' mode. When I returned to resume my ride, I could not get any response from the button used to start up on the bottom of my top tube of my ST-2. Fortunately I had the key to the battery compartment with me and removing, then reinstalling the battery solved the problem (at least at that moment!). I am happy that someone had previously posted this reminder at an earlier date on the forum...don't leave home without it. I also occasionally forget to recharge my phone some evenings, so I decided to throw a charger chord into my rack pack just in case I ever get caught out with a dead phone while riding

The same thing happened to me today. I could not get the bike unlocked. I called the shop and they could not do it from their portal so they called the rep and he did it from his portal. The electronic glitches on this bike are many so I will always store the key on the bike. Some other things would not work when I got the bike a week ago and the shop could not get them going so they had the rep do it from his end. This part of the bike has me creeped out, it's like no one understands how the bike works especially the dealer I bought it from.

It happens again, this morning I am turning on the bike and it says, battery 0% charge. So I unlock the battery and remove and reinstall it and now I have 100% charge. Dealer offers no remedy.

Unless the dealer has been trained by the Stromer folks, the electrical problems one might encounter are probably well out of his ability to deal with. As the e-bikes gain in popularity I am hoping that conventional bicycle dealers will gain more knowledge and expertise regarding the electrical piece of the bike...we'll see, I guess. In the meantime, I can only tell you that my experience has been a bit similar to yours. I walked out one morning to go for a ride after charging the bike the previous evening and got the 0% battery reading which of course jumped to 100% after removing the battery and reinstalling it. Quirky, for sure, but I liken it to having to reboot my computer from time to time because it too is acting a bit quirky as it were. So far that has worked for whatever problems have occurred. This leads me to ask whether you charge the battery while in the bike or outside of the bike? I try to always charge it in the bike, thinking that constantly removing, then reinstalling the battery breaks the electrical signal and will also wear on the connections on the battery and at the terminal it plugs into on the down tube? I have no scientific evidence of this whatsoever, just my own personal way of looking at it...if I were to face the problem you describe on a regular basis, I would use a soft brush on the terminal battery ends to remove anything that might be impeding a good connection and would probably use some kind of blower (vacuum or hair dryer) on the lightest possible setting to try and push a little air into the down tube, hoping that it would remove anything at the bottom which might be impeding a good connection. I guess that an alternative might be to remove the battery, then turn the bike upside down and try to gently brush the battery connection in the down tube to remove anything that might be impeding a good connection. My best guess is that you have to be pretty gentle in this regard, but it doesn't take much to run into a bad connection from time to time. Then too, you may find that after reseating the battery 5 or 6 times, the problem disappears? I'm thinking that is what happened in my case on a few different occasions and now (knock on wood) the electrical system seems to be running well. I must also add that I only recently, with a good deal of trepidation, removed and then reinstalled the rear wheel (which was quite an experience in itself), worrying that I would for sure bollox up the electronics. I didn't, much to my relief...don't give up yet; hopefully the problem will disappear as you ride and try different approaches to solving the problem. And of course, there could be something that only a Stromer dealer who sells and works on the bikes themselves can solve if the problem does nor abate...

We've all waited on hold forever just to hear "unplug it for a minute, then try..... Reboot"
Mine has done the 0% thing a couple times...... And I fix it just like Verizon, Apple, cox and Microsoft have trained me. Reboot. Don't forget key.:)
