Hi, I purchased a 2017 Stromer ST1X, I did not get a key or charger, long story. When I reached Stromer by phone they told me I had to go through a dealer, which I have. I contacted a Stromer Dealer, All Wheel Bike in Bethesda MD. The tech has the same bike, and assisted with getting me a charger and clean history from Stromer. Got the bike charged and it ran great. Only had 160 miles on it. I put about 500 miles on it in 3 weeks. I went for a ride a couple of days ago, it was the first hot day. Came back home, plugged in the charger, a few hours later came back out and the bike ran, but only feels like 1/2 power. I did a reset on the controller and also tried a manual reset of the torque and regrenative brakes. No luck it just feels like a very minor boost as opposed to how it previously felt. I've been in touch with my mechanic at the Stromer dealer and he said he is waiting to hear back on my key....It's been over a month with no response. I spoke with him the other day, and all I got is he is waiting to hear back from Stromer, but has no idea when or even if they will be able to assist with a key, due to the limited number of people who are Stromer employees.. It's one of those round keys and I already had a locksmith look at it and he said it is some sort of special size lock that he was unable to pick with his tools. So the first problem is getting a key to open the battery compartment , then diagnose the issue. And the second problem is the 1/2 power? I've got a 12v test lite and a multimeter. Not especially experienced in electrical repair or diagnoses, but certainly willing to get into it. I just don't have a real starting point. I asked the mechanic about the issue and of course, well without seeing it type of thing. I understand that. The dealer is like 300 miles away. It's this especially slow or no response time that makes me question any long term ownership of this bike. It's a great riding bike, super solid, I really like it, and fast. It's summer now, just bought a second eBike for Mrs. so we could ride together. So, if you've read this far, you can most likely feel my frustration. I'm sure once straightened out the bikes not going to be problematic. But really hate not riding, as I am out of work now, pretty bored. At this point I'm wondering about just drilling out the lock and getting some aftermarket components. Yes, I've tried to call again and left many messages, and email Stromer, several times and no response from them. Any type of input or suggestions, or anything would be greatly appreciated.
