波兰采购需求：亚马逊电动自行车、Ebike Connect、电动自行车、Stromer 自行车、Townie 电动自行车、三轮电动自行车

I bought an electronic bike through a Chinese platform in 2022, but I'm having trouble reaching out to them. Unfortunately, I've lost the user manuals and urgently need a replacement. Additionally, I require the app's name and QR code to control my bike via my phone, as I can't find this specific Chinese app in Europe. The bike was shipped from Germany, and your assistance would be greatly appreciated. If you could provide the manuals and app information, it would really help me get back on track with using my bike properly. Thanks in advance for your help!
