Hi there, I purchased a Haibike All Mountain Pro 2016 and got it about 3 months ago. I absolutely love the bike and I'm always looking for ways to improve. Specifically, I like many others, want to find a way to go beyond the 20mph limit. I have tried the Dongle in the past(this is my second bike) but not crazy about the change in display and in addition, kept causing 503 errors(speed sensor and nothing was wrong with the speed sensor(I changed it and tested it) and the errors continued until I finally removed the dongle. So, my question. I understand there is a Pedelec-S version that goes to 28 mph. Is there a way to purchase that engine as a standalone and swap it out for my current one on my All Mountain Pro? While I realize that will be costly and not ideal, was just wondering if it's even possible?
