That is why I started narrowing down by motor reputation and support. The reason I bought the vado (despite all the trouble) is I ruled out bafang due to lack of local support (ruled out evelo). Down to 2 bikes: gazelle c380+ HMB (bosch) or vado 5.0 IGH (brose). I can't try the actual model of either before buying and there are a few things about the vado that I thought fit me better and or seemed like a bit of an upgrade over gazelle. Plus, the vado 4.0 I did ride was about as comfortable a bike as I have experienced. And, despite being lower on torque, there was something about the way the 4.0 responded that simply put a smile on my face. The serial 1 rush city also did that (but wasn't quite as comfortable).
I do wish the vado had the option of a second battery. But, it's "smartness" may train me to ride more efficiently both for my own energy and battery life negating that desire. We shall see.
I am less concerned about enviolo heavy duty. I also think the automatiq system is going to act as a natural defense for both the motor and the gear hub. It basically isn't going to let me mash the gears. Period. I either ride at a lower cadence in a lower gear or a higher cadence in a higher gear. I suspect that, in itself, is going to defend the bike from an abusive rider.
