Hi everyone, just got my new ebike with Bafang BBS engine 250W and 55Nm (dont know the exact type yet but I ordered a bafang cable), and I'm bit confused how it supposed to work. I feel it doesn't have that smoothness of driving comparing to my mate bike, which go Bafang 250W 100Nm, but just want to be sure.
I wanna asku you guys what you think. First of all: the start is quite smooth, bike is gathering the speed all right and then it kicks suddenly, like a turbo car at some point of rpm.
The problem is when I stop peddaling for few seconds while riding, then when I start peddaling back again there is nearly no power. It switches off but when I need to speed up again I have to wait maybe like 8-10 second before it slowly gets back to full power. Is it normal for this engine? Which parameter in bafang programming software is responsible for faster engine reaction after stop peddaling?
Thanks for any sugestions.
