I am looking forward to the arrival of my 8Fun 500 W 48 v mid drive kit. It was ordered from EM3ev. This will be installed on a Trek Pure Sport vintage 2010. I took note and ordered a cockpit mounted electric brake which I had not seen before in my research phase of this adventure. It appears to be a motor cut off switch. When needing to shift I assume this will eliminate gear mashing. What I don't know is it a press and hold cutting power while still pedaling to make the shift, and then release to resume pedalec assist, or does this cut power with the need to reset the desired assist level? I suppose I would discover the answer at first use, but it would be nice to know prior to the maiden trip. There will be enough new experiences to process. Insert grin here.
