Hi,
Ok, I'm on day 5 of E-zip bike commuting (8 miles each way). I was frustrated because the standard pannier racks would not fit, they wanted to clip on to the missing piece of the rack missing for the battery. So... I devised a low tech solution involving a wire closet basket, 4 hose clamps and a wire cutter to cut out an opening for the battery. So far so good. See attached picture if you want to see the beast
