We are planning a month long trip around the US hauling our eBikes so we can ride various bike trails. My question is what if any, special accommodations I will need to make to keep rain and road spray off the controller base and the batteries. We will be carrying them on our Thule Easyfold platform rack which has worked great. I know the R & M manual says to remove the battery when transporting but since it’s locked on, we never do. We do remove the controllers when they are being transported. I’d appreciate any wisdom the group can share. Thanks.
