I had a similar change of heart about cycling to work after a quick succession of nasty close passes on my daily 20 mile round commute (which I had been doing for nearly 4 years). Abusive drivers put me off for the best part of a year, I'm only just getting back into it. Having an ebike has got me back in to the swing of the commute again, although I must say icy conditions will be keeping me on the bus or in the car, I'm a bit concerned about taking an expensive bike on black ice. Despite my new longer 30 miles route I'm riding again. Having an ebike means you can travel further and faster, so routes that were perhaps not practical before, might now be open to you? Despite the extra distance, I'm doing less miles on hostile roads, and I've avoided the worst sections of my route which helps with morale.
I honestly can't wait for spring to get back into daily cycling without the threat of ice.
