Well, this is a first. Just about freezing here but due to join your temp zone shortly. Tested out the e-bike on a light snow today= severe wheel spin starting out, rode a hundred feet and put it away.
That tensioner is a big topic here. Some like to drill a little hole and put a locating screw in it, so it can not twist into the spokes, others eliminate it by using 1/2 links ( I think). Did see a couple spring jobs too.
