[QUOTE="entoptics, post: 1990046, member: 104268"] Yeah, but these are near silent... [ATTACH type="full"]216760[/ATTACH] I have a [URL='https://lunacycle.com/x1-enduro-ebike/']Luna X1 Enduro[/URL]. It's the bomb. [ATTACH type="full"]216754[/ATTACH] Something to be aware of, the quoted and/or extrapolated ranges are misleading.
