I was wondering if anyone uses one of those rearview mirrors that attach to your helmet. If so, are they any good for keeping an eye on cars coming up behind you? Moving at the speed I do on my eBike, I'm nervous about turning and looking behind me sometimes. Here is one I'm looking at: http://www.amazon.com/Race-Icon-Bike-Helmet-Mirror/dp/B00SXHQP4C/ref=sr_1_1?s=sporting-goods&ie=UTF8&qid=1456716014&sr=1-1&keywords=bike+rear+view What do you think?
