Are you wearing a motorcycle helmet? My bike helmet doesn't touch my ears and weighs around 300g, about 5% of the 5 kg weight of a human head -- I can't tell the difference between turning my head with and without a helmet, but it doesn't matter much on the road since I use a rear-view mirror on my glasses so I look behind me much more often than if I had to turn my head every time.
- gpm 7y agoNormal cyclist helmet. It causes more wind noise and generally messes up directionality because there is something above your ears. A rear view mirror might change my decision, I keep intending to try some of those out.
- jackcarter 7y agoI built one myself with some spare parts. I love it, to the point that I wear my helmet for short trips when I otherwise wouldn't bother. It's modeled after this one: https://www.efficientvelo.com/home/safezone https://www.efficientvelo.com/home/safezone The key component is the flexible, stays-where-you-put-it arm. Safezone is repurposing an industrial product called "coolant hose" - a 1-ft length costs less than $5. Epoxy a small mirror to the end, and attach it to your helmet with zip ties or velcro straps. Here's mine: https://imgur.com/a/a9H7bXq https://imgur.com/a/a9H7bXq
- Johnny555 7y agoI tried some helmet mounted mirrors, but they moved around too much for me, so I switched to this eyeglass frame mounted mirror: http://travellingtwo.com/resources/take-a-look-mirror http://travellingtwo.com/resources/take-a-look-mirror It's simple to clip on, and stays put once it is, I've been using this mirror for over 5 years and feel uncomfortable riding without it.
