Is there a cheap and convenient way to have a front/back camera on your bike, yet? Or a bike helmet with inconspicous front+rear camera? I'm aware of the Garmin Varia line, but it's quite expensive and I don't care about the radar.

Also expensive, but the best options for cyclists are the Cycliq front and rear cameras/lights. They're best fitted to the bike and provide excellent footage along with being easy to manage (they overwrite old recordings automatically unless they're marked as being an incident where the camera goes onto its side).

Helmet cameras may compromise the "protection" provided by a cycle helmet though cycle helmets are next to useless in a multi vehicle collision anyway.

You can just get some ball mounts and an action camera or two. The new cameras have such good stabilization that a handlebar mount is very acceptable now.
