Who Will Invent a Rear View Display For Cyclists?

None of the mirrors I’ve tried work all that well. Yet seeing what’s approaching can be very useful to saving one’s skin.

Who out there will invent a rear-facing camera that displays its image on a 2" LCD mounted on the handlebars? I thought of this idea several years ago, but decided against pursuing it.

It can’t be that hard— it’s essentially a closed circuit TV technology. Even a black and white screen would be just fine (and perhaps better). Anything highly readable in sunlight and with good battery life, and a 5 minute recording loop with enough resolution so that it can also be used as evidence in case of an “accident”.


Update to update! See this page for some very cool photos and specs, which indicate a system weight of 150g, battery life of 13 hours, speed, distance, GPS, power, etc, a price of $499, but no word on availability.

Update 2: I received this disappointing response from Evan Solida in response to my query to Cervello:

“The company is shuttering”

Cervello Hindsight 30

Reader Tobias L pointed me at the Cervello Hindsight 30 Digital Bicycle Mirror. I’ve inquired to see if they’ll send me a loaner unit for evaluation.

According to Cervello:

  • 3.5" Transflective LCD.
  • Up to 13 hours of continuous use on Lithium-ion battery
  • LED tail-light and head-light
  • Lightweight design.
  • Fits 26.0mm and 31.8mm handlebars
  • Camera fits aero seat posts as well as 27.2mm and 31.6mm diameters.

It’s annoying to see a meaningless claim like “Lightweight Design”: what’s wrong with stating the total extra weight when mounted?

My immediate comments are that it looks relatively large and heavy, and the two mounting clamps could be problematic, since the clamps use premium handlebar space.

Also, the display sits right where my SRM Power Control 7 lives, and does not look to be removable without tools. But this would not be an issue for many riders.

I’d want to know how the camera fares in rain and bright sunlight and glare, at night, etc. As well as battery life, and how readable the screen is in bright sunlight. It’s too bad it can’t double as a cycling computer as well.
