Review: Cerevellum Hindsight 35 Rearview Biking Computer

Next Story

In Praise Of Quick And Filthy

We’re very lucky that the creator of the Cerevellum is even alive. Evan Solida was a competitive cyclist until a major accident in 2007 left him unable to ride. After years of plastic surgery and physical therapy, he was able to get back onto his bike and now builds unique cycle designs, does contract work, and just released his first product, the Hindsight 35.

This unique device is essentially a rear view monitor and race computer for cyclists. It connects to various sensors using ANT+ wireless technology and a small lens and light combo on the back of the bike gives you a full view of what’s coming up behind you in brilliant color. The device also records the scene in five minute bursts and stops recording when you (or your bike) are suddenly interrupted by a collision. In short, it’s a way for cyclists to find out what’s behind them and, if they run into a spot of bad luck, see who’s responsible.

The device itself is essentially a 3.5-inch screen mounted to your handlebar with a cable that connects to the camera. An optional heart rate monitor and speed sensor allows for on-the-fly measurements that appear on screen as you ride.

To be clear, the Hindsight 35 is a shipping product but is more of a beta product. Because Solida designed, built, and manufactured this product himself, it’s definitely not fully-featured just yet. Luckily, the device is fully upgradable and future systems will include a GPS chip – there’s a place on the circuit board but it’s not yet installed.

A bundle with heart rate monitor and speed sensor costs $363.50 and the device itself costs $299. It also lets you record rides – albeit in rear view – with the press of a button.

I tried the Hindsight in the crowded streets of Brooklyn and I’m happy to report that it really works and it makes me feel just a bit safer. Riding down 65th Street near my house is always a wild experience but this let me see who was about to pass me and where I was in relation to other cars. Sadly, the transflective display is great in sunlight but nearly disappears when you’re wearing polarized glasses so you either have to look around your shades or eschew them altogether. Regular shades work fine.

Cerevellum is a true hardware startup built by a guy who knows his stuff. His story – and his hardware – is inspiring and his rearview is well worth the price, especially for biking gearheads like me.
