Folding bicycle helmets are not a new concept, nor are electronically-enhanced “smart” helmets. The Woolf helmet is claimed to be the first product to combine the best features of both types of helmets into one wearable device.
Currently part of a Kickstarter campaign, the Woolf helmet was invented by British cyclist and entrepreneur Jeff Woolf. He previously introduced the “non-smart” folding Morpher helmet.
Similar to the Morpher model, the Woolf helmet functions like a regular ABS-shell helmet when worn. However, when you take it off and want to store it in a bag, you simply push in on it from both sides with your hands. This action activates a magnetic quick-release mechanism, allowing the helmet to fold down to a width of just 3.25 inches (83 mm) in less than one second.

Although the helmet can fold, it is still considered safe, with Jeff Woolf mentioning that it will receive CE EN 1078 and CPSC certifications (for Europe and the US) before being shipped to supporters. It features an impact-absorbing expanded foam liner and includes a MiPS-like Energy Reduction Technology (ERT) system that uses polymer pads to reduce rotational forces upon impact.

So, what makes it smart?
For starters, it includes lights. There is a wrap-around strip of white LEDs in the front and a strip of amber LEDs in the rear. These LEDs are not just for illumination; they also serve a purpose.
Thanks to an integrated IMU (inertial measurement unit), tilting your head twice to one side causes the lights on that side to start blinking, acting as turn indicators. The IMU also detects sudden decelerations, causing the rear LEDs to illuminate brightly like a brake light.
In addition, if the IMU recognizes a significant impact on the helmet, it will activate an app on your connected smartphone to alert a predetermined contact and emergency services with your location. The app includes a 30-second delay before alerting, giving you a chance to prevent a false alarm.

All the electronics are IP65 waterproof, meaning they can withstand low-pressure water jets from any direction. A single 1.5-hour charge of the 500-mAh lithium-ion battery should provide 2.5 to three hours of lighting. The entire helmet is said to weigh between 1.2 to 1.27 lb (550 to 580 g) depending on the size.
If all goes well, a pledge of US$99 will get you your own Woolf helmet – the planned retail price is $219. The helmet’s features are outlined in the following video.
