The PSIcle Alows You to Monitor Tire Pressure with a Smartphone

Any serious cyclist rider knows how critical tire pressure is for ensuring optimal performance. For that reason, Rover Development has developed the PSIcle sensor that allows cyclists you to check their tire pressure via a smartphone. 

The PSIcle sensor is a patent-pending lightweight NFC-based pressure sensor that measures tire pressure with extreme accuracy.  But, unlike other devices, it has no battery to charge or replace, which also eliminates extra weight.  The PSIcle sensor threads into any Presta valve, or with any tube with a removable core.  Moreover. it’s also fully reusable when a new tubeless tire or tube is replaced.  

The PSIcle sensor is simple to install, by removing the valve core of the existing Presta valve, thread it into the valve in place of the core, and thread the valve core back into the top of the sensor.  

To read the sensor, all that’s required is to hold an iOS or Android smartphone within an inch of the sensor.  The NFC reader inside the phone automatically powers and wakes the sensor.  Then the free PSIcle app detects the sensor and automatically launches, providing an instant and incredibly accurate pressure measurement. Pressure readings are updated even as the tire is inflated.

There are two models of the PSIcle sensor.  A low pressure sensor for mountain or fat tire bikers that measures 0-40 psi and a high pressure sensor for road bikers that measures 0-400 psi. Rover Development claims the high pressure sensor is accurate to within +/- 0.7 psi, and the low pressure sensor is accurate to within +/- 0.06 psi.

Rover Development is comprised of three engineers with over 60 years of cumulative product development experience who have experience in working in organizations from startup to large corporations.  Collectively, they have brought over a dozen previous products from concept to production.  They will leverage their prior experience to bring the PSIcle sensor into production.

The PSIcle sensor Kickstarter campaign launches on May 25th, with an early bird price of $52 for 2 sensors delivered in September, 2021, and a regular price of $56 for 2 sensors delivered in November, 2021.  Sensors will be sold direct through Rover Development’s website after a successful campaign.
