Welcome to Grouphunt    Learn how it works!

Few things are as good as listening to music, reading messages at quick stops and checking the best way to go on a GPS app while you're riding a bicycle.

Our motivation to develop Pully was born after many frustrated experiences trying to use some other phone mounts. We tested several models and even broken glasses/screens.

Today all options available on the market have many moving parts, connections, settings and use low-quality materials:

Our goal to develop Pully was based on 3 main requirements:

  • No moving parts or adjustments; 
  • Easily removable if needed; 
  • Practical use: just one hand. 

After 6 months of design and testing we got t the following result:

The most notable difference, compared with other models available on the market, is the size:

With a few grams of the magnet, we generated enough force to lift a 16lb watermelon. Most phones on the market weigh between 0.2 and 0.3lb.

Pully is waterproof and there is no need to remove it when parking outdoor. It was designed to go along the daily rush:

One of our main design criteria was to ensure devices would not be affected when exposed to the magnetic field, short or long term. After several studies, we conclude:

The vast majority of phones launched since 2012 has memory, display, processing, battery and touch-screen immune to changes in the magnetic field. Only phones that have the compass feature may have the function affected when close to Pully, but return to normal when distanced. GPS applications like Waze and Google Maps work normally.

If the magnetic field of the permanent magnet was about 85 times, the first affected component would be the speaker that could sound distorted when close to the magnetic field.

Despite the great magnetic attraction between the device and Pully, the secret to easily remove is this small rotation:

The elastic absorbs all vibration that would go to the phone if it was a 100% rigid structure.

Phone usability is not affected at any point (unless the "compass" app only while the cell is in the holder). GPS navigators (Waze, Strava and Google Maps for example) work normally.

The compass feature depends on the magnetic field of the earth, so it may have its precision affected while the phone is mounted on Pully. As soon as you separate both, compass goes back to function normally.
