New stem cap phone mount from F3 Cycling launches on Kickstarter

"The phone mount to end all phone mounts" attaches to your stem cap and has a square dock with powerful magnets to attach your phone. The Kickstarter will launch on 17th April

US innovators F3 Cycling are crowdfunding on Kickstarter with a unique new take on the bike phone mount. Attaching to your stem cap, the mount then sits on your stem and uses powerful magnets to hold your phone in place, vertically or horizontal.

Described as the "bike phone mount to end all bike phone mounts" by F3 Cycling, they claim it can be stuck on your bike in under a minute and angled and adjusted to your preference. The design makes it universal, with four neodymium magnets creating a super-strong docking solution for your phone, with just a twist and lift required to remove. They do recommend that the case plate attaches best to plastic or metal phone cases rather than silicone or soft touch versions.     

The magnetic technology appears on F3 Cycling's out-front mount solution, the Transform Form Mount, and they also produce a Garmin and Wahoo-compatible GPS mount claimed to fit almost any four bolt stem.  

You can get a heavily discount Stem Cap Mount by backing F3 Cycling on Kickstarter, where you can reserve yourself one for $40 with a Super Earlybird discount. Check out F3 Cycling's website for more info. 


Arriving at in 2017 via 220 Triathlon Magazine, Jack dipped his toe in most jobs on the site and over at eBikeTips before being named the new editor of in 2020, much to his surprise. His cycling life began during his students days, when he cobbled together a few hundred quid off the back of a hard winter selling hats (long story) and bought his first road bike - a Trek 1.1 that was quickly relegated to winter steed, before it was sadly pinched a few years later. Creatively replacing it with a Trek 1.2, Jack mostly rides this bike around local cycle paths nowadays, but when he wants to get the racer out and be competitive his preferred events are time trials, sportives, triathlons and pogo sticking - the latter being another long story.

Hey Simon, it's Mike from F3 here and I totally agree. That's my bike and I couldn't think of a better bike to showcase our new mount.  Really looks great on there.

Nice enough, but I found I really just wanted to see more of the very neat Spot Ajax it's featured on in the first video. Gates carbon / Alfine 8-speed / disc brakes - and just $1,700. Perfect commuter.
