Outrider proposed a simpler, smaller, lighter, and more affordable tire pressure monitoring system for bike tires. Designed to fit inside you tire attached to the base of your existing tubeless valves, this Outrider TPMS solution aims to bring live tire pressure monitoring within reach of a lot more cyclists. Bike TPMS does not have to be super expensive, bulky, and it does not need to be overly complicated. Just like most modern cars have neatly integrated TPMS into their valves, Outrider wants to give cyclists the same benefits without a lot of extra complication…

Keeping correct pressure in your tires is a matter of control, comfort, and ultimately rider safety. But in reality, a lot of cyclists don’t really check their tire pressure all that often. Or simply squeeze the tires to see if they ‘feel’ about right. And now that so many of us ride bikes with tubeless sealant inside, you could get a small puncture that fixes itself after losing a bit of pressure or even have dried-up sealant inside and slowly lose pressure over time without really noticing it. And of course, either scenario just increases the chances that you could get an unexpected flat while out on a ride.

But often bike TPMS is either costly, or clunky.

“The Outrider is there to make your life easier. Residing inside your tubeless tires, Outrider sends accurate, real-time tire pressure readings and alerts to your Garmin device so you’re always in the know.”

Why not take the guesswork out of the equation and let a set of low-cost and unobtrusive Outrider tire pressure monitors keep an eye on things for you.

Direct TPMS communication & alerts with Gamin cycling computers

  • pairs via ANT directly to Garmin cycling computers for live pressure and to send puncture notifications (and unofficially also Garmin multi-sport GPS watches)
  • currently limited to Garmin Connect communication to allow for live display of front & rear tire pressures, as well as to send puncture alerts no matter which data screen you display on your GPS

Tech details

Outrider TPMS, a lightweight affordable bicycle bike tire pressure monitoring sensor solution, min 19mm inner rim width required
  • installs inside your tires, e.g. on the base of most existing tubeless valves
  • requires valves with removable rubber valve hole seal (i.e. most newer insert-compatible valves)
  • fits inside rims with a minimum 19mm internal width
  • pressure reading functions independent of airflow through the valve
  • +/- 0.7% pressure accuracy from 0-39psi, or +/-1.4% accuracy from 39-85psi
  • not affected by sealant
  • ~2-year battery life with 1 standard replaceable CR1225 watch battery per wheel (830 riding hours)
  • 3.5g weight per wheel

Outrider Tire Pressure Sensors – Pricing, options & crowdsourced availability

This new lightweight low-cost Outrider bike tire pressure monitoring system is still in the midst of a Kickstarter campaign, where it has already achieved more than 22x Outrider’s minimum support threshold. Of course, supporting a crowdfunded project from a new company is nowhere near as sure as ordering from an established company. But it seems like Outrider has a reasonably-priced and relatively simple solution to bike tire pressure monitoring, and they certainly have enough funding to get it off the ground now.

There are still a few Early Bird deals left to get a pair of Outrider sensors for $55, or 30% off their ultimate retail price. Or 2 pairs for $89 for 44% off. And if you back now, Outrider says they’ll already start shipping the sensors in just a few months, in January 2025.

This is gonna be awesome once it works with other cycling computers

The last sensor like this on Kickstarter never shipped. All backer money was blown on R&D and the device never worked sufficiently well to enter production.

This one could work out differently, but no guarantees.

Yes, it was a shame about that, I backed it too. The problem they had was sealing the external unit, since this is internal and therefore doesn’t need to be sealed it should be easier (hopefully). I’m backing this one too and maybe one day one will make it.

The Outrider guys would really have to screw up to not make this viable, in my opinion. The PSIcle would appear to have failed because they had the high cost of a plastic injection molding tool, and the additional complexity of overmolding a sensor that all needed to be air tight. They had $39k. Outrider looks to me to be a simple circuit board that manages a coin cell battery, a pressure sensor (hopefully temperature compensated), an ANT+ transmitter and a small micro to run the show. They have $167k to bring that to production.

The risks in this design would seem to be the robustness of the circuit board to survive mounting and unmounting tires, protecting the components from tire sealer, and keeping the pressure sensor from getting plugged with sealer. The design shown on Kickstarter looks like it just has heat shrink tubing over the components, and it apperas you have to cut it off to replace the battery. If that’s the production design, that will be a bit sketchy, and battery replacement will not be possible for more than a few users.

Certainly looks less clunky than the external SRAM version.

I’m guilty of testing tire pressure by squeezing the tires before each ride. I’m also guilty of not always using a torque wrench, but that’s another story.
I think I would consider these some I could easily check tire pressure both before a ride and during.
I do wonder if you need to counter balance the wheel with these installed?

Theoretically yes, practically it doesn’t matter. You have to do it in car wheels because they spin way faster and have a heavier carcass so imbalances add up quickly. At 3.5g per valve I wouldn’t worry about it.

I might buy a pair for my road bike. It would be great to get notified of a slow leak when descending before it becomes a noticeable problem.

Nice that it can be installed on existing suitable valve stems.

I backed the 5 pairs fairly early on. It’s so nice being able to tap the valves and get down to the pressure you need while looking at the computer. I have been a Tyre Wiz user, but the price is insane and they aren’t even that good. Their low pressure measurements are a random number generator and the two sensors were rarely within 1 psi of each other. It burned through batteries like crazy too.

But…why?

I can feel when my tires are too low or going flat.

This is electronics for the sake of gadgetry.

No thanks.
