Seriously, who wants to inflate mountain bike tire with a floor pump? It’s OLD-SKOOL (do we need to mention we’re being sarcastic here?). Let’s make things right and install an on board tire inflator. We’ll be using the air compressor from our Air-Lift suspension system.

But before we get too excited, there are a few things to know:

1. We tap into our Air-Lift suspension system. We have the stock Air-Lift air compressor: it’s a mini-low-volume compressor, MINI-LOW-VOLUME. Don’t even try to inflate a car tire with that, the compressor will toast.
2. A normal air-compressor has a large air tank. In our case, the air-bag acts as the air tank; it’s has a very small volume so after a few PSI is added to the tire, the compressor will kick-in. And there is few seconds delay for the compressor to kick-in. It’s not as sleek as a normal air-compressor system. 
3. We operate our Air-Lift at 60PSI, which is more pressure than we inflate our mountain bike tires (28-30PSI max).
4. The Air-Lift maximum pressure is 100 PSI. Sorry roadies, no tire inflator for you.
5. And finally, when inflating a tire, the Air-Lift system will think that there is a leak. Of course, we’re taking air away from the Air-Lift system, just as a leak would do. The Air-lift remote will therefore display a “LEAK” warning, but it will keep working, so we just ignore it.

In other words: MANAGE YOUR EXPECTATIONS! It works great to fine-tune the pressure in your tires (we run tubeless, so we frequently have to add a few PSI and it’s much better than using a floor pump), but has some limitations.

 

Alright, still with us? You might want to buy a real portable compressor (with a tank), do this upgrade like we did or keep pumping air like a LOOSER (here is some sarcasm again). You choose.

 

 

TIME SPENT ON THE JOB: 2 hours (assuming you already have the Air-Lift System installed)

First of all, plan your routing. We tapped into our left air-bag, because this would make the shortest run from the Air-Lift to the tire inflator. Here is the final result:

 

LET’S DO THIS!

Using the Air-Lift controller, reduce the pressure to 5 PSI (that’s the minimum pressure) so you don’t get blown away when cutting the air line:

 

Using a carpenter knife, make a nice and straight cut into the air line and install the Union T (it’s a push-to-connect (PTC) fitting; just push straight and that’s it!):

 

Route your new air line from the Union T to the back of the van (or where you chose to install your tire inflator). Here is our routing:

 

 

The following fittings are added in this specific order (refer to picture below):

• Valve (we were concerned that the tire inflator would constantly slowly leaks, turns out it doesn’t. We would still install a valve to shut it down for winter or if a leak happens in the future. We don’t want our Air-Lift bags to deflate.);
• A short air line run (like 2 inches);
• Push-to-connect to 1/4″ NPT adapter;
• 6 feet (or else) Air Hose with 1/4 MPT ends (use teflon tape!);
• Quick Connect Air Coupler (use teflon tape!);
• Bicycle Tire Inflator for Presta and Schrader valves.

 

We’re using a Quick Fist Mount (Buy on Amazon) to hold the air hose in place:

 

 

NICE!!

 

 

ON SECOND THOUGHT

Please read the introduction on top of this page! We think the tire inflator is a great upgrade, we use it very often. But don’t expect it to work exactly as a normal air compressor system!
