Replace your CO2 pump? Cycplus AS2 Pro Max REVIEW | Tests on lots of different tyres

[@MYnextDIYbikePROJECT]

This is a very reasonable product. I’ve used both co2 and mini pumps, and both have their limits and downsides.

[@MTBs]

More usable than I first thought.

[@mtbboy1993]

You should compare them with Fumpa if you can. At home I use a Makita inflator. But I like a smal pump like this on rides, just have to remember to charge it.

[@MTBs]

Would like to test a Fumpa pump too. But in the end I think they are very similar.

[@mtbboy1993]

Have you tried it in subzero temps? how long does the battery last? @@MTBs

[@MTBs]

No, only the small one in +5 degrees. That was fine. Like with all electronics you would probably want to carry it close to your body if it's very cold to maintain proper function.

[@mtbboy1993]

@@MTBs Fumpa is fine, even in - 10c.

[@MTBs]

Have to test when it gets colder, but I rarely bike in -10 degrees.

[@ERIN478]

Is there a way to stop the very loud, purposeless buzz on the Pro Max?

[@MTBs]

Don't think so. It's a proper compressor after all and they tend to be loud in general.

[@aceshelman]

So how many MTB tires will each pump fill? I

[@MTBs]

AS2: +2 large MTB tyres from completely empty AS2 Pro max: +4 large MTB tyres

ive been using a generic pump like this from amazon for 2 years. it was 35 bucks. about the same as a floor pump.

[@MTBs]

Great that it works for you. But you can always get cheaper stuff from Ali or Amazon no matter the product. A wild guess is that a Cycplus or a Fumpa holds up better over time and perhaps have better performance/capacity.

[@technodrone313]

mine gets me several inflations on a charge after 2 years. i top it off once a month. this is just like headlights where bike manufacturers will milk you. @@MTBs
