Mini Electric Tire Pumps

What options have people found for frame mounting these? The internal storage on my speed concept has a spot for co2, same with integrated rear hydration systems like Topeak. I have minimal pockets on my trisuit so it would be nice to see some integrated options for race day.

So I need to buy an electronic pump to go with the CO2 cartridges and the hand pump and the spare tire and the credit card and £10 note for the taxi home :joy:

All i can say is last year during group rides we had (2) events where someone flatted and whipped out a electric tire pump just to find out it was dead for whatever reason (probably sitting so long).

Each time I had to use my Co2’s to fill the tires, that’s the only feedback I can give is its just something else you need to remember is charged.

Maybe a 3d print option that mounts to a Garmin mount. A case like for a go pro sort of thing.

Has anyone tried the Prestaflator? I like that it allegedly inflates 7 plus gravel tires on a charge. But maybe too big??

I ordered one that’ll be here Tuesday, allegedly. After a work trip where I brought my bike I thought one of these will be nice for travel. Use case is intended to be ā€˜pressure gauge with a pump’ more than an emergency kit.

I’ll report back. I like prestacycles chucks, and this seems to have a nice combo of specs and a gauge.

USPS misdelivered the package, so I just got the PrestaCycle inflator and tested it in the garage just now.

My ā€˜daily’ inflator is the prestacycle digital gauged inflator that’s connected to my 30gal compressor in the garage. Very fast, silent, and accurate (tested against an accu-gauge dial pressure gauge and a silca track pump). I liked the Prestacycle inflator and chuck and that directly influenced this purchase. My wife prefers the Silca track pump, so if I take a bike for work trips I end up with a Lezyne floor pump that I hate. I thought this electric inflator would be a quick grab-and-go for that sort of trip where I’m taking the bike, but don’t want a lot of extra ā€˜stuff’ to pack.

Initial thoughts: It’s loud, as expected, but pretty small. I’d say ā€˜thick cigarette pack’ sized, and it wouldn’t be bad to stash in a little frame bag or something. It’s certainly lighter and smaller than my OneUp 100cc pump. I inflated a 28mm road tire 0-66psi in maybe a little over a minute. I topped off a MTB tire a few psi, then ran a 2.4 mtb tire from 0ish to 25psi. It was hot after that…expected. The major issue was when I checked pressures with the Prestacycle digital inflator and my Accu-gauge. The gauge on the electric inflator is not accurate. On the MTB tires it overinflated by 3-4psi. The road tire was over by ~2psi. This is going to require a separate gauge to validate pressures on MTB and gravel. I’m really disappointed in that. Paperwork for the inflator says ā€˜Precise digital gauge’…so no accuracy guarantee.

I’ll give it some time and try to work the gauge delta to see if it actually is ā€˜precise’ once I figure out an offset. It’s clearly not a percentage offset, so it’s probably fine if you’re at road pressures. I sort of wish I’d just gone with the Fumpa so I could take it apart and replace a battery if/when needed.

I’m using this one - Ā£52, with a 5 year warranty. Looks to be the same as the Cycling Cadence one. Inflated my tyre twice and had about half battery left.
Tiny, about 128g. Works really well.

Tried two cheaper models from Aliexpress, Rockbros 150 psi and Cyclami thing, both useless.

All the pumps I and my training partners have (few different brand’s) have held up to be as splash/sweat proof as a smartphone in the winter. I’m less waterproof than them it seems, and theyve lasted climbing in the summer heat as well.

Smartphones are very waterproof. Just yesterday we got caught in a summer rain (forecast was for hours later). My phone got so wet in minutes that it wouldnā€˜t unlock (iPhone, Androids/Google seemed to work, probably too much water over face id camera). Also it wouldnā€˜t allow to charge till this morning because the charging port was too humid.

I expect the same from every equipment I have with me: Garmin and lights never had a problem.

I would like to see an electric pump that is really jersey pocket suitable. The current pumps are IMO still too big to comfortably carry them in your pocket.

This might be of interest to some

Is it just the shape? They’re pretty light. Of course they’re much wider than a phone but not nearly as tall

Yes, just the shape. The current pumps (that I have seen) are like the race radios the pro riders use: they look very uncomfortable under the jersey.

I can see that. I just ordered the cycplus AS2 PRO. I don’t think it should bother me since I’ve carried my garmin inreach mini in the past and that’s never bothered me. But I can see how it could be annoying

I can finally speak to this one because I too was hovering on this and then said to heck with it last week and pulled the trigger. Read a recent review that spoke well of it and was recent enough that they paid an extra $55USD to get it because of the stupid. I managed to grab it without the orange idiot’s surcharge and it just arrived yesterday. Also managed to get it with the carry case without extra cost but it’s rather large (fits the pump and all the accessories) so I’ll probably use that for transport then pop it in a snack sized zip top bag for actual riding because it ain’t waterproof like any of these things. Fits perfectly in the front of my cervelo top tube bag. About an inch deep so a little thick but should be tolerable in a pocket.

As for performance I can say it works in the 2 tests I’ve done since I got it yesterday. I too have had issues in mind when I go out with a mini pump or Co2 and have no idea how much air I’m actually putting in for a repair. Always to firm but is it firm enough? or too firm? So this seemed ideal. And so far so good. I picked this over the new silca one because the silca cuts off arbitrarily at 72 psi and can fill 4 times for a difference of like 5 grams where this one has the gauge, has a settable cut off and it seems to be accurate. I think it has a similar battery life/number of uses but I feel like it technically could do more since I’ll only be filling into the 60s at most. I just did a test with my road tire having the pump set to 67 psi. Noisy little thing but I care not so long as it works, this thing is for emergencies. Didn’t take too long to get it up from 40 psi and shut right off when it hit the set point. Checked it against my topeak pressure gauge and it only lost 2 psi between me removing the pump and then putting on the pressure gauge so I’d guess it hit the target pretty much dead on. Likewise because of the screen you can also see the battery level when charging and it took maybe 10 minutes to get it up to full from the middling charge it arrived at.

So yes, should work, I’m pleased. It also has a light :man_shrugging:

It’s not, in my opinion. I bought one thinking it’d be better, but was disappointed in the inaccurate gauge. Got an AS2 Pro and it’s smaller, feels more solid, and is +/-1psi as advertised. Maybe the prestaflator will pump for longer, but that’s not my use case for one of these.

Does this charge with a USB-C or Micro USB cable?

The pump has to have an air inlet somewhere. Several brands use the USB-C port as the air intake. So there’s a direct path for water to contact the electrical circuits. If your pump came with a plastic bag to keep it dry, use it.

I’d say it’s faulty, but I don’t know at what level (design, bad batch of sensors?) They curiously don’t list an accuracy spec on the website, just that it’s ā€˜precise.’

An MTBR member tested multiple of the little pumps and found a similar offset that I’m seeing. I’ve exchanged a couple emails with Prestacycle, so we’ll see what happens but I’m not expecting much. I like their chucks and compressor inflator tool.

I haven’t seen any other reviews with real pressure tests, but I know Dave Rome is working a new roundup for Escape that I’m sure will have lots of data.
