Thank you for taking them apart and showing the differences between the batteries and pumps on each model.

When you first started taking them apart, I thought the only difference was going to be the display and battery size. I'm glad you did as we could see that the motors and pumps were larger on the pro and pro max as well!

More gear I definitely don’t need!!! But now I want one. Love great bike stuff

As always in-depth, fun, detailed video,explaining all the ins and outs. I really appreciate how you even opened it up and show us the inside. you’re the real deal Mr. Oz.❤

I’ve watched a ton of these videos and this is by far the most helpful of them all.

Been using the cheapest model for several months and probably 2500 miles…Its the most used pump on the rides, great for topping off a tire that lost air during a slow to seal puncture on a tubeless, or for the occasional tubed rider flat. My only complaint was the lack of gauge, which is solved with the new pro models, which of course I already ordered. I also have the much larger Cyc plus pump about the size of a water bottle, and replaced the chuck with the excellent Silca one for ease of use. I use this in the garage to inflate my tires prior to rides since the bikes are wall mounted, and it goes a month without charging.

Yet another great informative video. Nice one Mr Oz. Think I’ll have me an AS2 Pro. 😎👍🏻

سلام. ویدئویی کامل و آموزنده و با جزئیات. متشکریم از شما.

Perfect solution for travelling by plane. Thanks for the in-depth review.

Thanks for the review. I ordered a Cycleplus pro 2 weeks ago. Hopefully I get it soon. As you stated great for plane trips.

Very excellent and THOROUGH! Thanks. Very helpful for those interested in purchasing an epump…whatever size!

Thank you, really appreciate the video. I bought a bit bigger/chunkier generic version that is generally used for car and motorcycle tires, and toiling with the idea of buying cycplus. Thanks again. ❤✌🏾

Excellent video! Thanks.

Thank you as always for a comprehensive review- I am a longtime viewer who switched to waxing after watching your videos and am so glad I did. Keep up the good work 👏👏👏👏

Thanks. Great review!

Great review. Firstly, I wasn't aware of the Ozito pump. I'll be getting one of those for sure. Currently, I carry 3 CO2 cannisters along with a mini pump. If I swap out the cannisters for the AS2 it looks like a great weight saving and AS2 is more effective . Thanks

Best review of these products I've seen. 🐐

good review Steven....

I will go with the AS2Pro, that looks like the perfect size for me, ps love your shirt 👍.

Very cool, convenient pump

Thanks for another great review! I've been thinking about getting one of these, but wasn't sure which model. AS2 Pro does it! Been a huge fan for a while and have seen gains from your advise on chain waxing and tube selection.

Excelente video como siempre, saludos desde España!

Definitely considering one of those. I run tubeless on all my bikes, usually fill up with CO2 when I get a puncture (which isn't recommended for the sealant). The wheels on my new bike explicitly forbid the use of CO2 so I'll be stuck with a handpump or need to get something like the cycplus.

Спасибо добрый друг. Продолжай. Твои видео я всегда смотрю в первую очередь!

Great review thanks

Great details 👌

excellent vídeo. thanks.

Nice informative review, thanks. Worth noting however that packing an unboxed inner tube tightly against tyre levers & a multitool could very likely cause them to rub a hole in the tube (as I discovered to my cost). I keep the tube in its box now

Interesting. Noisy AF though, I wish the shop version were properly insulated, I don't pump enough tyres to justify that noise instead of thirty seconds of pumping. Also, thank you for all the content you create. You're a direct influence on me switching to waxed chains years ago, I can't say my chains last longer nor can I say I save watts, but I love the cleanliness and I've been doing waaaay more bike maintenance and have become way more familiar with bike mechanics because of waxed drivetrains, just because they're not nasty to work with. I think that's the biggest gain at society level: understand your bike better, use it more, maintain it better. Thank you.

I’m glad to Cauchy this video as I’m contemplating for one, undecided. Not I’m motivated to buy. Thanks.

I have the cube but Im a multi discipline rider. I own 32c tires, and a 54c tires. I predict you will get slightly more battery cycles (device longevity) when using high volume low pressure tires. The poor thing just produces so much heat when trying to exceed 50 psi that I only use it in short bursts to try and manage the internal heat doin all that dumb entropy n shit and gettin ma battries all hot.

To expand the usefulness of the pump an adaptor for sleeping pads would make them ideal for bike touring.

I have a Fumpa pump. About the size of the Pro max but has a flex tube attached bent at 90* so it's all good to go without losing attachments.

I also weighed my 3x co2 cartridges with fill appliance and my trusty mini morph hand pump. 420 grams

I have lupus/SLE. I’m researching wheelchairs as I think I will probably need one in the not too distant future. Some wheelchair users perfer inflatable tires. I think the larger two units would be ideal.

Could you please test on several tires how much time it takes to pump for a certsin pressure with the smaller epump. And make a table with tire width, pressure, time. One can use tese data combined with machine learning (SVM) regression analysis to predict a required time for a given tire width and desired pressure. And as always - very informative video! Thank you.

seems like a good thing to have besides the handpump to make the last 10 psi easy of yours and your riding mates. 2x pumps from 0 until the battery goes out is kinda unrealiable as youll def. forget to charge it from time to time

I have the cube. It works hard to do what it does. Perhaps a little too hard. I doubt it will fill AS MANY tires as a traditional frame pump or non battery pump. But for now its better than jerking off my pump trailside.

Ози береги себя, не нагружай себя накачивая колесо :)

Ok now this is very interesting, and very cool ! I'm guessing they haven't hit shops yet ?

In Europe, you are allowed to take CO2 Cartridges on an aeroplane, in the cabin baggage. I did this several times. Are there other rules overseas?

Just bought one thank you for the video! Let's see what the lifespan is.

Which tpu tubes are you using ?

Nice review only thing missing is how the battery life is on these over a longer term. Can I charge this, leave it in my saddle bag for 6 months, then whip it out and pump my tire up? Or will it be dead and useless..

Wow, I was living in the stone age, didn't know these where a thing. Can the Pro version pop a tubeless back in place?

None of these mini pumps (including those intended for cars and motorcycles) have replaceable batteries such as 14500/18650, and the degeneration of battery will be an issue in the long term. I think another necessary feature is an "eco mode" which runs slower but is quieter and less hot.

Thanks for this very informative video. I think this device might be excellent for bikepacking. Plus, I'm not currently happy using CO2 cartridges because; a.) they put CO2 into the atmosphere; and, b.) once used they are gone if you get another flat. That said, I guess lithium batteries are bad for our environment, too. My question is, how much volume of air do you get out of a battery charge? I'm running 27.5" x 4" fat tyres. I would hope to get multiple re-inflations from a single charge.

AEG also has a similar pump .

You put out a video about TPU specifically noting TPU is safe to use a CO2 to inflate. Now you say it may freeze the TPU making it brittle and lose air. Do you have evidence / experience either way? Personally I've inflated 2 TPU's with co2 and they are still in the bike rolling fine.

I thought it would be cheaper... I guess I'll stick to co2 cartridges. At your conversion rate of 55 cartridges per pump, I'm good for another... 15-20 years ;)

Co2 cannot pump tpu tube? Thank u letting me know

want to buy

Going for a ride means charging: Wahoo - mobile phone -DI2 shifter - front light - back light - and now the pump that wa quietly sitting in my tool bag for a decade with no maintanance needed at all. And it is very loud. I like your vid - I do not like the noisy little compressors.

Pump has a ball bearing on the crank. Kind of impressed. Would have been cheaper just to use a bushing but the used a ball bearing.

I see you have a butyl tube in there,thought you were using tpu 👍

How many mah are the batteries on each unit?

What about tubless?, with CO2 I can inflate tubless from scratch. Mini pump I guess to slow, right?

I'm finding using the AS2 Pro _EXTREMELY_ frustrating. In order to use the hose I have to screw it on. The problem arises when it's time to unscrew the hose from the valve. When I unscrew the hose I inadvertently unscrew the valve core.

You can't seat a tubeless tire with it, can you?

Wouldn't be to hard to make a cylinder version having the motor on the bottom driving a piston up the tube be handy for using an existing mount on your bike! Just throw that out there see if anyone picks up on the idea

i think CO2 is more reliable and more simple. i did use CO2 for daily and for long trip, first thing i like use CO2 it pump fast, easy to get the cad ridge and it rather cheap and light weight also. it not get in trouble if soaked in wet.

Pro is $129 usd, I’ll just using my pump!:)

Are these pumps sold locally

Fumpa is the best

It's just a fad, one long ride in winter I had 3 punctures in one ride (Gp5000), manual pump never runs out and is reliable and trusted. (PS yes I removed glass each time i ride on awful shitty roads)

I have the small one. Just like my drone what I do not like is the noise it makes. I feel I'm disturbing nature and people around me....

Eh? I ride a bike but I’m too unfit to use a hand pump?

Did you know you have fans in England? Well you do now.

Half the battery discharged in 2min ... thats 30C discharge rate ... these batteries will be killed in 30 to 60 cycles and will need replacement. I guess they are soldert in?

The real test will be reliability.

The biggest critique I hear about these pumps is that they struggle at the really high psi's. I would have really like to see it pump to 100 psi or so. I'm still not sold without that high psi ability.

IMO not worth the risk of failure on a ride. I'll stick with human powered mini pump.

Electro garbage, combines the worst heavy+slow + longterm reliablitiy

Saddle bags run your thighs and your pants, very inconvenient

The noise is unbearable. ☹👎

yeah no mate, nice try on this junkie thing, won't do tubeless from scratch need compressor there, and of course the mini pump never goes flat, ... did I mention it never goes flat and mini pump less weight and space requirement. like an ebike good if you're lazy and weak I guess.

Electric mopeds otherwise known as chEat bikes, electric pumps is there no end to this laziness

FFS! I've got better things to do with half an hour for what can be said in 2 or 3 minutes.

Another disposable piece of plastic from chinese lasting a few months😊 they could at least add 12v input so at least ebikers could pump before the gasket would fail. Of course they won't. Otherwise it's just a toy, better to buy a box of co2 if you need it.

flat batteries for flat tires :D
