Tiny Bike Pump, AS2, 97g, Aluminum Alloy Shell, No Pressure Gauge | Mini Electric Bicycle Pump, 100PSI, Fast inflation, Presta and Schrader Valve, for E-Bike, MTB, and Road Bike

Only used once in anger and at that time worked great, Have now received the AS2 PRO from CYCPLUS, Great customer service, Great bit of kit pump is really strong and battery life seems very good although not had to it would easily cope with 2 flats on a single charge another great feature is the digital display and the ability to adjust the pressure to your own preference. Well done CYCPLUS.

Good piece of kit that fits well in cycle bag or vest. First cycle out with it and got a puncture. Took me a while to work out why it wouldn’t inflate but then realised I had small gold valve in place and needed to take it out. Tyre blew up quickly and with good pressure to get me home with confidence 👌

I had some charging problems with the unit but I've had good support since and this is being resolved. I've had the opportunity to use it twice in anger and it really is a big improvement on a mini pump. It doesn't seem to get that hot in practice so I've removed the silicone case. This usefully reduces its size but I'll report back if I have cause to regret the decision. ------ Neat , if somewhat chunky, package that fits nicely in your back pocket. The flush valve socket means there are no protrusions. It's good quality and easy to use although the click on, double click start is a bit odd and the button could be more positive in use. Do note the requirement to pre-start it if there's already air in the tyre since it can't start against a back-pressure. I've tested 3 decent inflations in a row on a 28mm road tyre before it died. It's pretty quick too - maybe a minute or so. It will be my preferred option over gas canisters and mini pump. I can't see the justification for the price and expect it will come down. As an addendum, the problem with TPU tubes is definitely a thing. I One of mine has sprung a leak around the valve after pumping (I was waned!). But I have also had two instances of it not being charged properly after many hours plugged in. I'm check ing foe advice on this.

There's no denying that these are noisy and get warm when you use them, however they're incredible when you're miles into a ride and get a puncture, you'll quickly become the favorite member of the group ride once this comes out, just make sure you leave some charge for yourself! I rarely charge mine, yet anytime I've needed to use it there's always been enough charge to get the job done, really simple to use and takes up less space than I expected in my saddle bag, even nicely fits in a jersey pocket if you wanted. Would buy again without a thought, regardless of the price it's that good.

Was great untill after 18 months it just stopped working

Love this bit of kit! Works really well, charges quickly too and was able to inflate twice during two unlucky punctures in our cycling group. Unbelievably tiny, so easy to carry. No display for PSI & short battery life are my only gripes, but would be impossible to squeeze in soo much in such a tiny package.

A small, lightweight pump that performs as described, great for topping up tyres en route, or for rapidly inflating tyres following a flat; the pump also warms cold hands after inflating... A great substitute for icy, single-use cylinders...

This does what I need it to do, i.e. gets air quickly into the tyre without me having to expend a lot of swearing at a mini pump. I run tubeless (30mm c60psi) and sometimes the valves can get clogged with a wee bit of sealant. This can be a pain with a mini pump, but this blasts through it with no issue. In the field it works well. Shortly after buying it I had a big puncture on a ride. Popped in a Dynaplug, gave the tyre a quick blast with this and I was on my way in 2 minutes. Closest to an F1 stop you're going to get on a bike. BUT - and this is a pain - it's not just something I can leave in my top tube bag until I need it, as the battery drains disappointingly quickly when not in use. I've just been away for 2 weeks and the thing was totally dead today. It does fully charge quickly, but a star off for this annoyance. Just remember to keep it topped up and you should be ok though.

Jak na początek wszystko działa dobrze.

Good instructions comes with it. Easy to use and very powerful. Love it

There were some comments from people about the pump not working, failing to charge or failing to inflate a tire so I tried it out when I received it. Charged it up, let the air out of a bike tire and inflated it as if I was replacing a flat beside the road. Worked perfect and very easy to use. Recharged the pump and tried again on another tire (first one was a 26 x 2 and the other a 700c x 40) and worked fine again. Very pleased so far. I bought the one without a gauge since it is less expensive and I am just looking for an emergency repair. I don't need to reach a perfect inflation just enough air to get me home. I will still use my floor pump to inflate tires at home before riding. I don't mind CO2 (which is what I have carried for the past 15+ years) but if you only carry one cartridge and screw up on the first try you are out of luck and I don't want to carry a handful of cartridges so the mini electric pump seemed like a good alternative. I realize if the pump fails you will also be out of luck. I figure a cell phone and Uber are a good last resort. The pump weighs slightly more than one cartridge and an inflator head (about 4 oz). Since I could probably lose 20 pounds don't think a few grams either way matters. Honestly, I haven't had to fix a flat in like 4 years and I actually hope to never have to use this pump but it seems like a decent insurance policy for a small price.

Neat and easy to handle. NOICY!!!
