Smallest portable electric bike pump ever! Check out the CYCPLUS CUBE

Even if it works, which it probably will, I have to say a solid NO to any more battery powered biking devices. You can throw a CO2 cartridge in your bike pouch for 20-30 years and you will likely never need to worry if it will get you out of a jam. However, with electronics, you likely will have to worry about batteries holding a charge (or ceramic capacitors failing over time...especially in a high vibration environment). I always take a manual pump and a couple CO2 cartridges on the trail. The manual pump it my PRIMARY source of air pressure because it will almost never fail when asked. However, I will always attempt the CO2 before the manual pump to save some time. I once had to (essentially) carry my bike 20 miles due to a lack of redundancy. Even if you choose batteries or CO2, I'd always suggest carrying a manual pump as well. I'd say redundancy is key...especially if you you ride alone. I don't like to rely on anybody else, so I go with what will almost be guaranteed to work over a long period of time...then I keep two of them.

If you run tubeless tires, it's an absolute must to carry CO2 because try reseating a tire out on the trail with anything else. I always carry a 2-3 cartridges and a manual pump. Could see carrying this in addition but can't really see it substituting for anything I already carry.

As I am planning for Ragbrai, this review is perfect timing. As I can not fly with my CO2 cartridge I was thinking of checking out this pump...but only 4 - 5 pumps will be a deal breaker. As mentioned in another comment...less tech could be the goal.

Does it work on motorcycles tire?

3:33 One minute twenty two seconds is NOT hundred and twenty seconds.

[@stevenr5149]

Useful if you like triangulating your pressure bit by bit.

[@grinwormjr]

a better alternative to those who go all over the world to ride, it would be allowed on planes which co2 cartridge are banned

[@kennibal666]

That is not 120s..... that is 80/90s...

Electric pumps do well up till 25psi, then there almost useless. I have a mini pump that less expensive and does the same.

[@aliancemd]

I have the Xiaomi pump, goes very fast to 120psi(under 1min), when I want to seat a tire. It’s not as tiny though but it’s very fast - I was able to get a tubeless tire on the rim just with that pump and soap on the wheel.

[@mtbboy1993]

Fumpa can do 60 PSI no problem. For home use I use Makita DMP18. I've not tried higher pressures. as 40-60 is usually what's needed to seat a mtb tyre.

[@mtbboy1993]

This is useless, Fumpa is in another league. I won't be surprised if this product flops on the market. How can they compete when there's a superior product out on the market already.
