Cycplus Mini Bicycle Tire Inflator

There are now many mini pumps that are lightweight and portable. One of the first pumps that I know of is the Xiaomi Portable Pump, but it is super noisy, rather heavy and also relatively bulky. Not ideal for bringing on bicycle rides.

In order to reduce the size of the pump, something has to be compromised. In this case, the battery capacity is greatly reduced to lower the weight, cost and size. For a portable bicycle pump that you will only use in emergencies, this is fine.

Cycplus Mini Bicycle Tire Inflator!

The battery capacity is only 300 mAh which is really small. This means that it can only pump 2 bicycle tires, which I assume is 2 road bike tires from flat.

Comes with a user manual and USB cable, along with a translucent rubber sleeve for the pump.

Clear instructions provided!

Shows the pumping capacity for different bicycle tires. If using on a large MTB tire, it might be barely enough for one tire.

Compact unit with the pump nozzle

I think the reason for this instruction is to ensure that attaching the pump to a half-inflated tire does not cause it to deflate fully when the nozzle is engaged to the valve.

Comes with interchangeable parts at the nozzle, if you wish to use it on Schrader valves.

With the nozzle parts removed

Cycplus pump weighs 98 grams! Lighter than I expected.

With the rubber sleeve, it weighs 116 grams

A CO2 canister with valve would weigh 83 grams, about 30 grams lighter.

A traditional manual hand pump would weigh 100 grams, including the mounting bracket.

In terms of weight, all 3 options are quite similar. Using the manual hand pump as a baseline,

Manual pump: Can be used as many times as you need. However, takes longer and needs effort.

CO2 canister: Can be used only once. Fast and quite effortless to use. Slightly lighter.

Battery powered portable pump: Can be used a couple of times. Not very fast, but saves effort. Slightly heavier.

Size comparison of CO2 canister vs the Cycplus portable pump. Slightly wider, but similar in thickness and length.

Here is how it will be used! Might not fit on smaller wheels where the spokes may block access.

Using the Specialized Aethos bike as a reference for the size of the Cycplus pump.

Here are all the spares and tools on the Aethos road bike!

All of them fit into the tool bottle, including the Cycplus portable pump.

I'm happy with the size of the Cycplus portable pump, as it is compact enough to fit into the tool bottle, replacing the CO2 canister. As an emergency pump, I hope I never have to use it. 

I recommend getting a mini pump such as this if you want to avoid putting a manual pump on your bike, and yet want to avoid using CO2 canisters.
