FLEXTAIL Tiny Tyre Pump Pro ACS review – The perfect pump for your bike

REVIEW – Now that my entire family is fully into biking, we are often on the bike trails in the nature preserve not far from my home, and leaving home with an under-inflated tire is quite possible. Also, if we had to replace a tube while out riding, a conventional air pump would not work. Enter the FLEXTAIL Tiny Tyre Pump Pro ACS.

Design and features

The FLEXTAIL Tiny Tyre Pump Pro ACS is a compact and portable electric pump designed specifically for cyclists. It measures 77x53x32mm and weighs 4.59 oz. It has a 450mAh battery built in and uses something called AirVortech technology. According to the manufacturer, it can inflate a 700x25c tire from 0 to 80 PSI in just 50 seconds and can provide up to 120 PSI. The design includes a high-definition LED screen that displays real-time barometric pressure (switchable between PSI and BAR), adjustable units, and remaining battery life. As with most tire inflators, it automatically stops when the desired pressure is reached. There is a built-in USB-C port for charging.

Performance

The FLEXTAIL Tiny Tyre Pump Pro ACS weighs 110 grams and is 77x53x32mm. This small size and light weight make it extremely portable, whether you choose to carry it in your pocket, an accessory bag, or attach it to your bike.

My test results showed that the built-in 450mAh battery was able to pump up a 20×4” fat tire from almost totally deflated to the 27 PSI I wanted, and the battery indicator showed that there was still approximately 50% of the charge remaining. The manufacturer states inflation of a 700x25c tire from 0 to 80 PSI in as little as 50 seconds, with a maximum pressure of 120 PSI.

Once I unboxed the pump, it was easy to figure out how to use it, and I was pleasantly surprised that they included accessories for inflation, other gear like balls, etc. The built-in LED display shows pressure readings, and you can change to the desired type of measurement.

The device recharges quickly via USB-C and fully recharges in about 30 minutes. It can also be used as a taillight, if so desired.

Despite its tiny size, it is louder than I expected, and my other noteworthy negative is that a carrying case for the accessories is not included.

Overall, this is a fantastic addition for any biker, and since carrying it is insignificant, every biker should have one.

Final thoughts

The FLEXTAIL Tiny Tyre Pump Pro ACS is a great addition for any biker looking to ride without worry. It is capable of properly inflating any soft tire or any tube to full pressure.
