Bosch EasyPump in review – Inflate your tires without the effort?

Modern ebikes offer the latest tech, so it makes sense for your workshop tools to be updated with the same features. With the EasyPump, Bosch introduce a compact electric pump to their range. Can it replace a classic track pump and does it have enough power to fit a tubeless tire?

Before we get into the review, we would like to tell you about our latest print edition.

According to Bosch, their compact EasyPump compressor isn’t only suitable for filling balloons and balls but can also reliably inflate car and bicycle tires up to a pressure of 10.3 bar. Available for € 69.99, various adapters are cleverly stowed in the specially designed handle. That includes a Presta valve adapter, a ball needle and a balloon attachment – everything you need for a post-ride party! Thanks to the USB connection, the EasyPump can also be charged on the go. The battery level can be checked via the LCD, which also shows the current and target pressure, providing a good overview. An LED work light can be activated via the keypad. The EasyPump allows you to set the desired target pressure, at which point it switches off automatically. The EasyPump has a claimed flow rate of 10 L/min and while this might sound like a lot, it is really very slow. It takes a whole 2 minutes for the Bosch EasyPump to inflate a typical 29″ tire to 1.8 bar. Even a standard floor pump is faster. Fortunately, the automatic shutdown frees you up to do other things while it reaches the desired pressure. You can already guess the answer to the question of whether you can fit a tubeless tire with the EasyPump. Seating a tubeless tire requires a rapid influx of air, meaning the cordless Bosch pump is reserved for adjusting the pressure or topping up air once the tire is fitted. The EasyPump allows you to fill around 8 tires on a full charge.

All the info you need
Thanks to the LCD display, you can always keep an eye on the pressure and battery level.

Almost all bikes now use Presta valves and a suitable adapter is included with the EasyPump. Unfortunately, it’s extremely inconvenient and cumbersome to use, since the adapter has to be screwed on to the valve. We never managed to get it to fit 100% tight or sit perfectly on the valve, which is just annoying! To ensure a good connection, it had to be screwed on firmly, but doing so caused a different problem altogether: applying too much force to the valve made the valve itself twist, breaking the seal of our tubeless setup and springing a leak.

Pump head with Presta valve adapter
It takes a lot of fiddling and still doesn’t seal – the screwable connection of the pump and Presta adapter causes a lot of trouble. Our tip: replace the standard adapter with a universal Silca valve adapter and it will work much better.
Not for fitting tubeless tires
It takes around 2 minutes for the EasyPump to inflate a 29″ tire to 1.8 bar, so there’s no chance it will get a tubeless tire seated.
Fits in every toolbox
The EasyPump is very compact and can be stowed in any toolbox or car.

Unscrewing the adapter didn’t always go as it should in our test either. If you’re not careful, you’ll end up unscrewing the valve core. Our tip: replace the standard valve adapter with a universal valve adapter from Silca for about € 35. With that taken care of, inflating bicycle tires works much better. Everything sits tight, it can be put on and taken off within seconds and you won’t lose any more air. By contrast, inflating the tires of our Transporter was relatively straightforward. No air escaped when we screwed the connection on or off. However, inflating a car tire takes a long time.

Tops

  • accurate pressure display
  • automatic shut-off when target pressure is reached
  • can be charged via USB

Flops

  • very slow inflation
  • not suitable for fitting tubeless tires
  • Presta valve adapter doesn't seal well

Conclusion

The compact Bosch EasyPump packages the latest technology in a compact design, but it’s far too slow to fit tubeless tires. What do you use it for then? For making slight adjustments to and checking the pressure. Unless you’re in a hurry, the EasyPump performs these tasks well with its precise pressure sensor and convenient display. However, its usefulness is limited. If you decide to buy one anyway, we recommend swapping the valve adapter and planning in enough time when inflating your tires.
