From scribble to public limited company – how a few bike sketches became a successful start-up
by Patrick Bardelli

Small, handy and easy to use without compromising on performance: bicycle pumps for on the go have to meet seemingly impossible requirements. Swiss start-up Daysaver’s rising to this challenge with its new Incredible pump. And it’s almost a complete success.
What started with frustration over mediocre bike tools ended up as a public limited company. In between was a Kickstarter campaign, which reached its funding target after three days. Since then, the start-up has continued to develop, and the multifunctional bike tools from Daysaver have become established on the market.
In the summer of 2024, I had the opportunity to visit Daniel Landolt and Peter Eisenegger from Daysaver on the Uetliberg and talk to them about their work. Here’s a rundown of my visit:
Back when I met with them, Daniel and Peter mentioned they were planning to launch a new, multifunctional bike pump at some point in the future. And the time’s come: the Incredible pump from Daysaver’s recently been launched on the market. The product comes in a large and a small version. I’ve already been able to try out the small one.

The Incredible pump is a high-volume pump, HV for short. These usually have a wide cylinder for quickly inflating large tyres at low pressure. In contrast, high pressure pumps, HP for short, have a narrow cylinder for high pressure in narrow tyres. To put it simply: HV’s for volume, HP for pressure. This means the model’s suitable for mountain and gravel bikes, but not for racing bikes.
When measured on my kitchen scales, the Incredible pump I tested weighs exactly 100 grammes including the hose. According to the manufacturer, its larger counterpart weighs 140 grammes without additional tools. Daysaver states the small pump manages up to 40 PSI or around 2.8 bar (the large one: 80 PSI/5.5 bar), and offers space for an additional tool from the brand, in my case the hose. The large model can house two tools.


The pump fits all Presta valves with and without a thread on the valve stem, which is at least 11 millimetres long. It doesn’t matter if your tyres have tubes or are tubeless. It’s supposed to be compatible with Clik Valves too. However, a corresponding adapter’s recommended. Schwalbe’s Clik Valves generally worked on my gravel bike, but when my hands were sweaty, it took a bit of fiddling somewhere in the forest until the adapter was screwed onto the hose. That’s not ideal. The Incredible pump isn’t compatible with Schrader valves.
But other new technologies are now coming onto the market. For instance, Dutch brand BBB Cycling recently unveiled its brand new valves. I reported on them. Unfortunately the pump doesn’t work with these new products from BBB.
You can attach this model directly to the Presto or Clik Valve without an additional hose. This works well in theory. But I’m always a bit afraid of shaking it too hard when pumping, and damaging the valve. That’s why my Daysaver motto is: always use a hose.

The small Incredible pump’s easy to carry in your trouser or jersey pocket, in a rucksack or, for example, in a saddle bag. Daysaver also sells a special bracket that’s attached to the frame. I stowed the pump in the frame bag.
In general, the product has a high-quality finish. The additional tool housed in the handle is secure, so there’s no annoying rattling. As I already mentioned, pumping couldn’t be simpler when you use the hose. But it goes without saying that it’s a lot more strenuous than with a floor pump. If I’ve counted correctly, it takes me around 50 pump strokes to put just under one bar into the tubeless tyre from Zleen.

In theory, there’s nothing wrong with this hand pump. The design is smart, and you can tell a lot of time and practical considerations went into developing it. It has a high-quality finish, and comes in two sizes with space for one or two additional tools.
And that’s not all – the Incredible pump’s compatible with standard Presta valves. No matter whether your bike has a tube or is tubeless. It also fits on Clik Valves. However – and here’s my only criticism – this proves to be a real hassle, at least with the Schwalbe product I tested, including the adapter on the hose. I’m deducting one star for that.
