The power-to-weight ratio (P/W) is one of the most important metrics for cyclists. It shows how efficiently you convert your power into motion, especially when climbing. A good P/W value means more speed for the same power output – a crucial advantage in training, racing, or on your next ride.

The power-to-weight ratio (P/W) is calculated by dividing the power in watts by the total weight in kilograms – including rider, bicycle and equipment.
Power-to-weight ratio = Weight (kg) / Power (W)
Example:
A rider produces 250 watts and weighs 75 kg (including bicycle).
75 / 250 = 3.33 W/kg
This shows how much power is generated per kilogram of body weight.
Riding uphill – The higher your W/kg, the faster you can climb a hill .
Comparability – P/W allows for a fair comparison of drivers of different sizes and weights.
Training efficiency – Knowing your own worth allows you to work specifically on weaknesses.
Performance diagnostics – Perfect for FTP tests , training planning and competition preparation.
The interactive calculator makes it easy:
Enter power in watts (e.g. from a power meter or test).
Specify the total weight in kilograms (including bicycle).
Click "Calculate " – your W/kg will be displayed immediately.
The computer also roughly categorizes you into:
<2 W/kg: Beginner
2–3 W/kg: Advanced
3–4 W/kg: Amateur-Professional
>4 W/kg: Professional
This way you'll quickly get a feel for your performance level.

Performance improvement – interval training , strength training and longer rides increase wattage.
Weight management – Reduce unnecessary weight on your body or bike without compromising your health. Tip: The MYVELO Verona road bike weighs 6.9 kg (Dura Ace and Lightweight Tubular tires – without pedals and bottle cages).
Improve your riding technique – Efficient pedaling technique saves energy and improves effective performance.
The power-to-weight ratio is a key metric for every ambitious cyclist. With the power-to-weight calculator, you can instantly check and compare your current status and train accordingly. This way, you always know where you stand – whether you're on a road bike , gravel bike , mountain bike , or during hill training.

Almost every road cyclist remembers this moment: You're rolling slowly up to a traffic light, everything is relaxed – and then you simply tip over . Not quickly, not spectacularly, but agonizingly slowly.
Ein Tubeless-System funktioniert nur so gut wie die Dichtmilch, die darin zirkuliert. Sie dichtet kleine Einstiche in Sekundenschnelle ab – aber nur, wenn sie noch flüssig und wirksam ist. Wer sie vernachlässigt, riskiert, dass der Reifen bei der nächsten Panne nicht mehr selbst abdichtet oder schleichend Luft verliert. Die gute Nachricht: Dichtmilch nachfüllen oder wechseln ist einfacher als viele denken.
Die Tour de France 2026 ist entschieden: Tadej Pogačar fährt zum fünften Mal in Gelb nach Paris und schließt zu den Rekordsiegern auf. Das Finale über den Montmartre entschied Mathieu van der Poel um eine halbe Radlänge – gegen seinen eigenen Sprinter.
