Meet The Zpider Power Meter

Our best model yet for road use is the ZPIDER. It comes as a complete crankset with the measurement unit integrated into the spider connecting the spindle to the chain rings. This is generally considered the best and most accurate way to make a bike power meter today. We agree.

It gives you fast updates, measures the total power from both legs and even calculates the left/right balance.



Yes, surely they are… we are from Denmark. The power sensors are very well protected which makes them not only water- but dust proof too.

Rechargeable and Green

The Zpider is equipped with integrated rechargeable batteries with light indicators on battery status. A single charge enables minimum 240 hours of riding.
