The accuracy of the cadence sensor (measures pedal revolutions per minute) is very important for our e-bike kits because a motor on the electric bike should start when you start to turn the pedals and turn off when you stop, helping you ride where you really need to. So from the very beginning, we decided to develop our own sensor. We'll tell you about how the sensor works and what technologies we've used in a separate post later.

In version 0.35 we created a case for the sensor (we will print cases on a 3d printer) and tried a new PCB board that was produced in Gdansk. Cadence sensor dimensions - 6.47 cm х 2.82 cm х 1.11 cm

It’s very important for us to make the sensor rechargeable so the sensor can be used without changing the batteries for several years if used correctly. Also when traveling it is good to be able to recharge the sensor, rather than trying to find in the mountains or in a small village a shop with a coin battery. That’s why we added a micro USB connector to charge the sensor. If necessary, the battery can be replaced in any phone repair workshop.

In the next version, we will add firmware for the sensor and the ability to update it via Bluetooth. And then we should ride at least 500 km (mostly in Krakow and the Tatras) to make sure that the new sensor is stable and responsive.
