Finally an option to customise the gearing of your Bosch powered eBike.

As a general reference, if you increase sprocket size the cadence will become slower (harder to pedal / faster). By decreasing sprocket size the cadence will become higher (easier to pedal / lighter for hill climbing). Generally most eMTB's come as standard with 14-18t sprockets and road / trekking bikes come as standard with 16-20t.
