Battery lights up in blue: battery has more than 82% charge - The battery has excess power due to the high voltage.
Battery lights up green: Battery has between 56% and 81% charge - your SUSHI still supports you with enough power to get through the city at a speed of up to 25 km/h. As long as your battery shows blue or green, all four or five (LCD display) bars are lit on your display at the top of the handlebar.
Battery lights up red: Battery has between 30% and 55% charge - In this range, the motor of your SUSHI BIKES only works with lower voltage and accordingly releases less power. Here you will already notice a subjective performance difference. You will still be supported enough to reach a speed of approx. 20 km/h!
How fast your battery changes between the individual charge states depends strongly on your driving style and external factors (gradient, load, outside temperature).
Likewise, the storage of your battery plays a big role, because lithium-ion batteries do not like permanent cold or heat.
