Actual Firmware

The connection with the bike is fast and stable. We can mess around with many option and seting.
I have an Ep801 with 4.4FW do you think at some point you will be abble to add the restriction option for the latest FW.
Good job anyways.

Очень функционально для систем Shimano

Много информации о батареи (кол-во циклов зарядки, здоровье), а также информация в каких режимах сколько пройдено, настройки мощности ассистента и тп.

С дополнительными манипуляциями можно сменить регион, тем самым повысив ограничение с 25 км/ч до 32 км/ч (за этой инфой пишите по почте в приложении, разработчики все подскажут)

Рекомендую!
