All our programs and apps currently are tested thoroughly with STEP8000 systems. Please do not use them with any other system!

motor firmware 4.5.1 – 4.7.1: you could use miniMax or eMaxMobileApp to switch to the US version to increase max. motor support speed (20mph / 32km/h) with correct values on the bike display

motor firmware 4.5.1 – 4.7.1: you could use miniMax or eMaxMobileApp to modify the wheel circumference to increase max. motor support speed (results in non – correct values for speed and distance on the bike display)

motor firmware 4.3.4 – 4.4.5: you could use eMax or eMaxMobileApp to modify the wheel circumference to increase max. motor support speed (results in non – correct values for speed and distance on the bike display)

motor firmware 4.2.7 – 4.3.2: you could use eMax or eMaxMobileApp to modify individually the Eco, Trail and Boost mode to increase max. motor support speed up to 60km/h with correct values on the bike display

Just have a look to this document on how to perform a motor firmware downgrade

Welcome to the new eMax website, which we finally have launched today;-)

The site is still preliminary and under construction!

In the next days we want to add a lot of new cool stuff and features (e.g. “Questions and Answers” – section, Blog, https, …).

Feel free to stroll around and leave a comment on info@eMax-Tuning.com.

Special thanks to Philipp S. for his great help and support!
