About this app

App works with Shimano E-Bike motors (EP801, EP8, EP6, E8000, E7000, E6100, E5000) via Bluetooth.
Allows:
- Get E-bike information (total distance, battery health and etc)
- Change assist settings
- Change gearing type (mechanical, electrical) and chainrings size
- Presets for quick setups of your bike
- Other features depending on bike's firmware

Warning: the new EP801 and EP6 motors do not support changing advance settings (region, circumference). All other motors with the latest firmware do not support changing advanced settings via Bluetooth.

Ratings and reviews

You need to have the old firmware, which they can send you the instructions on how to revert back through Bluetooth on your phone. Once I did that the software worked as advertised. Keep in mind the initial cost of the software is not the final amount. It's an additional $38 for unlocking all the features of the software, but it is worth it and it will truly derestrict your Shimano ebike. Unlike a piggyback, you actually get the full use of your mph on your display. Follow provided directions!

E035 error after following instructions and firmware update loaded onto bike successfully. Basic app works but premium involves loading an unverified apk file (Android) then adding .dat files within filesystem. Fiddly setup and ultimately didn't work. EP8 RS motor. --== update: thanks for the feedback. haven't had time to tinker with it - will update soon ==-- UPDATE: Finally got around to troubleshoot again. Emailed the developer of the app and resolved it. Quick response. Kudos.
