• Warning!!

    Riding a tuned or deristricted EMTB is not a trivial offence and can have serious legal consequences. Also, many manufacturers can detect the use of a tuning device or deristricting method and may decline a repair under warranty if it was modified from the intended original specification. Deristricting EMTB's can also add increased loads for motors and batteries. Riding above the local law limit may reclassify the bike as a low-powered bike, requiring insurance, registration and a number plate.

    Be aware of your local country laws. Many laws prohibit use of modified EMTB's. It is your responsibility to check local laws. Ignoring it, has potential implications to trail access, and risk of prosecution in the event of an accident.

What software can I use to safely derestrict this shimano motor, I only want to change the speed assist limit from UK to US regional settings.

Also if I was to run into troubles and changed it back to UK to be sent off would this still void the warranty, TIA.

You can use the eMax - SOFT to speed up your EP801. I´ve done that too and quite happy with it.
Did you de-restrict with the app yourself or did you do a remote session? If you did the remote session how long did it take for Emax to scheduled your session, Meaning from sending him an email to getting your session? Thanks, Barry

I did the tuning via remote control session. The guys replied quite fast and I think the optimization including finding an appoinment which matched for me and them was done within 1 or 2 days after the first contact.

They did mine via a remote session today. Highly recommend them to anyone they were super helpful with instructions and the session was over in a few minuets.
