• 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.

For the purpose of tests.

Who has successfully de-restricted your Shimano RS motor with software or hardware (chip).

What are your thoughts?
And do you recommend the equipment/method used?

Equipment recommendations?

thanks

With STUnlocker you can change region to US (and lift the assist speed to 32kmh).
This is just a software mod.

You can also change the delivered power and if the wheel settings is altered too, you can lift the assist speed to 42kmh.
Some has noticed vibrations from the motor, when power was incrased - some has not.

If you take the bike to a Shimano motor dealer they can update the firmware to EP8(85nm), authorised by Shimano. I had this done on my Rise before delivery.
