• 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.

I am looking at a new bike to replace my existing scott e-genius. That uses a shimano motor. I have an app called st u locker that enables me to change the market from UK to US and raise the speed limit to 20mph. I find this to be just right.

The bike I am looking at uses yamaha pwx3 system is there a hack to do some thing similar on this? I see you can get a chip for full derestriction but would prefer to keep the 20mph limit. Is this possible. What are the options for this system?

Cheers Mike

Seems like there is not much of information out there yet for the PW-X3 on what is available and what is being advertised as available and whether or not it works without throwing error codes. :(
