• 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.

Derestricted Shimano and gearing?

Have yet to receive my new bike. Wanting to derestrict since i will be riding trails in the weekend AND commuting to work (tarmac/gravel/forest) almost every work day. Highest gear on the bike is 11 in the back and 32 front. The plan os to go with Sram NX Eagle and a 38 ring in front. This way it will keep a decent low gear (50back/38front) and a higher top gear (11back/38front)
NX Eagle will hopefully also provide a cheaper cassette and possibly stronger - read that it is the only Sram cassette officially emtb approved - might be wrong :)
The bike will be covering a lot of ground in all conditions year round even road salt in winter YIKES!!!
Any thoughts?
Thanks!

I think this will work. I upgraded my to a 36 up front and 'unlocked' it. I've hit 34 MPH with the 11 - 46 in the rear. But on average 30 is pretty easy.

This calculator will help you: Bicycle Bike Gear Ratio Speed and Cadence Calculator

You should be able to hit about 34 MPH or so.
