• 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 was looking around for a way to raise my cutoff without playing with software or plugging in an electronic device. I came across the speedi planetary gear setup which makes the magnet spin 1.5 times slower. Has anyone used one of these on a bosch setup. I have 2022 Trek Rail 7 for reference.

Thanks,

Craig

I'm also considering one of these, I'm trying to understand its effects on speed/distance and range whilst installed. Mileage corrections for example. Total miles ridden won't be the same. - Other than that, I'm sold!
