Derestricting bosch smart system

[davosaurusrex]

You first need to get permission from your bikes manufacturer(not all are willing to do so). Your local bike shop has to email a request to the bike manufacturer to do this procedure. If approved the manufacturer will email a file for the bike shop to download new firmware into the bike that shuts the internal speed sensor off, while also turning on one of the motors existing electrical outlets for the new swing arm speed sensor to plug into.
Then it’s about $50 in Bosch parts. (Bosch Speed Sensor, Bosch Speed Sensor Chain Stay Adaptor/Holder, and Bosch Spoke Magnet)

Which manufacture have you been successful with?

Hey guys,
looking to buy a bike with the bosch cx 4 Smart system and wanted to know how everyone is going with their unlock chips.

Currently Looks like the Volspeed seems to be the most reliable/least likely to occur detection? Has anyone come across any issues using it consistently at 40kmh + ?

Cheers,
