Here you can find e-bike tuning tools for the popular Panasonic 36V mid-mounted engines (and for the new Panasonic New Generation motors). Fortunately, there are now a number of attractive tuning solutions for Panasonic e-bikes available: With the Sx2 Tuning Dongle, you can remove the 25 km/h limit of the motor assistance of your e-bike. Simply unplug the Sx2 dongle, and the maximum speed of your pedelec is limited to 25 km/h again. The Badass Box 4 for Panasonic 2020 motors is newer - this tool also has the advantage that the original condition of the bike can be restored very quickly. Another interesting tuning option for Panasonic GX0 and GX Ultimate is SpeedBox 1.0 or the new PearTune for GX0 and GX. New and innovative is the MBIQ-P plugin. If other tuning solutions for Panasonic pedelecs - which we have found to be good - appear on the market, we will also list them here. Larger chain rings for Panasonic drives are popular, too.
