Yesterday my first off road trip with the 24F. Previous controllers on my Q76R/qs205: Adaptto Max-E and Sabvoton 72150. The NUC's are a major shift in high power e-bikes. All the setting you want in a small controller. The power is amazing/smooth/crazy, configurable from "baby mode" to "totally out of this world". 30% more battery/range and motor and controller just stay cool. Now that's a efficient controller! And believe me, we abuse our bikes big time. Look at the video where Vasily shorts the phase wires. All the toasted controllers have died a second time! If you have a + 4K watt e-bike: dump your controller and get a NUC. This thing has secret sauce inside. The russians did it again. Vasily=God Basta.
