The Formula Cura-E brake is intended for e-bike applications. Formula determined that e-bikes require a comparable amount of braking power to downhill bikes given their higher speeds and longer durations of drag. The Cura-E is unique in that it features a sensor which sends an input to the motor, cutting power off during braking to help prevent a conflict between the two. The brakes use the same pad material as is used in Formula's downhill brakes. Sam Blenkinsop used the Cura (not the e-bike version but the regular Cura) at Mont-Sainte-Anne and will use them again in Val di Sole and Andorra, which is a testament to how well they work, especially given their low price point.
