I checked my "hyperbike" spec that I posted (to crickets) back in 2015 and wireless brakes were not on the menu . For a safety system you need a mechanical system in addition to electrical. This is how the the Boeing stabilizers are designed.
I did spec ABS or ABA that is automatic brake application based on a central race telemetry system processing. I also had AST or autoshift - something that is just starting to unfold now (eg "new DI2")
The deal with my spec it it's tied to central race control - the rider just pedals and steers :)
====here's the spec ===================================
CCM : Command Center & Pit Crew Monitoring with full download/control capabilities
CRC : Cycle to Race Communications and Telemetry System
ORS: Optimal Race strategy processing, which includes Auto Shift Technology (AST) and Auto Brake Application (ABA)
Triple-A OS: Active Aerodynamics Attitude Operating System. Defined by the master race algorithm and on-board sensors, the ride attitude, height and saddle position of the bike is automatically adjusted to optimize aerodynamics and handling capabilities for the race course & current conditions.
CAD: Cockpit Automation Design, which includes motorized bar retraction, and rider information center with audible annunciation technology. Rider feedback alerts included under/over watts, inefficient aerodynamics over baseline, incorrect race course positioning, and pedal strike warning system. The main processing unit for CAD uses accelerometers, GPS, position, incline and other sensors throughout the bike.
TPMS: Tire pressure monitoring system feeds back to telemetry system and to rider CAD. Slip rates are also detected to warn the riding of a potential loss of traction.
VGS: In order to provide for optimal air flow around the rider without increasing drag, a Vortex Generation System is employed at the head, top, and down tubes of the bike, to create vortices and disorient air flow over the rider's legs, arms and torso.
EPSI: The advanced features of the Autograph are powered by the bike's onboard electro-pneumatic system - integrated. Pressurized before the ride, the onboard air supply is designed to be deployed throughout the race program. In the event of a low pressure, the rider's pedal stroke is can be diverted to restore air, or an optional electric onboard compressor invoked.
