Realistically though what is actually useful in a bike/ebike dashboard?
Accessory devices
Dashcam
lighting control
Heated grip control
USB power outlet control
Rearview camera, mirrors, panoramic vision display
Navigation
Compass
maps like Google maps, fatmap, waze, gps
Weather
Weather outlook display (with aqi too maybe)?
Barometer
Thermometer
System
Electrical like power consumption, remaining battery or range, amps being drawn, volts available
Tire pressure sensors
Would be neat to have switches to change the max power it draws probably by modulating voltage, e.g. 250W baby/euro mode, 750W US bike lane, public street mode, >1 kW offroad/private property mode.
How much power it can be generating by going downhill or drawing from solar.
Pacing
Clock,
pace meter
Speedometer
Physical sensors
dynamometer
G-force, accelerometer tracking
Inclinometer
Countermeasures
Radar detector
Radar detector detector detector
Smoke/chaff/flares/oil slick/caltrops/cash (so people run in the street after it) deployment
EW jamming to try to stop that drone or loitering munition from killing you
Did I miss anything?
