iBike Gen III Operating Instructions Manual page 52

TIP: REMEMBER, THE EST CDA FUNCTION DOES A GREAT JOB OF PROVIDING AERO DRAG
DATA, WITHOUT THE REQUIREMENT OF A COAST DOWN!
Problem: I get the message "bad data" when I put the battery into the iBike
Possible cause:
1) Your iBike's ride file structure has been corrupted. Using your iBike software,
perform the command Device/Erase Ride Data. This will fix the problem.
