Problem
My console only lets me choose 1-9
resistance levels when I was told there
are 16 resistance levels on this bike
32
Solution
Random, Slope, Peak, Challenge, and Interval programs all use
1-9 difficulty levels as opposed to resistance levels.This is because the
program has a predetermined profile. In order to maintain this profile
a range of resistance levels needed to be assigned to a smaller amount
of difficult levels (1-9). So for example when you change the difficulty
level from 8 to 9 the resistance level range changes from 8-15 to 9-16.
This allows the lowest point in the profile to be at resistance level 9 and
the highest point in the program profile to be at resistance level 16.
The manual workout program uses 1-16 resistance levels as opposed
to difficulty levels. This is because there is no predetermined profile.
The program is designed to put the user in complete control of the
actual resistance.
