Yesterday I did the FTP (short) version, 276 W Yeah, but there where a few errors.
When you do the test, there are 10 different steps, first step is 5 minute warm up etc. But whenever the step started with more Watts to produce the motor of the trainer got very, very heavy. The resistance became so hard I couldn’t paddle anymore, even with lighter gears.
The workaround here was to hit the “E” key of the computer so the workout selection came up, and somehow the resistance wasn’t there anymore.
Of course it is very anoying to ride this way and I hope you have a fix for this. I looks like the program is sending to much resistance to the motor.
