I got my Bushido Smart yesterday to replace my Tacx Flow, and all is going smooth.
As mentioned above I used the middle setting for a 700c wheel/tyre.
I used the iphone app to upgrade the firmware to the latest version, and calibrated the turbo a few times (adjust the wheel pressure until the calibration result is in the middle of the graph).
Then I fired up Zwift and got on with a workout. The workout automatically varies the resistance to the correct wattage, and seems to work fine - no more need to shift gears. The main issue is that I had to lower my FTP by 20W (seems the Bushido has a more accurate power output than the Flow, my previous one must have been optimistic).
When the workout finished it switched back to normal zwift, and the resistance was automatically controlled to simulate hills and descents. Feels completely different to the previous experience of no variation, much more like cycling outdoors and need to shift the gears accordingly. I need to decide whether this is a good thing, but definitely feels much more ‘real’.
So all good so far, all working as expected.
Bonus is the unit is significantly quieter than the Tacx Flow. Wasn’t expecting that.
