When using a Wahoo Elemnt, Bolt, or Roam and selecting a route to ride in Indoor Mode, Neo does not provide any resistance in response to gradient changes along the route.
You have selected your Neo as an ANT+ FE-C controllable trainer in the Wahoo cycling computer and have loaded a route from one of your connected apps (Strava, RideWithGPS, etc). When you begin pedaling, you can see progress in the route as your location indicator changes in map view, and your marker moves along the gradient in that view. However, Neo seems to make no resistance in response to the changes in gradient, and even level surfaces offer no resistance. The sensation feels like riding on a sheet of ice, with the pedals moving freely with even a small amount of force.
This issue was first reported by Stephen Tait on September 11. We escalated to Tacx on September 12th, 2019. Tacx acknowledged the issue on September 13th, 2019 and are currently investigating.
All other modes will work with your Wahoo cycling computer to control Neo, including workouts that you’ve loaded for erg mode from Training Peaks, etc. The only mode affected by this issue is Route mode.
Tacx have confirmed that Neo has received ANT+ FE-C certification, so the root cause of this issue is currently unknown. We confirmed that the issue appears to affect Tacx Neo, Neo 2, and Neo 2T.
For riding outdoor routes on your Neo, Garmin head units do work as anticipated.
Special thanks to Stephen Tait for discovering this issue.
