The rider/bike model spinning in place, on its own — no map, no GPS, no camera-bearing tracking — so the model's own geometry and rotation is obvious at a glance, and nothing else can be the reason it looks wrong.
Runs TrailReplay's (github.com/alexalmansa/TrailReplay) own published follow-behind camera math verbatim — smoothBearing/smoothZoom/smoothPitch and the zoom/pitch anchor presets, straight from their source — driving RydR's real map, terrain, and bike model against one of your own saved rides. This is their algorithm, not a RydR reinterpretation, so it's a fair point of comparison for RydR's own chase-cam/ride-detail camera.
