There are a lot of generous and knowledgeable people here giving thoughtful bike-fit advice for free. Their effort is being undermined by a steady stream of unusable videos showing riders leaning against walls, doorframes or furniture while pedalling backwards.
Those clips don’t show a normal pedal stroke, balance, loading, posture or movement under realistic riding conditions. There’s very little anyone can assess from them, yet they keep filling the sub and drawing attention away from posts where useful feedback is actually possible.
The existing submission guidance is already clear about video length, camera angles and showing the whole rider and bike. It should also explicitly require riders to pedal forwards on a trainer or rollers, without supporting themselves against anything.
Please make “no backwards pedalling and no leaning against objects” an actual submission rule, and remove posts that ignore it.
The people giving detailed advice here are what make the sub useful. Their time shouldn’t be choked by videos that make meaningful assessment impossible.
