One thought on “Bicycle tracks

  1. Very confident — Thick track from rear wheel; thin track from front wheel
    Less confident — bike was ridden right to left
    (Neglected to indicate if bike was being pedaled forwards or backwards; though it doesn’t matter so long as you are a good enough rider to pedal a non-freewheeling bike backwards 🙂
