New here, so sorry if this was discussed before or stupid in some other way.

While watching the show, I thought of the bike as a white person eccentricity, the rarity of which becomes a major plot point in solving the case. Just occurred to me that it may be more intentional than that. Tricycle, duh. It symbolises relationship between the three characters. None of them could do without the other two.
