I have an issue in general with scifi totally ignoring the existence of bicycles, but star trek is particularly fun to think about since in so many situations beaming down in an away team with electric mountain bicycles would be incredibly useful in a basic utilitarian sense. Like shuttles, bicycles could be treated as disposable if needed, you can always replicate more right?
You also don't need to build up any infrastructure on a planet for bicycles to function as transit system for huge amounts of people. A starship could arrive into a humanitarian aid situation, quickly adjust a bicycle blueprint for whatever bipedal humanoid lived on the planet, replicate a metric sh*&ton of alien bicycles and beam them down to the planet on mass. It wouldn't require longterm maintenance, lengthy training of local aliens on how to use, or return visits to resupply complex parts. A starship could drop bicycles, spare parts and maintenance gear and then leave and the citizens of that planet would be able to benefit from that for... decades? Even more? I am sure the instruction manuals would get super long with all the alien languages though....
Even if bicycles weren't being used as tools or transportation in a far future like star trek, there is no reason humans would stop wanting to bicycle recreationally or for exercise. Also you could go on crazy mountain biking rides on the holodeck right? I can't see how people wouldn't be doing that all the time along with skiing, surfing and other sports that are scary but exhilarating. Further, I think it is likely most bipedal aliens would have discovered bicycles at some point along the development into advanced technological civilizations. It would be really weird if only humans discovered them.
TNG in particular is egregious for not having bicycles since the NCC-1701 is so cavernous that unless you always used the turbolifts you probably are going to need a bicycle to get anywhere quickly...
What do yall think? Should star trek have more bicycles?
I imagine Riker rolling up to home on his bicycle. He swoops up to Troi on his danish commuter bicycle, and in a stupendously effortless fashion goes from bicycling to standing while barely shifting his body in a reverse Riker sit that draws your eyes into those sweet, high hips if only to admire their power and charisma (that is what you tell yourself). As Riker extends his kickstand with a supple cock of the foot he he looks at the camera, rings the bicycle bell and says "Daddy's home" with a smile.
