New outfits like
PowerMeterCity or
CleverTraining that specialize in gadgetry and indoor training equipment seem to be an emerging market. Power meter's are getting cheaper and cheaper, and are MUCH more accessible than ever, as are Smart trainers/Smart bikes and things like Zwift/e-sports etc. that are still more closely aligned with the traditional road cyclist sensibility, vs Peloton, Soulcycle products etc. The pros are starting to race on Zwift now.
Scoff if you will the roads outside aren't getting any safer and I think these areas will continue to grow.
