I ride bikes as well - Was an avid 3-5 day a week rider for years prior to kiddos. I tried a trainer (still have it) attached to my Infinito roadbike but something about the saddle pressure of being stationary vs moving was/is very uncomfortable for my nether regions lol.
I opted for a kid trolley attached to my cross bike and I pull my littlest 1.8y/o along while riding with my oldest 8y/o but to your point, life has gotten very crowded, so is hard to get those consistent rides in like I used to. Luckily for me, I live where there is fantastic riding weather most of the year, so am not tied to indoors training like wetter places.
Still at it though and the pain relief from my back therapist + stretches + weight loss has been great
