Compared to a nice bike, they are still more expensive, but it’s not ridiculous for what you get. A bike with loads of torque, ample power, fully adjustable front and rear suspension and very low running costs. I also find the belt drive rather nice. Hardly any maintenance, just check the tension a few times a year.
Just use the washable ones, made from organic cotton. Lower environmental impact, shorter time until potty trained as well on average. Still not as good as not putting extra people on the planet though 😁
