Bests & Worsts Reviews from Amazon

I'm not sure how to take this warning label. It says Prop 65, "cancer and reproductive" issues. I assume that it refers to the seat material. So, I will probably always wear pants while riding this bike. I have to thank California for requiring this label. (See accompanying image). As for the bike itself, it went together pretty easily. It rolls easily without folding as shown in the video. The operation is simple. I leave the monitor on "Scan" so it goes from pulse, to speed, distance, calories burned, etc. I like the adjustment for resistance. It's easy to change how hard it is to pedal. I like it but gave it four stars because of the label. I would like the distributor to reply here and explain the warning.
