Idk it might use magnetic brake pads. I have used them in other fields & they are pretty nifty. The ones I used created eddy currents & had not mechanical wear. For my project the mechanical brake had a ~10 year lifespan while the magnetic brake could last ~50 years. Also the mag brake was only 30% more expensive but didn’t need maintenance & would be significantly cheaper if you took the lifespan of the project.

Read with a real book if possible . If you sleep by yourself you can be quiet with just a small light. Either I get lost in the story then can sleep or it gets so boring sleep seems better then forcing myself to read another word.

Honestly great I got to bike till my legs were sore & saw an amazing sunset
