Kept meaning to post a picture of my $10 exercise bike up here. It’s called the Slenderline. It’s the perfect size for my tiny study, and I can ride it and observe Matilda the prospective race horse, Uni the white unicorn-esque ponything and Buns the black rabbit. Most new exercise bikes have electronics with which you can program in resistance, but not the Slenderline. It has a big screw that you turn, which lowers a bit of black rubber on to the wheel, making it harder to pedal. For someone that drives a Humber, this is startlingly advanced.
