Concept2 BikeErg

Built like Concept2's rowing machines, with the same air flywheel and PM5 monitor, which suits riders who want hard intervals and numbers they can compare from one session to the next. A damper changes how heavy the pedaling feels, and resistance rises naturally the harder you push. The PM5 works with the free ErgData app and others such as Zwift, so there is no subscription to pay. It also takes standard bike parts, so you can fit your own saddle, handlebars and pedals, a real advantage for anyone who finds stock exercise bike saddles painful. The $1,100 price buys no screen and no classes. It sits on a 48 by 24 inch footprint, and Concept2 recommends a 60 by 48 inch area to use it.
