Well I'm going to have to count by "HOURS", as my 20 dollar, used Weslo "Pursuit 650" Resistance Cycle, didn't come with the "monitor". Thinking about trying to adapt one of the ultra-cheap "wire" bicycle computers some how. Still at least it's letting me spin and simulate hills, even figured out how to adpat some "metal half-clips" to the weird pedal's! For $20 bucks, 2 hours worth of disassemble, cleanout, regrease, reassemble, it let's me spin while looking out the window at the "ice rink" that are our streets!! With the Dec. temps having been below zero at night for many days, it's gona be a Looooooooooooooooooong time before my bicycle see's the road, RATS!
