  • Took a Peloton Bike apart for easy transport. About 20 minutes.
    I just bought a used Peloton Bike (Gen 2) so that I can have a separate one from my wife Fitting the entire bike in one piece would not have been possible with my station wagon, and it would have been too heavy to carry by myself anyways Instead, I took about 20 minutes to carefully take the bike apart (times are approximate):

    I'm at 225 runs and 160 tread Bootcamp on the app and got a shout-out for every milestone I did 275 rides on the app prior to getting the Peloton bike and got milestone shout-outs for all but one milestone I got strength shout-outs using the app too I thought the Echelon was a solid bike The Peloton pedals are a bit smoother
