Unless one of your outlets is wired backwards, plugging this into 2 outlets on the same side of your electrical panel won’t do anything.
If you were able to plug it into outlets on different sides of your panel, then you just created a 240v short and the cable is going to be real-spicy real-quick.
For me, actual travel is 35 miles every day. Uphill elevation change over that distance is 800ft-1500ft depending on the direction.
Most places in the US never considered biking as a valid travel method when being designed.
