New Addition Avenue Recumbent Trike

I was gifted a recumbent trike yesterday. I already added a bell and phone mount. I am unable to get the pedals off and put on the SPD pedals. I guess I am just not strong enough. I will take it to a bike shop to get them off. The seat is quick release so it can get in my SUV easily. I went riding around the neighborhood for 50 minutes getting used to it today.
