A new bicycle

I intended to buy a new electric bike for my wife but she insisted on buying a bicycle. Finally I bought a new bicycle for her. It looked beautiful and strong. It took me two hours' time to assemble it because it was broken into pieces when sent it arrived. When I finished assembling it, she rode it back home, whereas I rode an the electric bike. She felt tired after about twenty minutes' riding because she had been lacking exercises for a long time (was unfit/hadn't done any exercise for a while). We exchanged swapped, and I was also felt tired soon because I was also unfit, for I lacked exercises too. I thought my wife's decision was right because we both needed exercises.
