Could you change out the handlebars on an electric bicycle like the one in this link to have cruiser style handlebars? If so, how much do you think it would cost to have it done in a bike shop, and how hard would it be to do myself? Also, if one day I wanted to move the motor and the motor driven wheel to another bicycle that's also 26 inches, would that be doable? Thanks so much!
