we didn't ask a few important questions. Did anyone help you adjust the saddle/seat hight with or for you? Are you comfortable with the reach to the bars? If the saddle/seat is too low your legs will tire out much faster than you might expect. Make sure to check the air in your tires. Until you get used to riding simply not pushing a bigger or harder gear than necessary will make life a lot easier. As far as climbing hills with a 22 small ring in the front and a 32 tooth cog in the back you should be able to climb a wall if you just take your time. You will be fine just keep at it.
