Welcome to our SparkFamily and our team of CyclePaths...! :-)
Suggestion re: knees. Take your bike to a local bike shop and double-check that the bike is properly adjusted to your body. Saddle height and other variables can make a big difference to your joint comfort. Pick their brains at the LBS and see what they might suggest.
Another variable might be the terrain in which you cycle. Hills may be hammering your knees too much right now.
Most of all though, keep getting on the bike and loving it!
