It's a dirty secret you're not supposed to know, but if you shower in the morning at work, and then ride home and get sweaty and shower again at the end of the day, you don't need to apply deodorant at work. You won't get smelly that fast. It's the second day after a shower that you start to offend. Just arrive at work early enough to allow some cool down time before you shower, so you're not still sweating when you step out of the shower.
You do need to bring a fresh towel, but you can manage with a pretty small one, almost a handtowel, or a large older one that is threadbare and light, to take off most of the water, then let your body air dry a bit before dressing, so you don't have to lug a really bulky towel to work.
