I have a total of 3 in my garage. I mainly keep them around for short trips here in there in case I need them. No gas/oil needed, pure muscle strength. Although you have to consider calories burned. You can attach a cart to them, be silent in bad areas and of course get your exercise needed. Just remember to have extra tubes, patches, co2 inflators or hand pumps. Depending on the situation, you might OR might not want to take the reflectors off.
