I've lent out my spare bike (the Axiom) to a friend (for as long as several months at a time). In fact, this friend will be borrowing my bike this weekend perhaps as she prepares for a multi-day tour through Oregon in September. She'll be riding a drop-bar bike during that tour and she has only a flat-bar bike. She'd like to get her long training rides in on a drop bar bike.
If someone comes to the area (friend/family) that wants to go for a bike ride (and fits on this bike), they are welcome to use it. However, I don't think I'd rent it out to a stranger. If the bike walked, insurance money just wouldn't cover the true loss I'd feel. And I trust my friend with the bike.
