+1 to Triguy. I tried to do this once and found that to insurance companies, a bike is a toy. Unless there is some legal eagle or someone who doesn't have a life and wants to do the research and can state other wise, I think that Homeowners/rental is the way to go. A when you travel with it...make sure it's well locked and you can document that so if stolen your auto insurance may cover. Keep a hard copy of a picture of the bike (the one here isn't good enough as you cannot clearly see the components) and receipts for the build up or one from the shop stating the value. Insurance companies will do all they can to turn down your claim, unless it's well documented, because "It's just a bike." I've been through a replacement for theft from on top of my car and it's a pain. They paid, but it was nuts.

the key thing is to document the bike with serial numbers etc so that there is clear documentation of the value of what's being replaced under homeowners insurance (so they don't assume it's a 40# big box retail bike)

sometimes they'll add a rider for specific precious items that are specifically identified.

ask your folks about the policy for your household or call and ask yourself

it's worth protecting
i hate to see those posts that say someone's bike was taken

I think I'm just gonna do what everyone has been saying because i guess thats the only option (and not a bad one either).

It's a little funny how that's true! The law works in mysterious ways.

I am a claims rep for an insurance company. First thing you have to do is read your policy, because each one is different. There may be specific limits or exclusions that apply.

Speaking in generalities(see above), here are how bikes are typically covered. Bikes are considered personal property and are covered under your homeowners policy. They are protected from fire, theft etc. while in your home. But, what most people don't realize is that most HO policies cover personal property anywhere in the world. So, unless you are racing IM Venus, you have coverage.

To have the best coverage for a bike be sure you have the following two forms on your insurance policy.
1. Special Causes of Loss - it protects your property from everything but specifically excluded events. It provides the broadest coverage available.
2. Replacement Cost - when valuing damaged property, depreciation won't be factored in. An important coverage given how quickly bike values drop.

Examples:
1. You are hit by a vehicle while riding - Driver's liability should cover bike and medical bills. If they are uninsured, your HO policy on the bike.
2. You crash while riding - Unless crashing is a cause of loss excluded from the Special Causes of Loss form(which it typically isn't) it will be covered under your HO policy, subject to your deductible. Now they may make an argument about normal wear and tear exclusion. Stand your ground on that, when properly used, a bike shouldn't be skidding across the pavement. You could make the same argument for a MTB vs. a tree.
3. You run into a ped because they are rocking out with their iPod and not paying attention - Your HO policy liability will cover medical payments to them. Bikes, even if operated on the road, are not considered autos and your auto policy doesn't apply.
4. You are wrenching on the bike, it falls off the stand and the frame cracks - Covered under your HO policy, subject to deductible.
5. You forget to take the bike off your car rack when driving into your garage - Covered. Unfortunately for insurance companies, stupidity isn't excluded.

Some companies will try to take advantage of peoples' insurance ignorance. Be an informed consumer, read your policy. You would be surprised what could potentially be covered. And as someonoe else mentioned, keep a list of parts/equipment with serial numbers. If you can't give specific data when a loss occurs, an adjuster can't properly pay your claim.
