Why is bicycle insurance so expensive?

Bicycle insurance seems expensive compared to car insurance because the risk profile and repair costs are very different. For specialist comprehensive bicycle insurance that covers crash damage and theft, you pay about 8% to 12% of the bike's value per year, so a $10,000 bike costs $800-$1,200 per year to insure, while a $50,000 car might only cost $1,200 to insure, which is only 2.4% of its value. There are several reasons for this high percentage. First, bicycles, especially carbon road bikes, mountain bikes and e-bikes, are extremely vulnerable to damage. A simple low-speed fall can crack a carbon frame costing $5,000-$10,000 to replace, and damage to electronic groupsets like Shimano Di2 or SRAM AXS can cost $1,500-$3,000. Second, theft rates are very high in inner-city areas. Bicycles are easy to steal and hard to recover, with theft claim rates much higher than cars, especially for e-bikes left in public places. Third, bicycles have no registration or VIN tracking like cars, making fraud and repeat claims more common. Fourth, the market is small and specialised, so insurers have less scale. Finally, many policies offer new-for-old replacement with no depreciation and cover expensive accessories like carbon wheels, power meters and bike computers that can add thousands. If you only want theft cover, home contents insurance is much cheaper at $80-$200 extra per year, but it does not include crash damage, which is the most expensive part of bike insurance.
