Probably not - compared with the general population there aren't many people who ride bikes, let alone extremely expensive ones. Bikes are relatively small purchases compared with something like a home or car or other types of loans, so even with high rates the interest would be very small. It would be nice for the buyer, but hard to imagine making significant money as the lender...

If somebody really wants a nice bike, just work on saving. Avoid eating out one extra time per week, make lunch, stop buying expensive clothes for a couple months... whatever, there are ways to save for a bike.
