What is the price per piece for Street Bike?

Is LEGO Street Bike a good investment?
Street Bike currently trades 183.6% above its $50 retail price, and it is retired, so no new supply is entering the market. Past performance is not a prediction — condition, packaging and how long you hold all affect what a set actually sells for. BrickStats reports the numbers rather than giving investment advice.
Why is LEGO Street Bike so expensive?
Street Bike was released in 2005 and has since retired. Once LEGO stops producing a set, the only supply is what is already in circulation, so sealed copies in good condition compete for a shrinking pool of stock. That scarcity, not the parts, is what moves the price.
