Is LEGO Muscle Slammer Bike a good investment?
Muscle Slammer Bike currently trades 349.5% above its $10 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 Muscle Slammer Bike so expensive?
Muscle Slammer 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.
