A few decades ago, we held an annual party called "The Huffy Throw." It was the original, though bike tosses quickly became part of many mountain bike events around the country. Fat City Cycles sent up a crew each year and once brought a 500 lb bike named "Cap'n Crunch" they built from a diesel locomotive connecting rod and a bunch of saw mill blades. It had a steel cottered crank, and the bike was equipped with a special bracket to hold a Park crank arm straightener (HCS-1). Every time the bike fell over, it would bend the crank, and the HCS-1 would be pulled out to bend it back again. That arm was bent in and out quite a few times during the event and never failed.
