If you read the TF2 Forums on Steam, you've probably seen my idea already, but here it is for those who haven't.
The Tricycle of Astoundingly Nimble Knees (or T.A.N.K.) is an unlock for the Heavy I made up. It goes in his melee slot, and it deals the same damage as the fists, but swings even slower than the KGB.
However, when Secondary Fire is pressed, the Heavy hops onto his tricycle (1 second animation), the view switches to third person, and he now moves at Medic speed.
When Secondary Fire is pressed again, he hops off his tricycle (1 second animation), the view returns to first person, and he is now holding the tricycle like a weapon again.
While riding the T.A.N.K., if the Heavy receives at least 75 damage in one hit, he will fall off of the tricycle and immediately brandish it as a melee weapon. Airblasts affect him while riding, but do not knock him off the trike.
While riding, the Primary Fire will ring a bell on the handlebars, and sometimes the Heavy will say his line, "Run! I'm coming for you!"
If you run into an enemy with the T.A.N.K., the enemy will take 25 damage.
