The teams on this episode must travel over water on their water bikes. The teams will race their bikes up and down a 50 foot floating course in a relay race. One team member must travel down the course to a floating platform and pass the bike off to a teammate who will travel back down the course. They will repeat this until all 4 team members have ridden the bike and switched platforms. First to do this advances and wins new dog-tags.

The Scrapheap Henchmen are going for a design with three wheels at the rear with paddles attached. Their frame will be made of metal and use PVC pipe pontoons stuffed full of styrofoam for flotation. It could be tricky having 3 wheels at the back and the metal frame will make it heavy. If the wheels work, they will move much faster through the water with more pushing power.

For the Gearhead Gremlins, it's one smaller wheel with paddles. They will also use PVC pipe pontoons but they won't be filling theirs with anything but air. They'll stretch latex across the ends to make they waterproof. Hopefully, the pontoons will stay waterproof or they will sink like a stone. Another thing is that the one wheel won't provide as much push through the water as the other teams should.

The Reds earned a quick 3 bodgits	Blue also earned 3 bodgits
The Red design incorporates a small wheel. It's easy to build but not very powerful	The Blue team are building an ambitious three wheeled design. It should be fast but it'll take some time to build
The Blues use styrofoam to provide more flotation for their bike	Red cuts a piece of PVC pipe down to length
A fin goes onto the Red's bike	Both team has a frame that looks pretty much the same
The Blues are trying to figure out how to attach their chain	The Red's finally get their rear wheel on
The Blues have to weld the hub so all three wheels will turn at once	In the final few minutes, both teams attach all kinds of stuff to their bikes
The back-and-forth course	Blue immediately flips over! Because the driver sits too far back, it goes up and over
Red is also having a problem with a chain that keeps coming off	Red finally made it across and the return driver decides to peddle anyway, using this feet to move along
Blue finally makes it across and switches drivers	It was too little too late as Red gets their last team member to the other side, giving them the win
