The Stroke Counter would be a belt that ties around the chest of a swimmer with two sensors on each side underneathe the armpit. The sensor then would count the number of stokes the swimmer was taking. It would count each time the shoulder would rub up against the sensor. It would work in every stroke. The benefit would be that swimmers could now see how many strokes they're taking each length. The goal would be to see how many strokes you're taking per length and then try to cut that...

I have some ideas on sports sunglasses, made specifically for the adventure racers. They would be used by rock climbers, eco-challengers, obstacle coursers, etc. They are somewhat like goggles, except without the tight feeling around the head. The tightness could be adjusted just before entering any water. The lenses have a UV protection agent to them. Draw-back - wear and tear. Due to the type of sport done, the sun glasses may not make but one trip, but then what sunglasses make...

The fact is everyone who plays basketball dreams of dunking a ball. The shoe compromises of a special force triggered spring mechanism which contracts right after activation. How do you activate it? When we jump, the force we apply towards the ground is much harder than when we are running or moving about. If you look at MJ when he takes off, he literally slams his foot into the ground, that force downwards allows him to go upwards. So when you slam your foot onto the ground,...

"No rollerblades in store". But what if you could quickly slip a walking pad onto the wheels of your rollerblades, and negotiate any store, stairs, gravel, etc. Borrowing the design from the skate guards used forever on ice skates, this could save the need for slinging shoes over your shoulder, not to mention a lot of time. The design of "Wheelwalkers" would have to have an angled base so that you could still manage the walking motion in the boot shell of the blades.

Wouldn't it be amazing if you could easily pack away your dartboard? Well what if all you had to do was blow it up each time you wanted to play?

A skateboard with suspensions (similar to a full-suspension mountainbike).

A portable device to carry in a golf bag which can slowly shred up a golf club or ball to the accompanying sound of screams. Uses: self-evident to anyone who has played golf.

Based on the idea of the "detachable faceplate" for car stereos, this bicycle frame lock about 2 1/2 inches long, is actually a small but critical part of the bike's frame. It has a 5-number combination lock. Without it securely fastened, the bike frame essentially has a "hole" in it and will collapse when someone sits on it. Made of steel or titanium, this tubular lock is highly portable and can be taken anywhere. In combination with a strong, standard bike lock, it will thwart any...

Motorised skate boards have been around for a while. Basically they are snowboard sized skateboards with 40ish cc engines on the back of them, usually chain or belt driven the back wheels. This is fine, but these monsters can't really be used on or at a skate park. Because of the size and the weight of them, it is impossible to do tricks with them. What i am thinking about is a motor that is attached to the back of an ordinary skateboard, but it is detachable. So once you get to the...

A special treadmill to either learn skateboard basics or enhance one's current skills: Treadmill with a rotating, flat surface and handles to grab on either side to keep one stable in the beginning. The surface could be tilted in any direction for a variety of slope experiences. The speed could be adjusted. For real beginners, you could even have grooves in the surface to help stabilize while one gets the basic feeling of riding. An advanced setting might consist of the treadmill on a...
