About this project
KoldRush keeps cyclists cool and comfortable while riding in the heat.
Exercise physiologist Scott Powers invented KoldRush in response to his own experience of overheating while training and racing his road bike. As an avid cyclist he was familiar with how overheating can hurt performance and often causing some riders to drop out of a race. Like other cyclists, Scott tried to prevent overheating by pouring water on his head during and after a hot training ride or race.
Scott heard about one team's creative attempt to stay cool. They brought an ice chest of cold iceberg lettuce and placed the leaves under their helmets to stay cool during the race. While it worked for a few minutes, the lettuce quickly became warm. Scott realized that many other cyclists wanted an easy way to stay cool.
What if a cyclist could simply press a button to deliver a cold rush of water to their head instantly while riding?
Scott spent the next two years developing KoldRush. He went through several prototypes and gathered feedback from other cyclists to create the product he is ready to launch this summer. Koldrush is based on the evaporative cooling effect, where athletes naturally produce sweat in order to keep cool. This effect is dependent on several factors such as humidity, wind, and the hydration of the rider.
For the first KoldRush prototype (shown below), Scott modified an insulated water bottle by attaching a powerful micro water pump, vinyl tubing, quick connect water port, and a battery pack. Scott could simply press a button on his handlebars to activate a pump that would send cold water from the reservoir, up through a length of insulated tubing and spray cold water inside his helmet onto his head. It worked beautifully to keep his head cool and keep him from overheating.
The problem was that there was no convenient place for the battery pack, and the wiring quickly weakened due to screwing on the lid to the water bottle. So Scott asked electrical engineer Denver Kimberlin to join his team to help create a wireless remote control so he could activate the cold spray from a button mounted to the handlebars.
When mechanical engineer Mike Farney joined the team, they designed and built a custom 36-ounce water reservoir (shown below and in the above video), to fit securely beneath the bike seat. They improved upon the original design by mounting the water connector and wiring onto the water reservoir, rather than on the lid. The team finalized the design of the wireless remote control to operate the water pump inside the reservoir. Following two years of testing the system, they discovered it takes only a small amount of cold water sprayed evenly on the head to make a huge difference in comfort for the rider and to help prevent overheating. The team then created a propriety helmet insert that delivers a pre-determined amount of water with each press of the button. They made sure it would fit easily inside any adult-size bike helmet and stay securely in place with Velcro.
THE FINAL DESIGN
The team completed the KoldRush reservoir design when engineer Charlie Wagner joined them. Charlie has 25 years of experience with blow molding and plastic injection molding. The battery pack is now contained within the reservoir, which was reduced to a more aerodynamic, smaller 24-ounce size and sits securely beneath the bicycle seat where a tool bag normally fits. The reservoir is also encased in a black, insulated cover too keep the water cold during long bike rides. A microfiber headband designed to channel water away from the rider's eyes is also included. Based on feedback of other riders, the team added a built-in tool compartment for convenience, and a quick-release hose connection for safety in case of a bike crash. The wireless remote now attaches to the handlebars easily and securely with Velcro. After two years of perfecting prototypes, KoldRush is ready for manufacturing in time for this summer.

WHAT WILL WE DO WITH THE FUNDING?
The KoldRush team will use the funding raised from Kickstarter to make this revolutionary product available for summer 2014. The funding will cover:
1. Cost of the tooling needed to manufacture and create the blow mold for the water reservoir.
2. Plastic injection molding for seat post attachment.
3. To manufacture the insulated cover.
4. To purchase the electronic components.
THE KOLDRUSH TEAM
Scott Powers. Inventor of KoldRush. Scott earned his Masters Degree in Exercise Physiology from the University of Arkansas. He has been and avid cyclist since the age of ten. He directed three medically-based fitness centers and was awarded the Governors Award for Best Health Program in the state of Arkansas by then governor Bill Clinton. In addition, Scott invented and launched a sports product called StretchRite and was awarded two patents. For 6 years he set up distributors in the medical and sports markets and was an official sponsor of the United States Association of Track and Field (USATF). He created Stretch Appeal, a stretching video program for women using his invention StretchRite, which sold over 15,000 units during nine shows on QVC over a 1-year period. He successfully sold StretchRite Inc. after 6 years. For the next 10 years Scott worked as a surgical sales representative and sold spine implants. He spent the last 2 years devoting his time to developing the KoldRush patent pending system.
Scott was only 13 when he and his older brother Gary toured Arkansas and Missouri on their road bikes, carrying their own camping gear via pannier bags. As an adult Scott rode both mountain bikes and road bikes for a sponsored team based in Tulsa. He won the Arkansas Mountain Bike State championship with the best combined time for the two races held over two days in Devil's Den State Park in Arkansas. Scott raced in the sport category (cat2) at the age of 44. The race season occurs in the hottest months, so heat has always been a factor. After witnessing dozens of cyclist dropping out of the race due to heat-related illness, Scott was inspired to develop KoldRush. As an exercise physiologist he understands the challenge of overheating and how to improve performance.
The KoldRush Engineering Team
The KoldRush engineering team consist of three individual's that bring valuable experience in their respective fields of expertise. Mike Farney is a mechanical engineer and designed the original reservoir and universal helmet insert. Denver Kimberlin is an electrical engineer and responsible for the wireless remote control design for the water pump inside the reservoir. Charlie Wagner is a plastics engineer and designed the final blow mold for the reservoir as well as the seat post attachment (made from plastic injected molding). Each member of the team provided CAD drawings and specifications needed for tooling quotes.
Risks and challenges
Inventor Scott Powers successfully launched a previous sports product (1999-2004) that was made with plastic injection molding. He understands the process and risk associated with tooling. Luckily he has is working with some of those same manufacturers for KoldRush. He has a team of plastic, electrical, and mechanical engineers to help overcome any obstacles that may arise. Scott has access to multiple manufacturers, and because the KoldRush team retains ownership of the tooling, they can control production in the event of any delay. Several components of the product, including tubing, connectors, electronic components, pumps and insulation, are standard in the industry and can be purchased from a variety of vendors.Learn about accountability on Kickstarter
