Brian Riley and Kyle Jansen appeared on Shark Tank’s episode 823, intending to get $500,000 to exchange 10% stake equity. Guardian Bikes founders needed a Shark’s investment to ramp up production and push their product to mass retail outlets. Riley, who has an offshoot business of supplying brake components to bike manufacturers, decided to make his bikes after realizing that his SureStop customers were not putting his brakes on their kids’ bikes.

The founder’s story

Riley was a high school student when he saw his grandfather getting involved in a bike accident. His grandfather was riding a bicycle when he was suddenly cut off by a car. Riley’s grandfather grabbed the bike’s front brakes to save himself, which resulted in locking the front wheel. However, the inertia force threw him over the handlebars causing him to fall headfirst. Though he did not suffer paralysis, he escaped with several broken vertebrae.

After the scenario, Riley thought of how severe his granddad’s accident could have been prevented from happening and figured the answer as a university student. In 2012, he launched SureStop, a one lever braking system that equates force on both wheels when the brake is applied.

The bike is equipped with SureStop technology to automatically adjust to change in speed, rider’s weight distribution and the surface. The technology also lowers the chances of a bike flipping over and prevent a lift on the rear wheels in cases of a sudden stop.

Riley later realized that the brakes were not put in kids’ bikes and therefore decided, with his business partner Kyle Jansen to start their own company, Guardian Bikes, which sells kids’ bikes fully equipped with the SureStop technology. The secret to the Guardian Bikes is their brakes. When you squeeze the hand brake, equal force is applied to your front and rear brakes, reducing the chances of injuries or a wipeout.

Guardian Bikes after Shark Tank

After the company’s success from getting $500,000 for a 15%stake equity from Mark Cuban, Guardian Bikes also landed a deal with Amazon, which started selling their bikes online. The founders have ensured that the braking system is installed in their bikes and other brands they work with. The company has also expanded into selling helmets with the same protection idea.

Guardian Bikes’ social media is active with more than 3,000 followers on Instagram and significant Twitter followers. The founders also utilize hashtags to make sure the bikes reach their target audience. A year later, an interview on their blog after signing a deal with Shark Cuban also showed that the duo has big dreams with the investor in making the bikes safe and helpful for the kids.

Guardian Bikes come in three models. A twenty-inch single-speed bike will cost you $319, a twenty-inch single speed bike at $399 and a twenty-four-inch seven-speed bike at $419. The models that get to the client 99% assembled feature Riley’s SureStop braking system. The business has both an online and physical presence. Guardian Bikes are also available in dozen retail shops countrywide.
