Kate Gruber

It only took one indoor cycle class back in college, and Kate was hooked!  She loves the simple yet effective movements that push the body to the max, and that euphoric feeling you get when class is over.  After moving to St. Louis to pursue her TV aspirations (Kate is an Emmy award winning newscast director), the gym she worked out at didn't have a spin program, and Kate kept begging for one.  The owners finally said "If you teach the class, we will buy the bikes"...and the rest is history!  15 years later, and Kate still maintains the same level of passion for indoor cycling that she did back then. Shehas taught at numerous fitness studios including Flywheel Gold Coast (where she met Tracy)!

Kate brings a high level of intensity and motivation to her classes. Her motto is "it can be easy or effective, not both". 

While indoor cycling is Kate's first fitness love, she has also completed the St. Louis half marathon, the Madison Full Marathon, has hustled up the Hancock, and is looking forward to training for her first triathlon, perhaps 2017?   

Kate lives in Naperville with her husband, Matt, and her two young sons Will and Jack.  In her spare time, Kate loves cooking, reading, being outdoors,  and eating chocolate chip cookies!  

Peter Byskosh

Born and raised in Chicago, Peter has been passionate about sports and fitness his entire life. He has played competitive soccer, volleyball, cycling, and dance since early childhood.

Peter studied traditional Ukrainian dance, ballet, and ballroom for nearly half his life. Being part of Hromovytsia Dance Ensemble allowed Peter to travel the globe and perform in two world tours of Western and Eastern Europe and various festivals throughout North America.

Aside from dance, Peter has participated in a wide variety of Marathons, Ironman Triathlons, Urbanathlons, and Gran Fondo races across the United States. After taking his first cycling class, he was hooked on the workout! Peter is thrilled to become part of the WheelPower family where he can combine high-energy music with a heart pounding workout and help riders reach their fitness goals. 

Ashley Asher

Ashley grew up with an active lifestyle and it has made a big impact on where she is today. She played soccer in college and graduated with a degree in Exercise Science. After working as a physical therapy technician, she decided she would rather be on the proactive side of healthcare. Insert personal training and group fitness.

Ashley is an ACSM certified personal trainer with a love for helping people see all that their bodies and minds are capable of. Her favorite part of her job is watching people do things that they couldn't do before they started working out.

Ashley treats everyone like an athlete. Be prepared to SWEAT when you hop into one of her classes. Gain power, strength and muscle tone while having a blast. She guarantees you will enjoy working out as much as she does.
