I hadn’t owned a bike in over ten years. The customer service shown to me when I came in was great, the salesperson (I can’t remember her name, she was a blonde woman) was very helpful and understanding. The cherry on top was the thank you card I just received in the mail! I’m loving my new bike and will be using Trek for all my bike-related purchases moving forward.

Zane was fantastic to work with. He helped my son find the right bike while helping other people at the same time. I really dug the vibe of the store and it makes me want to purchase other bikes there.

Hats off to Algonquin store service manager Miguel Torres Garcia. I stopped in on the fly today to have my brakes adjusted for an upcoming 20-mile ride. Miguel did the adjustment on the spot, patiently explained the finer points of bike brake systems and quick release wheels, expertly answered my many questions about Trek bikes in general and even gave my bike a quick once over to make sure everything was in working order. He was exemplary and I will definitely be taking my and my family's bikes there for servicing anytime they need it.

Can't say enough good things about this place. Just a few highlights that I had today.
I wanted to get my bike checked out prior to a triathlon I want to race. Even though the store was pretty busy with appointments, they managed to find time to take care of my bike in just a couple days. The store owner even drove out to my home to get it to me on time.
Super appreciative of the knowledge / kindness the store employees demonstrate, and their dedication to the people who walk through their doors.
I'll definitely be bringing my wife's bike by for the next tune up as well.
