FREQUENTLY ASKED QUESTIONS

Got questions? We've got answers. Check out our most commonly asked questions below.

All classes at Dragonfly are open to all levels. In the spin room, you are in control of your bike, your pace, and your resistance so you can modify the workout to your own comfort level. In the gym, grab weights you're comfortable with, notify your instructor of any injuries you may have, and we'll provide all the modifications necessary. There are beginners in just about every class, so don't worry! Just go at your own pace, listen to your body, and smile!
If you aren't feeling well or cannot make it through class for whatever reason, we ask you to exit the cycling room or gym with as little disturbance to class as possible. If you are in spin class and feeling fatigued but can make it through, take off some resistance on the bike, sit down, continue pedaling at a medium pace, and drink lots of water!
We recommend that anyone who rides at least once per week purchase a pair of cycling shoes. Our bikes support both LOOK DELTA and SPD clips. If you're not ready to purchase shoes, we offer shoe rentals at $3.
Yes, please! We like to keep account information on file for each of our riders, but it is for Dragonfly's use only.
Yes, we have an array of options available to our members, so please read them carefully and choose the one that works best for you. Fly Deals (recurring memberships) are up to 25% off the rack rate in exchange for a 3 month commitment as well as other terms. Class Packages cost a bit more per class but offer more flexibility. So it really depends on what works best for your schedule and lifestyle.

Dragonfly also offers specials throughout the year, so be sure to check your email and the website for promotions.
Unfortunately we do not at this time. However, if this is something you'd be interested in, please let us know!
Ask your doctor.
It all depends on height, weight, age, and fitness level, but on average you can expect to burn between 300-700 calories in a 45 minute class depending on class type.

Yes, a co-ed locker room is available to store your belongings during class. Please bring your own lock.
No, unfortunately we do not have showers.
