Complete your Ride
We had an outstanding experience at Cyclerie! We purchased two Aventon e-bikes, and the entire process was exceptional from start to finish. The staff took the time to help us choose the perfect bikes for our needs, recommended all the right accessories, and even installed our bike rack on the car before we left.
I had a terrific experience at Cyclerie! I love the bike I bought and working with Skip was great. He told me about customizing features that are available on the bike if you use the Aventon app.
I enjoyed my buying experience at Cyclerie. Ideal location, easy to get to, easy access to trails to test ride. … Salesperson was helpful, knowledgeable and easy to work with. No pressure to buy.
