Update on our Shopping Center: 7 Mile Cycles is not being torn down, moving or closing its doors! Two new buildings are going to built in the same center that we are in and we will be moving into an all new space sometime in 2025!
We are very excited to see this project come together and look forward to our ALL NEW store at the corner of Higgins & Arlington Heights Road!
