My 10-15 year old Schwinn AirDyne Exercycle was in need of a complete overhaul. No Schwinn dealer/repair shops in area but new ones available through Sears and Amazon. Roberts Bicycle Repair agreed to do the job. It took awhile for Robert to find the appropriate parts and during this process was told the older AirDynes were more sturdy than the new ones. One parts company sent him the incorrect parts and would not correct their error without additional expense to Robert. Ordering from another parts company was successful - all this took Robert several days and time on the internet and phone. Robert then did an excellent job of restoring my AirDyne and it works like new. Not cheap, but you often get what you pay for. I will take my AirDyne back to Robert in about 5 years for what I hope will be a less expensive tune-up.
