Once you are registered, you can go to any Bike check-out station and request a bike. The staff will give you a key and helmet and then you head to the racks. Racks are typically blue and marked with UMass Lowell Free Wheelers decals just like the decals on the bicycles. Simply match your key number with the appropriate bike number and you can unlock your bike. Be sure to lock your bike securely before returning the keys to any of the checkout stations by the close of operating hours.
