It's not a track bike.But it does appear to be built before 1900.I'm guessing the age to be pre-1900 based on the chain--it looks older than the later skip tooth type of the 30s.And the cottered cranks.It also has the standard style of hub(no freewheel)Standard or fixed gears hubs were the first style of hubs--then came coasters and freewheels.Fixed gears bikes were offered by most companied for a lone time.I'd stay off that seat but the bike looks very rideable.The seat pan is built of plywood and might brake at this age,a replace ment seat would make more sence than taking a change on braking the original.Tires are still sold but cost over $100 each.Are you sure you want to ride?Get the second set of rims you got built up and have fun---This is a wheelmans type of bicycle.---try their site---sam
