This is a Brakeless Fixedgear With a Flip flop hub and a freewheel. So you can set it up to be a brakeless freewhell giving you one option to stop the bike. Jump into the brushes.
This maybe the worst idea ever This Brakeless bike has studded tires. To stop a fixie you need to stand up and shift you weight over the front wheel and for anyone who has rode studded tires on ice knows that you never shift your weight if you don't have to. So riding a bike that forces you to shift your weight around this seems extra smart.
