Launch a Bikercoin daemon
(bikercoind) from the command line.
Wait until bikercoind is synchronized. You will be notified with several green "SYNCHRONIZED OK" messages.
Run simplewallet to start the Bikercoin wallet.
Create a new wallet or login in the existing one. Either way you will receive your address and will be able to start mining.
Start Bikercoin mining from the daemon or from the wallet. (Type start_mining at the simplewallet console)
