Bike Mission video
Actually, the bike mission song can be changed using motorbike parts. U can have 2 types of songs to choose from. Furthermore, the bike parts now have effects that will apply to battle if u were to crash on it, like increase drop rate.
For vol.2 or vol.3(i cant remember), u get to have a motor part which enables invisibility, just like how the smoke screen works. U wont get detected by monsters when u ride it, and u get a 100% preemptive strike when u crash monsters. Also, if u are not interested in bikes, u will get an accessory when u complete the bike quest in vol.3. This accessory gives u a 25% movement speed in maps and battles, and when u equip this to Haseo, u gain the effect of smoke screen as well. So, u wont have to worry getting into battle when u dont want to.
