tanong lang!

is there anything i could use to set up on my underbone bike to hold an extra helmet. hassle kasi when you are driving and you just put the extra helmet on your arm when you want to pick up somebody on your way to a destination. i have seen a hook underneath the bike's seat and the bike's manual said that it's intended to hold your helmet but shouldn't be used when driving the bike for safety reasons. sometimes i am using a backpack just for that and my classmates are laughing because how come a college student would bring such a huge bag when all we need is a notebook, hehehe!!! i need something that's not bulky or barely visible on my bike. help naman dyan mga bro!!!

If the spare helmet is a full-faced one, you can put it on the front end of your seat and squeeze it with your legs so it won't fall. Kung half-face naman, bili ka na lang ng hook na pwede ilagay sa bandang harap sa ibaba ng instrument panel.
