Ok soo many people have made topics asking these sort of things so i thought 'hey ill make a topic to put them all together!' Here are some basic things people ask: Whats a mod or stock? A mod is a trials bike with the smaller wheels (20" on front and 19" on back) A stock is the original design of the trials bike, the bigger one with 26" wheels. What is Bump? Bump is when someone posts a new reply in their topic so that their topic is active again, and it will be moved to the top of the forums, so more people see and it gets more interest (used commonly for selling things)... It basically reminds people the topic is still there What does 'lol', 'lmao' and 'imo' mean? Laugh Out Loud and Laugh My Ass Off In My Opinion These are the only things i can think of that need to be stated at present, but if there is anything else i should add, please say and i will add it in
