I started trials around april, and now i stopped it with a "good" balance ( i a that kind of guy who can fell from his legs even when im standing) and i just need soe ore practice at there ( do not laugh about this progression :/). I just got a " new" mod bike ( i nearly broke it because of the lack of knowledge lol) and it was waay ore better, altough it was around 5 kg lighter then the other.
2 things: if you can, buy lighter parts. tartybikes are awesome, helpfull guys, i recomennd them
Practice. Practice. Even more practice. Trashzen.com is a good website to start with, but you can find good videos on youtube, or in here, at beginner trials chat topic.
Last thing: you can always ask question here. This forum helped me a lot, here i got my new parts for my bike, got lots of information, and spent a lot of time at chit chat at school when i was bored. If you have any problems, ask here, someone will answer it.
