I want to learn to uni and have a purchase question. I can locally get an 05 nimus trials(cottrless cromo hub) for $160 or a torker lx. If you have suggestions or advice help would be appericated.

I weigh around 100 and want to get in to street riding.

If you want to get into street riding, I would suggest you get a 20" trials cycle with an Isis hub. Here is a link to a site that carries Isis hub unicyles and here is what they look like(the hub).
