I’m in college and would like a bike that I can use on pavement around town and maybe take on a trail or two. I’m completely new to this and I’m not sure what would be the best brand for me to go with and stay within my budget which is about 0. I’ve found a couple bikes on Ebay that seem ok but I don’t understand what the specs are. So I’ve listed them here. The first one is an Xtreme Ryder Falcon X and I’m not too sure about it. The next one is from the brand Olpran. In the listing it says it’s made in Taiwan with all the other big names but there’s really no other information on the brand. Any information would be helpful!! Thank you so much!!
