start with something cheap if your a beginner that way replacing parts is less expensive and easier to do if your a more experienced rider go to something more expensive like fit or Sunday then if your a advanced rider get things like Hoffman Haro or eastern. trust me the brands do matter so yea do research and find the bike your more interested in I like to ride betweent gts we the people and odyssey but my friend loves Hoffman haro and eastern so yea picking the right bike makes all the difference especially cause you want to get used to your bike also best to buy things that are normally expensive but on sale so you can save money cause trust me youll definetly need things like tubes tires and maybe even rims somtimes
