get an ultra pro high version and cut the bars to your preffered dimensions. then get new griptape and grips. because if youre a beginner that setup will last you a while.
BUT if you have alot of money n stuff i recommend getting a threadless sealed headset, a threadless fork, a new brake (prefferably a flexfender style brake), new wheels (metalcores), and either get scs (swish has a pretty cool scs system on doggscooters.com) or just buy ics compression
