Only two that I would feel completely safe from breakage on.
And Orion's are far stronger than Madd Gear scooters. Every version of Madd's scooters has broken. There's what, one report of a trashed Orion? And for the record, zero trashed Flight's.
Dude trust me, they aren't that strong. In fact I'd say you'd be better off with a v2i. A lot more than one has broken.
