I don't really understand your comment. The "regular" version of the boosted board had a single drivetrain. The higher-price one had a dual-drive train but if you are doing any speed at all and one of the drives fails.. you're going for a tumble. I have ridden both, waited forever for the long-range boosted that was always promised as "any day now" and switched to onewheel and am glad to have done so.
