So many features, so little room. The patent pending Ballare dolly weighs at around 50lbs, yet supports 600lbs with up to 3 seated riders. The mast and seat system attach, remove and adjust with no tools, and the entire unit can be quickly broken down to fit in a duffel bag. The system uses no less than 42 ball bearing systems, a stainless steel fastener set and powder coated, computer milled, 100% aluminum construction for a lifetime of use. The patent pending tracking system dynamically adjusts width and approach angle, so it can be configured for virtually any type of track, wether it be curved, straight, non-paralell or completely uneven! There's simply too much to describe in terms of the feature set so we'll let our Ballare Dolly Overview do that job for us.
