The Frame: - Dimensions: 18" Tall x 14" Long x 10" Wide (12" wide with wheels) - Light and strong 3003-H14 aluminum alloy - Telescoping Handle constructed of tensile strength aircraft aluminum - Handle telescopes to a height of 38" - Safely rated at a 300 lb. capacity - Holes in the frame make it lighter while not compromising structural integrity About The Bag: ZÜCA makes the bags from many fabrics but the basic bags in black red and navy are premium 600 Denier Polyester that have been coated on the inside with polyurethane to improve water resistance and seam strength. The bag is water resistant to a point, but should not be left out in a steady rain with stuff inside that should not get wet. ZÜCA uses a very strong type of Velcro (it comes in different adhesive levels) so that the bag is unlikely to come undone due to the interior load pulling on it. About The Wheels: The wheels are 4" polyurethane formulated to absorb a great deal of the shock of hitting a curb, and to make the wheel silent over rough surfaces. ZÜCA makes their own wheels so that they can control the quality of the urethane in the wheel. The flashing mechanism uses no batteries and is powered by a small generator or "magneto" inside the wheel. The magneto rotor is in the wheel and contains a coil of wire wrapped around steel plates. The wire is connected to the LED's, and as the plates pass the magnets in the stationary armature, a small burst of electricity is generated and the LED flashes. The faster you go, the brighter it gets. And what's up with the upper wheels? They are there to make curbs and stairs easy and eliminate the BANG-SCRAPE sound. They don't light up, so if you want to be stealth you can switch uppers for lowers. Our Package also includes the tensile strength aircraft aluminum steel frame. + Plus + as a Bonus receive our Universal Ipod and MP3 Deluxe Gift Set.
