The Aero has been designed to satisfy the “Need for Speed”. The design builds on the best features of previous GreenSpeed trikes, including the SLR race trike which has dominated Australian Pedal Prix racing for the last ten years. Thus the Aero is a road version of the SLR, with more speed features to make it the fastest production trike in the world.
Streamlined Aerodynamics
At 20 mph, 80% of an ordinary bike rider’s energy goes into pushing the air aside. This is what makes it so much harder to ride into a headwind, than a tailwind. On the Aero you’ll LOVE headwinds! Because when you turn into a headwind on the Aero, you will leave the competition behind, if you haven’t already.Even the cross member on the Aero is streamlined. This is because a streamlined tube has 1/10th the drag of a round tube! The more the seat is reclined, the smaller your frontal area is to the wind and the faster you go. The seat of the Aero is reclined at a low 20 degrees. Wind tunnel testing shows a large gain in speed when using wheel covers. Most bikes and trikes cannot use front wheel covers due to instability in cross winds. The Aero overcomes this and further reduces drag by using 16” front wheels with a 20” rear wheel.
Lightweight
The frame of the Aero is non-folding, plus the seat frame is an integral part of the main frame so the weight of hinges and other joints and fasteners are eliminated. Plus the frames are mutually re-enforcing, and thus the whole structure can be lighter and more aerodynamic. We have used 7005 aluminium alloy for the Aero. This has reduced the weight of the frame by over 3 pounds, or 30% over the Cro Mo 4130 prototypes. Although the axle size has been increased from the 12mm of the SLR to 15mm on the Aero to reduce axle flex, the weight of the kingpins has been reduced, as has the front hubs, by totally removing the outer flange. Even the weight of the special GreenSpeed Scorcher tires has been reduced for the Aero.
