HOPEFULLY TILTING ELECTRIC TRIKE HOW TO

At that price they could easily have included a common and inexpensive 7 speed internally geared hub. Which given its final retail of ~$2500 US (~$1800 KS early bird) is frankly laughable. Those numbers are fine for flat ground but the least little incline, especially with a load, and pedaling will prove quite difficult given that the bike weighs almost 50 lbs (22kg). It's Gear Inch (gi) is in this odd place, 46 gi on the low end and 60 gi on the high. The TRIS Light, the one without e-assist, has only a 2 speed Sturmey Archer 'kick' shift rear hub. Well, once again a bike company that only gears their bikes for flat ground. Additionally, parking-brake devices built into the tilt-blocking and front brake levers keep the Tris Bike from rolling away or tilting over when left unattended, so no kickstand is necessary. When stopping, riders can use a handlebar lever to block the tilting mechanism – this keeps the front wheels sitting vertically straight, so the trike stays upright without the need for riders to put their feet on the road. They can also pivot a maximum of 60 degrees to either side, giving the trike a relatively tight turning radius. Sort of like an upright version of the Polish EV4 semi-recumbent e-trike, the Tris Bike incorporates a mechanism that allows the two front wheels to tilt up to 30 degrees relative to the chromoly steel frame. The Italian-designed Tris Bike addresses that issue, with tilting front wheels that let it lean into turns. Referencing the diagram above illustrating Yamaha’s leaning multi-wheeler strategy, the scooter would fall into the utility and commuting quadrant in the bottom left.While some people like the added stability offered by trikes as compared to bikes, the things can actually be tippier when cornering. If Yamaha does produce this vehicle, it would be designed for short trips and delivery services much like the EC-03. Tusjii Eiichirou, one of the inventors listed in the USPTO patent, and Nobuo Hara who is listed in the European patent, have both worked on patents for other Yamaha leaning four-wheeled vehicles that never made it to production. Before the Tricity, Yamaha had been toying with other leaning multi-wheelers, most famously with its four-wheeled Tessaract concept. We know Yamaha is working on several leaning multi-wheelers like the Tricity and a sportier-looking variant we recently uncovered in Japanese patent filings. What’s less clear is whether we’ll see Yamaha turn these patents into a production model. Yamaha has previously announced it would introduce more leaning multi-wheeled vehicles, but the assumption was they would all be variants on the Tricity and its parallelogram link tilting mechanism, but these new patents indicate Yamaha is considering other methods of making three-wheeled vehicles tilt. This allows the entire rear tilting mechanism to pivot up and down to handle bumps in the road. The rocker arm is connected to the rear suspension system which runs a shock under the scooter. At the same time, the left rod is pulled forward, causing the left swingarm to go down. The rocker arm pushes the right rod back which causes the right swingarm to pivot upward. 6, below, illustrates a lean to the right. The rocker arm rotates when the vehicle leans, causing one swingarm to rotate up relative to neutral while the other rotates down. The swingarms each extend downward from the pivot point where they each connect to a rod (45L and 45R) which are connected to a rocker arm (43). The two swingarms pivot around the same axis (identified by the line A1 in Fig. What’s different is the second rear wheel, a second swingarm, and a complicated system that allows the vehicle to lean. The battery is also stored in a similar location beneath the seat. The vehicle in the diagrams shares an identical front end, frame, and seat as the EC-03. The scooter illustrated in the patents’ diagrams resembles the Yamaha EC-03 electric scooter currently on the market in Europe.

The USPTO patent puts more focus on how to minimize the increased weight of a third wheel and battery while the European patent focuses on the electric motor controller. The two patents are for two separate processes for the same electric three-wheeled vehicle and its leaning mechanism. Unlike the Yamaha Tricity which has two wheels at the front and a third wheel at the rear, the patents are for a scooter with two rear wheels, each driven by an electric hub motor. Patent and Trademark Office and the European Patent Office for an electric three-wheeled scooter. Yamaha has filed a number of patents with the U.S.
