2018-12-09 Thread Paul Compton via EV
Drag is usually measured in a wind tunnel and is the force needed to force a vehicle through the air at a given speed. From this drag force you can calculate the required torque at the driving wheels and derive the power required. Cd is a figure derived from the actual drag. It uses air density

Conventional motorcycles have appalling aerodynamics. In the UK, learners were limited to machine of no more than 125cc and 12bhp. You could expect a top speed of 60mph. My Scirocco EV would also do about 60mph on that power (as read from the gauges). The Microlino is the right kind of shape,

A small/medium motorcycle and rider generates approximately the same drag at 60mph as a Nissan Leaf. You're not going to get 200 miles of range from a smaller battery at realistic speeds. On 4 June 2018 at 19:52, brucedp5 via EV wrote: > > >

It sounds like Nikola hold design patents, not invention patents. These are much easier to obtain, but also much easier to get around. Often the reason for taking out a design patent is solely to be able to say you hold a patent. On 3 May 2018 at 05:35, Cor van de Water via EV

I set my Scirocco conversion up by using a set of slide plates. They're mounted on bearings that allow them to only move laterally and the amount they move as the vehicle rolls over indicates the toe under load more accurately than the normal method. I'd set up for a small amount of toe-out, so
