SEM website updated

SEM website updated

For me great news.
The website of the streamlined electric motorcycle has been updated with the latest design, as I promissed two days ago!

A design of which I am very proud, although, it is complex, it is the most realistic electric motorcycle so far!

Many, very many hours were spent on the design, designing the hub center steering, the T-splines aerodynamic shape, the singled sided wheel supports, the drivebelt drive, the agni motor, the mannequin, the sitting positions, the "retro" look, the ... landing gear, etc. etc.

The latest version of the streamlined electric motorcycle was uploaded to this youtube link.
This is the version which will be presented on the website streamlined-electric-motorcycle.com
It is by far the best engineered version of the design series of SEM.

One of the things I always do is make a comparison with other alternatives and sometimes even motorcars.
In this case the comparison is with the famous Peraves Monotracer.
This comparisons shows that one of the main design characteristics is still realized: small vehicle = low aerodynamic resistance.
Remember the design is for a 1.9m 6' 2.8" man.

Single Sided Hub center steering

Single Sided Hub center steering,

for the streamlined electric motorcycle.

As a design excercise I have been looking at a single sided version of the hub center steering. It took me quite some hours to figure it out, make the design and do the renderings, but it is done!

There is a  youtube movie of the design,
a take apart animation so you can see how I solved the problem.
It is now possible to easily take off the front wheel, the double roller bearing is much smaller and consequently lighter than the two sided design.
There is more rotational space on the left side of the hub as the brake disk could me moved more inward.

Below some images to peek your interest.
