My humble take on E-bike design and contruction

Hi,

Check out this guy's similar take:

He's built other ebikes with recumbent layouts.

Looks like AussieJester, a long time member here

A project by Warren Beauchamp

Looks like Warren, not Kim.

As far as the handlers go have a look at http://www.sportsmanflyer.com

the center of my seat is actually 16% behind de center of the pedal axel, but it does not really matter much for me, the only reason that i have pedals and not fotpegs are swedish laws. without pedals it can't de called a E-bike, but a electric motorbike. And the rules laws for an amature built motorbike is hard and expensive!

Looking forward to seeing it come to life. How long do you expect it to take before you get to go for your first ride?

It's gonna be a while before this thing kan hit the road, I've got more or less all the tubing and other parts but i cant really start building anything before I've desided on what motor and powerpack i want to use.
so all suggestions are welcome!

I only see a Cromotor + 24 FET controller + 2kWh Lipo on this thing

Some aesthetic suggestions (from a complete ignoramus) :

The arched tubing is beautiful - I would continue the arches down to the chainstays. That will increase strength too.

The lower section could benefit from more curved elements, to make the bike more stylistically consistent - it looks a bit like two teams worked on upper/lower sections.

The head-tube area will have a lot of stress and lots of brazed/welded joints. Instead of joining the tubing pairs wall-to-wall, you might consider some web between the pairs of tubing, to add dimension and strength. That web motif can echo other areas that will need web for strength and mount-points.

Cheers,
