Hi!Thanks.Dui said:Wow, that's an amazing build, kudos!
We need more pics and more descriptions, don't be shy!
I'd like to build this kind of flat sheet frames one day, but I always wondered: how do you attach the main tube for the front fork ? (sorry, I'm not sure how it is called in english, I mean the tube with the bearings which connect the frame to the steering column?)
I believe that's the critical part to get right, would you mind explaining how you did it?

Thanks.John in CR said:Sorry to read about the motor. What do you think the weakness was...poorly centered bearing cup, inadequate bearing support, a loose wire in the winding?
Am I looking at the pictures correctly and the headtube piece is only bolted to the frame, or is it welded? I'm always terrified of a failure in that area and opt for overkill in my welded connections.
The aluminum case of the battery has good durability.John in CR said:I've been thinking about your battery layout, and I have some concern regarding the lack of compression applied to the individual cells. Every electric car battery I've disassembled has had compression force on the 2 faces of the cells. It is an important part of the battery structure affecting both capacity and cycle life.
