    Axial Lifter?

    Fun, fun, fun. I've been thinking about a ducted circular wing lifter for years, but recently the idea of a counter-rotating coreless axial prompted me to draw one up. Seems to fit together nicely, has balance and symmetry, but,.. does this thing have a chance in hell of getting off the...

    APL's Pressure Contact Battery box

    This thread was split off from the custom ebike build thread, found here: "APL's V4 Cruiser Build" https://endless-sphere.com/forums/viewtopic.php?f=6&t=111159 Well, with lots of head scratching and figuring I guess it looks like a 60v pack is going to be the best fit, and not weigh a ton...

    Frame building fixtures.

    Thought I'd open up a thread on fixtures of various types and designs, frames, forks, whatever. Pictures, links, parts, anything fixture. Just to get this stuff in one place so people can get ideas on the good, the bad, and the ugly. It seems that there is no such thing as a perfect fixture...

    APL's V4 Cruiser Build.

    Oh boy, a new build! Hopefully I won't belly flop on this one, but you never know, I've been pretty good at that lately. :oops: I came across several 13s/10p - 26ah batteries a while back, and it's either use 'em or lose 'em, so I need a new frame to put these big boys in. I decided to go...

    Crystalyte mid drive motorcycle.

    Thought I'd show the E bike/motorcycle here. Not quite as powerful as most of the bikes seen here, but interesting just the same. Started out as an E bike experiment, but the pedal part didn't pan out. The '48' is in reference to the wheelbase, which is about as short as it can be...

    Hub motor, mid drive, cog mount variations.

    I thought it would be a good Idea to do a short 'how to' on the DD motor mid drive-drive cog set up. In case future builds are interested. If you have another way to do this, then please post it here. Also, if you can think of another way of saying 'mid drive drive cog', then put it on here...
