the 'hulabike' is pretty cool too: http://www.bikeforest.com/hulabikes.php

"I am awestruck by the sheer irony of the thing" That seems to be the real purpose of the treadmill bike. either that or: "The Treadmill Bike's hard wearing belt offers a sure grip while protecting your feet from dirt and other contaminants commonly found on the earth's surface." See...

jeez - I should look at the whole picture before I click submit. If you do use that 2 series into 1 connector, it's got andersons on the two battery sides, bare wire on the controller side. So you'll want to put andersons on the side that goes to the controller and you'll need andersons on end...

actually that 2 into 1 connector does say it wires two in series to 1 output - so it should work, probably be nice and neat too.

>Cut the andersons off one end (leave some wire to work with) - solder > that to the wires coming off your battery space pack (I mean solder the long end to the battery space pack.) The short end you cut off you use to make a jumper.

If you don't want to buy andersons and tools to crimp them, just get the 30" extension (anderson's at both ends) from ativ - it's $10. Cut the andersons off one end (leave some wire to work with) - solder that to the wires coming off your battery space pack. Then you solder the ends of the two...

Widely mismatched motors run 1 at a time for different conditions might make sense - lightweight geared motors would be better than direct drive for that approach. Here's someone who's done that: http://www.wisechat.com/carl/2stage-rocket.htm

This one is still a pilot, and it's hydraulics, not air but: http://www.epa.gov/otaq/technology/420f05006.htm http://yosemite.epa.gov/opa/admpress.nsf/b1ab9f485b098972852562e7004dc686/371449ddfa7c264285256fa4006c109c!OpenDocument

Thanks for that D-Man. Just now dawns on me the full coverage fenders I was going on about probably won't work for the FS bike. The rear rack already gives some protection to your backside - I'm not sure you can to much more back there. At least the controller and wiring get some protection...

Huh - just looked at the wikipedia article on NiMH's and it says a fully charged cell can be 1.35 - 1.4V ... at 1.4V that would be 56V total for 40 in series (54 for 1.35 each). Mmm - now I'm wondering if I want to pull apart my 12V booster pack and pull out a cell just to be safe. Or I can...

I think I'd encourage using nuts and bolts to hold the battery on - you don't want the screws ripping out while taking a corner. I just got some Planet Bike full coverage fenders for about $27 as I recall. They say 'hardcore' but they're just polycarbonate with no metal reinforcement. Still...

Nice setup. Did you use the battery bracket attachment supplied by ativ to put the battery on the rack? Their website implies it's 'only' for the Old Man Mountain racks, but I always figured it could be adapted to something else by drilling some holes.

I was thinking a Bakfiets with a hub motor ... but that wouldn't be "Excellent Indoor Transportation" like this thing!

It was a puncture - just a _really_ big staple that barely got through the tire and tube.

Actually that first ride was pre-electrification. I rode into work for the first time today - I liked it. I don't have a speedometer on the bike yet so I can't give any stats but on flatish (including slight uphill) terrain I was pedalling easily on my 48 tooth chainring and smallest sprocket...
