Endless Sphere

John,

Thanks for dropping by to crap on yet another topic that does not conveniently fit into your box of useful information

What kind of batteries (chemistry) are you using?

I put together a little review of the Luna Cycle 1-1/2 years ago -> http://endless-sphere.com/forums/viewtopic.php?f=4&t=50036 This is a seriously fun bike, with a unique - almost cartoonish - presence that seems to attract attention everywhere it goes. If I did not already own one, I would be a...

Ya, the coaxial plug on the CA is only good for ~1.5A, perfect for something like a CycleLumenator and/or tail ElectroIights that has an integrated DC/DC circuit. I happen to have one of those 90->12V DC/DC converters handy. We could wire it to plug into the charge leads that come off your controlle...

Just need to ask Justin, 'Please?' then send him two motors. One for destructive testing -- and the other for future reference. http://www.ebikes.ca/tools/simulator.html See-> FAQ 'Can you add motor XXX or YYY to the list?' Doing a full characterization of a hub motor takes a lot of our time and als...

1 Fly Power (FP) = 250 Watts, so this must be the Euro-spec model.

I would expect he US model should be somewhere in the 3-5 FP range.

Heh, is that little guy part of their "F1 Technology"?!

Tragic loss for the eBike community.
Luckily, no loss of life ..just melted eBikes
Well wishes sent for the injured firefighter and Ilia.

Nice! Can you share a +/- 50$ estimated cost for these built moto wheel options?

24s A123 cells @ 80V hot off the charger = 3.33V per cell.

3.3V is nominal voltage - ie. used up. That chugging is your pack bouncing off the controller/CA LVC.

3.6V per cell is charged. 24 X 3.6V = 86.4V ..charge yer batteries, zip!

Uh oh.. 7.1.2015 On our way to Copiapó We have finally left Chilecito behind and we’re now on our way to Copiapó! Yesterday, the #ACCIONADakar got disqualified. Thank you so much for your support! 8.1.2015 Message from the Team As the navigation system wasn’t working, we weren’t able to follow the r...

Pray for a safe stage.

That's our brothers out there, racing with capable - but limited battery packs.

Albert's electric car looks a little worse for ware after completing the second stage.. http://www.albertbosch.info/img_contenido/blog/albertbosch_39_B6rQyOSIUAEqhIu.jpg_large.jpeg http://www.albertbosch.info/img_contenido/blog/albertbosch_4_B6rOAhnIQAIT__G.jpg_large.jpeg ..only eleven days left!

Happy to be here!

It is what I have learned after I thought I knew everything that means the world to me.

V is for Vagina

Since we are going a little OT.. Have a couple spares done up when ordering (or cutting & rolling your own threads into) spokes. Poke a hole in the end of one of the grips, then screw a nipple snugly onto a spoke and insert it into the 'bar end. Hope you never need it, but remember it is there i...

We are very sorry to inform you that there are no companies or individuals currently offering that service.

Feeling better now?

The night before building a wheel, I dip the threaded ends of the spokes into a small container (35mm film canister) of boiled linseed oil , then lay them out with the ends hanging over the edge of my workbench to semi-dry. The linseed oil will provide lubrication during assembly -which effectively ...

7. Fit a new #1 plate!!

That should at least make it look faster

Hey, this is pretty cool!

Curious ..how did Y'all pull this moto-saddle-mounted-to-a-bikey-seat-post off?

Happy to be here! Ever since the introduction (and evolution) of Justin's eBike Simulator, it has been the best place to knock around different eBike system designs ..pretty much my favorite video game.. must have literally spent days worth of hours twiddling the dials searching for the ""...

.... I'm wondering if it's not better to sell the bike and get a montague?? Any thoughts? I have a blue Montague in my stable, and I started appreciating it a lot more after reading David (Talking Heads) Byrne's book, "Bicycle Diaries". http://www.bikeblognyc.com/wp-content/uploads/2010/0...

Yep, but the steerer tube is pressed in from below the stanchion/crown, and there is nothing preventing the stanchion from being knocked up and off the steerer tube = poor cwah face planting :shock: Properly assembled, the lower bearing race sits flush on the stanchion. Once the bearing assembly and...

Did you notice that there is ~2" of 1-1/2" diameter tapered steerer tube exposed below the head tube?

That, plus 3" (because the fork is for a 26" wheel) means the front end is about 5" higher than stock(?!)

Seems totally goofy to me. How was the test ride, cwah?

Nice fork, but it is every kind of wrong on that bike. Whoever told you it was for a 20" wheel - they lied -because Rockshox has never made a suspension fork for 20" wheels :| You may want to consider snapping up one of these-> http://www.ebay.com/itm/Mekkem-Recumbent-Electric-Bike-Suspens...

Can we all agree on what 'apples' are, please? -Battery :arrow: 66V 4.6Ah Dewalt -Controller :arrow: 40A IRFB4110 -Wheel diameter :arrow: 23.5" OK, good. Let's put these on our test bench. Aside from the enable switch and throttle (100%), we will NOT touch anything except for the phase and hal...

Your example is apples, but the other part is oranges, and the reason for that is the motors aren't compared under the same operating conditions. Assuming equal copper fill, under the same conditions they would be identical, because for one to make more torque, it makes more heat. John, Since these...
