Re: LUNA CYCLE FAT BIKES FOR SALE

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 all o...

Re: A long list of things that you can power from your batte

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...

Re: Friday E-S game: Where is the Fly ? Win a free T-A set

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.

Re: muxus 3000 chugging ?

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!

Re: The wheel-building spoke-lacing thread, post your tips

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 if/wh...

Re: The wheel-building spoke-lacing thread, post your tips

The linseed oil will provide lubrication during assembly -which effectively ...

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...

Re: Changed the fork, what next?

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-Suspension-Fork-2...

Re: Science, Physics, Math, & Myth

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...

Re: Science, Physics, Math, & Myth

Regarding the Blue Plot Line.. Thrust naturally increases as you select smaller wheel sizes, while the torque of the motor is independent of wheel diameter. Thrust is most convenient for estimating the climbing capacity of the vehicle, and it is what most people actually mean when they talk about 't...
