I've read some reviews of that unit, and while some liked it, I found quite a few who had problems, from lower-than-expected power to early failures.

I didn't have an option for the shutter from an OEM recently so I ponied up for the SON deluxe, and it has been absolutely excellent. On a 406 front wheel, coupled with a B&M Luxos U, it puts out great light (really wide pattern, and auto-brightness, and auto-focus as speed increases/decreases). During the day, even when riding at 8-9 mph (with the kid) it puts out enough USB power to charge my phone while it's running all background processes + strava. On tour, it kept my phone and my little action video camera running all day every day.

It was nice not having to worry about power or light at any time.

That's more than I would spend on an generator. I had no problem using my 13400 mha battery pack on tours, it would charge my android phone 5 times. My will be a 700c wheel, so your 8 mph is my 12 mph. 3 watts is 3 watts and .5 amp is all that it has, is it will charge a 2500 mah battery in 5 hours of riding. My purpose is maintenance and worry free lighting.

My old friction generator is 6 watts, 5 amp.

I received my LE CG PA1 Osram Ostar projection LED. I will use in my headlight.http://static6.arrow.com/aropdfconversion/28315f36fdedfee60d491e3ed1cfe1b7d0745bd1/10990830282201536le20cg20p1a.pdf

I wonder if I can take a few turns out of the dynamo winding, make it 4 volt,.75 amp as the LED forward voltage is only 3.5 volts, it should give 1.5x brightness. Otherwise I could run two Rebel Luxen LEDs in series ( 2.9 vf) on each phase..

I received the supra2 kool stop brake pads and dynamo hub.

The PV-8 hub is tiny compared the Shimano DH-3n31-nt. They both have the same number of poles. The wheel will be cross 2 lace.

388g vs 705g:



I also worked on the seat frame, though the 7/8x.028 tube is hard to work with..bend ect.

I like the hub dynamo, but I think I am going with something like this for my corovelo. I use a 12 volt, 4 pound motorcycle battery for my fan when it is hot.

I received the rim today, Thanks Ebay!

I also received spokes, so assuming my spoke calculations were correct, I can build the wheel! (thanks Dan the spoke man)

I was a little confused on holes in the rim. Inside the rim the holes are offset opposite than the spoke hole, they're drilled on an angle.

... laced up and stressed, cross 2.. weight: 1 kg with brass nipples and and without skewer.

Well I lace up the wheel, and like a dummy I didn't check the dynamo beforehand, absolutely no continuity. Seth was right it is a POS. Ebay seller is getting a negative feedback from me.

I am sorry it didn't work out, Tony. I was all excited to buy and lace up a pair of the SPs for our bikes, and although the reports of bum hubs were definitely the minority, there were enough of them that I got cold feet. I threw money at the problem and went with the SONs (and the OEM did the work and ran the wiring for a good price).

I hope whatever you decide on works out. I do love a dynamo hub now that I've been using one. For me, it takes a lot of hassle out of ride planning and I think makes for a safer ride.

I filled out an online form for a warranty claim with the manufacturer, then hit submit button..

quote:
Now you will be able to order “Deposit TWD 1000” (roughly USD 33) from Paypal.
Once you complete the deposit for TWD 1000, you will receive an order number from Paypal.
The Paypal order number will become the service number for your claim.





Heck if Im sending $33.

So then I requested a return from the seller, Open Box Sports.

My warranty claim has been accepted by the manufacturer. They are asking for a serial number, but there is none on the unit. I still have to pay the refundable $33 and DHL will pick it up.

.... Hub is on its way to Taiwan for repair...

Ridiculous that they won’t just send you a non-broken one. Good thing you have several months until you will need it!

By the way, what kind of mesh are you using for the seat? I'm considering a similar arrangement for my next bent, and I see you don't use 'tensioning straps' (which should make it much simpler).

I don't know what Tony's using, but Phifertex works well and isn't too expensive. $15 for a square yard here, which is a couple seat's worth sewed directly like that.

I'm not exactly sure what is the analogue to get in Russia... maybe ordering it abroad might be an option.

Im using pet resistant screen from Menards. Its PVC covered polyester mesh, one direction has twice the number of threads. Its also available at Joannes fabrics, there it has the save weave both directions, better for air cooling, less strong, unravels easier so ends need to be hemmed. Both work. Put the higher thread count across the seat.

Joining it you can hand stitch it, sew it by machine, use PVC pipe glue, and clamp or weld it by melting the pvc coating and clamping. Look closely, I used all three methods.

This time I used similar to the ADC method: (https://sites.google.com/site/recycledrecumbents/seat-covering). Yes it cant be retensioned. SWB seat I did differently, I laced it up underneath.

Great, thanks. HOwever, I've dug up a 3D mesh (a poor man's ventisit) from Aliexpress and it *seems* like a good option as well. Seems extremely tough, if not as tought as real deal, and seems *just* wide and long enough for my fat ass with trim removed.

I've ordered the cheap 3d mesh and tried it out. It's definitely not a "ventisit" substitute. It's much softer and a lot thinner. It'll compress nearly completely under bodyweight, unlike thicker ventisit. It's also pretty stretchy.

The stuff I got is also not a good mesh substitute. I don't think it would make a decent sling seat fabric. I've still got most of a yard left, and I ordered Phifertex for upcoming seats after yanking on the 3d mesh to see if it would be suitable.

The cheap 3d mesh made decent headrest cover fabric, but it makes some crinkling sounds, which right behind your ears could drive you insane. Used as in that link, over a foam seat (or hot vinyl-over-foam seat) it'd be useful.

I replaced all the gummed up brass nipples with fresh aluminum nipples. Will true the wheel later. I need to find a place to mount the shifter.

1/8" paracord rope wrapped over the entire length of the frame is a new seat fabric trick that I've recently applied to a stationary exercise machine.
Tie the cord to one end to the frame and then wrap, round and round, all the way to the other end with no gaps between the cords.
Seems simple but it took me three tries to understand how to get the tension.
As you go pull each wrap as tight as possible. Compact the cords so there are no gaps between each wrap.
My seat required more the 500 foot of cord.
Comfort wise ... By far the best stretched fabric seat yet.
