Endless Sphere

Hi All, It's been way too long since the last update. Kits have been sold out for a while now, and I have been too busy with other things to resolve some production issues and build more. There have been a mountain of set backs, and issues with 3rd party part compatibility and I feel like I don't ha...

Yes, he is going to be missed. I was lucky to meet Farfle and his dad at one of the Barstow races where his bike beat Luke's Death bike for a 2nd . PaulD took 1st. I still own one of his cool rear swing arms. Farfle was ahead of his time and I'm sure would have gone far in life. So sad to hear. Sup...

Strange since this display works with a BBSHD stock controller, but doesn't work with ASI's BAC855.

If the display works with a BBSHD, did you try setting the ASI to use the Bafang protocol?

Hi Nobreaks,
It's TBD at the moment. I have a lot going on right now, but I'll try to post an update in the coming weeks. Thanks for your interest!

Hi, I've never seen one of these in person. Can you tell us more about the performance? Noise? How about the mounting system?

Let’s say you reduce torque requirements in half or a quarter; high speed low torque. From a rider perspective the feel of a always having a small tailwind. How how light of a system can you get to. I would assume with such low torque requirements you can use lighter materials and a much smaller mo...

I am only thinking about a 12 speed system because at the present time they are the only ones that have a cassette that works with the XD Driver , unless something in a 9 , 10 , or 11 speed cassette that is XD Driver compatible just became available ? I would prefer a 9 speed system like I have now...

Your narrow-wide chainrings , are they 11 speed ( chain ) or 12 speed ( chain ) chainrings ? Rumor has it that most narrow wide chainrings work with 12 speed chain, but shimano chains need to use a SRAM quick link. I use a Shimano 11-46 11 speed cassette, and it's enough range for me and it's a fra...

Paul, can't you put a strain gauge of some sort on the pulley to detect torque from the crackset? The idler is only on the motor chain, so it would measure motor torque not rider torque. The Rocky Mountain power play does this by routing the bike chain over the motor sprocket and the chainring such...

Hey Paul, the new kit already shows as sold out on the web site. Is there a chance to get a kit anytime?

Yes, things moved much more quickly than expected. The next batch is scheduled for June. I have a few used kits that need to be refurbished, but I'm not sure when I'll have the time.

One more question - the throttle version, is that going to be the PAS version plus additional input for throttle or does the throttle version change/remove the PAS function in any way? The throttle version also has a torque sensor, so it takes input from either. It doesn't remove torque sensor func...

110 asymmetric is the Shimano Ultegra/Dura-Ace chainrings yes? How does that affect the chainline? What I really want is a narrow-wide 44-46 ring. I currently have 110BCD ones. I know there are also 130BCD rings of that size. I can't however find much anything bigger than 38-40t in 104BCD. Is there...

I already put an order in(order22) can you hold off on delivering until the throttle version is ready?

Ok, will do, Dave. Thanks for your order! i'll keep you posted.

Great news, I see there is no mention of the throttle. Is that still supported and does it use the higo/bafang plug?

The throttle version should be ready next week. I'll be building cables this week, and yes, it uses the 3 pin Higo, same as Bafang.

Hey Paul!
ETA?

Gen 2 kits are now available on the website! Thanks for your patience!

Can the freewheel accommodate 110 BCD or 130 BCD?

The freewheel is 104 BCD only, but I have adapters to run 110mm asymmetric for those that want to run double front chainrings.

Now these are out https://www.harley-davidson.com/us/en/m ... bikes.html. Too Cool!

Looks like a Stacyc. Oh. just checked and Harley purchased Stacyc.

Paul, I think there's a market for a smaller lower powered version of your system for kids bikes.

I definitely want to do a smaller lighter system some day. Do you think a torque sensor or throttle would be better for kids?

Same Plugs ?

No, it's a standard female DC barrel on the battery. The customer plugged into the light connector located on the display cable (which is a male DC barrel) with a 3rd party charger.

Just some entertainment for everyone stuck at home due to the pandemic. This is what happens when a customer connects their charger to the 6V headlight circuit of the ASI.

I just measured my bikes and it looks like your q factor is only +5mm of my widest setup, nice. Apparently the narrower the better for biomechanics. Compared to most mid drives your system is pretty narrow. Kudos on that! Yep, for some people narrow is really important, I totally understand. I real...

Probably both. When my gym switched their exercise bikes to ones that had an additional inch of pedal width ( 7 inches vs the previous 6 ), i stopped using them because they hurt on both legs. A 3mm offset can be easily overcome with a pedal washer on one side, but yes, a 6" (152mm) q factor i...

Oh darn, that's not compatible with my bizarre leg issues ( i know this from riding other mid drives ), glad i asked before ordering. GL with your really cool drive system otherwise. Is it the q-factor or the offset that's an issue for you? Interesting. That looks a lot like Sempu but not quite. Ho...

Will you be able to supply a female to fit to the battery I supply and possibly another male plug to fit to whichever battery charger I end up using ? Yes, I can include this with kits shipped without batteries. We use an XT60 connector which is quite common. What’s the front chainring 42 tooth? In...

quick question, does one pedal have more outward offset than the other? if so, how much? wanna know if th q factor is even. With the new torque sensor, Q-factor is about 180mm for a 73mm BB. I measure about 90mm each side +/- a few mm. I switched from Miranda 4mm offset cranks to 0mm since the Erid...

Things have been a bit quiet around here (i have not been back for quite some time myself) but its nice to see you have been planning/scheming/working away in the back ground developing this product and still carrying the torch of innovation! Very tidy, I commend you on your effort and vision. By t...
