Re: heavy rider spokeless integrated hub motor. Discuss?

Even with current manufacturing, metal, synthetic, and carbon technologies, a QUALITY purpose built e-bike (or bicycle) HAS, and will likely continue to have typical spokes regardless of all cost and expense!!! Even with unlimited financial backing and the latest technologies available for professi...

Re: Graphene, possible non-battery uses in bicycles?

Carbon, graphite, graphene, and other, are NOT organic,.... but rather a non-metallic (or semi-metallic) element, common in mineral compounds and essential to organics and many synthetic polymerizations and infinitely more. They are working hard on stripping graphene, and other carbon allos from gr...

Sorry,... I well understood your "aggregate" crack to be more a perception of understanding. Based upon what we know at the moment,.... we can still theorize, and I take great delight in this as do others. Looking over a vast nearby river valley,... I KNOW it's there.

Re: Graphene, possible non-battery uses in bicycles?

Some of the biggest issues here are likely from a lack of clear distinction and definition. While all graphite's are carbon, not all carbon is graphite. As an allo of carbon, one of many hundreds, graphene is as unique as diamonds (ALSO an allotrope of carbon). But graphene it is a very specific de...

Re: heavy rider spokeless integrated hub motor. Discuss?

If the Luddites here had their way, carbon frames would be made by gluing carbon fiber tubes together. Calfee, Crumpton, and Trek OCLV frames are all made by gluing carbon fiber tubes together. There are probably more Trek carbon fiber frames out there than any other kind. Yes, I have seen them, an...

That's not how this forum works. Its rare to have a thread being split, not because its rarely needed, but because its a PITA and nobody wants to do it.

Re: Graphene, possible uses in bicycles?

To be fair, I had heard about graphere a while back, but I was waiting to see it in the news before I read up on it. Thanks to some of the useful links in this thread, I now know a little more. Graphene can make carbon-fiber bicycle frames even lighter, while making them stronger at the same time. ...

Re: heavy rider spokeless integrated hub motor. Discuss?

However the numbers pan out for respective wheels, what seems certain is, that a cast wheel will remain exactly as it left the factory, indefinitely, barring traumas. Clearly this is often not so with spokes. This simple statement alone would greatly interest any consumer who has ever had to deal wi...

Re: heavy rider spokeless integrated hub motor. Discuss?

A rare constructive counter argument post, was that cast wheels lose the advantages of prestressing. A good point, but not damning. Its the bottom line strenght/weight/cost/durability that counts. By way of discussion tho, given prestressed cast concrete is as common as, what are the chances of impr...

OP again here with a gentle refocus. We are all full of it til some numbers are produced, as I have said. That said, what seems inarguable is that cast wheels vs spokes, are as 3d printing is to welding pipes together into a structure. Sure, there are current issues w/ 3d printer "ink", but other fa...

Re: heavy rider spokeless integrated hub motor. Discuss?

Sorry, this is a really, really, really stupid discussion now. Someone that can rebuild a wheel, lace a motor in, and changes and adjust spokes everyday, are not the consumers that will have problems. There is no way I would have broken a cast or composite wheel in 18k + miles. I didn't break a spo...

I do take naysayers point re the suggested rear wheel cant be rebuilt. Meh, as others have said - who would rebuild a wheel today anyhow? But yeah, its more an issue if you have to toss the matched hub motor too (its not just the motor cost, heavy dd hubs are ruinous to airfreight). SO, if any of yo...

Sorry, but I just have to laugh at people saying spoke is better, then they go on to talk about how often they have to change spokes, adjust spokes, etc. Exactly the reason this thread is saying, that a solid composite or cast wheel would be better. I've broken a total of 2 spokes, and pretty sure ...

Re: heavy rider spokeless integrated hub motor. Discuss?

I replace spokes almost every day. They're almost exclusively on OEM wheels that were not built well to begin with, or have suspect unbranded spokes. Pedicabs break a fair number of spokes too, especially once they've been repaired by nincompoops a few times. It's not uncommon for me to deal with 4...

Re: heavy rider spokeless integrated hub motor. Discuss?

Dunno, but it seems spoke fans are avoiding a point which has been glanced on a few times here, which is that with all thes spoke number alternatives, does that not mean an off standard number of spokes needs an off standard hub motor? ie, one with the correct number of spokes holes in the rotor/hou...
