Anyone had any experience with these yet?

Anyone had a chance to see the innards?

Any opinions on reliability or efficiency?


Dear Meb,

There was some speculation and (I think) some links to
patents in this thread a few months ago:

or

At those prices, it may be quite a while before anyone finds
out about reliability.

Thanks for the info. We had a smaller internal gear hub thread
couple of months back at ARBR in which this hub was briefly discusse
in less detail than the thread you cited.
The higher step up ratio of the Nupace might have more use on
recumbent than other bikes, but that is a non-trivial efficienc
penalty even relative a mid-drive particularly with that price tag

It's a ridiculous, patentable development some people will buy.

Later the price will go down. The quality may go up or down.

From where I sit, it looks like the price will fall only if one of two
things happen; the hub actually sells well enough to get mass-produced
by a more economical method than prototyping construction, or a
speculative investor has a mass-production run made either for
inclusion on a bike that will be marketed heavily, or for sale as a
separate unit. I doubt that the latter scenario will come to pass for
a variety of reasons[1], and at the current price, there's no danger
that the former will have any chance of obtaining.



[1] Pick one or mo Bike sales are not particularly brisk anyway,
and this thing's not sexy enough to change that; even mass-produced,
it wouldn't get into Wal-mart high-end territory, so it would still be
too boutiquey to attract the mass-market mentality; investors with the
funds are likely to be looking for a much less risky thing to back;
the patent may not be viewed as being defensible enough to keep the
investment from being endangered by copycats if the concept actually
sells; the product isn't viewed as being sufficiently proven to
attract an investor; it isn't available in blue; it wasn't invented by
a name-brand entity associated with somebody that has the clout to get
the backing.

Let me guess: you're either a salesman or a public-relations flack.

To some extent, I've been both, but these days I'm a screen printer,
among other things.
