Yes. And for a 28 mph on-road bike, certainly so as well. That's why SRAM is doing so well with its 500% Eagle 12-spd series of derailleur drivetrains. And then there's the versions with wireless electronic shifting.
Remember, with eBikes we're normally a 1x drivetrain, that is no front derailleur. So whereas analog bikes have 2 or 3 front chainrings to get the range of ratios, we're stuck with 1.
What about the Q-factor?For a wider gear range, there are a number of EBikes that also come with 2 front chainrings.
Rohloff failure after 11000 miles Video of Rohloff failure
This video is of a non-ebike Rohloff hub that failed because of bad quality control. With the Riese and Muller demand for the Rohloff I can’t see the quality control improving. Will the added stress of an electric drive bike exponentially increase the failure rate?
Richard I agree it is a Rohloff issue but the point is the bicycle manufacture has the system responsibility. Automobile makers address issues like this all the time. If my car’s airbag is defective Honda is responsible and through a dealer the part is replaced. The R&M dealers are on the losing end of the manufacture/dealer/customer relationship. I don’t think Trek sent the defective derailleur back for repair to Shimano, they replaced the derailleur. Hopefully R&M is having some serious engineering discussions with Rohloff because this could be a nightmare in 2 or 3 years when the failure rate escalates.I believe the direction this thread has gone validates my initial concern about the nominal topic. While a few issues specific to decisions made by Riese & Muller have been discussed, such as Ravi's point about Riese & Muller's lack of commitment to establishing service centers in its overseas markets, this thread has largely centered on a component not made by R&M but used by it more often than perhaps any other bike maker.
That component is of course, the Rohloff speed hub, something near universally admired and praised by nearly all reviewers and riders prior to Riese & Muller fully embracing their solution. Combining the "bulletproof Rohloff with the Gates carbon fiber belt drive promised a level of reliability and durability, fully in concert with the Riese & Muller concept.
The choice of using Rohloff so extensively by Riese & Muller has not turned out so well but to call this a Riese & Muller reliability issue is not entirely fair. Clearly there has been a failure by Rohloff to bring service along at the same pace as sales. Rohloff's good name is suffering deservedly because of that. This Rohloff issue that is reflecting badly on Riese & Muller. However this is like blaming Trek because they were delivered a lot of faulty derailleurs, by Shimano that were used in building their bikes that appeared to be per spec but failed after six months of use. This is where Riese & Muller needs to step up more. Regardless of which component is not living up to its reputation, Riese & Muller needs to be more active in solving its customer's problems and not just keep pointing its finger at Rohloff.
Of course all this comes at a time when doing anything about it is more difficult than ever because of more life and death issues than bike transmissions that are confronting our world.
More than ever, I think the title of this thread is unfortunate and unfair.

I agree, but the issue needs to be voiced and hopefully it’s an easy fix. My dealer, Propel, has gone out of their way (as has your dealer) to resolve the issue. Hopefully when normality returns we all can ride with confidence on our R&M machines.Dennis I do agree that Riese & Muller will be suffering a serious diminution of their brand if they don't take action to deal proactively with the issues that Rohloff is causing. R&M built the bike, they sold the bike and they have the responsibility to assure the value of their own product. It remains to be seen what R&M's response to this emerging issue will be. However that won't be for while because of global social distancing and business slow down. I just think they deserve more of a chance to respond before being called out.
The big question is how many bikes have failed ?
Honestly, I am surprised in 2020 that someone from R&M isn't monitoring this board and hasn't reached out to the people reporting problems. That is just Brand Management 101.
I'm guessing it was a push by R&M to get E14 realized, a joint venture between Rohloff & Bosch. A bike designed & produced by R&M with 1 part that is a joint venture between 2 other companies? I realise E14 is now available on other Bosch ebikes but wasn't it exclusive to R&M for a fair while?The choice of using Rohloff so extensively by Riese & Muller has not turned out so well but to call this a Riese & Muller reliability issue is not entirely fair.

Yes EBB and even though i have bought 2 bikes from them they are big on the sales pitch but thats about it, i just hope my recently purchased R&M remains fault free.Population density of Brisbane, Australia is 155 per square kilometre, LA is 3124 per square kilometre.
I'm not sure how many R&M's get sold in Brisbane but where i live in Adelaide, South Australia it's not many, there is no dealer here, the closest is 800km away.
I think this may have something to do with it, as well as the Bosch ebike department over here i imagine is pretty small.
