Rohloff has developed an electronic shifter for their Speedhub and will start selling them on select e-bikes only. E-14 will eventually make it's way to bicycles.

When they add this to the normal bikes for the IGH it will be great to change flat tyres especially at night when you have to line that doodad with the twin cables up again back on the Hub.

There has been an Australian company offering one for many years, as I said one of the other times this was mentioned.

with the German Companies resources they made theirs smaller..

it also went in place of the cable drum on the external shifter...

E bike obviously has the battery to power it's stepper motor..

I have two Rohloffs and have never had an issue aligning the external gear box with the hub. Quite easy actually. Biggest gripe is it is a bit of a pain to replace the shifter cables. I wish my Co-Motion had the shifter cables were fully enclosed so they would not have to be switched more often, i.e. 10k vs. 15k miles on my Thorn which are fully enclosed. You would think Co-Motion would get this easy fix right.

John ,

Co Motion has the internal coupling separated, bare lower wires shifting?

the external shift box uses a pair of housed cables running the entire length, to the thumbwheel attached cable box,
that rotates the shifting sequence cam.

internal to external shifting conversion parts are available from Rohloff USA .. a division of Cycle Monkey in Richmond Cal.

you can route cable pair via top tube or downtube.. to that cable box..

I would be very interested in the Rohloff IGH if it had electronic shifting, especially to eliminate two extra cables off the bike as well save replacing them all the time. The only thing I would worry about with it would be if it had decent electronic cable joins and better then dynamo hub joiners which only last a couple of years if your lucky.

My Co-Motion Americano has external shift box. Yes, the shifter cables from the just below the head tube to just past the bottom bracket are bare wire. Unfortunately, the cable guides under the bottom bracket do not allow for full housing. The rest of the shifter cable, i.e. from the shifter to the head tube and from the bottom bracket to the gear box, are enclosed. I agree they "should" run the entire length but they do not (or at least they did not in my bike which is several years old). My Thorn on the other hand does have it fully enclosed.

In order to "fix", I would need to have the brazed on cable stops replaced with pass-thru cable guides which allow full housing.

Nope, unnecessary... Just run the whole length of housing over the BB then, skip/bypass the under the BB cable guides..


there are self adhesive zip tie fixtures if just using tape & zip ties doesn't appeal to your aesthetics....

I know, I know. But I just really don't prefer to zip tie something unless an emergency. Just seems cheap to me. Co-Motion should just do it the right way, fully enlcosed. However, if I were planning a very wet and/or muddy tour, like the Prudhoe Bay to Inuvik tour I am planning to do, I would very likely consider it.

So ask them* to make another custom frame with the features you desire, sell that one when it's done.

* I haven't been in Eugene in years, but they are a relatively small company.. right there..

so can do things big Importing Brand names cannot/wont.
