Clever new Rohloff e-shifting

[mark sutton]

Have been speaking with one of Rohloff's tech chaps this past week and he let me in on this little development. OEM spec at first and with Bosch drives to begin with, but with scope to go beyond that in future.

Of interest to anyone with a Speedhub in their collection too as retrofitable: https://cyclingindustry.news/rohloff-introduces-electronic-shift-system-with-widest-transmission-ratio-available/

200 millisecond shift - why that is exactly the same as is claimed for Audi S Tronic.

They both know we've no way of measuring it to check.

But I've got an Audi so I could possibly/theoretically find some means of accessing diagnostic data, whereas a Rohloff E-14 isn't going to be coming my way in a hurry. Unfortunately.

Yes but with Audi you dont need to take your foot off the gas..

The E-14 is fitted to "my next bike"

That and a belt drive would save a lot of drive train maintenance.

My thoughts too, although the E in E-14 could likely introduce a few problems of its own

How much maintenance do you do on your drive train? Mine gets one squirt of gear oil every 10 weeks approx!

My first chain and front chainring was trashed after 10 weeks.

Jeez! Mine lasted 3 years and 4000 miles. Maybe you should change your motor rather than the gears. It'll be a lot cheaper.

No more than E in Ebike.

Been riding my Rohloff none Ebike since 2004, and the SpeedHub just gets better as each year passes.

I like the idea of the E-14, although is it realy nessacery, one day I may buy a Ebike with CD drive, and the plan is to remove the antiquated derrailure system and use my Rohloff SpeedHub.

To my mind though, Rohloff could do better, and team up with Bosch to have the SpeedHub gearing embedded into the CD motor unit, this would in my opinion be a far better solution, for the gearing of an Ebike.

Having the gearing built into the CD motor, would simplify the rear wheel setup, and remove unwanted weight from the rear of the bike.

Continental already have an ebike with CD drive that has internal gearing in the motor, this is definatley the way forward, and one day will become the norm for Ebikes.

Would be good if it were not an exclusive Rohloff/Bosch arrangement. We probably don't want total market dominance by any company.

Bosch is already too heavy. A Rohloff is too heavy as well. Put the two together and you have double too heavy.

How much do think this motor/gearbox combination will cost when fails out of warranty. Currently Bosch motors are about £600-700 for exchange motor.

With separate IGN you can transfer it to another bike.

 

[Rohloffboy]

On the contrary d8veh, by combining the two, there would be an overall weight loss, compared to current set up's using the Rohloff Bosch combination, like what R&M do.

If it works for Continental, then it work even better for Bosch & Rohloff.

Trevormonty, I don't see the cost as an issue, if you want an ebike with Bosch motor and Rohloff igh the cost is always going to be high, just like the R&M at £5k which arguably is a stupid price to pay for an ebike, although many pay upwards of that for none ebike's.

What the industry needs is a company to mass produce an ebike with CD motor with embedded gearing and a decent battery.

It's not rocket science and I recon with the right volumes such an ebike could be brought to market for under £2k.

Look at what Tesla have done with the new Model 3, they have almost halved the cost of producing a decent EV compared to there previous Model S.

Of course it all down to market expectation's and I guess ebikes in reality are quite niche still, especially as they are restricted to 15.5mph, and many folk still would not consider one for commuting to work because of the this.
