Is there a limit on the Rohloff ?
You can push 2500W thru Rohloff on the 11th gear (the most strongest gear) and it will work fine.
Optibike has been using Rohloff for over 10 years with no issues and they push 1500W.
Gear 7 is the noisiest because that's where the second step reduction happens but I only use gears 6,8,9,10 and 11. 14 gears are kind of redundant but it is what it is.
Rohloff should make ultra-strong 8-speed system especially for ebikes. That would be nice.
esthetically pleaseing though?
Wattwagon is not marketed as a sleek, elegant bike but rather a heavy-duty workhorse and no-compromise performance design.
There are lots of sleek and very well-integrated bikes but the tech keeps evolving. This is not like cars. If you had a Lexus, you could run that thing for decades but how many of us here carry a phone that was designed in 2014? Very few....
Similarly, a good system should be forward/backward compatible.
I have a nice Haibike Sduro Trekking 9 that is integrated and delightful to look at and it's a Bosch
I have had few Bosch bikes. Really nice bikes for sure but having ridden Stromers for over 15,000 miles.. I can tell Stromer is a powerful beast. So, whenever I rode a Bosch, there was thought in my mind...
mmmm it would be nice if Bosch made slightly more powerful motors (atleast 500W motors instead of 350W).
Bafang Ultra + Rohloff +Gates is a beast of a totally different league. On level 1/2, it feels like 1 Bosch at its peak power , on level 3/4, it feels like 2 Bosch motors @ peak power combined.
In the coming week, I will be doing some 150 mile (240Km)/day weekend rides in preparation for my record attempt and it is totally crazy to think I will just carry 1 battery and 1 charger.
On Bosch I used to carry 2 batteries and 2 chargers and it would still take 10 hours of riding.
