Hi @WaldWhen i built my ebike with the Ultra motor combined with the Rohloff hub, i noticed at my first test ride that shifting is a "delicate" process with such a powerful motor. Especially because since then i was only used to derailleurs.
So when reading trough this thread i got interested in how is WattWagons realizing smooth shifting with Bafang/ Rohloff combination?
Are you using one of those shift/ gearsensors? But do they actually work well with the Rohloff?
From the https://kindernay.com/faq/Does the Kindernay shift under pressure?
What about if you are doing a throttle, just release and shift ?From the https://kindernay.com/faq/
Upshift: It is possible to upshift (to a higher/heavier gear) under close to full pedal power.
Downshifts: It is possible to downshift (to a lower/easier gear) under load, but the rider must slightly reduce the load on the pedals during the shift.
That being said, I would not recommend shifting under load - whether it is Rohloff, Kindernay or even a regular chain cassette. In my experience it grinds down the teeth ever so slowly, and those add up over time.
I would recommend easing off pedals for a split second before shifting. It becomes very intuitive after the first couple of time you do it.
Interesting, so just like you can ruin your manual transmission in a car by grinding the gears with bad shifting technique, same applies to the IGHYes. Almost like a stick shift car.
Yes, that's what i had to learn first. but you get used to it pretty fast.
Cool, so basically you created the first manual clutch for an EbikeYes, that's what i had to learn first. but you get used to it pretty fast.
However, it wasn't satisfying and i wanted to shift quicker.
So i made myself some sort of "clutch button". The red button labeled with the "horn" symbol is connected to the brake circuit from the motor. Whenever i press it the motor gets shut down, just like when pulling the brake lever.
So when i want to shift i press the button, reduce pressure on the pedals and twist the shifter, then release the button and hit the pedals again. When i get the timing right i can shift and accelerate pretty fast!
