Hello I am allowing myself to attach a first draft of a document that I have prepared to guide in the determination of the levels of assistance in an EBike. It is not a final document, as soon as I receive my Domane+ SLR6 I will finish field checking and correct it as necessary. I hope it's of your interest
I have also opened a new thread in this forum for discussions exclusively related to levels of assistance on an E Bike.
Methodology proposal to establish the assistance levels in an E Bike
Hello, allow me to share with you a first draft document that I have prepared to guide in the determination of the levels of assistance in an EBike. It is not a final document, as soon as I receive my Domane+ SLR6 I will finish field checking and correct it as necessary. If you cycle...electricbikereview.com
Thanks for sharing your draft. Much appreciated.
The Trek App allows you to fine tune the motor output through 9 settings: Max Power, % Assist, and Pedal Response, for Eco, Mid and High. I'd be interested to see what tuning values you start out with when you first hit the road on your e-bike.
Given that pavement, weather, wind, cadence, speed, grade, nutrition, 'legs', mood, etc. fluctuate within and among rides your values may need broaden from those the workup suggests. For example, if motor assist were set at 142W max, then anything steeper than 11% would require a reduction in speed, eventually getting so slow as to undermine stability and steering control, whereas a higher max W would allow for higher speeds. And don't be surprised if the enjoyment factor starts kicking in, when you could keep putting in a solid effort, but what the heck, why not relax and enjoy the breezy tailwind feeling Eco provides.
So, I'd be interested not only in what tuning values you start out with, but what they are a week, month and 3 months later.
BTW, here's a cycling power calculator to possibly play around with.
