I agree what you said. I really like my Orbea gain with rear hub X35 motor, I have learn a lot how deal with it and now I am upgrading some parts in order to reduce bike mass. Next step is to buy a batterie extender ( dificult to find it).

This video shows how a hub motor like X35 is biuld. As per Mahle specs. there is a 14:1 gear ratio and 40Nm max torque.

Let me attach son info regarding rear hub X35 sensor. Also I add an segment of L1 and L2 showing variations of power delivery. In fact if I increase my cadence ( rpm of rear wheel) power delivery decrease, Mahle recomend to keep around 70 RPM pedal cadence.

Hello r1roman. I would like to know a bit more about the setup you are using with your Bianchi ebike. It will be very useful for the purposes of this forum to know the methodology that you followed to customize your support levels in the X35 system. As you know, the purpose of my development is...

Welcome r1roman. Practice makes perfect, I totally agree with you. We have to ride a lot to improve and/or stay in shape. The years weigh too. I am sure that you will help us in this forum with your experiences especially with the X53 Mahle system.

When you set up the power of each assistance level you are definding a maximun output power, but when you are in that level you will receive power in the range of 0 to that maximun. The max power will not be permanent and constantly delivery.

X35 system does not have torque sensor. It is just a rpm sensor installed aside the casstte in the rear wheel.

Hi Stefan, now your case is clear for me. Let me say that what you are doing is great. Be sure that your fitnees will be growing every day. Try to do a +little effort every week ( in a controlled way) and you will feel body changes.

Hi ngg, " they are neither theoretically nor practically possible, since a bicycle cannot give more power than a cyclist. This is the basic setting of e-bike operation. " can you elaborate on it.

Many interesting points of view. Let me digest them and I'll be back soon.

It has taken me some time to understand the data you provided about the 43.09Km run on flat ground but based on 623 Wh composition, 1.9 hours of total duration of the route, your contribution of 142Wh and the Ebike 481Wh, come to be in term of average power (during the entire route) : 74.4 W...

Thanks Stefan for your fast answer, just and additional question: is there a ways to separate the data power into assistance power and your power in the BLEvo app ? Are those info in the excel report you mentioned?

I'm going to pause my development to analyze the case that Stefan shows. A few days ago I myself was surprised by the data that Stefan showed and I asked him for confirmation of it, but like NGG, there is something suspicious that seems to disagree with the theoretical and the real that I have...

I like to see all these comments and points of view about this new and interesting topic. All comments are welcome and will be attended.

Hello GrumpyOldMan, I would like to know if you are using the Mahale app with the Auto Assist feature. I am very interested in getting feedback on your experience, performance, ease of use, usefulness, and anything else you can say about it. I will appreciate your comment.

Hello NGG, I am glad to know that my post finds space for observations, discussion and improvement. You are correct with your comment, but as I have mentioned these extreme hypothetical scenarios do not exist in reality, they are only for educational purposes and to show how the battery power...

Let's not forget that the power available in the E-bike battery is a finite resource and that it will allow us assistance with certain limitations. Next we are going to use the cyclist exercise "Y" and its power assistance levels to analyze extreme possible scenarios. Scenario 1: we are going to...

Hi Stefan, I will do it in the next days.

Let's define the "Y" cyclist who is out of shape and let calculate his custom assistance levels. The power profile of rider "Y" is W/Kg=2.3 and the rider's mass is 75Kg which means his FTP is only 173W. This rider is going to need permanent power assistance to level out his power profile at 3...

Earlier I discussed the use of assist levels. My proposal for the use of assistance levels is based on ranges of terrain slope. What it means is that the steeper the terrain, the higher the level of assistance will be applied. We are going to advance in the development of this methodology...
