You still don't see the point I am trying to make,

Niranjan weights aroung 50Kgs. he could lift his weight much faster than any of us at 70-80Kgs.

He is new to the sport so he hasn't yet developed the muscles or skill to do so yet.

I think at that weight he could be able to use the standard. Or probaby not, and he needs a triple or an electric bike or a motorcycle.

The only point I am making is that to know that, he could have a gradual training and perhaps able to do so this season.

What I think is to go and push himself to go to 20% gradients like you like to do on that bike and when isn't able to do yet could have a negative impact on his motivation and on his knees.
