I hope that I've posted this into the right sub-forum......

After recovering from an injury last year that had me lower my crank arm distance to compensate, I'm now considering slightly increasing the crank arm length on my 'bent trike's pedals. (I have an adjustable crank arm thingy.)

All else remaining the same, my understanding is that this would allow me to impart more power into my pedalling, making hill climbing a bit easier. Is that correct?

Other than requiring larger leg movement, are there any negatives to doing this?

Looking for a simple, straightforward explanation rather than illustrative formulas and equations.

Thanks!
