Power assist level calcluations? #19

Closed bogardon closed 2 months ago

bogardon commented 2 months ago

“Power assist” is an assistance mode proportional to the power on the pedals. Levels available from 1 to 9. Set assistance levels according to your needs. Value% / 2, maximum 254. For example, applying 100 Watt to the pedals, with 150 assist level, the motor delivers 300 Watt. These assistance parameters are also used in the hybrid mode.

Can somebody explain this calculation to me? I don't understand how to derive 300W from 150 assist level and 100W human power. Thank you.

Assistance levels can be set from 1 to 254. This value is half the percentage of multiplication of human power. So if set to 150, 150 x 2 = 300%. With human power 100W, motor power 300W.
