100 W
For my Maxun One solar bike, I want to develop a 350W high efficient and light weight mid drive motor, see here: http://www.avdweb.nl/solar-bike/hub-motor/cyclone.html.
Instead of a chain drive and I want to use a spur gear. And using a protecting by housing to avoid dust.
If I’m not wrong, a 8620 case hardened 12t/90t spur gear, 16 DP, pressure Angle 20, thickness 0.3” should handle 350W easily, I have used this site for strength calculation:

Here is a drawing which was created automatically by Inkscape, you can print it 1:1, take the DP16:
Spur gears are standardized according this formula:
Diametral Pitch [DP] = tooth number / pitch diameter [inch]
Spur gear theory:

Who has experience in this field and can give me help and advice?
