I used 2.5" where's because my personal philosophy is that the smaller the wheel you design for the small your gearbox can be. I posted this because I fear I am missing some torque related risks of small wheels.

The chain is #25 because small wheels should (if I did my math right) require less torque to move and rotate.

Are there any disadvantages of 2.5in wheels I may have missed? (assuming that high centering is not an issue)

Doesn't that mean that you would have to assemble the gearbox directly onto the drivetrain, instead of assembling it somewhere else and mounting it on? That would be more annoying imo. From what I can see, there's space to add some mounting holes and avoid that complication.
