Just a heads up for future posting for everyone (not picking on ya Sachiel):
ALWAYS POST WHEEL DIAMETER! 18:1 with a 4" diameter wheel is totally different than with 8" diameter. (Even a one inch difference can be up to a 25% different gear ratio!)
And with all due respect to Sachiel, I'll disagree and
refer to my previous thoughts that you can't be both competitively* quick and strong with only one pair of motors and a single speed transmission. Though it might be a good balance, max pushing force or max speed must have compromised in that design.

I definite competitive as a max speed greater than 10 feet per second, and having a maximum applied force of 150 lbs.
