I cannot see a direct drive work... you need some gears... these motors run at / up to 10k RPM... and even with a very small wheel you end up with very high power draw to get moving but quickly you are way too fast... even when driving w PWM.
Instead of vibration motor think of 2 free running nano servos... PWM driven.
