Self balancing bicycle prototype using flywheel(reaction wheel)

Hello everybody,
Well I'm a level 4 mechatronics students from Mauritius and doing my project on a self balanced bicycle which uses a flywheel to achieve this.A better view of it can be seen on:

During the past 3 weeks,I've been struggling on calculation of torque(flywheel motor) and I'm stuck.
I have been using the formula T=J*alpha,
where J=moment of inertia and alpha=angular acceleration.

I have assumed overall mass of prototype to be around 2.5 kg,radius of flywheel=5 cm,mass of flywheel=0.5kg,radius of driving wheel=5 cm,max permissible tilting angle=30 degrees.

Could you please help me in selecting my 12V DC motors:flywheel motor(rpm,torque)
Driving motor(rpm,torque)
and flywheel specifications(radius and mass)
and finally if gear box(reduction gear) is needed,its ratio??
Thanking you all in advance.
Best regards

Self balancing bicycle prototype using flywheel(reaction wheel) not know how it changes...maybe by default...need to remove url...just edited it..
