Also the only problem I can see is connection between motor and wheel, direct drive would be best.

I think you need to rethink this. Is an FP at, say, 12:1 better than a CIM at 3:1 (assuming an FP spins 4 times faster than a CIM)? It
is better than an RS 775 geared to the same speed, by a torque comparison, but this is not because its ungeared free speed is higher.
Up to efficiency losses, motor power is pretty much all that matters.
