Motor Driver Selection

Hi,
I have chose the motor for self-balancing scooter. The spec of the motor can be seen in the attachment file.

Right now I have to choose which driver is suitable for my motor. I have narrowed down to three drivers and the specs are:

Type: LW24VFR

L*W*H: 120mm*98mm*41mm
Current Limit: 75A
Continuous Current: 20A
Direction: Forward/Reverse
Nominal Battery Voltage: 24Vdc
E．M Brake(24Vdc): None
Suitable Motor: 600W Below

Type: LW24VGB
Weight: 1KG
L*W*H: 162mm*115mm*56mm
Current Limit: 120A
Continuous Current: 40A
Direction: Forward/Reverse
Nominal Battery Voltage: 24Vdc
E．M Brake(24Vdc): Yes
Suitable Motor: 600W Below


Type: LW24VG
Weight: 880g
L*W*H: 142mm*115mm*56mm
Current Limit: 70A
Continuous Current: 20A

Nominal Battery Voltage: 24Vdc

Can anyone give me some ideas or suggest which driver is the best match with the motor? Why?

Thanks
