Hi Martin,
It depends on the age of your driver, but if you have the provision to fit the Electric Brake system, then it's much easier for the younger driver to use.
If you're only using one motor, and a 'Differential Axle', then you should be able to fit the brake Drum / Band to the opposite side to the drive cog. Depending on which brake system you use, you should have enough space between the wheel and the body, and a clear run for the cables and the Hand Brake rods etc.
I'll explain the theory of 'Electric Brakes' for all those not familiar with the system.
The 'Brake' is really an 'Electro-Magnet' which clamps a disk, which locates on a 'Dog' (keyway) on the end of the motor shaft (well it is on mine).
The brake is 'On' when there is no current to the electro-magnet, but when power is applied, the solenoid activates and releases the brake, allowing the motor to spin freely.
When the power to the motor is cut, the control box applies the brake after a second, by cutting the power to the Electro-Magnet.
It sounds complicated, but works really well. The Control Box is the key, and it's quite an expensive piece of kit to buy as a stand alone unit, but most modern Mobility Scooters have this feature.
Hope this has helped someone,
Keep Busy,
Regards,
Mark.
