Abstract
A wheelchair having an electric motor power assist controlled by a sensor that senses the manual force applied by a rider to the hand rim. An arrangement is provided for facilitating adjustment of the sensor so as to permit accurate adjustment without requiring special tools or gages. This mechanism includes an LED that outputs a signal when the sensor signal output is zero. In addition, an arrangement is provided for facilitating the adjustment of the spring and also for ensuring that the hand rim is axially located so as to preclude cocking and binding.
