I have a E-trike(dual front wheels) with a foot brake that cuts off the motor when the brake is applied. My problem is, I stop going up a hill, when I start again, I let off the brake, the trike starts to roll backwards, I twist the throttle and the trike jumps. I am afraid it may cause me to tip over. I have seen this feature on other controllers, does anyone know why this feature exists? Is there any reason why I shouldn't bypass it?. Thanks in advance. Jim

Some throttles have the inadvertant ability to fail all the way 'on'. With the stop disabling the throttle at the controller then this is a safety to prevent an accident or maybe disabling the throttle all together. Since you did not describe the throttle, as in what make and type- resistor or potentiometer nor the wiring layout, it is difficult to help so whatever info you can find would make it easier to recommend a possible solution.
it might be possible to add a second brake that isn't tied in to the controller for holding on a hill.
You can disable most brake switches by simply disconnecting the wires. The idea is that in a panic, applying the brakes will automatically kill the throttle. If you know how to ride, this feature is really not necessary.
Some kind of kill switch is a good idea to prevent runaway in the event of a throttle or controller failure. A main battery disconnect relay is the best.
Thanks for your response. It is a thumb operated 5K potentiometer throttle on a Taiwan trike without a wiring diagram, only an owners manual. Your answer about the throttle failing makes sense . I think mopeds and motorcycles have a kill switch on the handlebars. Hmmm Jim
Thanks, see first response. Jim
