UPDATE: I replaced the twist throttle with a thumb throttle on the unit, as my friend would sometimes initiate the brake lever and she’d still have some twist throttle engagement, which was obviously problematic for her. So, now, with the thumb throttle, the braking lever and thumb throttle are incompatible behaviors, which is much safer for her.
