Dan in a nutrition coach and this BionX powered Yuba Mundo is part of his healthy lifestyle.  His goal is to drive his car as little as possible.  He was riding a motorcycle around town, then he switched to a "crappy ten-speed," and now he has found a nice balance between the two.  Dan preferred the BionX over the kit that comes on the ElMundo because of the natural feeling of the pedal assist with a torque sensor.  It feels like having bionic legs! This is the first BionX conversion kit we have done (or even seen) on a Yuba Mundo.  It took a little creativity, but it turned out awesome.
