Yuba has just released the 4th iteration of their Mundo cargo bike and managed to trim six pounds from the complete bike. In our estimation, that means you should be able to shuttle a bit more of your favorite beverage home on the next B-double-E-double-R-U-N before tapping your legs out.
The frame is based on their El Mundo and has myriad mounting points for virtually every electric power/motor system out there, including front-hub dynamos and mid-line motors. Weight savings comes from better component spec, but price remains just $1,099.
