Over the years, we've used a few different motors to add pedal assist to the Mundo cargo bike. The system on your bike will be identified by the type of drive system and location of the battery. Here are descriptions of the different drive systems we've used on our bikes:
eZee motor - Yuba Mundo V3 & early versions of the Mundo Classic
You'll know this system as it is the only one we've used that incorporated a front hub motor. The battery is located behind the seat tube, just under the level of the rear rack. These systems are still supported by shops around the country and parts can be obtained at The eBike Store in Portland, Oregon. Here's a link to the Yuba elMundo eZee Manual.
BionX motor -
We've offered two different BionX systems on our Yuba Mundo cargo bike, the PL350XL with a 48 volt, 8.8Ah battery used on our Mundo Classic frame and the D500DV with a 48 volt, 11.6 Ah battery used on our Mundo LUX (formerly Mundo V5) frame. Identifying which system you have can be done by checking the color of the battery case. The PL350HT's battery case was grey and its hub casing is also a matte grey. The D500DV's battery case was black and its hub casing will also be black. These systems can be serviced by any shop listed on the BionX dealer locator. Here are links to the BionX PL350XL manual and the BionX D500DV manual.
eRad motor -
The most recent version of the elMundo LUX is powered by a 750 Watt Bafang mid-drive motor, provided by Lectric Cycles (eRAD). We offer this motor with a 48volt, 11.6Ah battery and color LCS display. Many shops around the country will service these systems and troubleshooting information may be found on page 12 of the user manual. You can learn more about this electric mid-drive system here and you can find the user manuals here.
