What is the widest tire I can put on this?

Max would be a 26x2.5 in my opinion. I used a hookworm and it worked out well. To translate to moto rim, look for conversion charts online. This company sells a 19" moto rim, one could assume compatibility...

Is there a specific crankset needed for the frame? If not, what are your recommended dimensions?

Not specific request ; 42T is ok ; If you have further problem or need , please you contact me by Email (sqma1001@hotmail.com), My WhatsApp account is +86 13401536906; China

what is the maximum battery size that can fit in it?

The battery size is 350mm*137mm*220mm , 20S14P;The battery size is different according to the cell arrangement way,If you have any further questions, please feel free to contact me by email（sqma1001@hotmail.com)
