Does anyone have experience converting this bike with a mid drive Bafang or Tongshang? My worry is the battery won't fit in the frame...its not a large space. Any suggestions?

Second question. I have a rad power city with a 14 AH 48V battery? Is this battery compatible with a Bafang or Tongshang conversion?

Thanks for the help. Looking forward to ride with my son on some mtb trails. 😀
frame seems a fine conversion candidate. the battery im not sure if its compatible, does it have anderson connectors like bafang? if so its within specs, 48v etc.
looks like a good bike, though a cyc photon kit would likely fit and work better than bafang. the battery looks compatible since the motors meant for use with 48/52v batteries. if it doesnt fit in the frame i recommend going w a custom battery which can vary in size and capacity and fit in the triangle space no problem
