I have been researching for quite some time and decided on this bike..it seems to be everything im looking for but would like some advice. It says 1000w bafang, but how can i be sure its actually 1000w when i go look today?..also cant figure out exactly what brand bike it is..How would i replace battery if i cant figure out what brand? Im going to try to add photos so everyone can have a look. I would like opinions on the bike, people here should have some great info that i cant find on my own. The owner speaks broken English and i have a hard time communicating with him on these questions. Im suppost to pick bike up later today..thanks for any help..i hope to get the bike and hope to have some good conversation with you guys in the future..thanks so much jon
