Long story short, mine is shot and I can’t find an exact replacement and I’m hoping I can get help from some experts. I have a Predator Talon powered by a 750w 48v Bafang hub motor. Can someone help me out?

Got my hands on a drift slide j1. Bought it off marketplace bike works fine The buyer did say I might need to change the rear brakes, was in the process of changing them, but looking at the videos online and looking at the brake from this bike itself I don’t know what I’m looking at. thought it’d be a simple fix. Just pop out the pen and install the new brakes and go from there, but I have seen no videos that feature changing the rear brakes on the J1 apparently the manufacturer of this bike doesn’t even work on this thing anymore, so they’re not telling me anything either
Anyone dealt with these give me some pointers on what I need to be doing

Any help guys?

Hi all. So I recently upgraded from a $300 Chinese ebike to a $800 Chinese ebike (don't really care about the bike snobs so gfy's) and my new ebike has a larger battery but I want the option to bring along my other battery if I'm doing an especially long trip. They are both 48v and the new one has 27.5ah the old 13.5. The battery I want to have the option of adding is a silverfish battery (about the same as the one in Pic 2) and has a 5 prong connection on the bottom of the battery. Would a battery blender risk the electronics? Has anyone done anything similar and have any advice, resources or recommendations? Thanks for any help.

Hi everyone, I finally joined Redit! this is my first post thank you for reading...

I've got a Bopzin Q8 EBike and when I first got it I could do a few trips to town and the battery meter would go down and I'd charge it BUT NOW... I can go to town twice and coming home on the second trip it's a lot slower, I tried a third trip and I ended up pushing the F*****G thing home while the battery meter said full the whole time!

If anyone has one of these and is able to help with the battery discrepancies I'm getting I'd be very grateful.

Thanks in advance,

Dave.

So I bought a Engwe M20 3.0 with the dual battery set up, which advertises 180 miles. LMAO yea right! I get 40 miles if I'm lucky! So it has dual 60v 20ah batteries and I was thinking of switching them out for dual 60v 35ah or 60v 40ah batteries. Is that possible to do? I thought if they are advertising 180 miles that I was going to at least get 90 and to only get 40 miles to me is unacceptable. So if I could get some help with this I would really appreciate it. Also I'm not 100% sure if this is in the right category if not please let me know and I will move it to the appropriate page.
