Hi all, I posted this question elsewhere but I thought I might get a more technical answer here, hope that is ok
My 73 year old mother in law has always been a keen cyclist. She cycled miles (sometimes 50-60 miles) on an old, step through, very traditional and very heavy bike. Over the last couple of years she's done a lot less cycling because of her knees. I suggested a modern lightweight hybrid bike (not an e-bike) and she got a second hand boardman women's hybrid and gave it a try but she can't get on with the geometry so she is selling that one. She couldn't really afford a new step through e-bike and ideally it would be great to get one that could do 50-60 miles without "battery range anxiety".
There are some "quality" older step through e-bikes with rear pannier battery on Facebook marketplace / gumtree etc.
I've also seen rear rack batteries (with or without the fitting rear pannier) on Ali express with free delivery with 36v 20Ah (giving 42*20=840wah when fully charged?). They claim to be Samsung/LG cells. Could she buy a second hand older "quality" step through e-bike with rear pannier battery and I replace the rear battery/ pannier ? If it's the same voltage but larger capacity will that be a problem? Where is the battery controller generally - is that part of the battery housing ?
Thanks
Pete
