Eleven years ago I bought Giant Freedom Dx duel battery electric bike for $2099. It has a electric motor in the front wheel and a 7 speed internal hub in the rear wheel. I’ve put over 25000 miles on that bike . When it was new I could get 75 miles out of those batteries using the middle of the three power settings. Today I’m getting about 35 miles out of the original batteries. I recently bought a new mid drive Bosch powered ebike. I paid $3600 for it and I’m wondering if It will still be useable 11 years from now, like my Giant ebike. Ed
