Are we really expected to believe that the battery in these new e-bikes is going to last the entire lifespan of the bike? I mean, come on, we all know thats just not how it works. So, can someone please tell me if its possible to replace or upgrade the battery in the future? Or are we stuck with whatever mediocre technology is crammed into these things? And dont even get me started on the environmental impact of just trashing a whole bike because the battery dies. What kind of sustainable cycling are we promoting here?
