"About three times a day, Rich Benoit gets a call to his auto shop, The Electrified Garage, from the owner of an older Tesla Model S whose car battery has begun to fail. The battery, which used to provide several hundred miles of range, might suddenly only last 50 miles on a single charge. These cars are often out of warranty, and the cost of replacing the battery can exceed $15,000."

"Many EV and e-mobility batteries are difficult to repair by design, and some manufacturers actively discourage the practice, citing safety concerns. The small number of independent mechanics who repair EV or e-bike batteries struggle to do so affordably due to design challenges, safety requirements, and a lack of access to spare parts."
Digital products are deliberately designed to fail, deliberately designed so they can't be repaired. More profit if you make it e-waste

Are E-Bikes worse than contemporary pushbikes in this regard as far as parts that are present in both are concerned?
@robryk Yes, very much so. Most standard bikes just use standard mechanical parts. If they use unusual mechanical parts that can be an additional problem. But e-bikes often use unusual e-bike parts as well as unusual mechanical parts.
