Don't worry. Their LIPO batteries will die soon, just like LIPOs in other gadgets, and they will be too expensive to replace. Then the e-bikes will be relegated to the basements or garages, two flat tires and a dead battery.
Also, take a look at the article linked in 3alarmer's post #96 above to get a full understanding of what the hazards and problems are with LIPOs. It's worth the read.
