Guy makes “dodgy e-bike” from 130 used vapes to make point about e-waste (arstechnica.com)

Disposable vapes are indefensible. Many, or maybe most, of them contain rechargeable lithium-ion batteries, but manufacturers prefer to sell new ones.

To make a point about how wasteful this practice is—and to also make a pretty rad project and video—Chris Doel took 130 disposable vape batteries (the bigger "3,500 puff" types with model 20400 cells) found littered at a music festival and converted them into a 48-volt, 1,500-watt e-bike battery, one that powered an e-bike with almost no pedaling more than 20 miles. You can see the whole build and watch Doel zoom along trails on his YouTube video.

Engwe has been around for some time, have one of their bikes (M20). If a part fails, you just need to send them an email, and they'll give you a price and picture of the part and they'll send it out to you. I have had to replace my rear fender and the front light once and they've arrived quite fast (to Europe). Although they aren't high quality bikes, they're priced accordingly.
