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.

You pretty much should only buy one from a shop that has a physical location near you and can do repairs. Like everybody around me sells Trek, so if I ever got one, it'd be a Trek with a Bosch motor. Bike shops will not repair ebikes they don't sell, even though they'll repair regular bikes. And neither Trek nor Bosch are going anywhere.
