I got a good laugh out of this review "Watch my brutal cheap Walmart e bike. You can find it on Tiktok.
If you have been reading Bikeforums for any time at all you will see lots of horror stories about Walmart bikes being poorly assembled. I've seen it up close with a kid taking the cycling merit badge. He went through three bikes in two weeks. The first one had the cranks fall off before we had completed 2 miles of a 5 mile ride. In the end he gave up because the bike was so heavy compared to his own weight that it was horrible to ride. The most recent one was being behind a kid an his mother as they were returning a brand new Walmart bike at customer service. There were just too many things wrong with it to bother fixing it. If I were buying anything with a lithium ion battery I would not buy the cheapest thing available. Too much chance it might be defective. Earlier this year my brother had a battery catch fire while being charged and it caused a house fire. He was quick to cover it with a fireproof blanket used to snuff out stove fires but not before it sent smoke and soot throughout his house.
