Are budget Amazon e-bikes like Jasion, Funhang, and TST actually reliable?

Consensus across r/ebikes is mixed but generally positive for the price: many owners report thousands of trouble-free miles, while others flag early component failures (brakes, hub motors, controllers). The recurring advice from specialist communities is to budget for upgrades to tires, saddle, and brake pads, and to confirm UL 2849/2271 certification before buying. These bikes deliver strong value but rarely match the build quality or support of premium brands.
