I bought a folding ebike that isn't "officially" released in the US. It's a Xiaomi QiCycle, and is $800 on Amazon. I've only test ridden it, but so far so good. I'll be using it a lot over the next five days. No throttle-only, but good pedal assist, and three speed internal hub gearing. Battery is in the tube, and has built in front and rear lights.
