I received the Flow today for my wife (order 1686). It's everything I expected from my original review on October 21, 2019 (

Sleek, refined, great performance and handling. I love the fact that it is so easy to pedal at PAS level 0 ... kind of makes the range a non issue, if I exhaust the battery, I can pedal home just like a regular bike. The programming on assist levels is just right ... controllable and excellent acceleration when you want it. Packing was excellent. I'm thinking of buying the Sport for myself, even though I already have a ride1up 500.
