How to measure my inseam for a bike
Your inseam can help you find the perfect sized bike (measuring it properly is similar to pant inseams but measured a little differently). Here's how they work:
Stand upright with your feet 6-8" apart.
Using a tape measure or tailor tape, measure from the bottom of your foot to the top of the inside of your leg.
Compare your inseam measurement to the standover height of the bike. You should have about an inch of space between your body and the top tube.

My heavy eBike was stolen. I bought the Judd Retrospec because it was about 20 pounds lighter and easier to put on the bike rack. The pedal assist system took some getting used to, but with each new discovery I liked the ride more. I'm 80 years old and ride with a group of older men. I ride in the back of the pack because with my new bike I can ride faster than any of them!

Awesome option for city commuter train combo
I was looking for an e-bike that wouldn't be so heavy to lift onto a subway or commuter train and this fits the bill! Most e-bikes are so heavy or you have to sacrifice speed/battery life to get those lighter weights. The bike also looks quite stylish. I ended up getting the basket for the handlebars since this doesn't come with a rack, so now it's a lot more versatile for carrying my backpack or other items. Would be cool if there was a case to go with it?

Less. Is. MORE!
I was nervous about buying this bike with no reviews and was worried the price was too good to be true. I have to say, this bike has blown me away. It's fast, ultra lightweight, great looking, and you just feel the quality when your riding this thing. The thing that surprised me the most was how responsive and smooth the braking is.
