I have a Boosted[1]. There's a lot of competition but when you look at specs, they don't really quite make it. They're either slower, or can't do hills, or take longer to charge. Build quality on Boosteds is amazing as well. Thing's build like a tank.

With my usage pattern (commute to gym and back 4 times a week), it pays for itself every 4 months.

And yes, it gets me there faster than a bike or using public transit. Even Uber is just 3 minutes faster (on a 15min trip) because of traffic.

[1] I actually have two. If anyone wants to buy my old Gen1 for half price, ping me.
