Other Notable E-bikes
Some other models I've looked at or helped people buy:
Specialized Turbo Vado SL ("Vado")
The Vado the "hybrid" (straight handlebars, but fast like a roadbike) version of my "Creo" electric roadbike (part of the Specialized "Turbo" ebike line discussed above). It has the same motor/battery system that I love from the Creo, and is also just an incredible machine. It has essentially all the speed/range/quality of the Creo, but you can put a rack and panniers on it and haul stuff / use it around a city a bit more easily.
My sister-in-law has a Vado 4.0 SL EQ, and my mother-in-law has a "step-through" version. I've been thinking about getting a Vado 5.0 SL EQ (newer model, has a couple nice features over the 4.0 (like the "Future Shock" handlebar suspension).
RadWagon
The RadWagon is a true cargo e-bike (as opposed to my Vektron Q9, which has less capacity and power, as a foldability tradeoff) for just $1900. RadPower is aggressively targeting a mainstream price point, seemingly mimicking Tern designs but with less premium components and a more mass-market focus.
This is a leading contender for my 5th e-bike, since I still have occasional cargo/hauling needs beyond what I can accomplish with my Q9, and it is so aggressively priced.
Gocycle
Gocycle make cool/sporty/design-y folding ebikes. They seemed a bit expensive and lacking in hauling capacity for what I needed when I demo'd them, but could be good commuter bikes.
Qualisports Dolphin
A friend recently got a Qualisports Dolphin; it seems like a good commuter bike: cheap ($1400), powerful, has a throttle.
Carbo Model X
The Carbo Model X had a huge crowdfund campaign, and the specs seem like the best of several worlds (folding, lightweight carbon, powerful motor, large battery; an e-folder that's 10lbs lighter than the Brompton, and more powerful).
I was able to test-ride one at Greenpath in Brooklyn; I felt like I might miss having multiple gears, and the carbon frame had some flex to it that I found a bit disconcerting. I've heard that low-quality carbon frames can fail in catastrophic ways, so I ultimately decided to let the "carbon e-folder" space mature / dust-settle for a bit before looking at it again. I had recently narrowly missed clicking "buy" on United City Bikes' "The One", which was a similar crowdfunded low-cost carbon e-folder, only to have them liquidate the company the next day ðŸ˜!
Things are moving fast in ebike-land, and there's something to be said for going with reputable brands and stores you can go to for service!
