2/27/2023 Update: I've been commuting on this all winter, but not every day. I'm at about 460 miles. Just bought a Aventon Level2 and am putting this one up for sale. I noticed they lowered the price on Amazon; (see below) that's refreshing. I think they realized that pricing this so far over the higher-quality Lectric was not going to work for long.
The brakes still squeak, but I'm used to it now. The Brooks B67 saddle and a milk crate zip-tied to the rack made this perfect for commuting duty. (except for being pretty inefficient on pavement, due to the heavy 20 psi tires) I didn't use motor all the time and mostly kept it to either 9 or 13 mph assisted. No reliability problems. No noticeable wear in this amount of miles, even the tires. I did some pretty heavy shopping trips on this on the way home from work. Filled my big business backpack and the milk crate. Would've been a bad ride on an purely mechanical bike.
One thing worth noting is that the included seat post is not long enough for tall people. I'm 5'8 and have a 30" inseam and I cannot quite get full leg extension, though it's close.
Original Review: These are available on Amazon for$1400 $1100 US. Currently, there's a $70 coupon, which pays for the $30 FedEx Ground shipping from California and a bit toward the sales tax. I bought with my Amazon Prime VISA card to split it into 18 equal payments with no interest.

Basic specs:
I'm going to look a little and see what tools I'd need to change an inner tube on the roadside and order a spare. I have a feeling it's going to be complex, for the rear...
The thing that surprised me so far is that when I pedal at all, the motor kicks in to take me right to the top speed of the PAS, rather than providing a boost proportional to my effort. Someone posted an FAQ video that explained this type of system. It uses a hall effect sensor instead of a torque sensor, like the fancy Trek e-bikes.
Also, I wish I had thought to look up this bike's weight. 71 lbs. is too heavy to reasonably and regularly be loaded into a car or to take along on mass transit. I may end up buying a smaller, less expensive e-bike later for that purpose, but I'm going to enjoy this one for awhile.

Best Electric Bikes for Adults| Heybike Ebikes for Sale
Heybike sells the best electric bicycles online. Shop powerful pedal-assist ebikes for sale. Have a look and find a long-range electric bike for adults.

Basic specs:
- 500 W planetary geared hub motor
- +/- Foldable, but it's a 71 lb. bike;
- not reasonable for one person (except bodybuilders) to load it in a sedan. Maybe a hatchback. Watch the weather stripping
- Not a good model to take on public transit
- +/- Fat tire-type; it's a bit noisy, but will truly handle almost any terrain (extremely rocky might not be good) However, these contribute to making the bike quite heavy.
- + Comes with three assist levels, but with instructions to re-program for 7. It really should come programmed from the factory for 7, as the lowest PAS takes me right to 13 mph. PAS 2 = 19 mph, PAS 3 = 24 mph. I'm finding that sometimes PAS1 is too fast; I would like settings for maybe 7 and 10 mph below it. PAS3 is a bit too fast for the highest gear, so that I can actually keep up and go faster than 25 mph if I want. That will give me a proper cardio workout. I plan to re-program this speed setting to PAS7, and have a few intermediate settings. HeyBike makes some recommendations in their literature.
- + Assembly is not too bad, only unclear thing in the instructions are where the washers go for the front wheel. Instructions say it goes "inside", but really it goes outside the safety hook washer. (otherwise the brake disc doesn't line up with the caliper)
- When mounting the front wheel, invert the bike on a soft surface, like cardboard or grass, so you don't scratch the paint on the rack. They don't tell you this, but if you don't do this, it is quite frustrating to get the front wheel mounted. If you DO invert it, it is quite easy and just takes a bit of patience.
- + Includes sturdy rear luggage rack, fenders, full lighting. In the product images, the rack seems to be integral to the frame, but it is actually bolted on. A frame-mounted front rack is available as an option, as are panniers. A spare battery (48 V, 15 Ah) is $500.
- + I read a lot of reviews, and while this is a smaller Chinese brand, their customer service gets good marks. That's why it is $200 more than competing models from lesser brands.
- - There are some miscellaneous squeaks, especially from the mechanical disc front brake
- - The included tools are not TOTAL garbage, but the 14 mm combination wrench was too small for the 14 mm nuts. Other hex wrenches (open end only) were OK. The allen wrenches are chrome plated and fit the allen heads well.
- + The front headlight is powerful enough to be useful, and is easily aimed while out and about with just a #2 Phillips screwdriver.
- + When the lights are toggled on, the rear light is on solid, and when the brakes are squeezed, it blinks rapidly. This is a nice touch. I feel pretty safe, as my Schwinn helmet from Amazon has a built-in rear light too.
- + Mag wheels = no spoke hassles, ever. This is the main reason I bought this bike over the older Mars model with spokes.
