1. Plastic chain guard cracked/disintegrated within first few hours of use. Have gotten pants leg caught in chain once, not a big issue for me. Very easy to break off and get rid of part when it fails, which it will. Believe I could put a good one on if I wanted to. Note that they responded to my initial review and say they upgraded the chain guard.
2. Included front fender is kinda cheap looking. It will last and has a cool shape though, so you might like it. Regardless it has sketchy hardware and loose attachment. The "Euro" fenders listed on Amazon fit on it no problem though, though in my case I partially mounted the front one onto the rack. Mounting their fender to a rack would probably make it functional and worth keeping. They say the fender is a freebie in their response to my first review, but with a front suspension fork I don't really know of a way to get a fender to mount securely, and their hardware sure doesn't.
3. Rear clip 'rack' of limited/no utility (great for carrying a newspaper other than if it rains?), BUT, an ordinary cheap wire basket (looks nice if you get one with black wire coating) can be securely attached to their rack with black cable ties (available in military spec if you're really serious about it). Carrying larger loads would make the bike top-heavy in the rear with this setup. Note they say they (now?) offer two rear rack options, which I may take them up on.
4. Have installed a front rack from Amazon, albeit with some creative cable-tying (military spec a really good idea here) for the upper connection. Not sure where to find a front rack to install as intended with a front suspension fork, if anywhere. Note you could put a basket on top of the front rack I picked.

The R10 is excellent on a number of levels:
The Lithium Polymer battery has revolutionized electric model airplanes because of its very high power to weight ratio and lifetime, and it sure works well here. The motor drives the chain at the chainring, so it can use the 8 gears, and puts almost all the added weight down low, so it feels like a regular bike when riding. The pedal assist really works, with off, low, medium and high settings easily made. As a result, I don't us the throttle at all. The front and rear disc brakes are smooth and powerful, and shut the motor off when applied, which is important when the bike weighs 60#.
It does have some downsides:
It should have a key lock to disconnect the battery, but you have to unplug it at the battery, which is annoyingly difficult. The suspension is very stiff, but that does mean you can use the front brake without causing the front suspension to dip excessively. The rear rack is somewhat of a joke, but it already carries the full weight of the battery, so probably better not to add much more.

Going to the Post Office (sidewalks, driveways and Cars), pedal assist Off is the choice.
Riding on a dirt road, with soft spots , humps and hollows, into a 25 mph headwind, was an eye-opener. Normally I would be huffing and puffing and trying to stay low out of the wind. With pedal assist Medium, I pedalled along easily like there was no wind at all. Totally amazing!
Riding on a paved road with about a 2% uphill grade, using pedal assist High, I pedalled along like it was slightly downhill, while going faster than I ever could normally. Another total amazement.
I love this bike, but follow their advice and get 2 people to assemble it. I didn't, and handling a 60# bike by yourself will provide some interesting moments!
Finally, with the stiff suspension and weight, this bike is not for off-road at all, but it eats up paved roads and decent dirt roads.
