I've had this bike for a few weeks now. Here are the pluses and minuses. Only reason I didn't give it 5 stars is because the - below. Very happy with it over all.

+ very sturdy
+ very powerful
+ carries me well. (400lbs)
+ quality build
+ looks nice

- batt doesn't last as long as it says. ( 28 miles for me) that may be due to my weight

I received the bike on my 65th birthday but I turned 9 years old instead.  I have 350 miles on it now in about a month and a half.  I CAN PEDAL THE BIKE FINE WITHOUT THE BATTERY.  I need both hands to ride it.  I can take one hand off but it is a little squirrely.  Each time you pedal the front wheel turns a little to the opposite side.  Its a pretty light front end.  Not a game changer though, not at all.  I ride this thing everywhere.  Deep sand, any size gravel, and grass fields are not an issue at all.  I have not pushed it to see the battery or power limits.  I have taken it up steep hills for several blocks.  It went up just fine.  I think a prolonged steep climb would be for a different bike.  What is this range anxiety they talk about????  I have a long bike trail by my house (31 miles).  I went 15 miles down turned around and came back.  The last 7-8 miles are uphill.  When I got home I still had 3/4 of a tank/battery but I was really weary/tired of riding (sitting).  Unless your commuting I wouldn't worry about range.    

I use E-speed 1 or 2.  I use pedal gear 3.  I try to keep the battery from coming on by pedaling so exercise is there if you want it.  I use higher speeds only when I get bored or tired and want to get where I'm going.  I use speed 5 and the hand throttle pretty much only to get across the street or a bridge where I dont want to dally in traffic. (I can cross the street quicker than I can get the pedal down one time)

A boy, maybe 14, on a single speed stingray bike challenged me to a race. I clicked it to speed 5 started pedaling and only then shouted "Lets Go" I was going 21.5mph a couple blocks later and he passed me!!  Ha HA! Yes get one of these, its the fountain of youth!  Can't wait until I'm 10, I'll beat that kid then!

This is the third e-bike I have purchased on Addmotor. Two from this seller (Addmotor) and one is a Wallke. (See photos.) Overall, this seems like a great bike although I have not ridden it much yet. I will try to update once I hit some hills, although I have another Addmotor bike (see photo) that powers up steep hills quite easily.) That said, the instructions with this bike are frustratingly bad. Here is what you need to know:
(1) Seat is super comfortable. Can easily hold two bodies and has passenger foot pegs (but the backrest does NOT come with it).
(2) Speed is super fast. Great pick up. Has 5 levels.
(3) My wife is 5'3". I bought this one because the Wallke (green one in photo) seemed a bit tall for her and is hard for her to put her feet down. This one says that it is for a person as short as 5'2". In my opinion, this is barely a good size for my wife. It fits her but I would not get one for someone shorter. (FYI, the black and orange one in photo is also from Addmotor and it fits me and people taller than me. I am 5'11". The black and orange one is not for shorter people in my opinion.)
(4) It looks super cool. Red, white, and blue. Unique color and look for a bike. (See photo)
(5) Instructions are bad. Here is what you should know about assembly: FRONT WHEEL- The axle is the long black pin/screw that came in the box. (Not the silver screw that is only there during shipping and then discarded.) The large black spacers come in two sizes. The smaller one goes on the side where the brake is. From outside in, it will end up like this on each side: Nut, silver washer, fork, black spacer. HANDLEBAR: Instructions say, "Remove the two caps." I have no idea which 2 caps are being referred to. Just take the top cap off the fork mount (the pipe coming out of the top of where the front wheel is) and set it aside. You don't need it or the screw that held it down. Then remove the 2 screws that are in the side of the handlebar mounting pipe so it is loose enough to slip over the top of the fork mount. You may need to flip up the latch on the bar (by pressing the side button) to give you some wiggle room. When you try to slip the handlebar over the lower shaft, you need to align the upper screw with the hole below. Wiggle it or put the allen wrench on the top screw to manipulate it. Then push down. It will go down quite a way before you have to tighten the screw. Tighten well. FENDER AND FRONT LIGHT: Install these at the same time since they use the same screws so you don't have to re-do it (like I did).

I bought the M60-R7. I admit I was skeptical at first. But then after riding it for two weeks now I’m glad I bought this ebike. It’s a comfortable ride and it’s built well. The power and controls are legit. My only con about it is that I wish it can go more than 20mph as the top speed on the throttle. But other than that It’s definitely an attention getter and people have asked me if it’s a mini motorcycle. Haha
