    Grom clones were available in Taiwan about a month after the Grom came out.

    Clever the way they mounted the controller to look like an exhaust.
    I don't think its possible to buy the motor, batteries and controller alone for $1599 if the specs listed in the post are correct.

    It will be interesting to see if it meets the speed/distance claims. We have had a couple small electric scooters to use around RV parks, and they were great. Those weren't street legal, so this one has a LOT going for it, if it does what it says.

    Hope the batteries don't catch fire while you are riding it like those hover board clones all the kids got for Christmas. Other than fear of a firey death, it looks really cool.

    I don't see how they can get those performance numbers for that price either. Some time ago, I tried to find (or build) an electric bicycle with a 20 mile no pedal range, and all I needed was a top speed of 10 mph. I discovered it was going to cost between $2000-$3000 to do that. And that was for a bicycle with skinny tires and a lot less weight than that fake Grom.

    2000 watt motor, about what a 49cc makes, 60 mph?

    NO WAY, that Is total BS !!!! The real GROM has 8 - 9 HP and 60 MPH is its absolute top speed stock. 2000 watts will NOT go that fast.

    Also, I don't believe it is even 2000 watts, most cheap Chinese products LIE about their specs. The gas model will probably break down the first month. If you want a GROM, buy a real Honda GROM. Unless you want to spend 1500 dollars and have a broken bike to look at, that you can not get any parts for.

    If those specs were anywhere close to correct, I'd buy one. I have a hunch though that 45 MPH top with 40-50 miles of range would be closer. 10 cents per charge is optimistic too.

    I don't believe for a minute that it will go that fast, or even that far for that price, not even close.... I hope we get an accurate report of what it does when someone buys one.

    I'm going to jump on the naysayer bandwagon. 2000W is not even 3hp. Stock Grom will barely pull 60 on flat ground with 10ish HP.

    I got one, I purchased it from a dealer in Sacramento. It was the first time they sold this bike, though they deal in other non-electric products.

    Here's my 2 cents on the bike, since I took the plunge and there isn't much on the net about these things.

    I weigh ~280 lbs with all my gear, so I'm near the indicated limits of the bike's capacity 330 lbs if I remember correctly (ref: Boom International Holdings website, USA, look it up).
    For what it's worth that mfgr. states top speed is actually 65 km/h, again see their website.
    Per the manual, as I've been conditioning the battery through use, 61 km/h is the maximum indicated speed I have achieved, I started with a 58 km/h top speed at delivery (4km on the bike) and the top speed has climbed.
    Everything looks nice and fits together well, I like the bike and it's cosmetically a value, with tinted signals and even signals frenched into the fairing.
    Some non-important welds are obvious crap, like a nut that holds a fastener to mount a body panel on the battery box.
    An indicated 12-15 km is my range on the new battery array, I drove it 12 km home from the shop, and it was dying as I came around the corner to my home. I don't push it any more because I don't have to and don't want to. If you've got a rolling road, I'd be happy to test it. The only true disappointment, as the mfgr. states the range is 55-60 km.
    Indicated speed and range seems accurate, the odometer is tied to the speed of the rear wheel.
    I can't 1 up it (not a chance), but it is torquey. Maybe if it had a clutch... but it is a 1-speed automatic, the motor is in the wheel.
    You can't apply the front brake and the throttle to do a burn out :(
    You can do a burn out on a slippery surface :)
    Throttle can be a bit touchy, but it is certainly adaptable to once you understand how it applies the torque.
    I changed the headlights out to LEDs and they are great!
    It requires a motorcycle endorsement in my state, California.
    To save on range, you can turn on the lights in 4 states: all off, red-leds (not bright) parking, + lights, + brights
    A full charge takes ~6 hours.

    WARNING: If you drive the thing heavy down pour, with water all over the road, the bike may have issues, but my experience was relatively safe (it was a no-start condition after running, it actually ran fine in the rain).
    My experience: I pulled over to get something at a gas station during a heavy downpour on my commute, as a result the bike would not engage power to drive the rear wheels for a couple of days, the gauges and lights engaged just fine. I checked the breaker and cycled it, I charged the battery, and I couldn't get the bike to move until it dried out in a couple of days (my guessing). -- Everything has been great since, and today I just rolled over 100 km on the odo (~62 miles).

    I hope this has been helpful. Ask any questions if you have them.

    Sounds very interesting, and despite what all the dino-fuel lovers say, it IS the future.

    Instant on acceleration helps, and if you want to be truly "green", go to Tractor Supply and buy a their solar panel kit.

    Lithium battery fires can go "BOOM".

    True, but Tesla is doing pretty well with 'em.

    7-9 miles on a charge is less than half what a typical golf cart will do.

    Hard to think of any practical use for it. Electric bicycles seem like a much better option, at least for any situation that I can think of. At least with a bike you can pedal if you run short of your destination or use pedal assist to extend the range.

    I think electric IS probably our future, but the future ain't here yet.

    I haven't tried the e-bike with just the throttle to see how far it will go. At 18 miles with pedal assist, the battery is generally flickering between 3/4 and 1/2. Of course, I can only go about 20 mph on that bicycle.

    My perspective is: an electric scooter is more practical than most pure electric cars. 18 years ago, I had a small electric scooter (not street legal, but great around the campground) that had about an 18 mile range. I would think they would have improved a whole bunch since then. With a 40 to 50 mile range, these would be great as an errand runner.

    It sure won't replace my scooter, but the e-bike has been all I hoped it would be. Yeah, I think electric is our future, too.
