You can read the details in the article above, as well as a few details I will tell you here.
I am a representative of EMGO TECHNOLOGY, my name is Alex and I am glad to be among such professionals as you!
We have created a powerful electric motorcycle in which we have implemented many features that are not available for most electric motorcycles in the price category up to 7000 EURO.
Our website: https://emgo.technology/scramper3-en/
Brief characteristics:
1) BLDC motor with a peak power of 16 kW (7200 RPM)
2) Fast onboard charging with support for 110-220VAC, as well as support for car charging stations TYPE 2 (Mennekes) (Full charge in 2-2.5 hours)
3) Powerful 10 kW Li-NCM battery with an innovative patented active air cooling system, thanks to which the battery is able to withstand a constant load of 24 kW for 30 minutes without cell degradation.
4) Maximum speed 127 km/h
5) Power reserve up to 200 km (at a speed of 45 km / h), P.S. let's be honest, we love speed, so we drive around 75-90 km/h, so the real margin will be about 160 km
For those who like to "squeeze all the juice" and drive at maximum speed - you can drive a guaranteed 100 km.

Suspension Test and off road test -
Charger and offroad test -
Engine:
The ScrAmper has an integrated power plant. BLDC - engine with a nominal power of 9 kW and a peak power of 16 kW (7200 RPM) and a 4-speed gearbox. The transmission works similarly to gasoline. The ability of the electric motor to reach a peak power of 16 kW and the ability of the battery to provide the engine with such energy and create a dynamic character ScrAmper.
Charger
The charger is integrated into the motorcycle, which provides a fairly high charging speed. And support for the car standard PLUG 2 (CCS 2) makes it possible to charge the motorcycle at car charging stations. At the same time, having only a charging cable with the socket with which the motorcycle is completed, you can charge the motorcycle simply at home from a household network (110 / 220V).
Battery - HD10 POWERPACK
The ScrAmper electric motorcycle battery has a patented innovative cooling system of HD10 Power Pack elements, which is at the same time simple and inexpensive. Thanks to it, having a nominal value of only 10 kW, the battery can operate in Heavy Duty mode, steadily giving 23-25 ??kW of power for 30 minutes. At the same time, the temperature in the middle of the battery will not rise above 38 ° C and will not reach the critical marks for the elements. Thus, the HD10 Power Pack includes not only the ability to super-return the battery, but also increase the battery speed by 2-3 times compared to the current parameters of ScrAmper.
This allows us to use our POWERPACK in other motorcycles with a more powerful engine in the future. Peak short-term battery power without degradation is 40 kW
Already in February, we are sending a motorcycle to Italy for European certification, and at the same time we are launching the Indiegogo crowdfunding platform to collect orders and resources to start production in Ukraine. I will update the information and add a link here to the crowdfunding platform so that if you are interested, you can order it.
To certify a motorcycle for the American market, we need at least 300 orders around the world, so we will really hope for you and your support in social networks and other resources.![]()
Thank you all for your attention, wait for updates, and we will also be glad to hear your opinion about the product.
In view of current events in Ukraine, this is an interesting electric motorcycle (complete with a gearbox) startup request for crowdfunding article:

that sales pitch *confused*thanks for sharing, I guess? technical discussion always welcome.
Since it has a "normal" size rear sprocket chances are it is a reduction gear type of motorcycle. How much noise is from the reduction gear, the chain, the tire, or that aparatus it is tied to is not really known.
A powerful motorcycle should not be heard by the operator or passenger at speeds over 50 mph at least for a standard set up with an upright rider. I guess with a fairing or body work to hide behind things are different.
The whole thing of the exhaust sound, noise if you will and how it effects the mental state of the operator and hence how hard the throtle is twisted certainly can vary from bike a to bike b.

My comments come from my experience with the first electric motorcycle that I bought in 2009. It was a Electric Motorsport GPR-S, bolted together in Oakland, California. It was an interesting and easy to assemble design that used a chassis made by Tiger in Thailand, which arrived at their "factory" fully assembled, including battery boxes. EMS was an electronics supply company and had a lot of parts on their shelves. They had a small team of workers who attached an electric motor, installed 20 or 24 Chinese-made High Power brand lithium block batteries, added an off-the-shelf fork lift controller and a locally manufactured BMS on an open circuit board to the chassis. The bikes sold for $8,300 USD. Top speed was around 65 mph and the range was about 20 miles on the highway or 40 miles at 30 mph - when the batteries were new.
It all worked pretty well for a while, but did have a few weak links. Such as the batteries couldn't handle the motor's electric power demands and would start dying after a short while. Sometimes the BMS or charging system would overload and fail and when you went back to the company they didn't really want to deal with warranty issues - especially when their DMV retail permit expired and they forgot to renew it. Finally, they changed their brand name to Native and started selling their bikes out of small electric bicycle retailers. But the warranty complaints continued, which they tossed back to their retailers. As the warranty work continued to pile up, the retail outlets were overwhelmed and the shop that I dealt with went out of business during the fall of 2010. Not long after that, the brand faded away and the company went back to selling electronic parts.
It really wasn't a bad design for the times, but the battery selection was completely wrong and the EMS just didn't seem to have the necessary knowledgeable vehicle marketing staff and engineers. Plus they appeared unwilling to invest sufficient funds in their company to continue development of their motorcycles and to back up their retail outlets. If they had stuck with it, developed a better product and actually established a good marketing system, they might still be in business today. But they didn't. (I don't believe that they were ever able to sign up an established motorcycle shop as a retail outlet. They dealt with small mom-and-pop brick and mortar shops.)
While this story has nothing to do with your company, or with the current state of the two-wheel EV market, I just thought I would mention my early experience with the electric motorcycle industry as a consumer. My first GPR-S lasted 300 miles before the charger caught on fire in my garage. Then I bought a 2010 model with a golf cart brushed motor and on that one the batteries started puffing up at 1300 miles. Fortunately, Zero arrived on the scene at my local Japanese-brand motorcycle shop and i ended up buying a 2012 Zero, which was a huge improvement over the EMS models. I have stuck with Zero ever since and have been satisfied with their products.
Anyway, from a customer's perspective, product support and customer service are the things that we really appreciate.
Attached is a photo of my first 2009 GPR-S.
It is great to see an electric motorcycle being produced in Ukraine and not China. I wish you the best outcome to your venture.
But as you likely already know, designing and building any vehicle is easy compared with setting up a manufacturing plant, retail outlets, distribution and parts supply network, servicing schools, getting government type approvals and other similar things that need to eventually be accomplished to grow and establish a vehicle manufacturing business that can actually make a profit in the long run are the really tough things to do. Designing the vehicle is the easy part of the job.
?mistakes, salaries of people, sleepless nights, nerves and much more.I totally understand that in reality no one would be charging from 0%, it's just standard practice to give the 0-100% charge time and if you're talking about a shorter charge it needs to be clarified. For example your site says 100% - 100 minutes which implies 0-100%, and then 80% - 60 minutes would mean 0-80%. Like wise your original post said a full charge in 1.5-2 hours, I know that English won't be your first language but to me I would take "full charge" to mean 0-100%. What you really meant is charging "to full", from say 20% for example.
It's good that the majority of production is happening in Ukraine, I assumed so and that's part of what makes me think costs will be higher but I'll admit I have no idea how much more expensive it would be compared to having it all made in China.
For the charger I was going off the 100 minutes to 100% stated on your website, which would require roughly 6kW for a 10kW/h battery. With a 3.6kW charger that's going to be roughly 3 hours (2.7 hours at constant power but of course it will taper off at the end) so not even the 2 hours stated in your original post. Still quite good though and better than what Zero can manage in their base level bikes.Sounds very impressive (the gearbox is a little disappointing, I'm guessing the motor is fairly low torque). How confident that you'll actually be able to deliver the bike at a cost of $6k? That doesn't sound very believable, like a 6kW charger alone is approaching $2k and the battery would probably take up the remaining $4k quite easily. For example a 7.2kW/h Zero with a much lower power charger is double the cost.
Thanks for your feedback. In fact, the price of 6000 USD was indicative, after we moved production to Ukraine, the price changed slightly. In retail, it will cost about 7000 EUR.
Charging power is 3.6 kW, not 6 kW.
In fact, how did we manage to invest in this price (This price is also beneficial for us) - Zero motorcycle uses a lot of expensive plastic molds, as well as expensive components + a lot of resources are spent on marketing, publications and other promotions, and of course the staff who have good salaries. All this affects the price very much.
We tried to make the bike easier, we were at an exhibition in Milan - and gathered crowds of satisfied spectators who liked both the design and the overall picture.
We wanted to create something powerful and good for people who dream but cannot afford something expensive. Everyone should have the right and opportunity to enjoy good things.
Also, if you place an order through Indiegogo, the special cost for each person will be 5500 EUR when ordering 1 unit.
I still feel like €7000 (nearly $8k) is highly optimistic though. While Zero does use some more expensive higher end components (suspension and brakes mainly) your bike doesn't look much cheaper in comparison, you've still got unique body panels and frame and all those metal plates and the motor and battery are still going to have a significant cost. On top of that I'm guessing you don't have the same economy of scale that Zero does. Where is the bike manufactured and assembled?
Looks like a nice package, with good onboard charging options. The price is real impressive and hope it can be delivered and supported at that target.
What is the weight?
Is that a clutch lever on top of the motor-gearbox unit?
Peak power is at 7200 rpm. Where is the point that the torque drops off. Generally, these motors make torque at close to max until a point where power stays the same as rpm goes up and torque goes down. What is the motor rpm max and what is the overall gearing like? It looks like you have a sensible sized front sprocket from the angles of the chain. I see the transmission ratios would be close ratio for a street bike, probably about the same for a track oriented off road bike.
How about the weight distribution? Looks to me to be heavy on the front wheel.
What is in that part of the bike closest to the ground.
Good luch with the launch. I am kind of concerned with how the knees and ankles contact parts of the bike not going to be pre ordering and encouraging that business model.
