Milandr takes rider through waist-deep water
This seems pretty remarkable to anyone who knows only ICE propulsion. But really, any EM drivetrain is fairly easy to design in a way so it meets IP67 or IP68 standards (immersion at under or over 1 meter depth, respectively). It's all that air breathing an ICE does that makes it difficult for them. Put SCUBA gear on the rider and he could ride his EM as a submarine.
This will become commonplace, at least for dirt EMs. We're not officially there yet, but it's inevitable. Dropping your bike in a creek will no longer mean a long walk home and a tear-down. Much deeper water crossings will become possible. Start getting used to the new normal.
You say "as a submarine" but I definitely heard "On Mars" and I approve this message.
It’s official: NIU to open US sales for seated electric scooters now!
The company will officially launch sales and test drives at 12 US retail locations on December 1. Dozens more locations are expected to open soon.
The information was just confirmed by NIU’s CEO Yan Li in the Q3 earnings call minutes ago.
The move marks NIU’s first entry into the US retail market, though its scooters have already been cruising US streets for months as part of the Revel electric scooter-sharing program in New York City, Washington, D.C., and Austin.
Three models of NIU’s scooters will be available in the US at launch, including the 43.5 mph (70 km/h) NIU NGT, as well as the 30 mph (48 km/h) NIU NSport and NIU M+Sport.
The M+Sport has a 1.4 kW Bosch hub motor and a single battery with a 2 kWh capacity. The scooter has an estimated range of 50 miles (80 km) at 28 mph (45 km/h) and 60 miles (100 km) at 15 mph (25 km/h).
The N Sport uses a different frame and body, making it a slightly larger scooter (though both the M-series and N-series scooters can support two riders). The N Sport has a larger 3 kW Bosch hub motor and a slightly larger 2.1 kWh battery. It is limited to similar speeds as the M+ Sport and comes with a similar range as well.
The NGT is equipped with a 3 kW Bosch hub motor and two 2.1 kWh removable batteries. The Panasonic-based batteries are capable of providing over 60 miles (100 km) of range. When placed in E-Save mode (the NGT’s equivalent of ECO mode), the scooter has a maximum estimated range of over 105 miles (170 km).
The 13 dealers taking part in the launch of NIU’s US retail sales are:
San Diego: Vespa Motorsport
Portland, OR: Vespa Portland
Seattle: Seattle Cycle Center
Denver: Sportique Scooter
Overland Park, KS: Scooter World
Chicago: Scooterworks Chicago
Atlanta: Twist ‘n’ Scoot
College Park, MA: College Scooters
Philadelphia: Philadelphia Scooters
Brooklyn, NY: Brooklyn Mayd
Vernon, CT: Connecticut Scooter Pros
Exeter, NH: EZ Bikes and Scooters
If you live near Montreal, you’ll be able to find NIU’s first Canadian dealer, Dyad.
Not all dealers will have all three of NIU’s US models available, so you should contact your local dealer to see which models they will initially carry.
An representative at EICMA 2019 indicated that NIU hopes to have 50 retail locations across the US by the end of 2020, including multiple NIU-only dealerships.
EICMA 2019 also saw the unveiling of upgraded versions of each of these scooters. The new models are the NQi GTs, MQi GTs, UQi GT, and the EB-01 electric bicycle. The EB-01 takes advantage of a number of NIU’s electric scooter developments, such as the company’s lighting, batteries, and detailed display. These components are integrated with a pedal drivetrain to create a 28 mph (45 km/h) electric bicycle that offers the comfort and ride experience of a seated scooter.
These new models won’t be immediately available in the US, though we expect to see them stateside sometime early next year.
Good looking scooter, good range, good price.
Pricing & availability in US confirmed
2020 NIU M+ Sport – $2,699
2020 NIU N Sport – $2,899
2020 NIU NGT – $4,599
I'm pretty sure most boat motors have bearings on the propeller shafts that work while fully submerged, and that last for years.
Yes, but, they have seals designed to keep water out. The seals on motorcycles are designed to keep oil/grease in, and dust out, but, not necessarily designed to be submerged in water.
New BMW electric patent:
Now we're talkin'! EMs are different, so we need to stop making them like ICEMs. The C Evolution from which this concept borrows heavily is a terrifically engineered piece, in large part because BMW threw out what they knew about packaging ICEMs, started with a clean sheet and designed for an EM's requirements. Monocoque construction makes a huge amount of sense thanks to the big, blocky battery pack, and the walls of a big aluminum box can easily have heat sinks cast in, or water cooling ports if you wish, for the pack and controller.
Keep in mind that this is still valid for a DIY approach. In fact you don't even need to know how to weld. Sheet aluminum can be bonded just as reliably with adhesives and rivets - even better, since you don't lose temper in heat-affected zones. Here are some monocoque examples that would be easy to adapt into a sweet EM. Basically make a box with an open top to drop the battery in, and cover it with a stressed panel.
Or just scale this up a bit:
All in all I think monocoque construction, either cast in high volumes or bonded/riveted sheet for one-offs, is a good idea for ICEMs and a terrific idea for EMs. When you think about actually doing it, making your own is really not that hard. Want an EM? Build it! All the power parts are available off the shelf. And done right you can end up with an EM lighter than an equivalent OEM bike.
Just can't think why they using bicycle brakes in such type of vehicles. Following is a prototype with much more robust technical solutions:
- Central Motor with reduction
- Nominal power 3 kW, owing to heat sink compound made to produce 15 kW constant duty
- Battery 20S 58 Ah, NMC, current 150 A, can also be set to 200 A
- Phase current - 370 A
- Sine wave trapezoidal air cooled controller, BMS
- Reverse motion
- Steel tubular frame, elongated swingarm
- Rear suspension DNM shock, 240 mm travel, spring rate 750
- Strong adjustable recuperation eleminates need in rear brake
- Two pos motorcycle handle bar -- adv or cafe racer
- Motorcycle brake disc and 2 piston caliper
- Motorcycle fork
- LED car headlight with clear-cut beam, lower/upper switch
- Rear steel sprocket 60, top speed 120 km/h or 72 teeth, dynamics of 400 cc road bike..
Have any of you guys following this thread seen a independent test of the new Segway eDirt bike? So far my searches have come up empty.
It appears to be a rebadged Sur-Ron
Damon Motorcycles is making electric motorcycles safer and more comfortable
Micah Toll - Dec. 3rd 2019 6:00 am ET
Vancouver-based startup Damon Motorcycles has set out to create the future of motorcycling. The company’s goal is to improve both the safety and comfort of motorcycling. And they’re doing it with their own in-house-designed Hypersport Pro electric motorcycle.
As much fun as motorcycles are, no one can claim that they are without specific threats and dangers inherent to two-wheeled vehicles.
And yet as technology has brought a myriad of driver assistances and safety features to cars over the last few years, motorcycles have largely remained unaugmented.
Until now, that is.
Damon Motorcycles Hypersport Pro
Damon Motorcycles is changing that with its new Hypersport Pro electric motorcycle.
The company has spent the past three years developing a suite of advanced safety features known as CoPilot. The CoPilot system uses a number of sensors including radar, multiple cameras, non-visual sensors, and AI to track the speed and direction of up to 64 moving objects around the bike at any time. The system uses a patent-pending system of haptic feedback vibrations in the handlebars and LED warning lights on the edges of the windscreen to provide riders with collision-warning alerts. CoPilot monitors 360 degrees around the bike, effectively creating a bird’s eye view of threats.
The system is designed to feel intuitive to the rider so that it increases the rider’s awareness without requiring an additional focus point.
But the Hypersport Pro isn’t just about improving the safety of motorcycles, it’s also about improving comfort. And to do this, Damon has developed a fascinating shape-shifting design for the bike known simply as Shift. Since the beginning of motorcycling, riders have had to choose the single type of geometry they wanted in a bike, such as an aggressively forward tucked sport bike or an upright cruiser bike, which has always come with drawbacks. As Damon’s CEO Jay Giraud explained to Electrek:
Sport bikes are great when you’re out on the highway, but they don’t perform as well in cities. On the other hand, an upright cruiser is great for the city, but then it turns you into a giant sail when you’re on the highway.
Instead of locking riders into a single geometry, the Hypersport Pro electric motorcycle’s Shift system is actually designed with adjustable geometry that can change and adapt to riding conditions on the fly. Riders can literally just push a button to set in motion the bike’s windscreen, seat, foot pegs and handlebars, all of which will move in unison to different presets. The options can provide seating positions that range from a fast supersport motorcycle to a sport touring bike to a full upright commuter. It’s the equivalent to owning multiple styles of motorcycles that you can hop between in the middle of a ride.
To develop this entirely new type of electric motorcycle, Damon has been quickly expanding its team. And one of the company’s most high-profile hires lately has been Derek Dorresteyn, who has joined as Damon Motorcycles’ new COO and also heads up powertrain development. Derek knows a thing or two about high-performance motorcycles. Not only is he a third-generation motorcycle racer, but he previously served as Alta’s CTO where he led the engineering and manufacturing teams for a decade and helped contribute to Alta’s dominance over conventional gas-powered motorcycles.
And considering that Damon Motorcycles isn’t just developing its innovative CoPilot and Shift systems alone, but is also creating an entirely new powertrain, Derek definitely has his work cut out for him.
Damon will be debuting its new Hypersport Pro electric motorcycle featuring its CoPilot and Shift technologies at CES 2020, and we look forward to getting a closer look at the innovative new e-bike then. The company is close to announcing tech/performance specs for the Hypersport Pro as well, which we are eagerly awaiting.
From a recent submission in the Honda CB300R discussion thread:
Rieju Nuuk electric, 68 mph top speed, up to 173 mile range. Reiju has a range of electric bicycles too.
So seemingly excellent; so apparently unavailable in the US. Would be a perfect commuter for my purposes during this moment in time. Very much into their styling on that model as well, and I'm not typically drawn to scoots/mopeds. Can't place my finger on why I find that particular example so appealing, but I do.
Any one know more about Rieju's build quality, service, etc etc? The company appears to be based in Spain?
Like that tracker a whole lot, even range is pretty good it seems. And the weight is really low so great for off road exploring. Nice!
looks like a very useful urban commuter and utility bike. Pit bike, grocery getter, scrambler, dirt road explorer perhaps.
I think there's a huge market for such bikes, particularly in congested areas and developing countries, for basic transportation. I think there have been more Honda Cub bikes made and sold than any other machine- car or bike. I think the Chinese will be able to produce such bikes far cheaper than anyone else, but there are some good design elements here. Needs a milk crate.
I like it but it needs a RED milk crate.
Tesla to launch Cyberquad electric ATV in late 2021, hints at possible dirt bike
Fred Lambert - Dec. 8th 2019 10:50 am ET
“At the end of the Cybertruck unveiling last month, Tesla brought on stage an electric ATV made by its design team.
The vehicle, called Tesla Cyberquad, was used to demonstrate the loading capacity of the Cybertruck, which can lower its rear suspension to accommodate easier loading of a vehicle on a ramp to the bed of electric pickup truck.
It plugged into the electrical outlets (110v/220v) onboard the Tesla Cybertruck — meaning that while the Tesla electric ATV is on the Cybertruck, it is charging.
At the time, Musk didn’t mention anything about making the ATV available at the time, but he later confirmed that it will be an option for Cybertruck buyers.
Now the CEO confirmed the timing.”
Tesla is aiming to have its electric ATV by late 2021 – like the Cybertruck (via Twitter):
“We’ll aim to have it come out same time as truck. Two-seater electric ATV designed to work with Cybertruck will be fun!”
Furthermore, Musk said that it “would be cool” to also have an electric dirt bike as an option for the Cybertruck
“Electric dirt bikes would be cool too.”
However, the CEO reiterated that Tesla will never do an electric motorcycle for the road because he believes them to be too dangerous based on his own experience:
“We won’t do road bikes, as too dangerous. I was hit by a truck & almost died on one when I was 17.”
The Tesla Cyberquad is now expected to be released in late 2021 as an option for Cybertruck buyers:
.. Tesla dirt bike? Yes, I’ll take two please!
Just don't clip that sharp corner over the rear wheels of you happen to crash.
Did he call it Vlad?
I get the design language, but razor sharp points and atv's should probably not be mixed, lololol.
Otherwise, kinda cool.
