25,000 Euro.....Nice bike.
Are the battery cells liquid cooled?
(The total enclosure will not allow for much heat dissapation).
And, hopefully a more affordable price when it hits the market!
It depends which parts they put in swingarm weight and which they counted as part of the rim/tire. I suspect bearings and mounting will be counted in the swingarm so their rim claim may be accurate as you have an aluminum hoop and a tire. Their unsprung mass on the other hand will be way up on a conventional setup.25,000 Euro.....
I call BS on their previous claim that the rear wheel is comparable to a regular rim/tire cobo for weight.
Agreed, the weight equivalency seems unlikely without the use of exotic (and expensive!) materials.25,000 Euro.....

Yes, the un-sprung weight that every other company spends buckets on to get the weight out of.It depends which parts they put in swingarm weight and which they counted as part of the rim/tire.

I dont know of any motorcycle burning dinosaurs that does 1000km on a single fillup. I’d settle for 300-400km on a charge.When an EV will go 1,000km on a charge and costs the same as a dino burner,i'll raise an eyebrow.But i'll be taking a dirtnap by then.Carry on.
True. But it will only take a few minutes to fill the tank 3 times. The available ev bikes can't even be considered for an ib as they are right now.I dont know of any motorcycle burning dinosaurs that does 1000km on a single fillup. I’d settle for 300-400km on a charge.
Point taken. Didn’t consider that.True. But it will only take a few minutes to fill the tank 3 times. The available ev bikes can't even be considered for an ib as they are right now.
A big issue with rapid charging is heat. Bikes have a relatively tiny battery and small cooling system. There are things that could improve the situation (water mist for rad, blast chiller for rad, etc) but given the tiny number of bikes that will want rapid charging, I suspect those solutions may be as rare as hydrogen filling stations.Point taken. Didn’t consider that.
I wonder if bikes can use super chargers or are the components too big to fit on a moto frame.
I'm in the wheel making biz, goofy stuff like that is done occasionally for industrial equipment.From their website "Unsprung mass is comparable to a conventional setup but rotational mass is considerably smaller. Tire changes easily done with conventional tools."
WTF? That seems very unlikely with this design. Maybe by comparable they mean "less than double". That bearing will be friggin heavy not to mention the metal motor windings. Similarly, with the outer bearing race that close to the perimeter rotational inertia should be much worse. It only makes sense if they are playing with unobtanium for marketing purposes like nanotube wiring and carbon races and have no intention of those surviving to the final vehicle (if it ever actual happens).
This is a hard one to guess at. I'm guessing the swingarm could be a lot simpler and lighter if it didn't need to keep the frame straight under heavy torque, with a hubless design there should be no twisting forces on the swingarm from the chain. Also, ev motors are approaching 5hp:lb power:weight, so you might get a pretty light motor in this setup. I doubt the unsprung on a hubless motorwheel could best a conventional rear setup -- but with the right materials maybe.It depends which parts they put in swingarm weight and which they counted as part of the rim/tire.

See post 23, the post that bumped this from 2019.pretty sure that's a CAD rendering. does it actually exist?
I'll buy that...but why is it hydraulic?
Cool. Where are you going to use this thing when you're done? Arent you making an uninsurable motorcycle?Why are you sure that it is hydraulic?
I'm currently doing an electric conversion and any motors with regen also have hall sensors to check the speed of the wheel against teh regen braking. Many diy conversions do away with the rear brake and just stick with regen. The second brake reservoir is likely just triggering a pressure transducer going to the motor controller.
The hub motors that I was having quoted actually came with two hall sensor cables because the sensors in the hub motors fail so frequently is was cheaper to just install a back-up on each motor. I've decided to go with a mid-drive motor.
It's a clean V-Star with a different (lower hp) motor. I'm not the first one to do it. Seems like guys in the UK have the most difficulty registering conversions.Cool. Where are you going to use this thing when you're done? Arent you making an uninsurable motorcycle?
