Erik's new venture: https://fuell.us/ | ||
| Crusty |
A lot cheaper than the Live Wire and probably a lot more innovative, if Erik's involved. | ||
| Court |
I was waiting to see who would pick up on the announcement . . . :-) | ||
| Oldfartnbuell |
Oh please Great One, let me live to see this come to market! | ||
| Froggy |
So are they going to have quarterly newsletters called Buell? | ||
| Jaimec |
I have my doubts about that hub-mounted motor... it seems to be the anti-thesis to Erik's "Trilogy of Tech" but we'll see what happens... | ||
| Ourdee |
It is the hub, the brake, the motor. Eliminates sprocket/pulleys, chain/belt, and we could mount batteries in the other hub, or have two wheel drive. | ||

Neat logo. All those Fs for Harley and Hero? In Indianapolis there are a boatload of rental E-Scooters downtown. How about your city? I had contemplated getting a job rounding them up at night to charge them and redistribute them before dawn. | ||
| Airbozo |
Looking forward to seeing one in person. Even hope tor ride it. Scooters: I would prefer to pile them in the street and light them on fire... with most of the riders onboard... SO got hit and shoulder checked the guy into a parked car. | ||

Seat shape looks familiar. | ||

Build something that can pick a fight with a ls-218 and it will be in my garage tomorrow | ||
| Airbozo |
Picking a fight and being able to win it are 2 different things. But then again these are bikes for 2 different purposes. One pure adrenaline power and the other a commute option. | ||
| Hughlysses |
So it looks like these are the same guys that were to run “Vanguard Spark” that was announced last year. I wonder if this is just a name change, or a new company? | ||

The 3 main dudes are on the webpage - Erik, FX Terny, and Fred Vasseur. This...looks cool. 125 mile range, ~30 min recharge time...not quite 3 minutes at the petrol pump, but definitely approaching "reasonable". Hopefully household 110v chargers, not goofy high-power stuff...can't wait for more specs and info. Surprised to see a hub-mounted front brake though. Perhaps Erik has taken a step towards mainstream/away from design eccentricity? | ||
| Jaimec |
You'll never get a half-hour recharge time on household current for anything I'd feel safe taking on to a public road. It takes a LOT of electricity to push a motorcycle and rider up and down hills. It's possible with one of those electrically-assisted bicycles perhaps, but not a full-blown motorcycle. | ||
| Froggy |
I assume the front wheel/brake is all off the shelf parts to keep costs down. ZTL is great, but likely to expensive to implement. | ||
| Airbozo |
I swear I've met FX Terny. Just can't remember where. Some C level conference or something like that. Agree with the charging. 110v is not going to get you a 30 minute charge. | ||
| Ratbuell |
I have my doubts about that hub-mounted motor... it seems to be the anti-thesis to Erik's "Trilogy of Tech" but we'll see what happens... But in this application, it is likely to help extend range. Think "heavy flywheel" in a normal engine - keeps the revs up, helps with freewheeling/coasting, puts inertia to work for you. Having that inertia as part of the road wheel can very much add to usable range, and I'm willing to bet those benefits outweigh (no pun) the downside of more unsprung weight... | ||
| Hughlysses |
One of the articles pointed out that the hub-mounted motor is a significant advantage as it allows the entire space within the frame to house batteries. | ||
| Tootal |
It's not like it's not been done before:   | ||
| Jaimec |
True, and this thing is NOT designed to be a performance bike, but an urban commuter so the additional unsprung weight shouldn't be too much of an issue. | ||

I can't wait for the Fuell Fightling and Psyclone . . . | ||

>>>>I can't wait for the Fuell Fightling and Psyclone . . . Love it . . . . There were actually, at about the time the Harley-Davidson deal was made around February 1993, a couple lingering bicycle designs that had been sitting in the can to follow the SASS. I'm already noodling to get my hands on one of the Fluids to hang here next to the first Buell bicycle . . . I'd guess . . . and no one is better able to address this than Stevea . . . that the focus on minimizing unsprung weight is less critical in a bicycle type commuting vehicle than it would be in a performance machine. This is really exciting . . . | ||

The turn signals on the grip ends are pretty cool! | ||

The questions with hub motors come down to what your performance goals are, and how low you can get the entire wheel unsprung weight? For an urban commuter, you can certainly tolerate a lot more unsprung weight than, say, on a open-class Superbike. There are literally millions of examples running around that confirfm this: every Vespa-style scooter has its entire engine and transmission unsprung, though much of the mass is fairly close to the pivot. The EBR-designed Hero LEAP electric scooter didn't do that and had very low unsprung weight, and it meant we had to use entirely different shock damping than typical for most scooters. As for the second part, you can do very light hub motor if you use advanced technology, and you gain more weight you can use for the motor if it replaces the rear brake. (If the bike is powerful enough to accelerate hard with a rear hub motor, the motor is powerful enough to lock the rear wheel under braking.) I'm sure a hub motor will work well in this application. | ||

The answer to the battery charge time issue is the flow battery. A fluid change as fast as a fill up. Ive been watching its development for years. Once it hits the market gas is dead. | ||
| Jaimec |
I remember reading about that and I have questions. For one thing, the fluid is just the medium that transfers the electrons between the cathode and the anode. Charging a battery moves the electrons from the anode back to the cathode. I don't see how changing the electrolyte would have any affect on that... Can someone 'splain, please? | ||
| Dstro |
The electrons/holes (positive charges caused by an absence of an electron)are carried from one electrode to the other by hopping from one molecule/ion to another; they don't just "appear" at the anode/cathode, they have to be transported there by a medium (the electrolyte matrix, that fluid you mention). This action of passing charge from one species to another (charge mobility) is easier with some electrolytes than others - they are not all created equally. Better charge transport leads to faster battery charging. Hope this makes sense. | ||
| Jaimec |
It does, but I fail to see how flushing the fluid and replacing it would "recharge" the battery since the fluid is just the transport medium. You basically just repeated what I was trying to say in different terms. Essentially, it would be like taking an ICE vehicle into a station to replace the fuel lines, then go right back out on to the road again. | ||
| Phwx2 |
You would have a tank with 3 compartmented bladder. As the 2 mix the go into the 3rd. When you recharge at hone on your solar array they re-seperate from the 3rd to the other 2. If your on the road about to run out, they drain the 3rd at the same time they fill the 1st and 2nd.you drive away with your slushy while you yell at the brats not to spill any. Oops this is a bike forum, you wheelie out of the station singing god bless america. |
