Hubmonster 94% efficient 7kw NO LONGER FOR SALE

[grindz145]

"Calm down" . Hey clueless, simply stop posting in any of my threads, because what rattles around inside your head and the real world are too commonly unrelated, and the connection to your keyboard is too direct. You've questioned my integrity on more that one occasion by insinuating that my results were fabrications. You post 2 year old videos of gasser mopeds to my Hubmonster video thread. You send me a flood of PM's forcing me to waste my valuable time with responses that you ignore anyway. You commonly post content to for sale threads that doesn't belong there. Now in my for sale thread you say that it would be "oouuuuu" so good to have something "called a "warranty"", which insinuates:
1. That you don't have one, which is wrong, expressly stated or not.
2. That you've had a problem that having a warranty would have helped, since without a problem a warranty is irrelevant.

This isn't the first time for this conversation, so no I'm not going to "calm down". Don't bother with another brown nosing note either, because the last one made me want to puke. Words have consequences, so be a man and accept the consequences of yours.

John

John,

Get real man. You're over-reacting to someone who has built some cool shit with your stuff, and is a fan. Don't attack your friends man, wtf.

His point is that buying a Zero means allowing someone else to build the first 10 iterations for you, and you can ride the shit out of it without worrying. It is the complete opposite of the hacker mentality but for all of us that live it (and all of us in this conversation do), and have to frocking break out the multitool on the way to work everyday, you can understand the value of having something with a warranty, that you don't have to fix when it breaks. It's not even fathomable for most of us, but it's nice not to have to worry about the technical details sometime, and that's what hes talking about.

Not sure what your complex is, but in no way were you being attacked, all of us here are the warranty voiding mentality, and that's the point.

Grindz145,

Don't fall for the ploy that HOV is just an innocent victim and John's just mean and hateful. That wackjob stepped way way across the line a couple of months ago. I'm not going to get into the details, but until recently he was okay with the "just stay the frock away from me" way it was left. Friend...LOL! Thank goodness I don't have any friends like that.

 

[grindz145]

Fair enough. None of my business. You two teenage girls can work it out among yourself :wink:

 

[Toby82]

Love the Motobecane. This was high on my list when I looked for a conversion bike but they are a little rare here is Aus.

The mighty Honda CT110 "postie" is what I'll be fitting my Hubmonster to.

I finally got the motor fitted into a 16" rim for those interested. see attachments. The rim is a 83 or 84 model VF750 front rim. 2.5" wide. I designed custom plates to fit between the motor and rim attachment points.

Now to start on the custom swing arm.

 

[jansevr]

toby - that looks awesome! good luck on the swingarm...also what frame are you using?

 

[grindz145]

Gorgeous wheel!

 

[John in CR]

That worked out nicely Toby. How thick are your the AL plates? Now the challenge is doing as good a job trimming weight off of your postie, so you can run it a fun performance levels. That's assuming you're keeping it sealed. The way I look at it is the 175kg I pushed with mine sealed at 20s was dancing with the limits of no heat worries. That was with a 19.2" OD wheel, and about the smallest you'll be able to get on that rim is 22" OD. That's a 15% increase in load, plus running at generally lower percentages of no-load also increases heat, as I've found out running 30s vented. If at all possible, I'd shoot for a max total load of 150kg with a 16".

Now that I have my own 16" rim, I'll know more as soon as I get another bike built. Then I can run it with the larger wheel with a sealed motor and with a vented one. I'm attacking the load issue from both ends, with the bike and with myself. Since no normal weight people seem intent on running HubMonster on a 50-60kg ebike, then I'm going to shed my dead weight and find out what it's like first hand. Increasing the power-to-weight ratio by reducing the total load by at least 20% by Christmas is my goal, and that includes overcoming the added weight of moto brakes and moto front wheel. Chromoly, carbon fiber, and a mountain of veggies fruits are calling my name.

[Toby82]

Thanks guys. Yeah the rim turned out looking better than expected.

Jansevr the bike is a Honda Ct 110 otherwise known as a Postie here in Australia.

The plates are 6.5mm thick 6061 T6. I think they are a little of an overkill but the added weight was slight for peace of mind.

I'm yet to weigh my Postie in its current form but I know I have removed a little over 10kg of weight so far from the stock 95kg. I'm hoping I can drop a fair chunk of weight using alloy rims and 16" performance tyres. The stock tyres are chinese and look quite heavy. I managed to pick up another postie frame last week so I will now be able to weigh it and get a better idea of exactly how much weight I can save running alloy components etc.

I will be running a 90/80-16 tyre which will be 21.7" OD.

Yeah getting a bike weight down to 50-60kg and still be able to register would be great. I think for the Postie if I can get it under 80kg converted I will be a happy camper. Will have to wait and see.

Cheers,
Toby

 

[Tinto]

Very keen to see how the postie turns out!

 

[John in CR]

I couldn't find a 90/80, so I ended up with a 90/90. 50-60kg that can be registered is a tall order. I don't want to register anyway, so mine may be too much like a bicycle to pass. I just want to get some stronger components, especially brakes, without adding net weight. With the 30s pack and dual Zombiess high voltage 24s, my SuperV is scary fast and quick. The regen braking is mellow, so an emergency braking situation would be relying on primarily the bicycle disc brake in front. Add in my big load and scary fast and quick becomes terrifyingly fast and quick.

The Zombiess Throttle Tamer give me such nice and smooth response that it's very deceptive, so I commonly end up at speeds far higher than I intend. The other day on my 2.5km run to the grocery I got on the throttle good only once for maybe 200 hundred meters coming out of a turn. When I checked the CA like I typically do when I stopped my MaxSpeed for the trip was 111kph, and I didn't even mean it. Yeah, I need better brakes. The lacking brakes does make me ride more conservatively and really focus on what's ahead, so it's not all bad.

Wheel looks great, will be nice to see another hub monster alive in Australia. Mines working great even after i managed to kill a hall sensor hitting it with main pack voltage by accedent. The 2 controllers from john are running it perfect of the CA V3 running both just by connecting both controller throttles to the CA output. Zombies throttle tamer is great but i still think for these motorbikes a mangura throttle and a few small resisters = killer control

Been great dealing with John while building bikes with both the mini-monster and the hubmonster. Tho i really think were are only seeing a fractions of the motors potential putting it in wheels and at such low voltage RPM. Really need to get a hub monster or mid monster into the middle of the bike under 150V to really make it sing Next bike will be a mid mount for me for sure now that i realized a hub mount on a motorbike is pretty much the same amount of work and cost as a mid mount.

I realized i wanted to push the same weight as John normaly runs but at ~30kw rather then 20, so about the same as Hillzofhelp is running so i finaly got around and vented the motor slightly, dont want it falling apart, did not really think the thin cuts would work well so i removed some larger area with 10mm angled cuts Already installed 4 blades atm i am trialing some thin polycarbonate sheet may change to alloy later.

 

[John in CR]

Nice work Bluefang. I'd love to see how you did your blades. You're right that the thin slots don't flow a lot of air by themselves. I had hoped that having so many with each acting as small blades would work well, as well as keeping the motor impervious to rocks and debris. While it does flow air better than the bladeless approaches we both tried, it's not a big enough air flow to really be able to unleash the motor. Adding six 1"x1" blades at the perimeter changed the ball game with tremendous flow, so even at the 30s 250A I'm running now for over 25kw peak input, I don't have any hot motor concerns, and I know I could go higher. My next version will be a more simple approach with just 6 slots like yours, but shorter so they're only at the perimeter. Then a thin slot for a slightly angled large blade mounted from the outside in front of each exhaust vent.

I can't wait to see the finished work of you and other artisans who are working with HubMonster. I'm just a hacker with a ridiculously fast ebike.

[jansevr]

looking good bluefang - now its time for some more videos of this 20-30kw that you guys keep talking about

 

[cwah]

John, are you able to sell Hubmonster or cheaper mini-monster for 135-140mm dropout bikes?
I have this to electrify:

Would that work?

Sure, almost any bike can be made to work, but we don't sell any motors to fit in place of a regular bicycle wheel. It's simply not appropriate, just like you would never find a large block V8 gasoline engine that is a bolt in replacement for a Smart Car. In time for Christmas we will have frames made specifically to fit our motors, both in-wheel and mid-drive. Until then customers need the tools and skills to modify their bikes to fit one of our Monster motors.

Yes of course, though I don't have any more that got a nearly free boat ride.

No joy yet. First prototype of each type was unacceptable. I left the guy with the bicycle fabrication shop too much to his own devices and the result was something I wouldn't ride, much less sell to others to ride with big power. On top of that it was ugly. Now that the weather is finally drying up a friend can also help for a more hands on build and leave the guy with the shop working on only the cargo model, which I believe will have more local appeal as a family ebike as transportation with a wife and kid or two aboard. Once I have something reasonably presentable I'll show it and solicit input from you guys. At that stage builds can happen quickly and in volume.

Under the tree for Christmas isn't possible, but something ready enough for lots of pics to take deposits with a 30-45 day shipping commitment is still within reach.

John

 

[cwah]

John, are you able to provide approximative cost including shipping?

My ideal bike would be:
- bike able to reach 50mph
- amazing torque
- can be a stair climber
- able to carry a passenger
- and if possible not too big as I travel a lot, if I can bring it with me in luggage bag inside train/bus that would be perfect.

Just raising you what I'd ideally want, even though I know you'd make an unique design for all :lol:

 

[John in CR]

cwah,

An everything to everyone bike isn't possible. Some of your list of wants seems in conflict to me. eg High speed with great torque and foldable to baggage size isn't reasonable even after a 4X improvement in batteries and speed requires more wheelbase. Passenger capable requires wheelbase too, and I think that's in conflict with a stair capable city bike. You need 2 or 3 ebikes.

Price is unknown, but base units will be as low cost as possible, and low labor costs here gives us a competitive advantage over developed world shops. Of course variations with costly exotic materials and/or custom dimensions would be higher priced, but I have too much of a conscience to ever come close to what I consider to be the larcenous prices so common with bicycles. High volume is our goal. Regarding shipping we will work toward cheap shipping at least to N America, but bulk shipments to Europe isn't in the cards at this point. CR exports a lot of bananas and coffee, so if much of that goes straight to Europe, then I could be wrong and relatively small volume crates could be economical.

First are the bikes and getting past the vaporware stage as soon as possible.

 

[cwah]

understood.

Just waiting for you to come with some concept... or some prototype then

I'm eager to see pictures
