Motorcycle class Hub Motor

[toyguru]

Christini AWD bikes (www.chrisitni.com) has a great solution for that, a mechanical drive up to the front fork, through 2 counter-rotating shafts down the fork legs to hypoid gears on the front hub.
I have one of their mountain bikes, and it works great, and very light and efficient.
Anyway, I know that's off topic. Mark, great job, I can't wait until you're starting to sell these to drooling masses. As Gary asked earlier, do you have a ballpark figure for sale price yet? Are you selling them laced to a wheel?
We're all very anxious to see the performance numbers and a video.
Keep up the great work!

I gotta admit, that's a pretty slick setup......

Oops, threw an extra 'i' in there, thanks for the correction.
I haven't tried their motorcycle kits, but I can tell you the MTB version is awesome!

The work continues and so does the testing though still no hard numbers as I have been tweaking the Kelly controller. Once I feel I have it right I'll start logging data.

As you can see from the pictures the "what was the gas tank" is on

Mark.
Looks great. I want one of those motors, how much are they? Sorry haven't read the whole thread yet, you may have already said. How can I get one, I have a motorcycle to convert, orinally a 500cc, so should be strong enough for battery weight....Hook me up!

That's OK I haven't quoted a price yet but will soon. The results of my testing is going to result in a better product, I promise and it will be worth the wait. MY goal is not just to sell a motor but to sell a motor most everyone will be happy with and can compete in every way ( may even be better) with the chain drives motors currently available.

So weird to see a motorcycle with a hub motor. I wonder how the high wheel weight affects suspension and cornering? Have you tried it? Please post impressions once everything is working fully.

Video time
Took the bike out today for the first time to run errands and just ride. First time I ventured far from base so to speak. The build turned out well, very little shake out, outside of getting the Kelly right I haven't done any rework, guess I'm finally getting good at this build thing. She is fun to ride.

I know the question when can I buy the wheel believe me when I say this something very positive is going on between Crystalyte motor and EnerTrac Corp. (Kenny and Myself) that will result in a greatly improved design over this current motor I'm testing (even though this is a good motor). We agreed to introduce a motor that can stand up and potentially be better than most current motors being used today for motorcycle conversions. So hold tight and get your rolling chassis ready, choose your batteries and get prepared because the Motorcycle hub motor is coming.
Edit: It will happen cause I'm working my butt off to make it happen 8)

By better do you mean more power?

Looks like a pretty straight forward and cheap conversion on a bike like the lifan.

I mean lots more power

That's the point to the hub motor a easy straight forward conversion, as far as cheap - it's all about the batteries, over one third of the cost is batteries

You skipped this question "I wonder how the high wheel weight affects suspension and cornering? "

Can ONLY affect it in one way...badly. Unsprung weight off a swing arm will do nothing but bad for the
suspension. Casual commuting would be fine but hard sports riding would produce some shocking handling.

Come to think of it 'sports riding' won't be possible if the speed of the bike in the vid clip
is the limit of hub motors? ... Best of luck with getting them manufactured anywayz, im sure
they will make it alot easier for some to convert motorciiicles, have you any guesstimates on pricing?
will they at least be cheaper than the Agni or Eteks?

That sort of depends on how much heavier it really is than the stock wheel.

Yes it does, and it will be heap heavier than a light weight motorcycle hub with only a sprocket
it on it dont you think? Just look at the weight these fellas throw on the back of their pushbikes
ie. X5's for example, then throw 100 plus volts at them to get them to do 45mph when 48 volts
on a 750 watt non hub running gears will get there quicker and go faster without destroying the bikes handling...
OH thats right hahah they 're "noisy" haha dear me...
no brainer which way to go if your looking for performance IMO...the hub has its place for sure,
makes installation simple and quick for the less technical/equipped no doubt but at the cost of
heavy rear wheel and looking at the lacing a substantially weaker one too, i wouldn't use one if you paid me, experienced first hand a wheel collapsing not a pretty thing. Unless a cross 2-3 pattern is achievable
which i doubt it is seeing the diameter of the hub in relation to the wheel your stuck with a weak
yet heavy setup IMO, not something i would risk using with the weight of a motorcycle and
the speed involved, get away with it on a pushie as there is less weight and speed involved.

Correct, not for hard sports riding is that the answer you wanted, wouldn't want to avoid your question now. Yet for me on the roads I ride and for the way I ride its fine. How do you answer such a question except say come and ride my 2 bikes both with the hub motor and evaluate it for yourself. That's why I build the Lifan into an electric bike so before someone makes an investment of several thousand dollars in a bike, batteries, and motor they come and ride the bike. I'm not introducing a hep of claims, I'm saying, its a hub motor and it comes with all the pluses and minuses that go along with it being a hub motor. If you live in the USA a plane ticket to New York for a weekend is a small investment as compared to the cost of a build with LIFEP04 cells.

I say one thing you can't beat the quite of a hub motor

By the way I'll bet some cast aluminum road wheels on some of those cruiser bikes I see like a Vulcan 1200 with a cast wheel with a drum brake weigh as must as the hub motor I going to sell with a aluminum rim and cross 2 spoke pattern. This has been discussed with Xlyte and worked out, all components will be DOT approved and NHTSA resistered.

This is not a sell thread so I won't discuss price. This is a design, build and evaluate thread and up until now have gotten good constructive help at making it the best product it can be- a powerful hub motor.

[AussieJester]

Only plus i see is the ease of installation, if you can make the price competitive there will be another...the noise is a mute point IMO, others will disagree i guess...Wouldnt ride the bike even if i could though thanks for the offer, if it aint a ICE motorcycle im less than not interested. I do wish you all the best though with getting them manufactured and sold at a competitive price, they will surely be very helpful to those with less skill, tools and time etc to fit up the non hub type conversions which lets face it, is a bit of an undertaking, ALOT of custom fabrication required, your alternative is definitely ALOT easier way to go for sure

Kim why be negative I'm not pulling a rug over anyones eyes yes it going to be heivier that a good sports bike wheel and sprocket. Yes if you ride a R1 sports bike and you want that kind of performace from an electric motorcycle the hub motor is not for you. If you want an excellent commuter bike that gets you where you need to go and because its a Hub Motor, it frees up the engine bay for an amount of batteries that can go a reasonable distance. The hub motor can make a lot of sense. For a bike you can build without any welding that opens the bike up to hold a practical amount of batteries, yes it's a compromise but one that works for me. Please come ride the bike and see if it will suite your needs that's all i'm saying

Ease up a bit bro, he is selling something for making a comuter bike, like a scooter, except with the stability of a motorcycle.

Personally, while I'm the type that bought a nitrous kit to boost the performance of my 190bhp GSXR1000, I can still see where this has a nitch. It's not a racing part, but it does make a silent simple way to transport yourself around the city.

I was thinking the same thing.

 

[JRP3]

Another thing to consider is you also don't have the weight of a chain either, so that should be taken into account as well when considering wheel weight.

 

[lawsonuw]

I've been watching this thread for a while. The Li Fan conversion has a really clean look. I especially like the oversize axle with provision for a bolt on torque arm! I'm curious how well the motor climbs hills?

And as i have now said twice i wish him all the best and it will be a viable option for many, simply voicing my opinion as you do Luke, i make no apologies for that, it's simply my opinion

Once more all the best Mark

Another great advantage of a hub motor is that it frees up a bunch of space in the frame for batteries. I have a few dirtbikes that I would like to convert to some supermoto type bike, but the frame space is severly limited. Having a hub motor would make it a possible build. Also, the original top speed of those bikes isn't that great, so this would actually be an improvement in performance.
AJ, I think it was just a little because you kept saying it. That's cool that you have your opinions, and Mark is welcoming constructive criticism, but to just keep saying that you won't ride on one more then once just seemed a little disrespectful in his thread. You are a cool guy and I'm sure you didn't mean it maliciously, but just seemed a bit much.

 

[liveforphysics]

I also respect his project because he is making something. He is using his hands to build and create. That's always awesome in my book.

Just like your trike build, which uses a steep rake angle and springer fork, which are awful for both handling and suspension, along with SLA batteries with are awful for performance. However, it would seem pretty dick to take a dump in your thread by posting that in the middle of your project, even if it is just fact and my opinion.

Think of this hub like the front end on your trike. It's not the best for performance(though you did an outstanding job with the finish work), but it does offer what it offers, and it gets the job it was made to do done.

Different strokes.

Me to will find some hills on the North Shore of Long Island and let you know. I have a garmin Forerunner 305 I use for cycling and it lets you overlay your route onto google maps using Motionbased a free on line app. and you can veiw the course and the elevation at any point in the route, all part of the testing.

Well i appologise if it seemed maliciously it wasnt meant to, for the record i only declined his offer to ride on one
occasion.


Luke...if you can fill the chopper building fraternity in on how to build a chopper without rake
and still look like a chopper im sure they will be happy to here it buddy, the trike was built as a
chopper/cruiser would look pretty stupid setup like a 'standard' bicycle' don't you think? not too
mention WITHOUT the rake and appropriate trail that's built in it wouldn't handle at all as is evident
in the store bought delta trikes, springers were used wholey and soley for the looks...but i get where
your coming from and shall watch how i express my opinions in future...

Sorry Mark if i offended you it was never my intent.
