Aikema make their motors for OEM, I suspect they make them for bmsbattery.com.

The one I like best is this one ($112):

I had their Q128H, with freewheel instead of cassette fitting. Lovely motor.

The Aikema 100SX I referred to in previous posts is equivalent to this one:

OK, now I understand!!!

 

As I say, try the bikes and you will see.

 

All the best, David

These Aikema motors, are they available to vitae a kit, if not ,writing about them is pointless,the OP was asking about kits ,further confusing him!

 

By the way OP ,do you need a folder to zip up and down your hill that you call a mountain,a full size bike will likely be lighter,plus you can fit a centre drive motor and he the gears,which provides better climbing

Yes they are. BMSBattery.com Q100, Q100H and Q100C. You can also get them under different designations from Greenbikekit.com and Elifebike.com.

When I spoke with Aikema in Shanghai. They said that the Q100H sold by BMSB was not one of theirs, so they must be clones. I've never had anything to complain about from the clone ones.

Hi Gerald the OP says "Still looking at secret, wisper, and others but would like bigger battery," in his opening post, hence my response. If he hadn't mentioned Wisper by name I probably would not have offered my advice.

My point is about increased inherent risks of two-stage reduction versus single stage. Overheating and shortened life expectancy of the ball bearings. It's the same situation with the Xiongda XD motor, two clutches against one. I had it but not rolled it out. You gain something but you always have to pay a price in return.

what do you see?

 

I understand where you are coming from Trex, nothing more than I would expect that from a Woosh salesman, I hope you understand where I am coming from too. I can assure you that we pay considerably more for our motors than you have indicated.

 

As to whether 8fun or AKM make better motors, the proof of the pudding, as always, in the eating. Having sold thousands of both and knowing the reliability of both I would not go back to Bafang unless they improved dramatically.

 

I really don't want to argue here so I rest my case. If you want to discuss further please PM me.

 

Kindest regards, David

for the record, it wasn't me who started the spat.

Benjahmin, thanks, so was the crossfire a standard bike initially? and did you fit conversion? What was total cost and how easy to fit?

Yes it was a standard Halfords Crossfire bought for £255. The Ezee kit was one from a previous bike. Front hub with 14Ah rack battery. Kit price was around £800. As I say, not the cheapest but robust.

You can see my thread on the conversion here:

http://www.pedelecs.co.uk/forum/threads/converting-a-carrera-crossfire3.21965/

And this is the kit I used:

http://cyclezee.com/ezee-conversion-kits.html.

Kit is still going well after some 3500 miles. Only problem I've had is a shot bearing which he helped me sort within 24hours.

 

All in all I feel that a conversion gives you a bike that you understand better and one that you'll be able to service/repair yourself, given a moderate practical skill level. AND there's loads of help to be had on the forum, commercial spats notwithstanding:rolleyes:

No really they're nice blokes and are very free with info. I blame the Mega Moon

That's nonsense. We have practical experience that they're reliable. Even Cwah couldn't break one, running it at 48v and 20 amps.

That's the thing. cwah did not get 5,000 or 10,000 miles out of his bikes, he killed them well before that.

If you take a bike like the Karoo or the Bermuda with Bafang motors, they'll go well over 5,000 miles. Woosh bought 10 clutch units for Bafang SWXes back in 2011. They still have a couple left. That goes to show how reliable Bafang motors are. I bet you can search the internet but won't find a user with a two-stage reduction gear that has done over 10,000 miles.

Don't put them in your Woosh bikes then. The rest of us will enjoy them for what they are.

I was about to, in February, when this video was posted on ES about the 100SX:

That got me start digging into the clutch.

I thought I posted something about a spring that came off the clutch last year.

wow guys, if you read above posts from an outsiders eyes you can see why I and maybe many others are in total confusion over my original posting.

I value your responses and views but this is where I go into another period of what the f..., I`m lost. someone is making a good profit [and why not if they can?] Someone isn't being given true figures/facts from manufacturer/supplier? BUT I am left as a novice still wondering which is best. I appreciate every decision is a personal one , but all I am asking is from you experienced guys and gals, which bike for the money is better value for my needs as stated? I could pay £1500 or £750.00 but will I regret if I buy wrong one?

I could advise which engine in a T4 camper, purely from experience, best mpg, best reliability, etc from years of trying them all.

I just need similar advice on a folding electric bike. Without spending 2k or so.

Thanks.

Pete.

Probably the 1.9td for easy maintenance or the 2.5tdi for performance?

A kit for your carrera bike,maybe the oxydrive cst kit,on offer at £600 at the moment,14ah battery and i believe the bafang cst motor is one of the best climbers.

Edited November 14, 20169 yr by fishingpaul

Oh and back onto the original subject, I fitted a kit that cost £400 and I'm happy with it.

The Q100, like the Xiongda is exceptionally free-running because the clutch is outside of the gears, so only the hub rotates. When a Bafang free-wheels, the gears go round because the clutch is between the gears and the motor.

 

That Video isn't at all representative. Firstly, you don't know if he installed it correctly. Secondly, you get tight seals with any new motor. Thirdly, the Q100 is very light, so it doesn't have as much momentum as a Bafang.

 

I hope your whole decision wasn't based on a third party video. There's nothing wrong with Q100s. They have a lot of advantages over a Bafang. If you tried one for any length of time instead of trying to theorise it, you'd soon realise those advantages.

Either of the Wispers would be good, the Torque version would give you huge climbing power. Both offer disc brakes for safe stopping down those steep hills!

 

All the best, David

I would swap my Birdy for one of those.

...

no, it's not entirely based on that video.

I have been looking for ways of increasing torque without having to carry the weight of the BPM. The Xiongda XD was promising but Xiongda could only make it work with the flimsy KT controller then. I gave up on the XD after a few months and looked into the 100SX. The latter weighs haIf the BPM and costs a third less. I was tempted. I got samples to test.

My bigger worry was the screw lid with the worm screw on the side of the 100SX. The woosh Sirocco in 2011 had that lid. You can ask Andy how much he hated it. After abandoning the 100SX, I tested the bigger Q128H which doesn't have that lid but requires 48V to get the Watts out. I pushed the Q128H until it started to whine and squeal. So I gave up on the Q128H. The Panasonic hub motor has two-stage reduction too but nobody bothers about it any more.

Nothing wrong with KT controllers. I have them on all my bikes and wouldn't use anything else. Why do you say flimsy?

oh they work, I have them as well on prototypes, but not on production runs because they are not as well built as Lishui controllers. Lishui controllers are housed in larger casings, the crimp connectors, bolts, nuts and rubber gasket are also of better quality. KT pack a lot of features into their controllers but exposing the internal registers to users to tweak is asking for trouble.

 

6-FET controllers:

 

Lishui casing: 96mm×66mm×33mm

Small KT casing: 78.5mm x 48.5mm x 26mm

Larger KT casing: 87.5mm x 52mm x 31mm

 

Lishui charge about $7-$10 premium for their controllers. Lishui are the largest manufacturer of e-bike controllers.

I wish I could buy one...

 

After the announcement of the BlueTooth controller months and months ago has anybody ever seen one in the flesh?

 

Tonight I will be opening my first Bafang to see why it is making lots of noise on a friends bike. I wish I could open my Mxus to grease a little but the screw on side plate is stuck and even d8veh's method didn't work to get it unstuck including using a heat gun... Next time I buy a hub motor easy servicing will be high on the list of required qualities.

I am still waiting for mine.
