"stokemonkey" my Tongxin?

[kitchenman]

When I say ferrule I mean olive! ... and it seems it may not need crimping! ... There is a small thread at the cable end that may screw into the brake lever ..
umm or maybe not! ...
No. Thats rubbish. I remember when I took the old cable off. There was no unscrewing. Therefore the ferrule or olive needs to be crimped! ...

I think if it is an olive it will crimp itself when you tighten the pipe fitting. That is was usually happens with pipe olives in my experience but I haven't worked on maguras before

Ah! Interesting. A self crimping olive. Excellent. Would definitely not thought of that!
Thanks oigoi.

 

[kitchenman]

Ok.. Sorted! .. Not sure why I was so apprehensive. Its definitely easy with 2 people. Thanks to Richard at work for helping me. No thrills. So spills. I now have full braking power again! ...
Only bad news was another chainwheel failure which must have happend this morning and at £10 a pop I really need to sort it.

Done 700 miles now. Tongxin looked in need of a clean. After the clean:


And this is how I did it:

Keep persevering with it, I have put a lot of miles on mine with no issues since the first ride, had to tighten chain a bit more.
I did nothing fancy and there were a lot of people who said the pedal would come loose constantly due to the reversed thread but I have never had to tighten it since install.

Nice one Geebee. Bike looks great. I had a couple of pedal problems but that was simply because I didn't tighten it up enough. My main issue is due to having to route my chain over my front wheel forks using chainwheels. I've snapped a couple! Made a change after the last one broke and so far so good ..

A few questions about your rather excellent bike:
Is that a front Tongxin motor?
Have you got a free-wheel between the motor and the crank@ If so, where?
Do you ever get problems with the chain jumping under load@

 

[Geebee]

Yes it is a rear Tongxin, it has a free-wheel screwed on the "wrong side", the chain has never jumped or come off since adjusting on the first ride including riding 20% grades regularly.
There is no free-wheel in the crank, it is geared to be at 70 rpm at the crank at rated motor rpm and by 77~80 rpm there is no assistance, which means it gives a good boost as needed but at my cruise rpm is not using any power.
The black box has been removed for the last year or so, it was for the speedo and wattt meter.

Hello kitchenman, I have been reading all the post great job!

First which tongxing rpm have you got ?, i supposed the 190RPM which will be better to get the reduction to 70 rpm.

I have some doubts: You attached that aluminium piece to the hole of the spokes and then the sprocket to this aluminum pieces because your hub hasn't got disc mounts isnt it?

If you mount a fixed sprocket in the disc mount of the hub, would this works for freewheeling ( i mean pedal with no motor drag when motor swich off?)
when you dont want electric assistance and the motor is switch off, when you pedal the motor hub is spinning but thanks to the inside freewheel of tongxin motor there is no drag coming form the motor, isn`t it?
In case the motor was direct drive, you couldn`t have this configuration, cos you will have the motor drag isn`t it?
I.e. the stoke monkey seem to be a direct drive motor and they have mountend a freewheel sprocket to have freewheel between motor and chain when motor not working and you are pedaling. Then 0 drag from motor when switch off , Am I right??

Thanks steele. Mine is the 175 rpm. I would like to try the 190 rpm version in future. Mine isn't the disc version. I am only using the freewheel in the motor. If I add a freewheel then it would be in the front chain ring. I dont have any noticable drag problems. Not sure what difference a direct drive motor would make... but I think you are right.

 

[steele]

I didn't know there is a 175 rpm version , I only know the 190 rpm ( supposed to suit 26" in) and the 260 rpm to suit 20''. I supposed yours is suit for 28" wheels...
What sprocket / chainring combination are you running?

Are you running their controller ? I want to order a hub motor from them but not sure about what accesories to get:
hub 36V /190 rpm with disk brake + controller + Thumb Throttle
Does the pedelec sensor makes sense in this configuration?


pd. I have also got a streemachine ( just get it yesterday)

 

[kitchenman]

Yes. My hub came off my 700c wheeled Cannondale. My sprocket has 16 teeth and the chainring has 32 teeth. The controller came off the Cannondale and I think the supplier (Cytronex) may have made some modifications.
You've got a Street Machine! ... Cool .. Nice one ... Are you going to Stoke Monkey it?

I doubt Cytronex will sell you parts. They are supposed to be bringing out a kit but to date its been vapourware. The alternative (if you specifically want a Tongxin) is to order from here.

I have just placed and order as per that post.

I would say that the pedelec sensor is mandatory in this configuration. I dont have a throttle and don't miss it. I'm not sure how you would configure a throttle with a Tongxin ...

 

[jerrysimon]

I use throttle only on my Tongxin. Connections are available on their standard supplied controller.

Of course I never engage the throttle until "after" I have started the bike moving first. These motors are light, small and quiet but need to be treated with care to make them last.

This is probably the motor you are looking for

Thanks Jerry. Don't think a throttle is relevant in my (or any) "stoke monkey" situation. If the motor turns then the pedals turn! ....

Yes this is what i am thinking and in this shop, i have contact them before.

They also have the controller and diferent options: throtle, throtle+pedelec. Etc. They told me you can have pedelec and throtle both together. So it only works when you are pedaling and you can set the rate of power with the throtle.
I am not sure what to get. I want to be able to use it with motor off. And with motor on, i will prefer the motor run "automatically" without much "human" iteration.
I supposed in any case I also have to bought a brake-sensor so inmetiatelly stop when you brake.

Yes I have a stree machine gt ( steel) bought it two days ago. My plans are to stoke monkey. I want to get used to it first, it is my first bent and I am impress how confortable and easy to ride is!!
