I have just had one of these, first one ever :o The thing is there is no such user name and when I try to send a pm it says not allowed ? Regards Jerry

Well its finally done. For details of this new lightweight motor (1.4kg, 100mm diameter) made by Tongxin and known as a Goldant motor, see this thread. Brompton unfolded Brompton parked Quick reminder of how the two Tongxin motors the current Nano (2.1kg) and new Goldant motor compare...

Ok being a throttle jockey for the last two plus years my latest project is pedelec only and I am pretty sure the controller is specific to the motor plus does not support throttle. Here is how I understand the pedelec function. 1. The circular rotating disk with magnets in it a) A...

Seems like a good place to post this link. BBC iPlayer - One to One: Lucy Kellaway with Anon I came across this link in the Brompton forum. You will see why it was posted there when you listen to it. More of interest is the general discussion. Parts are a little aloof but on the whole I found...

Probably a silly/anal question, but is there a standard torque setting for tightening the motor shaft nuts in the dropouts ? I tend to do mine by feel.... That all sounded so wrong :o Regards Jerry

These units facinate me :eek: My dad tells me about them every time he sees my bikes and how he rode his for hundreds of miles. If I had the time I would seriously consider getting it. Ebay link here I think this is a picture of the same one fitted. I am sure flecc will chip in. A couple...

I was going to fit a thumb throttle with the big red on/off switch but it is big has battery LEDs and looks ugly on my Moulton with just a plain thumb throttle. I need a kill switch as there is no cutout brake. I have now fitted a smaller throttle only controller like on my Brompton. So...

Been meaning to post some pictures of my re-working of my EMoulton TSR2 What you are looking at above is the completed bike ready to go with battery. Weight 14.5kgs. It uses the latest small controller I got recently with my Tongxins and my new £20 battery all in the bag. The battery 36v...

Re the picture on my Tongxin supply post showing a new kit I emailed them and they sent me a PDF brochure covering the kit and all the various motor and battery options. The motor comes in various sizes as does the bottle battery. The kit includes an interesting variable power assist unit. I...

As per my other post I have just received a shipment of Tongxin motors, controllers etc and they come will a new controller that is much smaller more like the original ones they shipped with them a few years ago, though the early one did have problems. Shown here about 1/2 the size of my...

For those still trying to source Tongxin motors I have recently contacted Outrider Technology Co.,Ltd and ordered a couple of motors, controllers, throttles and cut out brakes. Ebike Kit Supplier - Hangzhou Outrider Technology Co.,Ltd. They seem to have become more responsive if contacting...

How is it done ? This is my controller Its a cheap generic low powered one I think. I got it with my Tongxins when I purchased them directy from China. It says 31.5v which is too low as my cells would all have to be at 2.6v for that! I want to raise it so they cut out at around 3.0v ish...

I know I am a big fan of building A123 DIY packs but surfing over at Endless-sphere I came across these which some there have been using and building huge packs out of for a while. So the other good thing is they seem well tried and tested! Makita 18v, 3.0Ah power pack. The cell inside a...
