Yes that is what I use though I only used it initially when I first set up the system. I also have a 15amp fuse in the circuit. Even with my existing Tongxins I can get 17amp spikes but they are probably for ms only. Regards Jerry

Dave happens on both motors so I doubt its a wiring fault. Looking at the speedict it seems you have to buy different options including wiring to interrupt the throttle signal if you want to control it. NRG and Amigafan I have emailed both lyen and ecrazyman with details of my motor and...

Ok I have tried three different Tongxin controllers with the Goldant motor and they vary from barley working with throttle only, to working but very rough/stuttering/clacking and not going to full speed. I am uncertain how to proceed. The choice I see here is a Lyen, Ecrazyman and/or speedict...

:rolleyes: I had a Dahon JetStream P8 briefly which I wanted to put a narrow motor in the front forks. However the profile of the forks meant I could not even fit a narrow 80mm into the forks. This means you have to fit a rear motor. I picked mine up as new/unused on ebay for £450 Here is the...

Thanks Dave I do now remember that little device but had long since forgotten it. I will initally try my other controllers and then take it from there. PS the Lyen controllers do seem to offer a lot of congifuration in terms of adding cruise control, three power step etc. Regards Jerry

Thanks for the replies very helpful. I don't really need a programmable controller as long as its 36v and 12amp max. The real issue here is that on my small Tongxin controllers the throttle function is a little rough with the Goldant motors. I do have a couple of the older larger Tongxin...

Thanks amigafan2003. Did you/can you adjust the throttle setting with the controller as I have tried it with a Tongxin controller as I said and the throttle is quite rough and not very linear ? I have emailed the guy you gave me in the link. Regards Jerry

Interesting thanks. Is the throttle smooth through the control range ? I did try a Tongxin Nano controller and the throttle control seemed rough and the motor juddered and was noisy. Maybe I need to take a look at the Lyen controller. I would need it to be set to 36v and 11amps as I have no...

This has just been posted on another site. You need to watch it right to the end. http://vimeo.com/43038579 I am not sure if I am convinced but its certainly different! Regards Jerry

Thanks for the comprehensive write up and good to see another one of these up and running. An on off switch can easily be added by putting it into the brake cutout circuit. But is that even needed ? Doesn't adjusting the slider "power level assistance" on your system not turn power off ? I...

Sorry Dave meant to get back to you about this. I am pretty certain the front ones ARE Tongxin Nano like in terms of having roller bearing drives. The discussion on esphere I think was related to rear motors which were supplied. If I get chance I will open up my spare 36h Goldant one and...

I cannibalised existing ebrakes (they are readily available and quite cheap) which I then took the switch out of and modified the stock brompton brakes. I actually only did one brake. Some even say they are not really needed but I like to be able to cut power. Only works with the latest...

The bike is not mine its slippa's :p Slippa you could try on some of the other small wheeled forums to see if anyone recognises it on there. Certainly very interesting. Maybe try the folding forum first. Regards Jerry

Are they smaller 16/20" wheels ? An interesting find :) Jerry

So what kind of 20" wheeled bike are you looking at :p I have now built over a dozen small (16" and 20") wheels some with motors in them. Would not say it is hard, just takes application and patience to do some on line learning before you can build a nice solid round and true wheel. For...

For me I do not find that the case. We are what we are and for me that journey and acceptance has been a long and tortuous one. I am no longer a religious hence I dislike the idea of people being told they are flawed or sinful (I know you probably did not mean that). Although as I said I am no...

I voted No. I could choose not to ride a bicycle and therefore be certain I would never be knocked off one. The helmet debate will go round and round. Why don't we just have it as a sticky ? Regards Jerry

By their very nature (in these days of hype and spin) any prime minister will not serve the best interest of the majority of people. They will only have got to that position through devious means and self promotion. To a large extent Governments are bought and paid for, or as they say "the...

Slaw, Outrider do sell them I think but the better contact for the Goldant motor is Sky at Keyde. Note this kit is really only pedelec only and although you can use a throttle the pedelec will always be needed and over ride the throttle. It may be better for you to think about the Tongxin...

The only way you are going to stop the scooter in that setup is by either connecting up the cutout to an ebrake/and or have a switch to turn it on/off. Ideally for a scooter I think a throttle only setup would be required. PS thinking about it the switch would need to fail closed to turn the...
