Adding pedelec control to Brompton Tongxin

[emtemt]

Hi

I have a Brompton with Tongxin hub/controller and throttle control. A family member has difficulty with the throttle due to hand tremor. I would like to change the electrics so that it is pure pedelec without the need for a throttle. Is there any way I can do this with the existing Tongxin controller? If not does any one know of a controller available that will accept a pedal sensor that is usable with the Tongxin sensorless hub motor?

Regards

Ian

Yep try one of these

You will need to either get them to progam it for max 12amps or do it yourself. I think they sell it with a pedelec disk and sensor if you ask, $3 extra. Also do not forget to mark in your payment to say you want it SENSORLESS as well, assuming your motor is sensorless which I suspect it is.

Alternatively if you can wait a bit till I finish painting this room lol then I will check my box of bits as I think I have a few original Tongxin controllers which have pedelec and I will send you one for the cost of postage and if I can find it a pedelec disk and sensor too

PS with pedelec control you will need a cutout brake to prevent overun as well. I may have a spare one of them too.

Many thanks Jerry

If you do have a controller with pedelec disk and sensor I would be interested. The Tongxin is sensorless. I already have cut outs on the brakes.

Ian,

I do have a Tongxin controller with both pedelec and throttle function which I will happily send you. I don't have a spare pedelec sensor and disk though

If you want it just PM me your address and I will pop it in the post next week
