You have to start by deciding on the performance requirements that you need:
How fast?
How far?
Budget?
Your weight?
What type of hills you have to climb?
Any other special requirements?
Which bike do you want to convert?

What replacement parts do you need? If you already have a kit, there's loads you can do to improve it without spending that much.

What else do you need other than a charger and a controller please ?

I have pointed out where you can get both for less than 60quid delivered on your other thread ? Ie BMS battery, eBay, me or a combination of the above

BMS also do throttles for a couple of quid if that's also an issue

my understanding is your battery and motor are fine. Is that right ?

If you need both a controller and a charger, you can get them from BMSBattery. You can upgrade to a controller with LCD, like the S06P, or you can get the KU65 that comes with the control panel with three levels of PAS. There's also the KU63, which is cheaper, but only has one level of PAS (maximum). If you get the S06P, you have to order the LCD and the wheel-speed sensor as well.

http://www.bmsbattery.com/controller/415-hall-sensorsensorless-250watts-brushless-hub-motor-controller.html

You can choose the type of connector on the charger. Post again if you need to know what to type in the other options boxes, but you need to say which battery you have.

£47 for the charger and KU65 including delivery.

ya my battery and throttle are fine,i was looking at a controller on bms but i dont think theres enough of the round connectors on it,theres only 3 and mine has 5.and the controllers that have all the connectors on that site are torque simulators so they wont work with the led panel






KU65 250W 6Mosfets Controller

You only have to connect your motor, throttle, PAS and battery to the KU65 and it will work. You will have to solder a couple of connectors, like the ones on the battery. If you don't want to change any connectors, you have to get a replacement controller from 8Funbike.

You don't have to worry about the colours of the wires. The functions are the same.

No. They call it a jack plug. Just write "jack plug for bottle battery"
The charge voltage is 42V
Battery type: lithium bottle battery
Charge current: 2.5 amps

No, you want 230v UK plug.. If you didn't specify,send them an email.

You'll have to change the connector at the controller end of the battery lead. They provide it for you. You'd need to show me the connectors on your throttle, PAS and brakes to comment on them. Even if they're the same,you have to check the colour sequence is the same. Sometimes you have to swap the pins over on the throttle or PAS.

Hiya!
I'm a disabled cyclist and had been looking for an electric trike for ages, contacted many of the UK distributors of e-bikes but with no luck. I was looking for something which didn't look like a delivery bike, was quite powerful in terms of motor and battery and would cope with the hills down here in Cornwall.
I just happened to latch on to an online chat with 50Cycles from Loughborough and the MD said that they happened to have one in the corner of their warehouse!!
To cut a long story short, the trike is a converted Kalkoff Agattu with the conversion having taken place in Norway by a company called Abu_Rehab who specialise in rehabilitation equipment for disabled people. They designed a fantastic conversion and have the parts manufactured in Japan. It does not look like a conversion with wires hanging around all over the place and utilises a top end e-bike as it's 'donor' bike. For me wanted a reliable machine as I couldn't afford to have a mechanical failure as I would be stuck but the conversions I had looked at in the UK looked as if they were a compromise - which of course any conversion is! If anything, it is very heavy and with me aboard, going downhill is somewhat of a challenge as it can be very fast therefore, whilst it has a mechanical disc brake on the back, I about to upgrade this to a hydraulic disc brake. Of course transporting the machine around is very difficult but on my next car I'm having a tow bar to which I'm going to fit a rack which will then spread my experiences further afield.
Abu_Rehab have a website which is worth looking at and I am happy to share a contact name there if you wish. I can also show you a couple of photos if you're interested too.
I have to say that I did an aweful lot of research into the subject and was beginning to think that what I wanted was not available. You have to be prepared to compromise a bit and to spend a bit of money on quality but am happy to help if I can offer any more of my experiences.
Good luck
