October 16, 20205 yr I need a Bigstone C300 Handle bar display (controller) I have searched eBay and emailed Bigstone with no success. I was wondering is anyone breaking a Batribike Dash or any other ebike with a C300 handlebar display type C300-1407-A979 36v. Or is there a compatible unit that I could just plug in as I am a mere rider with no technical know how.

You can replace both with an equivalent set for less than the price of a C300, or you can pay a bit more and get a much better system. The C300 is made by Bigstone. Most likely, any of the common Bigstone LCDs will work, but I never tested that.

October 17, 20205 yr My C300 has three connectors and not the same. It was used with a hall sensor Lishui controller A throttle 3 pin Julet, male pins. A 2 pin brake . A 8 pin trunk cable julet, male connector (yours has female connector) this is different from your 8 pin connection as it doesn't have the 8th center pin but 8 aroud the circumference.
October 17, 20205 yr You can get your bike working on throttle and PAS1 by cutting off the cable from the LCD, then strip back a bit to find the red and blue wires. Either put a switch between them or twist them together. That should keep you going until you find a replacement LCD. Brainpower with LCD is about £40. It works more or less the same as what you have. KT controller and LCD3 is around £70. It's much better than what you have. The motor will be smoother and quieter and the power algorithms are better. Both controllers require some rewiring and some adjustments of the LCD settings. Do not try to save money on a cheaper LCD for the KT controller. You need a good one to get access to all the settings.

Could you recommend the best place to purchase the KT controller and LCD3.

To install a controller, you need to understand, you need very basic knowledge of wiring and you have to be able to solder. These things are easy to learn, but if you're totally ham-fisted and non-technical, it might not be a good idea to tackle a job like that on your own. Topbikekit or PSWPower are probably the best places to buy a KT controller http://www.topbikekit.com/t06s-24v36v250w-torque-simulation-sine-wave-brushless-controller-for-ebike-p-443.html http://www.pswpower.com/ven.php?cargo.2016-3f-47ma

Can I ask for just a little more help with my order. On the Topbike web site there are a number of drop down boxes (screen shot attached). I have changed the display to the LCD3 display but could you advise what other alterations I need to make to the remaining boxes. I will try and remove the existing controller tomorrow see what size of a recess I have.Topbike Screen Shot.pdf
October 17, 20205 yr It would be a good idea to get a speed sensor in case the one in your motor packs up, and I would get an 8 pole PAS as well, just in case. They don't cost much when you buy them with the controller. When the controller comes, ask again, and we'll show you how to connect it. Don't start until you've had help because there are some hidden pitfalls.

There are a couple of other drop down boxes which I need to complete. What do I need to set the Brake box to as the brakes are just conventical bike brakes and do I need the HWBS. I think I will also get the throttle for all the extra cost as I have an existing hand throttle.
October 18, 20205 yr Author HWBS are inline cable brake sensors - not needed. Thumb throttle is the best, what about the drop down box for brakes do I select with normal brake?
October 18, 20205 yr what about the drop down box for brakes do I select with normal brake? Don't you already have brakes with switches?
October 18, 20205 yr Author Don't you already have brakes with switches? Yes that was the second smaller cable coming out of my C300 display.
October 18, 20205 yr Yes that was the second smaller cable coming out of my C300 display. That's a shame. You'd have to cut off the connectors and extend the wires down to the controller, or you can buy a pair of the crappy brake levers with the controller, or you can buy one or two HWBSs. They fit on the brake cables. You have to cut 2" off the outer to make room for them, or you can forget about brake sensors because they're not really needed with a KT controller.

More wire connecting is the connector to the controller readily available.
October 18, 20205 yr More wire connecting is the connector to the controller readily available. Yes, but I always cut them off and solder the wires. I'll use connectors if they match because I'm lazy, but if the connectors don't match or the wires are in the wrong sequence, it's much quicker and easier to get rid of them.

Thanks again for the advice about to place the order i will be in touch again when the unit arrives.
November 6, 20205 yr Controller arrived this morning ready for install tutorial Start by connecting the LCD, the battery, the motor and the throttle. make sure that all wires match colour to colour on each side of the connectors. Do all this before routing all the cables and tying them down. Next, switch everything on and test the motor with the throttle. If it doesn't go or runs rough, do not hold the throttle open and do not open it fully. Report back when you get that far, and I'll give instructions on how to deal with the PAS and speed sensor.
November 6, 20205 yr Author Are there any drawings available which identifies the Various wires coming out of the controller or is it best to trace the ones from the existing controller to the various parts
November 6, 20205 yr Are there any drawings available which identifies the Various wires coming out of the controller or is it best to trace the ones from the existing controller to the various parts On the website listing.
November 7, 20205 yr Author Just checking on something. When I opened the wire from my existing controller to the motor I discovered six very fine wires in addition to the three larger diameter wires (blue green & yellow) marked as motor wires. Would I be correct in assuming these are what is referred to as the Hall Sensor on the drawing which you referred me to as they are blue, green, yellow, black, white and red. I know you haven't said to connect this yet but I was just wondering if my assumptions are correct.
