You will need to buy a KT-LCD3 display as I’ve never been able to get the SW900 to work properly with a KT controller. Here is a link to another SW900 manual. But … it is just human nature–things should work they way they are designed and marketed. I Used to be well into bikes in my younger days and a few mates have been banging on about the ebike revolution so I thought I would build one. C1 relates to the amount of magnets on the PAS sensor disc – if this number is wrong the PAS won’t work. Hi Tony I have a 1000w voilamart kit with pas and twist throttle incorporating a small useless display. I have the 1000W Voilamart kit. The motor axle can sometimes be a tight squeeze to get into the dropouts. Excellent value for money – I bought it for £120 a few months ago. I’ve had exactly the same issue with the Voilamart kit and SW900 display. You should be able to achieve up to about 40 km if you use the lowest assist level.

Hi I must say everything you’ve written in this article is 100% accurate. You’re a life-saver! I’ve always purchased my 1500w KT controllers from Pasion ebike on Aliexpress, they usually deliver within a couple of weeks. The only other place I can suggest trying is Aliexpress – I find most things turn up within a couple of weeks when ordered direct from China. You should be able to use the PAS and throttle simultaneously on the Voilmart. CE certificate is to ensure the product meet basic requirement (legal requirement to sell any product within Europe and UK). Olá, Parece que seu painel de exibição pode precisar ser configurado. I’ve tried changing the parameters (according to a thread on Endless-Sphere) but the amount of power always remains the same in levels 1-5. I sounds like you might have a faulty PAS sensor, or the distance between the sensor and the magnetic disc is either too close or far. If I set it to 75kph, it seems to restrict the power so that it won’t go much above 15mph, but it seems to do that by restricting the power the motor can draw which means it’s not so good on hills again. Thanks for the compliments, much appreciated. I managed to sort it out by purchasing a separate KT 48v 26A controller along with a KTLCD3 display – using this combination I could get the power levels to correspond to the assist.

Also, if there was no PAS sensor/magnets on the bike should the throttle still be working with the P10 setting set at zero?

Even if I choose setting 1 I can still use the throttle, whatever setting I choose I can only use throttle, Is there a way to factory reset? Hi Chris, The black wire coming from the controller is the battery negative wire and should not be connected to the green phase wire. Will try to get crank off so I can install PAS. Whatever setting I choose I’m not getting any PAS. What I usually do if this is the case is either solder and heat shrink the + – or change the connectors to something like an XT90.

There is another connector (male) with matching colour wires black white and red (same as pas sensor) but this relates to a speed sensor in the instructions, any ideas where I might be going wrong. You don’t need an LCD display, as long as the kit has the throttle control with the on/off button and a 5-pin connector (for the controller) you should be fine. And where I can purchase one? Hi Tony, I have a voilamart 1000w kit with a 26A controller, but i find the pedal assist very poor. These offer very little in the way of resistance (and extra weight) when compared with a DD motor (which is like pedalling a tractor!) I connected yellow to yellow, blue to blue, black to blue green. A good starting point for a battery would be a 48v 17.5Ah battery with a 30A BMS. The SW900 display should plug straight in. Hi Tony I have this kit, but the 500w version. It’s a simple, low-tech solution to building your own ebike. That’s why I eventually moved away from DD hub motors and went to mid-drives. I have installed at least 50 of these kits over the last 3 years, and I have only ever had a couple of long-term issues reported off customers. What does the red button on the throttle/display do?
