controller

I have had a Giant Prime e+ 0 for three years now. Since last week I’ve encountered the problem with the second bar of the battery blinking and no assist through the motor. Does anyone know what this indicator means? There is no fault code in the left hand of the screen. Thanks in advance

Hi all. I'm wondering if anyone can help with something. I picked up an ebike (Smartmotion Essence) and need to figure out what parts I need. It has a c500b display and a 36v 250w front hub motor. The controlller isn't working and I am hoping I can just replace that but got confused by the KT...

Is it possible to switch battery and/or controller for my swytch bike pro 2nd gen? The reason I need a change is that the connector from my controller to my battery melted yesterday while biking and swytch customer service wont send me a new controller, they only want to sell me a new conversion...

Hey folks, looking for some technical advice here. I have a 5 year old Hailong 1 battery mount/controller that is on the blink. Getting short circuit warnings on the dash. I've swapped over components with a friend's bike and everything seems to work apart from the mount, so I'm guessing it's...

My dad has a Czech electric bicycle to be repaired in which the display is damaged. He has a second display and controller for it. Unfortunately, cheaper and slightly different. So he thought he would replace only the display itself. Only that the old one was connected to 6 wires and the new one...

Hi all, I started my search for an e-bike a few weeks ago, and every time I think I find a good option, I come across something to sour me on that brand or some new option that looks better in comparison. I'm a newbie, so in truth I don't know exactly what would be best for me, but I do have...

I've bought an e-bike several weeks ago, and it kept turning its motor off whenever it gets to 25km/h. I've googled the way to remove the limit but the resolution doesn't work which is to press both + and - at the same time to get into the setting mode and then change the number. I assume that...

Hi there, I've recently finished building my 13s 3p battery with Samsung 25r 18650 batteries, which has left me with a voltage of around 45v when charged, When first built I managed to ride 200m down the road, before it all suddenly went black... I returned home and put the battery on...

Been searching the web for hours scratching my head trying to add a throttle to my bike and bypass the speed limit. Is the black 3 pin connector assigned for throttle? (grey, black, red) If so, why is the order of the colored wires different from the one I am looking to buy? Also curious what...

Hello, I have a Sava 20" wheel folding ebike 36v 250 w rear hub motor, which I got on the slow boat from China it has a carbon frame and I have had it since September 2020. It has been a great bike but recently the PAS system stopped working. The sensor was damaged so I replaced that and the 12...

Hi gang, hope all is well with you - was wondering if anyone would be able to offer some assistance? My wife's much used GTech city has had a problem with the battery for a while. The battery is the one with the digi display on it - V2 I believe. One of the the connectors in the base of the...

Hi I have just converted my MTB with a Chinese 36v hub motor kit and a KT-LED880 handlebar controller... I am using some old batteries from my previous e-bike, including one LiFePo4, 12 cell, which I am getting at rest voltage of 3.32v per cell and overall 39.9v. This does not work on the...

Hi everyone, I just got my Samebike and I am over the mood to be joining the Electric bike gang. I have two settings that I would like to change but they seem to be locked and was looking for advice how I can change them? 1) I would like to change the P12 setting up to level 5 for the 'Pedal...

Years ago I bought a second hand e-bike in pretty bad mechanical condition for dirt cheap. I did all the repairs and it's been running mostly fine all this time, except for intermittent waterproofing issues, specially during the winter. Unfortunately a few weeks ago the LED display finally died...

Hi everyone, I’m developing my new BLDC controller for Ebike and I want to share with you some of my progress, I have been working on the pedal assist system based on the cadence sensor and I tried to improve it and make a new Pedal assist system. This new system will scale well to your input...

Hi :) I have just replaced the battery (and holder) on my wifes cargo/kids ebike. I removed the old battery and holder, and did at temporary connection (before screwing things into place) of the new holder, battery, cable connections etc, and everything worked great. (yay!) Then I messed up...

Hey guys, Just getting ready to install a bbs02 and starting to think about security. My bafang display -(and most others from what I can tell) are not easy to pop off and put in your bag when you leave your bike - like say simple bike lights are. It would involve unscrewing the clamps of the...

So I got your attention, that's great! First and foremost: this is a TRUE story, as weird as it may sound. I searched the internet, contacted the company (thanks, David Hou @Samebike, for ignoring my support request!), nobody ever mentioned what I experienced. Then I asked for help in a German...

I bought my first ebike kit 2nd hand last year and I've been using it every day to commute to work and love it to bits. The kit consists of a 36V 9Ah battery, Crystalyte 408 motor and Crystalyte 36V 20A "Journey" controller. Unfortunately it let me down this week, the motor started stuttering...

I'm currently injured and won't be able to cycle for a while, so I've been looking at buying a fairly powerful kit (using mainly throttle only), when I remembered that I have this old kit laying around (see attachment), and thought I'd have some christmas fun and turn it into something a bit...
