This really helped me, I had no idea what to even check and Jonny , you put it in perspective for me and it was my brakes. I got my e-bike working because of you. Thank you so much
You Sir, are a legend. Had my Kalkhoff booked in for what was going to be an expensive repair. Checked all connections and the head up display wasn’t quite connected properly so the motor wasn’t connected to it! All back working now thanks to watching your video and listening to your advice.
Thanks man! You helped me out with my issues only three minutes in. My bike was throwing a brake error code. Disconnected the breaks and it work beutifully.
Thank you so much! My power assist and throttle weren't working this morning and this video gave me the solution I needed - The magnet on my hydraulic brakes had shifted. I screwed it back on and it worked perfectly again!
I wanna thank u , my boyfriend has an eco motion electric bike ,and it just stopped working , and I seen ur video so I showed it to him and the first thing he tried , it worked .
Thank you for your tips and advice. Your a big help. Am new to the Ebike world. I had a bad brake connection. Where it wasn't allowing my display screen to come on. Thank u again. A fan from here on out
Hey Johnny, john e. here with a thank you for helping me to diagnose power loss due to a loose connection between motor and rest of bike multi-pinout connector. Must have worked itself loose.
@@elijahkuti9294 What I did was unplug the cables and plug them back. I don't know if that will work for you.My advice is keep watching videos or go to a local bike repair shop for help.
I was all bummed my bike crapped out and was looking for more technical troubleshooting, thought what a worthless video, Duh who wouldn't have checked their connectors and cables, stoopid! Been through the continuity testing of the mosfets, etc. I totally thought I wasted my time watching your video! Decided to go back out in the garage and check all my connections... Eh, you nailed it brother! I'm eating crow. Sure enough the axle wasn't quite tight enough so it spun a bit and kinked the cable that goes through it, I straightened it all out and she fired right up! @JohnnyNerdOut for the WIN!
We bought two Lectric XPs. If yours arrives and works out of the box count yourself lucky. If it does not you'll spend a few hours underneath a brand new bike following emailed trouble shooting guides. If you fix your brand new bike you're lucky again because it's a high hurdle to get Lectric to get a new, working bike sent to you for the good money you've already paid. Things happen, we all understand that. The true measure of a company is how well it puts things on track, and makes a customer happy when things do go wrong. Lectric e-Bikes has a ways to go on this count. Be advised.
Hello, maybe u can help me please. I have a daymak EM2 2020 and the bike will not shut off. Have to use the breaker. U know why?? The bike runs great .
thank you Johnny. I just removed the broken brake cable plus some small components, and while just started to riding the biycle, I pressed the brake and suddenly no throttle. I opened the youtube immediately, watch your video and you mentioned something about the brake. I reinstalled the brake component... whatever it is called in place, and walla, the bicycle ran again.
I adjusted the brakes on mine, took up the free play on the levers with an allen key, and unwittingly activated the cut off to the motor !!!! When you pull the brake lever, it cuts power to the motor for safety, by adjusting the brakes a little too much, the cut off switch was permanently engaged. Just backed it off a little and all was fine.
Thanks for the video! In my case the situation was the battery tabs, after 700km my girl friend Bird bike started acting like intermittent power, I use a very small flat head screwdriver to push the tabs back and it looks like fixing it. I notice when the bike is getting a bump we observe the issue, I guess the frequent bumps make the contact to be loose. I now use a velcro strap to tie down the battery, hopefully it might help.
Hi Johnny. I got the isinwheel M10 Commuter Ebike only 10 days ago. My battery is fully charged, the problem is when I turn the throttle, the motor just lurches for 1-2 seconds then stops. If I get off the bike and lift the back wheel, it works fine, but when I sit on it, the motor stops after a second. I'm only 130lbs and the specs say up to 330lbs, so its not my weight. any suggestions?
I bought an e-bike with the same interface about 9 months ago and recently it randomly stopped going full speed of 50km/h and only reaches a top speed of 24.5 km/h. What could have caused that and what can be done to repair it? I tried to reach the company but didn't have any success. They stated that I needed to reset the bike and gave me reset instructions that didn't work. I found a video on YT instructions for a reset which worked to reset the bike but the speed problem remains the same. Any suggestions? Thank you!
You are THE MAN! My RADCITY lost power about 5 miles down the trail. Had to hump it back to my car. Spent some time checking it over. (What do I know about ebikes?) Watched this video and where you talked about the brake cutout got my attention since the power failure happened right after I applied the brakes. Went and checked out the rear brake lever and noticed that somehow the throttle cable had got caught in the brake lever opening. Releasing the brake lever was squeezing the throttle cable. Worked it loose and bing-bang-boom. Back in business with full power! Thanks so much. Like to buy you a beer and a good cigar.
Have a friend with a 2019 Rad City. Lost power. Rad tech support sent a new controller. Nope. A new wiring harness. Nope. New throttle cable. Nope. Got to be the battery then. Can't get batteries right now! Sorry.
Excellent video. Leaving the battery on the bike for charging protects contacts. Chaining up the bike to stop it falling over , also protects contacts. Cheers mike
Got my bike delivered 2 days ago. I rode it to work that evening a little over 2 miles. Cruised around for maybe a mile on my break. It turned on after leaving work to let my coworker test it out. Later that night, it wouldnt turn on. Then today it did. I repeated the exact same cycle as i did yesterday except i was the only one who rode it today. When i got out of work, it wouldnt turn on again...will definitely use your tips to investigate tomorrow but im lost at how i did no troubleshooting and it turned on this afternoon
Question: my ecotric rocket is 3 years old and recently the motor always operates at approximately level 4. It has 0-5 levels. But even at level 0 it runs up to 17mph as if it's in level 4. This happened recently I believe after a rear tire change.
Our Aventon Pace bikes were flooded in Ft. Myers Hurricane Ian. We rescued them the next day and washed them off. The batteries were destroyed. Took them to a bike shop....they cant get them to turn on and advised trashing them. Any thoughts on how to proceed? They are just trying to get us to buy a new bike.
Johnny love your videos. I have a question on a new build with a bafang 750 mid drive. Everything seems to be working, but only for like 1 second then motor slows way down, if let off of throttle when hit I again get full power for about a second then it cuts back to barely working again. Any help would be greatly appreciated , I do have another bike with all the same parts so I will change 1 piece at a time to try and find the problem but you might have seen this before.
My custom built e bike died when I was braking the regen came on for half a second then gone I look down to a blank display it will not power on anymore the battery is fine and at about 80% -85% charge my 12v system gets it's power from the controller and all the lights work just fine. I've only done limited testing on the controller but I think it is the display because the on/off is connected to it and if turning the key off cuts power to the display then that on/off button may do the same.
Hi Johnny, some good advice there. Yet although I think my issue is probably simple, I found myself without options. I have a Skott-E Sub Tour, the controller displays everything except the speed indication, so I naturally check that the magnet on the back wheel is in-line and that the battery is ok. I hang up the bike to test the speed, yet still no graphic or indication with the large speed info? The controller seems to be fine, yet wonder if an internal battery in it is low on power? Apart from this I have no idea, I also checked the wires. Any tips? 🙏
What if the key lock component is housed separately such that when the top cover four screws are removed, the key lock component is residing in a separate compartment housed in plastic cover adjacent to the main plastic casing? And battery is slided into the battery holder bracket of the ebike?
Great video. Hi I'm Lg. . I have a Haoqi H1000. My voltmeter says 52 but the button on the battery that shows how much power high and low is not working ... Is the battery good but that power light stopping the bike from getting power. Please any suggestions
Hey my battery sparked but on the other side where you you plug it in to charger Looks a bit fried now won’t go red to charge Is that a easy part to fix?
Thank you. I didn't know that the brakes had shut offs. I had disconnected my front brake cable and didn't have a spare and tried to ride without it. Put a new cable on and presto. You da man!!!
My Astro pros hydraulic disc brake sensor got chewed by a puppy. The bike turned on once after that but once powered down it will not come back on you think that sensors the issue.
Is it easy to change a hail long 20ahn cradle replacement ! Got same connectors only worry about connecting to main line power lines got one red wire and the normal black red connector ! For BAFANG 1400 watt midrive BBSHD Same as the original it came with ! If possible what is the red one with no connector please ,do I rewire the red one the others have connectors ? Thank you !
Can I ask about the k800 fat bike? I just swapped out the display because the other one. The screen was half burnt out. It's the M5 e bike works with the old display as soon as I put on the new display the bike does nothing. I've adjusted the setting and still nothing what am I doing wrong
Mine gets error 16 so cuts when doing both breaks and it only supports in a certain gear also its a brand new bike . Replaces many things including the speed sensor and new shifters but still acts like that?
Thank you for your time, info and expertise. I have a Rambo G3 750 bafang. I'm having problems with the controller turning off during operation typically under a heavier load or uphill. My battery connections seemed good and my voltage is good on my. Do I need to check and likely start by replacing the controller in the motor
I have a Phantomgogo R1 36v scooter. When I tested the 5v red wire coming out of the controller I found that the 5 volt Red Wire is pushing 17.44 volts. I am afraid of connectiing the.controller to the throttle because I do not want to damage the throttle. Is this high voltage normal or is it a defect? Will it destroy my throttle?
You may have an idea about what I'm experiencing. I have an electric bike that shuts off after a few seconds of riding. In both cases, using the pedal accelerator or the throttle control button, it happens. The bike display indicates the battery is full and there are no issues.
I am having the same problem. Another channel suggested taking the battery off and adjusting the connector prongs on the base of battery so connectors would fit more tightly. I haven’t tried it yet, but am hopeful it works. Let me know if you were able to get yours working again, please.
I'm having similar problems, I lost power assist but still had throttle. So checked my sensor and magnetic ring. Swapped out sensor for a new one and didn't work. Yesterday i went a mile down the road and it shut down. Powered back up with full display but touched the throttle and it cuts out. Motor is fine, display, battery is good and all cables are good. It can only be the controller.
I bought an ekxbike x-21 and the motor makes a horrible sound when the throttle is engaged. It sounds like gears grinding Any idea of what would cause this?
Hi I have an AOSTIRMOTOR so7 and have an error 30 code now, checked everything and still won't work, I know the speed sensor is messed up but the bike was working still with that cutting on and off at times, but man 4 days now and I cant figure it out! My only source of transportation too!
My wire burst short circuit and try to reconnect the fine 5 wires but it didn't have power. What shall I do . Does it have fuses somewhere . My Bafang display is C965
Hello, I have no idea what it could be, but my fat bike (ouxie v8) is working perfectly, charges well and everything works, etc. until the battery drops below a certain percentage, approximately after 15 km of riding, then it still shows on my screen It seems to have around 46 volt output, but as soon as the support starts working it cuts out after a second and the lights that indicate how full the battery is no longer work, I have never actually had this problem but it came out of nowhere. Do you know if something like this can be solved and if you have any tips, that would be great!
johnny I need help, i have a new battery that wont work but the old one still does. Bought from alibaba it puts out correct voltage and polarity is right, still cant get it to power on bike.
I have a rear motor on my ebike. I was riding and my brake line to the back wheel snapped at the lever, then the motor stopped working. I'm going to try what you said about disconnecting break cutoffs and see if that fixes the problem... will report back...
So I followed the wire from the handle bar to the control box and disconnected the wire and IT WORKED! Thanks! I didn't even know about break sensors until now...I thought my motor went out....AWESOME
Hi Johnny I've got a Cyrusher Ranger, great bike but pedal assist has stopped working. The bike rides well on the throttle and cuts out when I pull the brakes, so thats OK but just doesn't put any power assists down when I start pedalling, I wonder if you have any idea what that could be? Thankyou Sandy
Hi. Maybe you can help me troubleshoot. I have a converted e-trike with an MXUS motor hub that uses a 52v battery. Recently, any time I'd ride it, the e-trike turns itself off, then I turn it back it turns off again, then I turn it back on but won't come on unless I press the button 10x. Then it will come back on but none of the sensors work, then it just dies completely. To get it to remotely work again, I have to unplug the battery then replug it in, but it will not stay on long. The batteries are still good, (trust me, I spent $600 on a brand new battery and it's still doing that), they're fully charged, the voltage is fine, and so far the shop that did the conversions have found nothing wrong with it and it works PERFECTLY fine when they use it, but it immediately starts doing it to me when I bring it home. I tend to ride it at max speed, but this has never happened before, and even when it's not max speed it still does it. Is it something wrong with the hub, the motor, the display, the wiring? I need help figuring this out because this trike is my ONLY mode of reliable transportation.
Can you help me? I checked all my connections . My display won't stay on. The bike is brand new out off the box. Think it's just the display needs replaced?
I have a jetson bike with a problem where it only stays on if you hold down the power button, it gives a little power up animation on the battery display but it turns off if i let go of the power button
Hey Johnny, thanks for all your vids mate, there gggggreat! I'm in the UK Newcastle upon Tyne, I've made my own ebike from an old trek mountain bike, I love it 24 mile a day. I've done 1100 miles on the bafang 750 watt. Today it has come up with error 12 motor kept cutting out then working again, did a weird peddly juddery thing. I did the off and on again thing and it worked then stopped. Finally I realised that the throttle would still work with out any problems. Luckily I had enough charge to get home on just throttle any ideas. It's really wet and muddy my bikes getting caked everyday I'm hoping it's some water in somewhere causing havoc???
I have a small electric bike that is brand new that will not turn on unless it is hooked up to the charger. When I have it plugged in it will turn on and it shows a full battery and horn honks but no throttle. When unplugged nothing will turn on. Totally dead. Any advice??
I got the bike yesterday road it for about 15 20 min. a few hours later tried to start it and nothing no power ,no display nothing battery full charge any help please
Was riding bike shut off pit battery back on sparks shot out the bottom piece where the power and ground weld into metal plate popped off is that my problem
I have Raleigh Stow E Way. There's something up with the power, it comes on then it stops afrer about 30 secs and sometimes it won't come on at all. Was this the same problem you had?
My e-bike is showing error code 10 and I don’t believe I have to replace the lcd screen what should I do next I unplugged all the plugs that show on the bike itself
My issue is the pedal assist surges, this started just recently. I bought bike new last year but when using full throttle mode, runs smooth. I have not unplugged brake sensors yet.
I have a yose power with an error 09 and have replaced the display still the same. I’m going to wait until weekend until I start breaking down the kit.
Help...Brake light wont come on even with headlight on. Error 25 came up for just a second then went away and we noticed the rear brake light didnt work at all. I checked the wires into the brake light and also unplugged all the brake light Leeds and put them back on, still not working. Bike runs great with no error code now but brake activation or headlight turned on there still is no NO BRAKE LIGHT Thoughts? Guess I need to see if the brake light itself went out.. Himiway Bike has 5 hours max on it... The nubbies are still on the tires.
Well I did a volt check to the rear light and NO POWER. Again checked all the leads and all connection pins look good... Himiway wants a video of the problem. I think this is their way to make me go away.... Why a video, brake light doesnt work when brakes are applied or when headlight is on. Give my a solution to the problem or another place to look!!!!!!!!!!!!!
I was putting a 1500 hub motor on my cat trike. I turn the monitor on and was in the middle of putting my past word in when my phone rang. My grand son pushed the led pad buttons and it put a pass word in and I don’t have a clue what it is. Now I can’t get in. Do I have to buy a new monitor. Or is their a code I can put in. I bought it on line and the company I bought it from is no help. I don’t know why I put a code in anyways. I have to trike one is mid drive and this one has a hub motor. Can you help me or point me in the right direction
Thank I was having problems today I fixed my popped tire once then went for a ride and bike stopped running I seen ur vid and it was the disk brake then once I fix that I get on n my tire popped again
Please reach out. I have a velimotor Vmx 12 electric dirtbike. I charge it fully. And turn it on. It stay on for 1 minute. And the battery dies. The led display stopped showing anything after a small crash. I checked all connections. And visible fuses. I am having a hard time finding parts or someone to work on it. I’m not an electrical guy. Please help. I would be interested in sending you the bike or figuring something out. Please advise
