How to Troubleshoot and Fix an Electric Bike

[@dakotalujan7503]

I'm in a small town with no bike shop around. I need to get my electric bike fixed before my first day at work tomorrow otherwise i'll be sweaty all day. After watching the video through I found the easy fix was the last tip at the end of this video! ha Saved my day! Thank you

[@dougjohnson3128]

Hey just after a few mins of listening I figured out my ebike battery problem...Thanks alot for the help

[@ericspringer5359]

Best Video for troubleshooting E-bikes. I just got mine 3 days ago and tonight was the first time where I had to fold it up and transport it. After taking it out the bike wasn't working. I tried everything from checking the wires multiple times to checking the fuses, the battery...etc. I was running out of options and frustrated. After watching this video, I made it to the 3:41 second mark until I realized it was the brake! Super helpful! Thank you!

Hi Check battery connector that solder wire diffused to battery

[@hy5trucking464]

Thks my plug was loose under the bike, now it’s working on my folding bike… Thk you very much👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍💯

[@officialtechin5]

Honestly I miss these videos. Sam is one hell of a character. Cheerful, and had a talent for making relatively complex mechanics/concepts sound effortless. In other videos, hearing how he goes the extra mile when service, if I was anywhere close to the region, I would stop by. C, bring these videos back man. Keep up the great work!

[@wnishio13]

The last tip of checking the connection right next to the motor sorted my electric bike! Thanks so much for your video! 🙂

[@jamesbfryejim3790]

Thank God there's ebike shop's on KZbin to help people like me to troubleshoot certain things cause I don't have any place we're I live that can help me thank you for the info. 👍

[@Dj7Baka]

This video helped me repair my new ebike. The manufacturer's documentation failed to help out but this video told me where to start looking/troubleshooting. Within 15 minutes I had my bike up and running for the first time.

[@ceyhunbayram6880]

what was the issue?

[@mbkahix]

This video saved a trip to the repair shop for me. I have a five year old Genze. The company folded up almost 2 years ago. What to do? I recently had the original battery rebuilt. Had power to the LCD, but bicycle no go. After watching this video, I checked the motor shut off, which looked a lot like the one pictured, under the hand brake. Lo and behold it had come a bit loose and was shifted sideways maybe a quarter of an inch. I put it back where it belonged, tightened the screw and voila! I'm back in business. Thanks much!

[@karlschwab6437]

This is a great guy for the ebike business! I'm here in Michigan, so unfortunately, I can only see you work with him in your videos, but let him know, that he is appreciated here in Michigan!

[@eman59461]

This video saved me hours of time and helped me learn more about how ebike works and troubleshooting . You explained it very well. great job. Thanks again.

[@ForbinColossus]

First time I've seen an electric bike lift. Love this vid, Court. It's like a basic primer for new e-bike owners when the durn blasted bike won't turn on...

[@sergeydzema5569]

This is just superb, I been tryin to find out about "proper bicycle maintenance" for a while now, and I think this has helped. Ever heard of - Viyackson Yenacob Review - (do a google search ) ? Ive heard some incredible things about it and my mate got great success with it.

I habe a ebike hope battery not charging

[@mariarocha2490]

I have a ebike and the battery is nor charging

[@colinwatkins2950]

Well done sams bike shop, my ebike wouldn't power up,i watched cort and sam on KZbin and learned my bike had trouble with the battery not connecting with my controller.as my ebike is a folding bike I think there is a problem with the open close folding of the bike this could be a problem with folding bikes, don't fold up your bike too much.I'm from England and I learn a lot from sam and cort.

[@MrMotown2011]

*Excellent, very informative!* The video features a discussion at Myron's Xtreme Machines in Fullerton, California, focusing on troubleshooting electric bicycles. Here’s a summary of the main points covered: 1. Battery Check: The first step in troubleshooting is to verify that the battery has enough voltage. A voltmeter can be used to check the voltage directly from the battery or via connectors. A fully charged 48-volt battery should read around 52 volts. 2. Connections: Loose or bent prongs in the battery connectors can prevent power from reaching the bike. It's important to check these connections for proper contact. 3. Brake Inhibitors: If the bike powers on but doesn't function, the brake inhibitors may be causing a cutoff. Inspecting the brake levers and ensuring they are not bent or misaligned can resolve this issue. 4. Wiring Issues: Tracing wires to check for disconnections or damage is essential. Problems with the throttle, pedal assist, or cadence sensors can also prevent the bike from functioning properly. 5. Torque Sensors: Advanced bikes might have torque sensors that can malfunction, leading to issues with pedal assist. If adjustments don’t work, these may need to be replaced. 6. Maintenance Tips: Regular maintenance is crucial to avoid problems, such as ensuring all parts are tight and properly assembled. This includes checking the bottom bracket and keeping wiring clear of pinch points. 7. Professional Help: If troubleshooting at home doesn’t resolve the issue, seeking help from a local electric bike shop is recommended, especially if the bike is complex. 8. Safety: Wearing a helmet while riding is emphasized as a critical safety measure. Overall, the video provides practical advice for diagnosing common electric bike issues and highlights the importance of regular maintenance and safety precautions.

Tons of help thanks right break was faulting, disconnected and works now.

[@nerdexproject]

Very great! The fact that my local bike shop might be not able to fix e-bikes was definitely one concern so far but I think sometimes you might be even able to fix it yourself! Good video!

[@johnhep2671]

Thanks so many basic but important checks. After watching i fixed the problem I've had for months. Thanks!

[@tonyjackson9992]

Great video, I swear that is so detailed and so easy to follow I have had an e-bike two weeks and learned so much in one sitting. I'm excited to have a working bike soon

[@GearSpot26]

6 years later and it just saved me allot of time and money.

[@cboyyo9670]

You probably won't read this comment. But I can't thank you enough for this video. I have an ebike kit that hasn't work for a while. I have been trying different methods, spending lots of money to try and sort it out, brought the wrong wire connectors etc. I got to a point where I almost gave up. But when you mentioned the brake lever being ever so slightly pulled, I check mine and where you put the cable, that was stopping it from being fully closed. I can't believe after all that money and that was the bloody issue.

[@40footgiantowl]

Thank you guys so much!!! my back brake cable had come loose so it was turning that safety cut out switch on. all fixed now. Thanks again!!!

[@nigelwatts9312]

Fantastic video, I just fixed my pulsing almost no current ebike, magnets were dirty and the disc they were on was out of place and on an angle, would have never thought of that before watching your video, thanks heaps.

[@robdemytruk]

Thanks for the info, I managed to get my 14 year old neighbours bike going for the first time in a year, great info..

[@cawb4751]

The local E bike bike shop in my area refuses to work on any ebike unless they sold it to you. Thank you Frankfurt bike shop in Gerard Ohio.

[@nathangannon5933]

Yes. Most bike shops in my area dont even want to touch my e-bike. I live 2½ hours from NYC and that's the nearest e-bike shop. So I just bought a new bike. I'm gonna look it over after this video and see if it's a simple wiring. Thanks for tips

[@ksingleton101]

Thank you, Thank You Thank YOU, I just crashed my Sondor's today and bent the front fork forcing the front wheel into the frame. The front tire was pushed so far back I couldn't steer at all. I was able to turn the handle bar around in reverse and steer but I had to disconnect the front brake at the handle bars to make a 190 degree turn of the handle bars. By doing so I didn't realize until I watch this video that I cause the Brake lever to disconnect the Brake Inhibitor Switch and there for caused the motor not to work. It did work for about 100 feet but then stopped. Because I bent the forks the tire was rubbing and causing what felt like breaking, which I thought I might have damaged the motor because of over heating. That wasn't the case, once I fixed the Brake Lever everything works fine. Everything except the front Fork, it will need to be replaced. Thank you for making these very informative video's.

[@j.m.1382]

This just helped me with an escooter fix. Thanks for posting clear and knowledgeable videos.

[@moiing]

Thank you very much for the video. It’s super practical and useful!!!

[@ElectricBikeReview]

Sure thing! I'm glad that you enjoyed it, thanks for the positive comment :D

[@cooloutac]

I watched this video multiple times. Golden.

[@everettdurst1]

Thanks guys. Glad to see this kind of advocacy. I can't ride a bicycle, but I have 3 mobility scooters, including a boomerbeast 2 offroad, which is using ebike components and drives all 3 wheels.

[@kenvik-q5t]

It’s surprising that the experienced e-bike shop is not describing one common electrical problem, the LCD display connected to the power button pad got bad. Which problem can be nailed down by simply plugging the battery and see whether they can be charged regardless of the e- bike not powering up. If the battery is charging then the faulty is the display which can be easy replaced and the new kit of display cabled to the power switch on/off will be connected instead.

[@fazonio]

Thank you very much for this video. The prongs weren't lining up right on mine. I went to a bike shop and they told me I needed a new battery and tried to charge me $580 for it. I cussed them out and "threw franks" all over the place. I seen this video and came up with an idea, I put some aluminum that I got off a take out food plate and surrounded the prongs with it to complete the charge. Now the bike works like new, and I got it off of Facebook marketplace for $150 because the original owner didn't know how to diagnose the problem lol. Now I got a great ebike for $150. I feel like going back to the bike shop, showing them how I fixed it without purchasing a new battery, and cuss them out some more, but I will leave it alone and be happy that I got a bike that was dirt cheap to work.

[@ArthurCeballos]

Sam's a nice guy. Visited him in person from watching your videos.

[@Maxpsterling1]

thank you. You helped fix my problem. o9ne of the inhibitors on my handle bar was making it so the engine would start. ran down the wire found it discounted it and I am good to go. still wish I knew why it didn't work. e-bike shops around where I live are pretty far away but I will have to get to one to find out why It doesn't work some day. going to go have fun with my new bike thanks once again.

[@cycle-re-cycle7798]

Helpful video. In out community bicycle shop in Benton Harbor, Mi we have little experience with e-bikes and are trying to learn more. Several of our volunteers ride them and even they are learning. One safety thing - we do not allow anyone to wear flip flops or open toe shoes in our shop. just not safe!

[@enockagyemang592]

Thanks man this has really really saved me today. If not I would have pay for motel

[@MJ0781]

This answered my question, I ordered an ebike kit and the brake sensor has levers I can’t use because my Shimano brakes are intergraded into the shifters. Also the PAS needs to be installed by taking off the pedal. I’m going to leave the PAS and the Brake Assist off. Just not connect them.

[@MrMotown2011]

I think you solved my problem. Now, I just need to test the theory. I noticed my brake light kept coming on or staying on after use. At the same time my motor which is on both wheels keeps stopping, It feels very intermittent. Does anyone know what colour the break inhibitor connection is on a modern bike or if there is a colour code? Thanks for a great video that's 9 years old!

[@Scheikima]

5:30 that part was my problem. Must have pushed the wheel a bit when cleaning my bike. Took me 5 seconds to fix it, after I saw that sensor that I remember seeing in my own bike. For some reason my brains didn't even register that wheel of magnets there, before seeing this. Thanks so much!

[@lincolnkarim1]

A simple error by a bike shop which turned out to be a disaster for me: Cyrusher XF-900 Rear Hub Motor; they placed the 'tab washer' on the wrong side of the dropout (disc brake rotor side) and the rear wheel eventually came off when I attempted to move. If this happened when I was already moving the outcome could have been disastrous. Both tab washers need to be on the inside of the dropout with the tabs both pointing away from the bike.

[@pollyg562]

my pedal assist stopped working i live in a very poor area of a very rich country and none of the 5 bike shops within riding distance will work on e-bikes, I was certain the magnets sensor was the problem I noticed it can freewheel but still it must go past the sensor , but I didn't know were the sensor is now I'm confident I can fix it or be closer to the problem, funny enough I also thought if it wasn't that its the connections you spoke about

[@mysurlytrucker7510]

[@debbiemarshall105]

I hope you check your comments for questions because I have a question about my battery prongs, it shorted out and burnt up a prong on my e bike/controller connection. You started to explain a little on that connection. My question is, where can I find a replacement connection for where my battery and controller meet?

[@sonya_lancemclaughlin8749]

[@spooxbeatz805]

I work at a pawnshop and we had a lady buy a dogleg ebike somebody left behind, she took it for a whirl and loved it. My coworkers and i tested the bike to make sure it worked properly and it did. A few days later her mom showed up returning the bike saying she was “ casual riding ” and the motor deadstopped her, she frontflipped and had to go to the hospital with face and body scratches. We accepted the return but the bike doesnt throttle even on full charge, and everything seems to be fine and properly connected but I’ll check the controller and throttle more in detail..fingers crossed

[@shekarreddy9440]

Great video. Very informative. Thanks guys. My bike is rather new and the motor makes a struggling noise and stops in assist mode. Comes back again after a minute or so. Any clues what may be wrong. Any advice will be appreciated. Thanks

[@joeonejoeone]

Initial response: Got this bike for my friend. kzbin.infoUgkxUiL0GnyDjP32RJdd660sP8mZk4CRLTCJ Delivery was fast. And the friend was surprised I would order it when she had never suggested she wanted anything but the pedal bike she had. She has now ridden the bike two times and gives it a 10 and says it is very fun. We have some hills in our town that are very challenging to climb on a typical bike. But tonight she went up with the pedal assist and loved it. I was way behind on my standard bike, huffing and puffing. Now she is no longer lagging behind me. This thing is powerful enough that a person could go around town without any pedaling. She likes to get some exercise so on flat ground she hits the red button to turn off pedal assist and only uses the twist throttle when she's in a tough spot. The bike looks good. It is really a very nice bike for the friend. Now for me, when I get an electric bike, I'm twice her size and will be looking for a bigger watt motor and battery. But this one is just wonderful for my friend. I am happy with this purchase.

Checking Break sensors can save you alot of time

[@machfiver753]

@5:16 those fancy senors being wired from the front side/bottom of the frame make perfect poathways for the ingress of moisture and dirt. To the point where it can cause the bike to fail completely or act in an erratic way switching from one setting to another and or turning the bike on and off. driving the user homicidal by the time they cut the wires to the sensor which kills any thought of having pedal assist but throttle work fine.

[@nathanbrough6489]

Heya very helpful I have a ancheer got it as a present it has developed a fault it has pedal assist it works fine in low mode but mid and high work for 2 secs then the bike turns off then you have to toggle battery off and in again and also does this on twist and go throttle

I have a Jenson pro I have a drill battery 40 volt and it's been working good..and the other day I accidentally hooked it in backwards and it sparked at the battery end and it stopped working but the control module didn't smell or looked burnt and I tried a different battery and no power still did I fry the control module and if so we're can I get a used one cas I don't have very much money my friend gave this to me for transportation for a job..Thanx

[@Chennek]

I noticed I'll try not to. I've written it in the wet a lot recently when I took apart the controller, safety box or whatever you want to call it and check my wiring. I went to the solder one of the wires that wasn't a straight connection is like the connection piece on the end of each wire. One for the battery went from the controller so I had to solder that together because the tips were so corroded I didn't think I could even clean it once I did try to clean it, it just started bending it back connectors. So much that they wouldn't fit back together very well either way. But when I tried to find a clean chunk of the wire to solder tools, I followed it on my back to the controller itself and the wire looked, chard what burned all the way 4-6 inches and I wound up having two soldiers. Basically about 2 inches from the controller unit itself could that have caused my battery to fail Or maybe the bms got tripped

[@DestinyLabMusic]

Can you leave an e bike plugged in and charging after it is charged? We had 2 Jamis e bikes with the Hyena e system and the assist kept shutting off. They replaced the controller where the battery slides in and the crank sensor and both still had problems with the assist. Also both chargers quit during the first year.Maybe since we left them plugged it all the time it was frying something (the dealer we bought them from told us it was okay to leave them plugged in all the time)

Can you give me your impression of a fault in my lombardo modeno 250. There is no battery problem. The bike starts off strong when suddenly the motor power just STOPS and the display goes dead. The STOP first occurred in POWER LEVEL THREE. A few minutes later the same would happen in POWER LEVEL TWO, Less than a minute later it would die in POWER LEVEL ONE. The entire bike was dead. I can hit the power button and it would light up and would begin to run but would stop in TEN SECONDS. I can hit the power button and it would run for about ten feet then die. I could do that all day. Does that sound like something that indicates a particular problem that can be rep
