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.

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 .

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

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.

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.

Hi. I'm having trouble with my fuell flluid-1s. Belt drive ebike. The company haven't been able to help me with the issue. I think the chain ring bolt might be lose?

And pedal it backwards there a light blockage of some kind. It pedals past the blockage but it's there. Any suggestions? Thanks. Steve

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?

Pedal assist sensor or controller likely

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.

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 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!

Thank you 👍My issue might be severed cord. It seems only the black outer covering is cut in three places. I don't know how that could have happened but that cord seems responsible for my front break. My problem is that the wheels don't move as easily as before and the pedal assist isn't as strong as it was, as well as the throttle slows to a stop. When the wheels kind of lock and are hard to turn, the assist doesn't work and sometimes it works suddenly causing it to jerk. I wonder who I can take my bike to to look at it. Are there places that take care of bikes?

Hey John, I have a question. can l replace any lcd display with throttle on my ebike? My ebikes now doesnt have throttle. i want to upgrade and put throttle on it. is there any points you can give me before doing the upgrade? last thing, changing my display will it affect my controller?

Not just any display with work. You will need to make sure it’s compatible with your controller first. If you bought it complete. Ask the manufacturer (brand) what options you have. Replacing controllers can be a headache especially if the brand is not helpful.

i received a new battery which was too big and the bike shop had to move the thing the battery plugs into and now when i switch it on the lcd will light up and go off but generally if i switch the battery off and on again it will light up and its powered up sometimes i have to do this multiple times before it powers up. Do you guys know what the problem is? Could it be the prongs arent lining up right? Any advice will be very much appreciated...

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!

i have a skylark so i don’t think i can remove the battery but everytime i try to twist the gear to go forward, it works for 1 second then stops. What do i do about that? thanks !

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.

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?

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.
