What's The Diagnosis? | Common E-Bike Problems & How To Solve Them
Unfortunately for us, mud and technology don’t mix very well together. Most modern E-Bikes are well sealed from the elements but problems can still occur. Chris shows you some common faults, how they can be diagnosed, when you can fix them yourself, and when you should take your E-MTB to a shop.

Hi. I just got a Lectric Xp about a week ago and the back tire is locking up. I loosened my brake calipers and it will move about 2 feet freely and lock up again!
all you say is "take the bike back to the dealer".
By the looks of it my bosch battery is dead after 38 miles… hope to get it sorted
Just having my second motor replaced bosch 600 miles combined!
Emergency please help!
Just got my rear brake disc replaced and now it thinks the brakes are engaged the whole time so I cant throttle or pedal! Flashing Tool-wrench symbol!
Brand is T4B fat tire from Calgary eBikes.. mechanic in town has no clue what happened!
hey i’m using The one easy ebike…but from last day the assistant mode Isn’t working The battery is ok.. what can i do now?
My electric bike back wheel goes for one second and stops when I press throttle but not always j have to wait a second between each press and I can’t be on the bike the pedal assist doesn’t work and the back light is always on
this is so: the it crew
have you tried turning it off an on again?
Havin a strange problem with my Bianchi. The battery is fully loaded but the display shows 0% and flashing… Any suggestions? The bike is working as it should expect this annoying problem…
I’ve got a cube acid 2020 ebike with a gen 3 Bosch motor, and It’s developed this problem, when I’m out, after about 5 minutes of hard riding up a hill, when the motor has been giving constant assistance, I loose power and the purion display starts flashing with the battery icon empty ( as if no charge) yet it usually has over 70 percent battery. Then after about a minute, it just shuts down, then I have to wait a while before I can turn it on….. any thoughts?
Hi I have an ehub on a bike I made it sometimes will just power on with out me touching the throttle ,pretty dangerous as it a 3000watt motor and my brakes are not great, Any ideas what it could be
I keep getting Error 37 on my Yosemite ebike. What does that mean?
It’s my bearings in the motor. Thank goodness I work with 2 Honda Master mechanics who replace brearings on lawn mowers daily. Same concept pretty much, right?
The bearings part is incorrect as they are not covered by warranty ( kinda ), Bearings like battery’s and brake pads are classed as a consumable item and so only have a limited warranty usually 3 months, so if anything happens after that they will charge you for the diagnosis service and the new bearings and the instillation.
Have an error code (E 06) on my valk mountain bike dont know what to do have no warranty and no manuel . The bike battary indicator on the screen is on 100% and as soon as you use the throttle or pedal assist it will drown to 0-5% and the motor wont budge
My e bike the power keeps dropping out & back in, the battery is rated at 36v 8ah, the battery shows 40v on a test meter, any ideas?
Or if your back doesn’t have warranty anymore give it to your autistic brother to fix.
I have a falcon it has been nothing but trouble
Does anyone know why my e-bike shuts off when i go full throttle?
If i pull the battery out and put it back in it comes back on but will still shutdown in full throttle mode and peddle assist mode.
Is it the battery or something else?
Any answers?…
So I’ve come across a weird problem , I’ve had a new cassete and chain fit to my ebco mh7 but when I get on the bike and start riding my pedals *lock up* and make it impossible to ride ? Has anyone got any ideas what it could be?
I have an Eco Motion MIni Pro L and am experiencing an E30 code after hill climbs. Think it’s a controller issue. Any ideas? Thx!
I’ve changed my control battery’s I have a bosch system and it worked once and it’s dead again ?
Mine you can turn off and ride turn on all works top end E bike !
My bike battery reading is tuck on level 3 and keeps blinking

Hey. My bike will run for so long and cut out. It will last longer on lower settings. But on 4 or 5 out of 5, it will cut out after about 30 seconds. Does this sound familiar?
Thank you so much for this video. My speed magnet was in the wrong place. This was the result of getting a new back wheel. Simple to fix thanks to you.
When I start to peddle the motor drags not punching but having resistance
Hi has anyone had any experience with cassette slipping on Haibike sduro, it only occurs on 2 smallest cogs. Thanks.

Hello. I have the Bafang 750c full color display.. I was really excited about how easy it was to see the wattage consumption….UNTIL I TOOK IT OUT IN THE SUN. These are impossible to see in direct sunlight. Never had a problem seeing the LED display 961.
Is there a trick to seeing these full color displays in the sun. Or do i have to find shade or bring my ebike inside to see the display..?
Thats what im experiencing some of the wires have been almost cut off
What about power cut on the ride
Wooow help full you are a such life saver pro thank you very much 2:04 “ my problem was just that thing was not in the right position “
My electric bike is going slow and then fast when in low settings and the dash board speedo is going right up and down and so on how can I fix it
I bought a 2019 kenevo 2 weeks ago ( ex demo ) with 100 miles plus I have done a further 100 miles and 14,000 feet of climbing trouble free. Suddenly the battery will not turn on or charge. Do you have any idea what could be wrong? Is there a way to reset specialized battery? Any help would be greatly appreciated 🍻
just change display holder bike won’t turn on < 2016 Yamaha can anyone help?
I had NO idea that my Boach Purion display had coin cells. (My display was dead). – You saved me a trip to the bike repair shop. Much appreciated!
Great video. Hwvr, the title should be more like "What’s The Diagnosis? | Common Bosch Shimano E-Bike Problems & How To Solve Them".
I have had a 7 gear Nishiki Electric (City-bike) for two years (done 5,000 km so far). It’s been running great until now, but this week it has started shutting off power completely in the middle of a ride. I can turn power back on, but it will shut off again 5-10 minutes later. The wiring is fine, and the bike is stored indoors at night, so I am wondering if anyone knows what this issue might be? Thanks!
and here i am with a battery, throttle controller, power delivery module and a motor
none of this pedal sensor/software bullshit, if i want more power, i twist the throttle more, if i want less power, i dont twist the handle as much, very simple and very resilient
Hey man keep up the good videos. Can anyone point me in the right direction, I’ve got a mid drive motor on my bike. Everything works, I lift my back wheel up and it spins perfectly, but when I sit on the bike the motor just shudders and doesn’t have the strength to drive forward. Any ideas??? Does it sound like it’s the clutch?? Thanks
Thank you very much, my speed magnet was turned around a bit and we almost wanted to replace it with a new bike
