How to Change a Flat on an Electric Bike with a Hub Motor
Vložit

- 1. Make sure the system is turned off, consider removing the battery pack
2. Consider putting the bike in a stand or flip it upside down (onto the seat and bars)
3. Use scissors or other cutting tool to snip any zip ties, disconnect the motor cable
4. Shift down to the lowest gear (this makes removing the wheel easier)
5. Use a wrench (15 mm in this video) to loosen the bolts on the rear wheel, this bicycle had a 40 Nm torque rating 9~30 Torque Pounds) and torque wrenches might be useful for this
6. Once the bolts are loosened you can pull the derailleur down and out of the way
7. If the tire isn’t flat, you may need to take out excess air (this would be the case if you’re swapping tires), also take out a retaining nut if your stem is threaded like in the video
8. Massage the tire and prepare to remove it using tire levers, plastic levers won’t damage the tube, tire or rims as easily as metal tools might. Slide the lever all the way around to get one side of the tire completely free, you often do not need to remove the tire if you’re just patching a tube or replacing it. Most tires are rated 2,000 miles (3,000 kilometers) before needing replacement.
9. When reinstalling the wheel, if your bike has a hub motor be sure to index the dropout with the motor cable and alignment nut so that the motor will spin the same direction and no cables will be twisted or sheered. Sometimes the metal bump that lines up with the dropout acts as a small torque arm to provide something for the motor to push against.
10. Make sure the brakes are aligned and that the axle is completely seated before tightening things down.
11. To avoid flats you can get Kevlar lined tires and thicker tubes, there are also liners and sealent that can be added to some wheel setups to increase durability.

Great video on the rear tire removal, but this is an older video. I am looking and planning on doing the same thing someday on my 2019 Lectric XP folding bike with a 4" tire. Thanks again for what you do.
Well now I know how to deal with a flat tire that has a hub motor on it... this video is really really helpful bro. Keep it up your channel is amazing!!
Alot of good info.especially about fixing flat without removing tire and centering brakes. Thanks
Great how-to, Cort. Have a Bionx on a Tern Link D8 so this is really helpful.
Removing the rear wheel then replacing. Brilliant. I spent at least 15 mins removing the wheel & a lot of swearing. The chain on largest sprocket! simple when U know how. Many thanks guys.
Sometimes there may be something embedded in the tire itself that punctured the tube, therefore it is a good idea to mark were the valve is aligned with the tire incase you need to fully remove the tire from the wheel, that way once you find the hole in the tube, you can lay the tube on the tire lining up the valve and tire mark and find where the problem in the tire which will be in the same location as the tube patch. If you do not do this and there is something in the tire itself like a nail, a piece of broken glass, or a rock, it may damaged your new tube or repair. Careful about running your hand on the inside of the tire as you may cut your finger if there is a sharp object in it.
Didn't realize I could disconnect that cable. Thanks, I bought a new bike that's faster and better but want to replace this ones tire that keeps going flat so I can sell to a coworker
Take my zip ties, wrench, patch kit, pump, tire levers, and bike stand with me on every ride. Got it.
hahaha I was thinking just this!
Thanks for showing how to fix a flat, it good to no and it saves you
A lot of money. For the parts that are needed.very good show Bro.
He never finished the job. By the time he would have re-plugged the battery cables after carefully lining them up so as to not get them misaligned and then replaced several zip ties, trimmed them and replaced the battery and then pumped the tire back up to correct pressure... phew, you've just doubled the time this demo took. Btw, out on the trail I always find I' never remember to bring my bike stand so much easier and quicker to leave the wheel in place and just remove a section of tire rim near the puncture, pull out a piece of tube, patch it, stick it back in, reinsert the tire rim, pump up and go.
The tire patches don't always work but you know everything right...
You don’t need to completely remove the wheel to replace the tube. It just needs to be lifted enough to get the tube out and replaced. That way the cables can be left in place, although the cable ties may need to be cut and replaced.
Or use OKO 😀

Yep. You can cut the tube right?
On my stromer, if I don't have to actually change the tube, I've patched a tube without pulling the wheel off. The tire is a lot easier to get off of the rim than my wire-beaded road bike tire. If it's just a simple puncture then I just pop the bead out on one side, pull out source of the puncture, pull out the section of tube I need to repair and pop it back together when the repair is done. I hate unbolting and cutting zip ties. Not only that but the potential to lose the small spacers on the hub shaft is eliminated this way. Only problem is bike wants to fall over even with the kickstand down with this method. I have to lean it against a wall or tree or something.
Dude that's exactly what I do
Great video thanks for sharing, then the bike is back on the ground I always loosen the nuts and ad a couple of light punches to the top of the tire to ensure that wheel axle are correct in the dropouts..
Slime works great with the liners and I've never had a flat.
Good advice
Could you maybe upload the same video about a mid-drive motor? I have a mid-drive motor ebike (gazelle orange c8 hmi) with a flat back tire and I'm not sure if I'm disconnecting the wires properly. So it would be very helpful if you could give some tips about it.
13 minutes video and you missed some keys points.
Check inside of tyre for pointy things ,
Tyre can be patched without removing wheel which is much faster easier and safer requires less tools.
Slime in actually really easy to use and quite effective.
Question on the rear wheel, I have a thru-axle setup instead of a dropout (on my rear wheel frame configuration), will it be able to take in a Bionx wheel?
You should do more how to videos, they come in handy
Peter Tran Cool, thanks for the feedback Peter... I definitely plan on doing more videos like this. Some bike people are more willing to go on camera than others. Eventually I want to do a really fast thorough overview on my own but it requires a lot of setup. Since I've been traveling so much for reviews I'm just doing them on the fly for now ;) what types of things would you like to see?!
What about if you need a new tire?
Where did I read the cables to the rear tire should be removed in this manner; communication cable first, power second. Maybe that procedure only applies when the battery is connected?
Cool, I usually remove the tire while the wheel is on the bike, patch, put the tire back on. This way I don't have to remove the wheel at all.
Does that little drop out washer thing go on first, on the inside of the bike fork? Can't quite figure that out. I also have a hub cable going into my axle on my Surface 604 Colt. Any other suggestions?
I use two spoon handles, much easier to put tyres back on especially.
what size are the tyre width on that wheel ? 3 or 4 inch ? 2.6 maybe
What's the names of the e trike bikes that can never go flat like having all rubber inner tubes and at least 1000-2000 watts that can pull about 200 lbs ?
Where’s the penetration point on the tyre? Doesn’t that need to be fixed as well?
Can’t this be done without actually removing a tire rim, if you can identify where the leak is coming from you don’t have to remove the rim from the frame, especially if you’re on a bike path somewhere you don’t have access to a bike stand . Can’t you just take out the tube where the leak is and put a patch on. That’s what I used to do that when I was much younger person on a regular bike. Does the same thing apply on the electric bike style rims?
I got a 350watt ebike called Ancheer. How do i take the Axle apart so i can rewire the wires ?? What's the name of the company cause i might need a new rear wheel and the Axle cause my Axle is broke?? And the wires is in the Axle where you rewire the wires like red blue green ??
What tyres anyone know ?.
Geez, the one thing I needed to know ...getting the tire back on and dealing with the chain side. And you had the camera on the wrong side...
He didn't replace the zip ties, so I assume they're put there by the manufacturer. And once the ties are removed, there's no need to put them back?
I wish my electric bike was this easy to remove that damn back tire. for me I have to almost completely dissassemble the entire rear of the bike. all 22 nuts and bolts and they are on the inside of the frame that I can't remove so I have to squeeze my hand down into the bike and barely hold the bolt while I kill my back hunched over it trying to turn a screw 100 times. removing the kickstand, fender, butt plate, disc brake, chain, 6 axle bolts, wired secure plate, and THEN the frame bolts. Now I can slide my tire back far enough to unhook the motor wire and slide the chain off the axle to release the tire. by myself I have to take breaks or I'd die... whole process takes about 6 hours to change a flat.
Wow, that sounds extreme and like you need to go tubeless..
@@duskizm yeah I tried that too. but my bike has a 22 inch tire. they didn't make tubeless in 22 inchs. Tried to buy a 24 and cut it to make it fit, didn't work.
tyre slime isnt messy at all, used it the other day
Yep. Isn't messy at all, you hands are dirty after changing tire anyway. Slime goes with Kevlar tires like belt and suspenders.
Just use your hands to take the tire off, it's not that hard. Tire levers of any variety can damage your tire. Also, keep the tube as a spare and go tubeless, its so much better, you don't get pinch flats so you can run lower tire pressure and get more power to the ground/go offroading.
At 3:15 my wheel doesnt come out naturally. Any suggestions?
Take a piece of wood (as a buffer so you don't ruin your threads) and then tap it out! :)
❤
he says “um” choke times
Wrap those disconnected terminal ends, they look fragile! Slime, forget it, quick use maybe but before a puncture happens, nah, messy stuff hardens quick inside tube, becoming useless.
I believe in tire liners (TUFFY)
That guy sounds like Toby
So why did 5 minutes take 13?
This is to change a tube....you do not have to take of wheel to fix a flat by patching the tube....i was fixing my own flats when i was 9 or 10 years old....turn the bike upside down...first find your problem... nail or glass or thorn....mark the rim at that spot....release the tire all the way round....pull out around eight to ten inches of tube...find you puncture on the tube....patch it....put everything back....including air ....and bingo...only need to remove wheel on replacement of tire....because you can actually replace tube without totally removing wheel. Most of the vids on this subject are total overkill !!!
thats a lot of yeahs
You did not reconnect the electrical cable and put pack the zip ties. It you have a torque arm on you back wheal hub motor this also has to be loosed and bolted back, which increase the number of tools you nee to carry...
This video is not helpful for me. I have a Magnum Metro Plus which has the power cable going through the rear axle. I've found it impossible to reinstall the rear wheel after having to replace yet another broken spoke (6 in 2 months of riding). This piece of garbage is great when it actually works, but the maintenance just isn't worth it. Am I just unlucky or are ebikes just a bad idea?
Video is informative but I have to tell you, Michael and the number of "hums" in between every sentence exceeding ~100 is annoying as hell. LOL
Thanks man I'm totally aware of it now and it's annoying
He is saying “ohmm”
sorry i fell asleep can you show me again..better than sleeping pills...
You mean you don't throw them in the trash after they breakdown?
Does anyone ever answer any of the questions that are asked in these comments?? Um....No.
Ok Linus tech tips
no flat tires come in handy, one less thing to worry about..
yeah , i have bionx kit outfitted with Schwabe and tire liners but a few times over the years , hopping curbs will get a rim pinching the tube . only other option i've ever had was a bmx with solid rubber tubes
yep, solid tires are great however make sure the spokes can handle it..
sort of a Matthew Broderick voice going on here.
Umm, um,umm, umm , ummmmmmmmmmmmmm
"Torque rating" SAS
how many fking times did he say ummmh
+aviram Yeller I'm so sorry you are so crude.
I'm soo sorry your an ass!
you're not your
Fuck off man
He's saying Ohm, which is the name of the company! Slick advertising!
This guy is a dry as shroud to listen too lol
lolol this guy (ebike mec) is annoying to listen to.. is it just me?...
I don't know as I've never heard you speak.
This is too much work lol. Wow
Yeah, it can really challenging... especially with a heavy ebike. This is why I love the puncture resistant tires, and I try to keep the recommended PSI in the tires, to reduce pinch flats. Mid-drive electric bicycles tend to be much easier to service.
I don’t have a car and the nearest bike shop isn’t really within walking distance and it’s somewhat hazardous traveling on foot without any vehicle as there isn’t always sidewalks for pedestrians.
So when the bike breaks down, it does put me in a compromising position. Maybe e-bikes aren’t reliable substitutes for commuter vehicles… 😄 I can’t say I am technically confident to deconstruct all the stuff on the rear wheel to separate it from the bike
@@joshuamartin5085 maybe stop being being a little bitch and learn how to service something before using it as your main mode of transportation. Just a thought
Hey that music is very annoying i was not able to watch
He might know a lot about bikes but I couldn't watch for longer than 4 minutes because of the incessant "ahm"...
The video should be called how to change a flat tire on an electric bike for dummies.in my honest opinion if you don't know how to change a flat tire on the bike riding you probably have no business being on it
if you want God to forgive you dont commet here just go to the church and pray.
Love you.
