May 8, 201213 yr Hello, I need to fix a puncture on the back wheel of my 905se. As far as I understood, it is pretty much like fixing any bike... Anything I should be aware/cautious of before I start? Thanks! Goryl
May 8, 201213 yr Is there anybody out there? Hello, I need to fix a puncture on the back wheel of my 905se. As far as I understood, it is pretty much like fixing any bike... Anything I should be aware/cautious of before I start? Thanks! Goryl For God's sake! Will someone please answer Goryl's question? I'm desperate to know the answer for when I get my first puncture. What does he mean? "... pretty much like fixing any bike ..." Help !!! I didn't know e-bikes got punctures!:o
May 8, 201213 yr I think Goryl is referring to it is like fixing any bike, but is has electrical peripherals attached..... 1- Remove energy storage and delivery system container...........battery.. 2 - Disconnect motor 3 - Remove wheel 4 - Mark the tyre opposite the valve on the side you are going to remove the tyre. 5 - Remove tyre, or just one side. 6 - Inflate tube to find offending leak. 7 - Place tube valve up against tyre where you marked it to locate offending FO and remove if present, also check inside tyre for other objects. 8 - Repair puncture to tube with propriety repair kit. 9 - Re-assemble tyre and tube and inflate. 10 - Refit to bike and reconnect electrics. 11 - Job done..
May 8, 201213 yr Try and do it without taking the wheel completely out, that way there is no need to diconnect the motor, just loosen the wheel in the cutouts and lift the axle enough to slip the tube out if replacing it. If mending it there is no need to even loosen the back wheel.
May 8, 201213 yr You can buy an inertube in a strip. It's like someone cut it and sealed both loose ends . So when you get a rear wheel puncher you don't need to remove the wheel. Just take the old tube out, cut it and insert the new tube. http://www.sjscycles.co.uk/sidewinder-sidewinder-easy-fit-endless-inner-tube-for-24-and-26-inch-wheels-prod11126/ Mart Edited May 8, 201213 yr by mart.hart

May 8, 201213 yr Author Hi, Thanks for all the answers and for the link for the inner tube. Unfortunately, I was outside trying to fix it. It took me quite a while at the end: I did not have the good spanner. There were multiple cuts on the inner tube because the puncture was due to a huge piece of glass that was stuck in the tyre so I went to buy another one. Putting it back is indeed like on a normal bike. The only thing that went wrong are due to me doing two things stupid (Honestly, on these ones I was): When taking the wheel off, I tried to pull out some wire in order to get more space. While doing this, I unplugged something in the controller (You can see inside when the bike is upside down). So when I put back everything I opened the controller to re-plug the bit (that the second stupid thing I did). Damn, I won't touch this thing ever again. I cannot fit it back. The only thing I know is that I will not put the power back on till it is properly checked... All in one, it would have been easy if I had not try to pull some wire out. Next time it is a twenty minutes job. I will catch up with work now. Hope the experience help! Goryl

That's exactly what I should have done
May 8, 201213 yr Can that possibly work ? Why aren't they commonly used ? Although very useful for a quick repair on the road, having two overlapping ends can cause chafing due to the slight movement that always occurs in the rim-tube-tyre interface as the tyre flexes on the road. That can lead to fresh failure later, so it's best to treat these double end tubes as a temporary measure only.
May 9, 201213 yr Author I am back on the road . Controller was perfectly fine. The good point of the story is that I do not have to be scared of getting a puncture in the middle of the road as I know how to fix it and it is actually fairly easy. I might get some of the double end tubes just in case. Thanks again for all the advices! Goryl
May 9, 201213 yr Hello Goryl, Well that's just great news. I could see that Davanti was very anxious for you. Also that Smudger1956 & killjoy came to the rescue with brilliant detailed instructions. I am interested to know whose approach you followed e.g:- Did you take the rear wheel fully out or not ? I would like to know these things 'cos one of these days.....it will happen to me ! Anyway, thanks for sharing your experience with us. Yours Aye, rotary.
May 9, 201213 yr Author Hi Rotary, Just one thing to remember when you read my posts: I am a newbee when it comes to bike maintenance (even the non electric ones). Here is my list for next time it happens. It is pretty much the same as Smugler1956: 1/Remove Battery 2/Cut the small plastic pieces that holds the wire that goes from the motor to the controller (No need to unplug anything). 3/Put the bike upside down and remove the wheel. You will have to keep it near the bike because it remains plug to the controller. 4/Fix the puncture (Cf Smugler1956 list) 5/Put back the wheel and put a bit of tape around the wire to make sure it stays in place till you can get the small plastic bits. My do not forget list for next time: 1/Do not pull more wire out than needed. 2/Do not open the controller if I failed to respect point 1/ 3/Make sure the wheel is properly aligned when putting it back (The ETS in London were very kind and readjust that for me). One other thing I noticed is that the slime inside the inner tube can make it a bit difficult to glue patches... I had to put a new inner tube because there were multiple cuts. Let me know if you have any questions. Goryl
May 10, 201213 yr I'm reassured ....... Hi Rotary, Just one thing to remember when you read my posts: I am a newbee when it comes to bike maintenance (even the non electric ones). Goryl This has been a really useful thread; and reassuring too. Thanks from another Newbee with similar limited knowledge Don
May 10, 201213 yr Author I am happy to take a picture so that someone can put an English word on them !
May 10, 201213 yr I am happy to take a picture so that someone can put an English word on them ! They're generally called 'Ty-Wraps' or 'Cable ties'. Available in many sizes from many places. I got some from my local Maplins store.
May 10, 201213 yr They are Tie-Wraps : http://www.workshopping.co.uk/media/cat_images_nodel/desc_4d2b18f822759.jpg ...............................
May 10, 201213 yr That information is so helpful.Thank you. The real bonus here,I think, is that a dreaded chore has been turned into light entertainment & can only benefit us all ! I often think it is easier to learn something when there is an element of humour attached. Just watch my grin when I get my first rear - tyre puncture in many years ! :o Aye that'l be right. Does a handbook come with the bike ? Because I'm just thinking all of this kind of practical information should be incorporated in some forthcoming revised owners manual. Comments welcome.
May 10, 201213 yr Does a handbook come with the bike ? Because I'm just thinking all of this kind of practical information should be incorporated in some forthcoming revised owners manual. Comments welcome. Spookily enough ... I have been in dialogue with David Miall this very day about the User Manual. Currently available on-line from the Wisper link on this site, it is due to be 'polished up' and a new version released this year. Ty-wraps are brilliant! I always snip it off when I see one in use and save it for a rainy day Don
May 10, 201213 yr I recently had to take the back wheel off on my 905SEL for the first time to change the tyre. To add to the sound advice given previously, I found that the cable coming from the motor got twisted very easily, if this happens too often the wires in the cable will break. Something to watch out for. Karl. Edited May 10, 201213 yr by karl101
May 14, 201213 yr I have just finished reading this thread with a lot of interest. Would another electrical connector near to the motor wheel be helpful? Best regards David
May 14, 201213 yr Author Hello, my completely non-technical opinion is that it would be great! It would make the bike very reassuring as a new user: If you can see an obvious and safe way to completely unplug the motor then the perspective of the first puncture is far less daunting . Goryl
May 14, 201213 yr Thanks for your input Goryl We already do this on the Alpinos, I will now implement this on all new Wispers. Best regards David
May 14, 201213 yr Out of interest how many wires are there in the cable to the motor? Can anyone recommend a good watertight connector?
