March 29, 20242 yr I have a 5 year old carrera vengeance ebike and its now un ridable due to more spokes breaking and coming loose ? the man in the local bike shop said he cant do spokes ?? and doesnt know which ones to buy for it ?? so I will need to take it to a wheel specialist and have it re built ?? seriously ? re built due to maybe 5-6 spokes ??

When the third spoke breaks in any wheel, it shows some problem is present, so you need to get the wheel rebuilt. You can take the broken spoke out and measure it to get the length, then buy a set from Ryan. You should buy 14g spokes as replacements, even if your present ones are 13g. 14g give a better ride and fewer problems. https://www.spokesfromryan.com/ Wheelbuilding is not too difficult if you follow Sheldon Brown's guide. https://www.sheldonbrown.com/wheelbuild.html Use a 4-sided spoke key, not one with a U-shaped slot.

You don't need a wheel specialist, just a bike shop worthy of the name. Clearly your local one is incompetent, so go to the next one until you find someone who is competent. Or do it yourself, that isn't impossible since I've seen many in here learn how and succeed from online advice. N.B. Post crossed with Saneagle's. .

March 29, 20242 yr To get the correct length spoke simpy remove a good spoke and measure it. Sapim Strong 14g SS from Ryanspokes/Ryanbuildswheels.

March 29, 20242 yr Halford's (who supply and sell the Carrera) according to their website do Wheel build/spoke replacement https://www.halfords.com/bikes/services/halfords-bike-repairs.html
March 29, 20242 yr Having re-laced a wheel myself for the first time at the end of last summer its a doddle,, the hardest part for me was to source the right size spokes,. and while not the best solution amazon prime saved the day allowing me to buy and return only to replace with 1mm longer etc.. with a rapid turn around to measure a spoke removed for sizeing,(if you have one available), find a ruler which measures from the end and hook a spoke over that end of the ruler, and read off the length, subtracting 1mm for stretching. If using a multi spoke spanner with lots of sizes, tape off all the sizes you dont want to use, it will save hours.... an old spoke makes a good tool for threading end caps into wheel recesses. be mindful anazon spoke sets at least, come with exactly 36x spokes and caps.. dont loose any.. And when it comes to beating up your just trued wheel for the first time wheel, dont hold back One or two youtube vids on the subject and you will be well prepared,
March 29, 20242 yr Checkout my post here, this guy will rebuild your wheel with a stronger rim and 14g spokes if you can't find anyone local to you https://www.pedelecs.co.uk/forum/threads/crossfire-rear-rim.43600/post-654638

I'd certainly pay £113 for a trued handbuilt 20" wheel, if he does 20" with wide rims, I'll ask.
March 29, 20242 yr Poor man's guide to wheelbuilding: Take them out and replace with new one at a time! Then you always have a fairly true wheel with less stress on the wheel builder. But I agree, it is not as hard as you think.
March 29, 20242 yr If you want to build a wheel you're first going to need to buy a spoke machine. This Phil Wood is ideal. A snip at a smidgen under £6k ........ Very simple to use. You select the length of spoke you need on the measuring gauge, set that.Decide which thread you want and put in the die. Then place on a new uncut and full length spoke and turn the handle. The machine cuts the spoke to the exact length and rolls the correct thread on it. It doesnt cut the thread, it cold forges it so no metal is lost, which would weaken it. If you go to a specialist wheel builder, or someone who calls himself such and doesnt own this machine, he's an amateur.

April 3, 20242 yr Author Halfords looked at the wheel found about 4 broken or missing plus a few loose and said around £170 to rebuild the wheel??? so I am going to buy the spokes from the man whom I was given his details and get a man from the bike shop near me to try and put them in and see what happens otherwise what to do ?? I cant afford £170

I cant afford £170 The wheel needs a complete rebuild with 14g good spokes , if spokes are routinely snapping and there are already missing spokes then the original build is sub standard.

I cant afford £170 For £170 i would certainly have a go myself even if well outside my comfort zone.. When replacing spokes 1 at a time the worst calamity would be loosing a spoke nut in the wheel recess and that just takes a bit of shaking to resolve (as long as you keep track of the nut as it escapes..) but again if only replacing a few the odd loss is no big deal.

I cant afford £170 Don't worry, you can do this. Take your time, don't rush, do one spoke at a time to gain confidence. I was forced to have a go back in October when I broke three spokes in my rear wheel 400 miles from home. You will likely need to remove disc and cassette / freewheel, and you will need to replace or patch the rim tape. I have used duct tape for patching, it works pretty well because of the reinforcing mesh. The moment you have replaced one spoke successfully, you are in control, and at about £1-2 per spoke, well under £170.
April 3, 20242 yr You can't do one spoke at a time without bending the spokes all over the place. There's a sequence you have to assemble them, which is explained in the Sheldon Brown guide linked above. I'd take all the spokes out then start from the beginning. Before you start or buy the spokes, it would be a good idea to check whether the present spoke lacing is conventional with each spoke through one side of the hub on alternate sides. With some hub-motors, the wheel is built assymetrically with all spokes on the same side of the hub fd through from the same side. Finally, the wheel could be built with an off-set. What all that means is that there could be different length spokes on each side of the hub, so you should check the length of one from each side.
April 3, 20242 yr Maybe not in a 20 inch wheel, or with a very large diameter motor. I found in my 700c non-hub motor wheel there was no issue. Any gentle bending needed to persuade a spoke into position is pulled out when the spoke is tensioned. A full build is daunting. One spoke is not!

Yeah I thought that a bike shop that can't fix a wheel is probably one to avoid.

OP's bike has 2-cross. When you feed a spoke through from the outside, the spokes on the other side prevent it from being turned up to the rim. How did your around that?

April 3, 20242 yr What spoke pattern did you use? OP's bike has 2-cross. When you feed a spoke through from the outside, the spokes on the other side prevent it from being turned up to the rim. How did your around that? If the first cross is the one just a centimetre or so from the hub flange, then mine too is a two cross pattern. I just guide the spoke as soon as it is through the rim into the most suitable gap in the opposite side's spokes, and work it gently into place. I have in this way managed spokes that pass through the flange in both 'in to out' and 'out to in' directions. It takes care to protect the rim from the spoke end to prevent scratches, and there is a fair amount of temporary unstraightness, but I had no trouble. There was far more trouble getting the centerlock disc and cassette off without the proper tools! Obviously my 700c on a normal hub rather than a hub motor has longer spokes and will be a bit easier, but my 26 inch old MTB wheels probably have same spoke length as a 700c hub motor wheel, and they look feasible to me. But maybe the pattern is not as I think it is.
April 3, 20242 yr Sometimes you can keep a wheel going by a quick replacement of the broken spokes only. I have often got a pliers and bent 13g spokes into a tight circle to get around the disk. On my bike, the 32T freewheel cog was smaller than the motor hub. All my spoke breakages were at the j bend. To replace the broken spoke, I just turned the bike upside down, put a bit of tape on the nipple to prevent it from falling into the rim cavity, remove the old spoke, tread in the new spoke and dont be afraid to bend it as necessary. Do not bend close to the tread. Roughly straighten the new spoke and attach to old existing nipple (replacement spoke must be same gauge). It will have kinks but these will come out of it when you tighten up. No need to take off wheel or remove/deflate the tyre in this case. Can often be done in 15 minutes. I have also cut and make Z bend spokes, so I can always get a bike back on the road without having to order spokes or remove freewheels/cassettes. Of course I agree that a complete rebuild is a better job as once a wheel gets into the habit of breaking spokes, it tends to continue. Edited April 3, 20242 yr by Sturmey
