Yose Power Hub- need a new rim!

[Wayners]

@matthewslack
I was reading the size option that said 650c.
Your correct though so well spotted, thank you...
I'll order.
Yose support emailed but couldn't help.

fwiw spoke sets i bought via amazon were £12-14 per 36x set. might not be the best racing spokes, but they worked and when i got the size wrong were easy to send back,

Not suggesting you dont attempt to size your spokes correctly first time.. but if you screw that up its not the end of the world..

Update.
Ordered a new wheel rim on the 27th February. As of today 18th match it's getting ready to cross to UK I think. Taking ages.

Another update.
On other thread my 25.4mm 1 inch steerer bearing is on it's way. That's taking ages as well.
When it all arrives I want to get it all put together with disc brakes on my old MTB.

Did you order from AliExpress? My AliExpress rims arrived in about a week. I always check if the seller intends to send using a fast method within 5 to 14 days, and I order from some other seller if time to delivery isn't clear. If order value is high, AliExpress sometimes bump up delivery to fast. Or as fast as it can be from China, which weirdly is occasionally faster than than delivering from the UK.

Update.
Wheel rim finally arrived and looks great.
That's just over 3 weeks to deliver, but how they managed to keep postage at £6 will remain a mystery.



I bought from https://www.tradeinn.com/bikeinn/en/ryde-andra-10-disc-rim/140833778/p

So hopefully I'll be able to do a straight swap with yose 250w front wheel rim.

Update.

New rim seems fine. I'm in the process of swapping which is taking time. I'll have another go tomorrow which should see it on. Unfortunately I mangled a spoke nipple so will need to find a replacement.

Get some tape and block off all the unused castellations on your spoke tool ( top of pic) , It will save you LOTS of frustration..

I see your spoke by spoke replacement strategy, but suggest instead you strip the one rim and lace the new one in two steps instead, fwiw i used 3x plant pots, 1x to support the hub and the other two to balance the rim at the same height, = zero cable anxiety.

its a simple every other hole pattern for the first side of the hub (for spokes in the rim and spoke direction through the hub holes) and filling in the gaps for the 2nd, but do expect at least one false start.
But any errors are simply practice runs, and when you make as many as i did (wrong size spokes too) it takes no time at all to become pretty quick at it Tho its a bummer to come to the end and find the empty hole your expecting to fill already full and you glance circa 180 degrees around the rim to spot the 2 empty holes together or 2x spokes together!!

some web tutorials suggest using decorators easy peel tape to block off every other rim hole - wish i had..

I ordered a new park tool spoke key from Amazon that's just arrived and it don't fit. Fits my other bike wheel though.
Guess I'll have another go buying a key. I think it's 3.7mm.
I need to study how up on spoke nipples and look at options for buying. I just need one

 

[Wayners]

Hi all.
Am I right in thinking I'll never buy a matching spoke nipple?
14.2mm long. 2.5mm thread for a 5mm rim hole. Maybe the best way is to buy a new spoke and probably cheaper.
Annoying as I just need one.
Also...how do spokes come out? It's detached but I cant get it out at the centre hub. Can't find anything on YouTube so will have another look tomorrow.

 

[thelarkbox]

TAKE CARE OF EVERY NIPPLE!!! All the spoke sets i have bought (too many) come with exactly 36x spokes and nipples NO spares or extra's.
Hands n knees time maybe?
If available i would expect them to be defined by the spoke gauge ?
It seems bike engineer 101 maybe NEVER LOOSE A NIPPLE/component? obviously no bike engineer has ever used a flap bottomed box for removed parts..

If a loose spoke isnt just free, keep going undoing more until the rim is free to move off the whole spoke length, and give the spoke J end a squirt of wd40- tho if at all corroded i think replacement spokes at circa £10-20 is in order.

Update.
Tbh I was losing confidence. But...
Omg! I've actually done it . I can't believe it!.
I got the rim on and dropped wheel in the stand. Gave it a spin and thought I'm in trouble here! Massive wobble right and left by about 25mm.
Where do I start?
Well I started by looking from the side and adjusting to keep rim from bobbing up and down.
Then looking from the top adjusting left and right to take out the wobble just by eye.
Then using the rim prongs to fine tune.
I've got it almost perfect now without much effort and I'm so chuffed.
I guess I need to ride it and then have another go as stress will cause some wheel settlement?
I've located some nibbles as two have rounded off a bit so will update thread if they fit.
Will fit this yose wheel on a spare bike later this year with 48v battery.

What a shame. All that effort wasted. You've put the rim on the wrong way round. Your bike will only go backwards now!

Well done, you will be wanting to do more now.
A satisfying task.

If you contact YOSE they may just give you a replacment rim and motor as a return customer.

They offered me a 700C 350W One for £90.00 may be a lot less hassle and not much more in cost if you are getting a shop to fit your old motor ?

 

[Nealh]

Nothing more rewarding then if a bike enthusiast who likes to carry out his/her own repairs , being able to lace and true a rim is a nice skill to have in one's pocket.

To most wheel building is a black art and to look at a complecated task, it isn't until one has grasped the technique and tried it that one realises how much easier it is then it looks.

 

[thelarkbox]

The build vid i followed included a stress stage, once first balanced and round stand on the spokes if light use a lever if a fatso like me but stress each n every spoke and then retest/balance..

Finally test each spoke is taught, tools exist for the job but i relied on a lil tap from a 10mm ring spanner and my ear..

 

[Wayners]

I'm going to make this wheel dish tool. Although I used 2 bean tins on table and test distance from table to the nut. Seems close enough. I guess it won't be far out using old spokes.

Hi. Using the old spokes has worked out ok for me on front wheels or where the rider in light. Rear spoke breakage can be a problem with heavy riders. Choices in rims can be limited. You left out two important bits of information that helps to select a rim. The first is do you use a disk brake or a rim brake. The second is to measure the height of the cross section of the rim. My rear yose 700 rims were around 25mm high.
If you use a disk brake and your rims are 25mm high, as i suspect, I would recommend the rim below or similar. You may be able to source from uk supplier.
When replacing the rim, just loosing all the spokes, tape the new rim to old rim with valve holes line up and change over spokes in groups of nine starting at nearest. Leave everything loose at first and finish by trueing and tightening the wheel, starting on the drive side. Cover the cable end and dont damage electric cable and connector.
The valve holes may need to be enlarged for different valve type. I recommend not using rims with eyelets as holes can be a little tight for some larger spoke nipples and this can cause the spokes to bend and fatigue/break at the nipples.

I know this was an old reply but do you still have the ERD value for the Yose 700c rim? I need to replace my daughters.

You can measure it very easily with a tape measure if you have it unbuilt from the wheel, otherwise a bit of stiff cardboard and a tape measure.

Cut a dish out of the cardboard to clear the axle, then lay it on the wheel and mark the two positions of the inside of the rim. Repeat at right angles in case your wheel isn't round. Measure the two lengths and take the average, then add 5 mm to get the ERD.

That's all a waste of time because the new rim will be different anyway. Just buy the cheapest Chinese 700C rim you can find on Ebay, Amazon or Aliexpress - about £14, normally. Buy the 14g spokes from Amazon, which are £9.99 for 36, though you get 40. That makes about £24 for the re-build. It will cost a lot more than that in money and time to get a rim That's the same ERD as your broken one, and your 13g spokes will not give you such a good build and ride as the 14g ones.

I cant recall but anyhow I use the simple method of just measuring the original rim depth and getting a similar replacement rim with the same depth where the spokes are not been replaced (usually front wheels). Where the spokes are been replaced (e.g rear wheels), I can use a different rim depth so I measure the difference between the rim depth of the original rim and the replacement rim and add or subtract this figure to the original spoke length.
For example, my original Yose 700 rim was 25mm deep and the spokes were originally 249mm long. I replaced it with a new rim of 20mm deep which was 5mm less depth so I ordered 254mm spokes which were 5mm longer to compensate. Using this method, I can order both the rim and spokes together from the same supplier and this saves me on postage.
