I had similar problems with a bbs02 hard tail.

I settled on a 36hole hub with Big Ben tyre and all seems well. I also use a rim designed for calliper brakes, as I think these may be a bit stiffer.

14g spokes are optimum as well. I noticed recently that (fatter) 13g nipples (in certain rims) force a near 90 degree angle against the rim. Swapping to the slimmer 14g nipple, and the extra space available means the nipple angle can rotate more freely and ultimately point towards the hub spoke hole when tensioned. Crucially, this avoids an induced shear load on the spoke.during the wheel build

Brass is low friction, and is supposed to rotate back, but doesn't rotate back enough sometimes - this is why when tightening spokes, I overtighten slightly, then loosen by about a quarter turn afterwards, to prevent leaving a twist... whether this works as intended is unsure, but I haven't had a broken spoke on my newly self-adjusted new wheels yet (700+ miles and counting on the new wheels, light rider, light bike, bbs01b limited to 15mph, roads only)(I only ever get broken spokes after some accident anyway)

A blob of marine (thick) grease on the spoke threads helps with this. It also equalises thread friction which I’ve found helps when truing, and hopefully slows rate of corrosion between dissimilar nipple/ spoke materials.

That's an interesting idea, but does that sort of grease dissolve rubber (inner tubes)? It's why I've avoided applying grease. I'd definitely try that if my wheels were tubeless.

Only a tiny blob used in the spoke thread, and the grease tends to get pushed out away from the tube when winding in the spoke. Rim tape acts as a barrier. I’ve never seen inner tube dissolving problems.

That's one good reason (for me) to not use cotton rim tape.

If you can reduce the dish/offset a little, it makes the wheel stronger.
This involves using washers/re-spacing axle to move the wheel over more towards the drive side and then re dishing the wheel back with a spoke key. It can be tricky and easier to do with v brakes. The less gears, the better. Generally speaking, the more symmetrical the wheel the stronger.

I might buy one of these (yet more gear to purchase - it never ends lol):

How fast do you travel on your Bafang HD? If yours is unrestricted and you're a heavy guy on a heavy bike, regularly hitting potholes on the flat at 30mph+ , you're going to break spokes!

Or is your "Start current" too high, applying too much torque on the rear wheel from a standing start? That can be adjusted using the Bafang config tool.


26" 48 hole rims on ebay:


40 hole:


Looks like you're going to have to do a fair bit of Googling, to find your components for a build.

Is this suitable for your bike? SJS are a bit slow to dispatch, but anything I've ordered has been delivered within a week - 48h 26" £134.99 Inc VAT :



Can you fit fatter tyres on the rims you have, to absorb shocks?

Its as it came from the factory .

I was looking at this .


Would a more modern bike with bigger wheels be more suitable ?

Even if you buy that wheel, chances are it'll need truing a little bit anyway - every wheel I've ever bought, has needed truing... but I tend to buy as cheap as possible. If it were me, I'd try all the cheaper adjustment, wheel and tyre options first - but I'm a cheapskate.

No reason not to still use the bike as a truing stand today flecc.
Indeed, I built the heavily offset 20" motor wheel below in the widened rear frame of the bike in the photo below that, with it upside down of course. And I was sitting on the edge of my bed in my ground floor bedroom!

Alfine 8 yes very good as long as it is set up correctly, I had my one on a mtb using double rings up front I well below the recommended 2:1 recommended gearing for it using a 32t small ring.

I'm going to buy rims, catridges and spokes to make wheels myself next time, because the two new wheels I bought recently were both ever so slightly wonky, and they got wonkier over time, which forced me to learn to tue them. If I'm going to have to true brand new wheels, I may as well assemble them myself in the first place!
I'd recommend this book for wheelbuilding, I always refer back to it when I've got a wheel build coming up.

A voodoo hoodoo has come up locally for £150 in a large frame size,which would give me more room as my bike is a medium ,i may go for that as its a more modern bike .Which gives me more options for forks in the future .Is the Voodoo ok ?
