Are we on the same bike ?
You should be able to hand taught that nut initially and then tighten it with a tool !!
Have you fitted the washers behind the chainring first ? The nut should be direct against the outside of chainring.

Any pics ?

Sounds like an issue with your compression ring mate, have you got it the right way ?
Did you replace both the upper and lower cups for the bearings to fit correctly?
Make sure your bearings are the right way as they have a slight chamfer for correct fit and also use the crown race provided as I'm sure I had that issue until I swapped the crown race !

Hope that helps

Awesome, it's a good feeling sorting stuff out isn't it saves loads in the long run not having to keep going back to a bike shop.

Rear mech and motor are the only surviving OEM parts on my bike now and after today's ride I'm on 2991 miles.


I don't want to sound patronising ( just offering my advice that I learnt the hard way lol ) take it for a test but not too excessive and then loosen that stem and tighten that top cap slightly as it will most likely have a slight bit of play in it after the first ride. You'll then be reet to go. Oh..... Make sure you redo the stem lol.

Yea mate sounds expensive buying all the tools at first but not bad something breaks buy tool for it plus the part,advice taken thank you

Just went to clean chain and noticed the chainring was wobbling looks like a problem with the offset did you use another spacer when you fitted yours ?

Ah.... I thought I just had a problem with that. Yes I had to purchase a shim washer ( 30mm ID x 42mm OD x 1mm thickness.

I bought a bag of 10 but you will only need 1 and place it inner the chainring and spacer.

So you will have working inwards...
Lock nut
Chainring
Spacer
1mm Shim washer*
Inner spacer

*If you want I can send you a couple over ( 1st class ) for free ? Obviously private message your address if you decide you want me to send you some but should be easy to source if not

There's usually one inside the spindle going into the motor kind of, you might need to pry it out if ever needed but if you've not noticed it then don't worry. I regrease it all etc regularly so that's how I know lol.

Click on my profile and message, I will send you a message too.

Shim washer

I will send you a few so you have spares

 

[Rhys99]

Spacers arrived thanks again mate,however when i put them in order u stated as in the shim washer at back i found it was rubbing on motor and making chainring stiff to pedal but put it infront of the stock spacer not internal one and it runs smooth did u not have that problem ?

No probs mate, glad you sorted it I will have to have another look cos I'm sure I placed in the order I said ! But it makes sense what you're saying. I definitely don't have any rubbing etc.

Got the broken bolt out from the Defy 35.

Titanium drill bit into broken bolt,

used a thread tap thingy to catch onto the broken bolt and began to push thread it out,

this was working until the threading bit snapped lol ( only to me !! ),

Drilled into the other end of the broken bolt, now it had a good portion of drilled hole and had worked out close enough to force a hex bit into and take the bolt out.

Bit of a bodge job but it's job done
Just need to source a new bolt now

Reverse Base 790 bars

Fitted today

 

[Ian986]

I know a bit of a belated congratulations on your first jump I have not been on here for a while

Lots of mods too

 

[Slymobi]

Decided to get a bit more bite up front and upgraded to a 203mm rotor.

Purchased 2 disks ( cheapish ) to see if the left over mount( 160-180 ) from previous forks would work.... Tested and could see the caliper was a wee bit low, added a washer to each side and re-tested...

That's much better aligned and hopefully will do the job

Still needs a bit more bedding I think but the initial testing was good.

Will fit the second rotor onto my spare wheel set.

 

[Slymobi]

My lad ( 12 years old ) decided he wanted to ride again ( last time was a good few years ago and ended with a bad fall which put him off completely) and bought himself his 1st real MTB today.

View attachment 118642

Absolute bargain albeit needing a few upgrades in the near future.

Will be starting with baby steps with him but so excited that I will have him as a ride buddy.

He can out grow this and move onto my Scott aspect 29er in a few years and then my youngest ( 6 ATM ) can then have this when he's ready to be our ride buddy

The future is bright.....

Hey @Slymobi, did you manage to figure out the standard for mounting the chainring? I am pretty much in the same situation as the one in which you found yourself previously, in that i damaged the original Miranda chainring, Haibike support are completely useless, and ultimately after having purchased two chainrings, one of which is a Raceface Bosch gen 4 mount type, none of them fit... The motor on my bike is Yamaha PW-ST and the number of teeth on the mount is the same as on the Bosch gen4 standard, 28 teeth, but the ones on the Raceface chainring seem to be a bit wider than those on the original Miranda chainring.

Thanks

The kmc gen 4 which is in this thread somewhere is what works for me but another person with exactly the same motor and bike has said that the kmc one didn't fit his !
I've had 3 of the kmc chainrings now so they definitely fit mine lol.
