Parts replacement on my A-bike

by **filcharp** on Wed Apr 03, 2024 7:11 pm

Hi,
Those are really old posts, but attempting in case I get lucky
I have the same issue as described above: the Upper Steering Joint Pivot Fixture of my A-bike broke. (same as picture in this thread)
I cannot find the spare part anywhere: neither local resellers, nor internet vendors.
Can some one guide me?
Any reseller in Europe, or elsewhere ready to ship the spare part?
Cheers,
Philippe

I highly suggest everyone should put that metal band called a tube clamp/ring around the rear tube.

For safety purposes, I put the clamp around both tubes near where the locking clasps are. That way, you can prevent any bad things from happening to the bike, short of the plastic breaking.

I've given you his phone number. Do you remember that?
He is just an amateur bike mechanic.
You can phone him directly or e-mail him via lck98596842@yahoo.com.hk

Should the rest of us do this as a preventative measure?
If we can find some straps that don't look to bad, it would be worth doing I think.

The Upper Steering Joint Pivot Fixture of my A-bike broke recently.

I don't think it's the problem of the A-bike itself because I'm really a seriously overweight person (115kg :oops:

) as the recommended maximum user weight of A-bike is only 85kg and my A-bike has already been tortured by me for a whole year.

I've ordered the part from the local distributor. The price is HK$57 only.

Thanks to 得把口 for helping me to replace the part again!

The broken part

My A-bike is recovered again.

The rear lower tube has been strengthened by installing a stainless steel hose clip on it this time.

Which program does one need and do they save in gif or does one need a converter program to do that?

Hi, the image looks great because the official A-bike image was great. I captured it from A-bike official online manual and altered it to simulate the incident by using photo editing software. "Animated GIF" canbe easily created by using freewares. To paste images (including GIF) here, you need to upload the image to a server (could be free photo host like Flickr) then just put the URL with Img tag you can see in the forum posting form.

In anyway, it's always good to register to this forum, so that you can post images and also send private message to other members of the forum. :wink:

As far as I reckon, the crack will appear soon or later if your use A-bike regularly, even you take good care of your bike.

over tightening quick release clamp is absolute no-no. Although this cannot be the only cause for the crack, but this surely encourages the crack.

I already reported this cracking problem in document to Mayhem, Alex. K., Sir Clive at the London Meeting July 2007. Hopefully they will come up with some solutions.
