Amsterdam A-Biker

[Artefex]

Welcome all,
Another delayed response...have been on holiday.
I think the easiest way to change the right and left brakes would be to switch the whole brake lever. Just remove the grips, slide off the brake lever and switch to the other side.
Or you could change just the cables but I think this would be difficult. They are hard to reach inside the tubes and are joined in some places with connector blocks. At least the front one was, made it quite hard to remove.
Post some info on how you did it if you are succesful! (We need to keep this forum alive somehow).

Hi!

finally I did it right this:

Just remove the grips, slide off the brake lever and switch to the other side.

Easy and work fine.

Thanks!

Hi to all A-Bikers,

Thanks for sharing all your experience. I finally got my A-Bike/8 (with 8 x 1.24 inch pneumatic wheels). It is a wonderful piece of engineering invention. However, it lacks minor details that can make the bike more fun to ride. Already, like you guys, I have plan to make improvement.

The first item was the seat. Incidentally, the mod I did was quite similar to Artefex's mod. The pics show the mod on the seat.



Bought a alu seat post and seat that came with seat post clamp and a quick release. The seat clamp was fixed tight to the post with 2 pieces of rivets to prevent any movement or seat falling off in un-clamp mode. Machined a new shaft for the quick release to fit the swivel mechanism. The result was very satisfying and the seat can now fold and unfold neatly.

Also fitted a tail just beneath the seat.



Folded position


The front and rear post are rather weak. I can hear snapping noise once in a while during ride. At this moment, I'm machining bush for the front post to make it more firm. If the result does improve the ride and eliminate the noise, I will post it.

Best wishes for the new year.

Nice saddle, what make is it?

Thanks. It's not a branded one. Just cost $17.

Hi 190E.sg, where did you order your A-bike? Is it the real thing?

[Amuro Lee]

I can tell you that it is not a genuine A-bike.

Folding Seat Using Standard Parts.

To make the seat fold it should be the kind that attaches with two rails, using a saddle clamp that allows adjustment off the seat angle. A quick-release bolt replaces the bolt in the clamp so that the seat can be easily folded.
The only non-standard part is a bolt through the clamp so that it doesnt fall off the seat post while folding.

I am noob, I dont get quite well, how you installed two rails. Any photos of underneath the seat? So that easy to understand.

[Artefex]

Hello,

By 'two rails' I just mean the seat clamp attaches to two tubes under the seat, like the one in the photos above. Most seats are like this and the most important thing is that it can fold down enough (about 90 degrees). Some other seats, such as BMX seats (Which I personally think are the best, especially for small light bikes) have 'pivotal' mounts that wouldnt fold all the way down and the seat would stick out.
