Hello

My bike is progressing. I'll soon finally be able to carry passengers:
https://www.dropbox.com/s/638ecv4w71o0819/IMG_20180512_212936.jpg?dl=0

I'd like to have it convenient and have a quick hanger for my heavy backpack when I go out.

I'm planning to hang it like this:

Because the seat is made of metal, I'm planning to punch few holes in it and attach a rod on it:

Any idea where I can find heavy duty eyelet? I'm planning to put 2 more holes on the seat to install a rod to hang my backpack.

I've seen this on Amazon:

Would that work? Is it strong enough?

Thanks

I used to make marquees and the material usually ripped before the eyelet broke.

If you want really strong eyelets, you will need sail makers crumbles, these are fitted with hydraulic press,

But Raboas' marquee crumbles would suit ,but maybe you still need a hydraulic press to fit.

Looking again, I realised that rivnut would actually be better as I'd screw it up afterward.

I'm hesitating between stainless steel, carbon steel and aluminium:

Stainless would be the strongest. But aluminium the lightest?

What's best?

I need to remind you that in order to carry a passenger, the passenger must have footrests. The police will stop you straight away if you don't have any.

That's very much in my plans to add them! Even without police as safety is important.

I'm still wondering where would it fit best.

I thinking either here:

I could do with a polycarbonate sheet. But there is a risk that it will prevent pedalling properly.

Or here:

On this one, it would have a double use as it could also be used to carry stuff. But I haven t figured out what set up I can use to carry the weight of a person!

I think they need to be further back to keep the passenger's feet clear of yours, like on that chrome tube.

Also, I think you need to lock your suspension to prevent the passenger getting bounced out of the seat.

Keeping the suspensions were the whole purpose of buying suspension sissy bar from the US! Cost me £100 to get it delivered.

Why would a passenger be bounced out on my bike and not on a moped with similar suspensions?

You'll see what I mean when you try it. Normally, the seat would be fixed to the rigid part of the frame, not the swinging arm. Maybe it won't be too bad. You'll have to try it. The passenger will get another problem too that you get on mopeds. When the footrests are attached to a sprung part of the frame (swinging arm), their feet go up and down with every bump, which is not very comfortable, like somebody hammering on your feet. If you look at a normal motorcycle, you'll see that the footrests are hung from a rigid part of the frame.

Yeah I'm looking forward to try! Still waiting for parts to come in!

To avoid feet being bumped up and down, maybe I shall put the foot rest here?

In the photo, it looks too close to your feet. Don't forget that your heel is a long way behind the pedal.

Just hope the natural frequency of the suspension and seat are not too close, it could build up into something nasty :)

It reminds me of when the rear damper lost its oil on my TZR125. i was riding at a steady 60 on a smooth road, but the back was doing a cyclic up and down like a roller-coaster - not what I would have expected at all.

Ahah I'll find out soon!

Would that make a difference if I ride it on my own or if there are 2 people on the seat?
