CarryFreedom Lollipop hitch brkt: less sticky-out

Post by SA_SA_SA »

The lollipop hitch bracket sticks out quite far (presumably to allow for excess thread on solid axles):

on a folder this might increase folded size, and with a 3 speed hub(eg Brompton), not too much excess thread/axle protrusion is present, so the pivot pin could move inwards. I presume you could just drill a new hole and cut down the bracket (according to my calcs....).
I wondered about a fold-up bracket but too complicated I suppose.

For larger bikes, why not miss longer axles by lowering the pin (rather than widening it as on current bracket) ie the bracket is narrower but deeper?

I've redesigned the hitch.
The sticky-out hitch is an ankle biter, and I've raised the subject with Nick at CF. He say's he thought about a similar design to mine but discounted it as it may turn under load.

As it happens, I've never had a problem.
This was the thread about it.

Would a longer drop & shortening the sticking out length not work? Do you need to have room to fold over the wire on the pin, and if so how much clearance does it need?

One reason, apart from general inertia, I'm still running the original hitch on my City is because the bike mounted bit is so neat.

That was my suggestion for large wheel bikes:

Bahh, I vaguely said larger when a meant larger wheeled :( :oops: .

I was also hoping for a cheaper, more DIY as opposed to commissioned approach :)

Maybe all you would need is some mild steel, a hacksaw and file, a vice and hammer, and then a drill.
Possibly could be made out of alu instead to make it easier.

The hitch doesn't support much - if any - weight, it's just a connector to pull and push.

You can combine the radicaldesign brompton hitch with the carryfreedom by replacing the formers towball with the carry freedom lollipop's cylinder post for less stickyoutness on a brompton and perhaps other bikes.
