Bike Friday Tikit PR
 
I love Alex Wetmore's PR rack for his Tikit:

http://alexwetmore.org/?p=576

If I had the skills I'd make one for my Tikit. I may talk to Laine at CETMA about this and get him to whip me up a rack.

If anyone is interested in such a beast for his Tikit it would be cheaper to order a few from CETMA as there is considerable effort req'd to design and setup jigs that can be utilized for all subsequent racks.

I have Cetma racks on a couple of my full size bikes and they are nice. I like what Alex did to the Tikit.

Alex does some really nice work.

If you go the CETMA route, check out the Pelican Porteur bag by Swift Industries (http://swiftindustries.wordpress.com...n-porteur-bag/)

This is quite cool.. Think he should have stopped the right side at the normal position for hanging panniers, and extended the left side by equivalent amount removed as that doesnt affect the fold or total folded package size.

There is really a lot lacking in [commercially offered] rack design these days.

edit: guess with the drop bars that rack width doesnt affect it tho!

I'd want the full rack for carrying loads on it and wouldn't use a pannier. If I wanted the absolute smallest fold on a Tikit I'd skip this rack and use the 2 sided pannier rack or no rack at all.

Very nice thanks! I'm also keen to see if I can adapt the Brompton O bag which is made by Ortlieb. If you can incorporate the Brompton QR mech than the bag should just pop on and off the rack with no buckles or straps.

I asked BF how about adding the head tube boss so I can Xfer my Brompton bags.
they declined . as a result, I'm still not on the BF bandwagon.

the head tube mounted clip with my usually stuffed Brompton Touring bag,
actually adds stability to the handling of my Brompton
and there is no deterioration of the quickness of the steering response ,
as it inevitably is when you add mass to the fork.

O bag is one of their Downtown Bags, + 2 accessory pockets,
http://www.ortlieb.de/index_white.ph...e=p-search.php
and I suppose Integrating the QR clip,
rather than making the bag slide over the standard Brompton Bag frame.
Carradice cotton canvas bags use the Brompton Bag Frame + Carradry is their waterproof offering.

costs 2X as much , about $300. as the downtown bag,
and has no more volume
than 1 front roller pannier, as i read the Specs.

Was thinking the same thing.

Just had Swift Industries make a bag for my Brompton.

Martina and Goods do killer work

fietsbob 12-09-10 06:03 PM

They use Truck tarp lining on those ? waterproof in a good shower?

I got a hold of a Mk 2 era Brompton bag support It's all Steel , Thinking if replicating it so as to make a
Porteur like rack out of it, which will clip off as easily as the bag.

There is still the limitation of height of course, given it's frame mounting,
as the bars need to be able to swing past, above the load.

maybe make it with a telescoping forward extension for Pizza Carrying?

You can't really blame Bike Friday for not wanting to "borrow" a competitor's design. Having said that even though I am a huge BF fan I am open to whatever is the best solution out there. I don't know how feasible it is for Lane at CETMA to add the Brompton bracket to his PR rack. It may not work or be cost prohibitive.....worth asking/looking into though as a bag that attaches without straps would be lovely.

fietsbob 12-10-10 11:05 AM

If all you want is a strapless bag connection, Alex used the top rail parts from the Ortlieb panniers spares.
those wrap around tubes of 8, or 10mm diameter, or larger if you leave the insert out. same- open when you pull on the strap no bounce off - hook

Here's what the Brompton front carrier block looks like http://www.foldabikes.com/PriceListH...ntCarrier.html

I've ordered a Bromptom QR bracket. We'll see what happens!

vik 12-22-10 12:44 PM

I'm going ahead with a CETMA PR rack for my Tikit that will feature the Brompton QR bracket so I can use an O Bag.

Does anyone have a decent photo of a Brompton with an O Bag on it? I tried google, but didn't find anything.

fietsbob 12-22-10 02:47 PM

Only pics I see are copied from the Brompton catalog pdf.
that one above .. #6

retailers have other priorities [I asked Todd] online sales a low one.

your post, upon completion, may be the first..

It will definitely be the first pic of a Tikit with an O-Bag.

fietsbob 12-22-10 04:16 PM

you could cruise thru http://www.flickr.com/groups/ukorigami/
& http://www.foldsoc.co.uk/
and find Brompton sub group ,
30cm overall height+ handle of bag frame,
is a requirement for P and M bar bikes ,
as the bag stays in one spot while the handlebars rotate over it, and wheel beneath it,
and so has interference with brake levers issue if much higher ..

attached to the fork so steering moves the whole rack and bag, would let you load stuff higher..

FWIW, I came across 1 picture , just Hung a regular Ortlieb Pannier
on the standard Brompton Front carrier rack and it seems to be OK.

http://www.flickr.com/photos/blank67...romptonfolders

another fellow seen a pic on line modified the alloy/nylon standard bag
support rack, narrowing the outline to match the bag.
putting a regular TiZip Shopping bag pannier on there semi Permanent,
so It comes off easily attached to the frame.. Cost is way less than O bag.

I'm headed home through Eugene ~ 18 Feb so that's when I'll get my repainted Tikit with O Bag and CETMA rack - very excited to say the least!

vik 08-16-11 09:10 AM

I'm sad to say no Tikit PR rack yet. My initial plans fell through so I need to find a new fabricator to tackle the project.

fietsbob 08-16-11 09:35 AM

My update.. someone's built to order bike was refused, didn't pass on color,
not Schwartz enough.. so I got it..
Pocket Llama, disc Schmidt/Rohloff , folding stem.
just wish the guy ordered a Kickstand mount.

I got the front pannier rack, altered the panniers a bit, 2 Ortlieb sport packers.
added 2 strips of webbing, to join them into a saddle bag unit.
[rather than 2 individual bags]
