Seasons Speeding Tikit Porteur

I’ve finished my most recent round of hacking on my Bike Friday Tikit.

Side view with lots of visual clutter, making it hard to see the bike.

I callit the Seasons SpeedingTikit Porteur. Seasons because that is what Bike Friday calls the Tikit with an internal hub. Speeding because that is what they call it when you put on drop bars. Porteur because it has a (mini) porteur rack up front.

i9 hub, new dropouts

The new rear hub is a SRAM i-Motion 9 (or i9). The i9 conversion benefited from some brazing of the bike’s rear triangle. I switched the dropouts to the pivoting dropouts that Bike Friday makes. I also had to move the rear canti studs a bit. I made a photo essay of swapping out the dropouts. The i9 seems to work well and has a nice gear range. I had originally planned on building a custom bar-end shifter, but gave up on that project. The rear triangle will get fresh powdercoat soon.

The drop bars make the quick fold a bit wide, but remove the stem and it gets narrower than a stock tikit. I don’t need a compact quick fold very often, so this is a good compromise for me. I can ride on drop bars all day long, but flat bars hurt my hands after 20 miles or so. I really love the Tikit fold, it is very fast and all of the dirty bits on the bike get folded to the inside.

I made the mini-porteur rack a long time ago and it continues to function well. It looks really dressed up with the black powder coat.

The Tektro V-brake drop-bar levers are a lot more comfortable than the Diacompe 287-V option. They seem to work pretty well on the front, but the rear is a bit spongy from the long cable run. The levers work better if your V-brakes have shoes at the top of the slot than at the bottom.

I hacked up my favorite MKS Grip King pedals to have a quick release MKS EZ axle. This lets them pop off of the bike in an instant to make the fold smaller. Taking axles out of $60 pedals and putting them into $50 pedals is an expensive solution, I wish MKS just offered these with the quick release axle as stock.

I’m taking the bike on a train ride with me soon and looking forward to giving it a real test.
