At the request of Calnago, I will briefly introduce my Larry vs Harry Bullitt here. I got it just in time for Christmas 2017 and I estimate that I had about 4500km on it. The front tire is starting to wear thin. It is not exactly a WW-build, but considering that a normal 8-speed Bullitt with the standard honeycomb board weights around 26.5 kg, it is definitely lighter. As in the photos, with lights, bottle cages, and Garmin, it comes in at 24 kg (+/- 300g, I had to use the scale for humans for this one).
I use it for shorter trips, grocery runs, to transport my instruments, move furniture, carry all the books for my PhD for renewal to the library, and sometimes give friends a ride. I don't have kids, so it doesn't matter for me that the handlebars are where their heads would be, and I am the only user for the bicycle, so I did away with the height-adjuster for the handlebars.
The bicycle 'sleeps' in my bedroom, so I had a reference for the cleaner belt drive. An internal gear hub is important for me on a cargo bike, if you suddenly have to stop in traffic and have to get going uphills, you need to be able to shift while standing. Geneva is hilly, so an Alfine 11 instead of the standard 7- or 8-speed hubs. But I didn't want straight/flat handlebars, preferably bullhorn or drop bars. I ruled out drop bars, as I would have had a hard time even fitting a normal crate of beer below, but how to shift and brake then?
The only good solution was using an Alfine Di2, which is compatible with the Di2 road shifters from Shimano, and also with the Shimano Dura Ace 9180 TT-STI, which are meant for hydraulic disc brakes. But at this point, the project became so complex that I decided that I needed professional help, and found after a long search Marcel, who has a small store in Nürnberg/Germany and specializes in custom builds, also for cargo bikes.
Other notable parts in the build include the handbuilt wheels with halo rims, the lights (Supernova front and back), a lighter board for cargo (only about 1kg), Hope rotors, and a carbon seat post collar. I added plenty of reflective 3M tape on all corners (not so easy to photograph in daylight, but I tried).
The cockpit is Profile Design. The original bike had only the base bar, after a few months I added the extensions (carbon, bought used, and some parts painted) together with the Garmin mount.
The saddle is still work in progress. The original Selle Italia SLS Flow caused blood in sperm/urine when using the TT-extensions, so I am trying now a TT-specific saddle, which is better, but a little wide in the front for my taste.
Bottle cages are only on the bike if I plan trips over 100km with it.
I have a few more photos, but not much more to write. Please let me know if you have any questions on the bike!
