Mikrokopter test flight
Had the Mikrokopter I built recently back for a few tweaks, and took the opportunity to play with it a bit 😉
Rohloff S&S Bike

Started off with a Surly Long Haul Trucker frame, chopped it to fit the S&S couplings, replaced the rear dropouts with sliding Rohloff-compatible ones, then built it up like this…
Rohloff QR cable stop

Problem: On an S&S equipped bike, how do you separate the Rohloff cables neatly?
Solution: Make a custom quick release cable stop which unclips at the push of a button.
So you just undo the two bayonet cable splitters at the back hub, unclip this, and the cable can uncoil and stay attached to the front half of the bike…
Rohloff stem mount shifter for drop bars

A little bit of machining required, but I think this is the best way to fit a Rohloff shifter to something with drop bars – looks tidy, and you can operate it peppergrinder-style with either hand…

Fuel Cell Bike
Fuel Cell Bike 2, originally uploaded by Ben Cooper.
Found some old pictures of a bike I helped build for the artist Simon Starling – called Tabernas Desert Run, this fuel-cell-powered bike was ridden through the Spanish desert. It’s now in GoMA – Glasgow’s Gallery of Modern Art.
It’s got a 2kW Ballard fuel cell, running from two aluminium hydrogen tanks which would be fitted to the seatstays. The fuel cell was used to keep a NiMH battery pack charged, and the battery pack ran a 900W Heinzmann motor through a custom control system.
It’s meant to look bodged, by the way 🙂

Sliding dropouts so there’s no need for a chain tensioner…
