Description
This is a bicycle mount for the generator described in thing:28762.
Instructions
You can get the OpenSCAD source from my GitHub account: github.com/haydnv ; it's in mark1/mounts/bicycle. This is designed for a specific bicycle, so you'll probably need to tweak some settings to get it to fit yours. Make sure the gear on the rotor cap matches the gear on your bicycle's back wheel.
You'll need:
1 bicycle with the rear wheel removed (make sure to keep the axle handy). If the kickstand doesn't look sturdy enough to support a person without a rear wheel, get a sturdier replacement from a bike shop.
1 electrical generator, thing:28762
1 tube of gasket sealant
Print 1 mount, 1 mount_support_a, 1 mount_support_b, 1 rotor_cap, and 3 pins
Glue the rotor cap to the generator with gasket sealant and allow 2-3 hours to cure
Put together the mount and supports such that they fit snugly with the bicycle frame and the top hole is 12cm above the rear axle of the bicycle.
With the bicycle on its side, secure the generator to the mount with the pins and re-insert the bicycle axle. Secure with nuts/bolts as appropriate to your bicycle

Why remove the wheel rather than spinning a smaller wheel or drum against it? This method would give you better RPM on the generator (the bicycle wheel and drum are essentially a very large gear and much smaller pinion) and it wouldn't require disassembling the bike.
I did it with a drum and immediatly dismantled it because the sound and vibration generated by the bicycle tire is just too bothering (unless you live alone).
That's not a bad idea, but I wanted to keep as much as possible printable and I couldn't think of a good way to 3D-print a drum assembly. Suggestions welcome!
