I just got this 'new' tandem (Link) http://www.hmi-basen.dk/blobs/orig/16885.jpg
It doesn't work because the chain isn't on, and the cog wheel on the back is not on....
There is only one cog wheel on the back.... but should there not be two?? One from the front cog wheel to the back, and then from the back cogwheel to the cog on the rear wheel??
I hope you can and will help me, so my bike is cruising around soon!!
