I note the company's website states this is a single speed bike. There are two separate chainlines, each running three cranks. The rear wheels have drum brakes in the hub, and the chain ends up on the outside of the wheels. This would preclude any form of internally geared hub. So your option would be to build a horizontal donkey shaft that terminates ...

Answer Yes its a standard cup and cone axle. I had to unbolt the reaction arm from the chainstay, and unbolt the brake cable from the activation lever arm. This was simple. Gotchas though - you have to remove the drum brake completely, and the inside cone is recessed so its hard to get a cone spanner on it. Best method is to get the inner cone and lock ...

Any cranks should do, as long as you can attach two chain rings to the rear spider. My guess is that chainline is unlikely to be an issue if it differs by up to 30mm, as it's a longer run than on, say, a dérailleur system which seems to cope fine with offsets of at least 30mm. What you will need to watch is that the two chains are narrow enough that they ...

You can use whatever cranksets you like and have available. But tandems need either an eccentric bottom bracket on the front, OR a chain tensioner in order to set the tension on the link/timimg chain. 1.1. If you are only pootling around on the flat then perhaps the loss of the front chainring is acceptable. But any hills or a good stiff headwind and ...

It's definitely possible to do #1, although you need to match the bolt pattern and bolt circle diameter (BCD). That's a common change for many cyclists. If you're running both chains on the right hand side standard cranksets are all you need (this is typically why people do that) Chainline is important, and typically you would put both idler chainrings on ...

Aww man I'm jealous - can you please add a side-photo of the whole bike? 70's tandems were renouned for being quite short, and most of the length is lost in the stoker's area. Mine's a 80's model and one of the touted features is "2 inches more stoker room!" So if you want the full 70's look, embrace the aero advantage of being so close. And don't ...
