A bicycle built for two... anyone got a Morpheus?

Reply from Circe to a further question about gearing;

"Having checked like with like the gear ranges are as follows:-

1 Pino - 20.5 - 108.5 inches.
2.Pino - 1.6 - 8.7 meters

This is using a 1.5" tyre so could explain the slightly higher gears that you have quoted.

3. Morpheus Omnis 11 - 25 - 100"
4. Morpheus Omnis 11 - 2 - 8 meters

5. Morpheus Omnis Plus - 19 - 104"
6. Morpheus Omnis Plus - 1.5 - 8.3 meters

A typical triple chainset derailleur system offers around 500% as does the Morpheus Omnis Plus, however, using the hub gear systems on both the Omnis and Omnis Plus, it is easy to move the ranges up or down.

Closest to what you have/Pino gearwise is the Omnis Plus (or the Rohloff equipped Aurora) at £2549."

May have to take a trip to the UK

I'm tipping my hat in the general direction of a Rohloff equipped Morph with Shimano STX hydraulic stoppers and bigger rotors than stock. But I want it in Magenta. White bikes don't corner well.

I've always said that you were a man of taste.

Ooh, just thought. Are you in da Sham this weekend? Saturday, bandstand 1400, Andy Twyman, one man blues band.

@srw can you tell us about rohloffs and tandems and gear ranges and stuff...

No.

The Rohloff has enough low range to get us up a hill, and the top is roughly enough for most roads. Beyond that I've never bothered with the details.

Oh, and most tandems don't have independent pedalling, but you get used to that quickly.

But you see dear @srw that "No." tells me everything I need to know about gearing for a tandem.

No. The front rider can choose to pedal or not but if they want to pedal in a way that contributes to forward progress they have to pedal in sync with the rider on the back.

Oh bugger! Maybe such a drivetrain would be too complex anyway. What about a trike tandem? One person controls the left rear wheel and the other person controls power to the right rear wheel. God knows what affect this would have on handling due to uneven power to the rear wheels.
