  • Would it be possible to 'remove' the rear cranks from this bike so you could put a kid on the back with some pillion footpegs.

    Why bother? So I can cycle with a kid on the back who is too young to trust to share the pedalling. Then down the line I could reverse it.

    My thought was if you could put a normal crankset on the front, remove the rear crankset, and add one of those long tail tensioners.

    Is it just the pedal threads that are reversed on tadem cracks? Or is there any other funniness?

  • is there any other funniness?

    No, that's the extent of it.

    I think if I were trying to lose the stoker cranks, I might get a couple of beater grade drive side cranks off of aliex to maintain the existing crossover drive and saw the arms off to clear the pillion pegs. Doesn't even matter if you end up with a non-unity primary drive ratio, and you might even exploit it to adjust the overall gearing.

  • I thought about that, but then discounted it due to the nds stoker crank. But getting two of them is a good solution, and the incorrect pedal threading is irrelevant because they've been cut off!
