Jack Taylor father/son tandem
 

I spied this one over on the Paceline forum and it has become my new grail, especially as Icepick Jr. is coming up on three this year.

So many great details in the wonky drivetrain -- the chainring set with no crankarms, the miniature TA cranks for the stoker with clamp-on (!) pedal spindles, the 3 chains necessary to operate the drivetrain. It's a hoot. I love that classic Jack Taylor pinstriping, too.

That thing is ridiculously cool. Start 'em young, I say!

If you want some practical info on how this kind of setup works, you may want to PM @Roger M regarding the child stoker setup he's been using on his tandem. Maybe he'll throw in some pics of his on this thread.

Neato. This appears to be a well thought out homebrew solution. Kidbacks now have the spider on the NDS and hook up to the stoker's crank.

Cranks are out of phase.

With that 80's splash wrap, curious what year it really is. And as mentioned above, would've thought the kiddy riser set-up be driven off the stoker nds. That greasy monkey motion is nutz. Dig the stoker stem.

:thumb: Cool as heck, love it, make it so!

With the captain's a little ahead... might be on purpose.

That no-crank spider has got to be either custom or a rare part. I recall seeing one that was on a Bike-E tandem recumbent that was for sale around here last year, but it was more recent Shimano I think. And what does it have for spiders on the timing chain?

snark, snark... :lol:


Never been a Jack Taylor lugless fan... always preferred lugged construction frames.

JT did wonderful paint jobs and I've always liked their deep blue flamboyant.

Nice find.

Someone used to sell shortened, re-machined cranks down to 150mm. I think that TA made 160mm cranks but I think that they made some 150's too.

verktyg :50:

Chas.

I used a slightly different arrangement when our daughter was young. Similar clamp-on bottom bracket and diagonal chain going to the captain's crank, but I put that chain on the NDS. I then ran a long chain all the way from the captain's crank back to the freewheel on the DS. The normal stoker's crank was removed entirely. Worked fine and eliminated any concerns about cross-chained gears given the length of the drive chain. The crank for my daughter was from a kid's bike and therefore came with short arms. And the chain ring didn't quite match the number of teeth of the cross-over ring on my crank so we were neither in-phase nor out-of-phase, but rather a constantly changing phase. Of course her crank did have the pedals on the 'wrong' side so they tended to unscrew due to precession, but a bit of loctite solved that.

i'd love to get my hands on one of those kits for my JT tandem. My son would dig it and I feel like the bike would get ridden more often.

Wow. That is awesome. Congrats & let the memories begin! :thumb: :)

It's pretty easy to make them:
1. Take one TA crankarm and saw off most of it.
2. Bolt the remnant to a bottom bracket spindle.
3. Chuck the BB spindle in a metal-turning lathe.
4. Round off what's left.
5. Polish to your heart's content.
