Jack,
Below is a picture of a complete child stoker kit that fit my (then) 3-year old. The same kit fits my 6-year old, too. This one was purchased from Precision Tandems <http://www.precisiontandems.com/catalogpartsweb.htm#childstoker>, which at the time cost nearly $600 as they were the only full kit with an amazing custom shim. And even that kit, as evidenced by the funky upside-down drop bars, didn't have a correct size shim for the stem extender to attach child-narrow cowbell bars. Now there are available full kits sold by Tandems East <http://www.tandemseast.com/parts/stoker_comfort.html> that are a little cheaper, but still do the trick. Although it seems expensive, I recommend buying a new kit as the fitting of the bottom bracket to your stoker seat tube is absolutely critical. Additionally, the link you provided to the Co-Motion kit displays a partial kit. No seat, no shims, no pedals, no handlebars, etc. If I had to pay the same price over again I'd do it because I take my two older boys on triple rides often (like even for school drop-offs) enough that they ask to go on rides all the time. Cheers, Patrick <https://lh3.googleusercontent.com/-T06XbdZ9zng/VVqQ7PsfjDI/AAAAAAAAr1o/0DoEnMWjsN4/s1600/2014-06-24%2B17.19.22.jpg> <https://lh3.googleusercontent.com/-shKn7rnHwUQ/VVqMIFSmmtI/AAAAAAAAr1c/5LUMgpxKGLM/s1600/2014-06-24%2B17.01.04.jpg> On Monday, May 18, 2015 at 10:43:16 AM UTC-4, Jack K wrote: > > Hey RBW folk, > > I'm seeking a child stoker conversion kit, hopefully compete; i.e. with > BB/clamp assembly, cranks and both chainrings (1 for child crankarm and 1 > for mounting inboard of existing ring on stoker left crankarm).
