Santana's Independent pedaling and coasting (IPS) vs DaVinci ICS

[rlong]

I just received Santana's 2006 issue of Tandems & Tandeming and noticed on pg. 30, under optional upgrades, at the very bottom of the column, IPS-Independent pedaling & coasting $300.00. After doing a search here and at Tandem and Hobbs, I'm still not exactly sure what is being offered here, as most of the postings at T&H were pretty old.

Does anyone have knowledge of this Santana component offering? I ask because my wife and I are going out to Laguna to test ride a DaVinci soon.

Santana and several other bike / recumbent builders are still offering the Advanced Transportation Products (ATP) Independent Pedalling System (IPS). ATP was also doing business as Vision Recumbents and went out of business a couple years ago. As they liquidated their assets the patent and rights to their IPS system was purchased by J&B Importers, Inc. who continue to make the system available.

You can find a .pdf cut sheet on the original ATP/Vision system here:

Louis Du Brey has a rather extensive article on his experiences with IPS here:

Unlike daVinci's ICS which must be designed into the frame and integrated into the tandem's drive line, the IPS does its thing as a bolt-on replacement crankset which can be fitted to any tandem without frame mods or any real change to the drive line.

Personal preference: daVinci's system . . . gives more gearing choices with 4 *chainrings* and 6-tooth jumps. The smoothest front shifting system we have ever test ridden, bar none.

Thanks for the info Mark. The postings are very interesting. Have you ever seen a Santana running this setup?

I've only seen it used on a Santana with kiddie-cranks; not for an adult stoker. However, I've seen well over a dozen of them on Vision recumbents. It's pretty straight forward.

J&B offers the cranks for something like $100 last time I checked. They're not exactly a performance cransket. That was my only concern. But I like the idea.

Thanks again guys.

Sorry to be a newb but where? I was trying to find a page that actually showed the cranks for sale (some place I could actually purchase it from) but my googling of J&B Cycles, bicycles etc has been unfruitful

The items are listed here and can be found by searching brand for 'IPS' at J&B's website:

J&B is a wholesaler; they do not sell to the public. You would need to ask your LBS or a builder who offers the IPS system (Barcroft, Rans, etc...) to make the inquiry with regard to price, etc... in comparison to Santana's pricing.

Thanks,

Yes I found that. I guess I was hoping their was a list of retailers, or some online retailers that I could browse the components and get an idea of pricing etc

Thanks for your help.

Based on the information in this forum, I just had Greggs Greenlake (Aurora Store) in Seattle installed an IPS on an older model Cannondale. The cost of the IPS was approximately $400 out the door (but of course I spent much more on new brakes, shift levers, etc).

Captain and stoker have to learn to pedal in unison or the whole bike starts to wobble like a motor that is out of balance. We learned to do this when test riding a Da Vinci down in Portland. Once the team learns to pedal in unison (which take about five minutes), the IPS benefits of comfort for both the stoker and captain easily justify the costs. Starting and stopping is a breeze. As the captain I now need only call out bumps in the road and when I change gears. Stokers need only keep their mouths shut and pedal like hell (I've yet to meet a stoker that lives up to these requirements).

This forum saved me the cost of a new Da Vinci…..thanks.

Sigh. All the fuss about different Independant Pedalling Systems like they were something new. The wife and I have had one for nearly twenty years, on our Counterpoint Mark II. She can even pick her own cadence. :eek: Oh the horror of using something beside a stock tandem. :rolleyes:

My LBS can get the stoker crank for $130 and the captains for $112. My wife and stoker is getting over a broken leg and I figure with the IPS she can rest her leg as needed.

Bikepartsusa.com has them. They are one of the last items listed under cranks.
