December 10, 2016: Gates belt coil and uncoil
I've put together a short video illustrating how to safely coil and uncoil a Gates belt. This is a useful skill for traveling with and/or storing a belt. The link to the video is:
October 2, 2016: Rohloff hub disc brake rotor removal
We recommend that, for disc brake-equipped bikes, the disc rotors be removed to pack the bike for travel. Removal of the rear rotor on a Rohloff-equipped bike, may be slightly more complicated than for an ordinary wheel, but still straightforward. See our clear and simple directions for Rohloff rotor removal and reinstallation.
September 25, 2016: Lands End to John o' Groats
A couple of days ago we returned home from riding the LEJOG (Lands End to John o' Groats, also known as End To End) ride in the UK. This had been a dream for us for some time. We rode it on a Co-Motion Primera tandem, with performance enhancement features. I will put a summary of the ride and of the tandem's performance on our Facebook page soon.
August 7, 2016: Lycra and the washing machine - an update
A couple of years ago I wrote a short piece on my progress with trying to figure out how to best launder lycra, and sport clothing in general. This is an ongoing quest, but I am pretty happy with the laudering procedure I've worked out so far, so have put up a brief update on lycra and the washing machine.
June 27, 2016: San Juan Islands Tour
Registration is closed for the San Juan Islands Tour. We can arrange a custom tour in the San Juan Islands almost anytime. Contact firstname.lastname@example.org to find out about your custom tour.

January 9, 2016: Tandem Rentals and Test Rides - A Clarification
Please see the latest news on the home page for a clarification about our test ride/rental policy. In short, we believe you should be able to do a comprehensive test ride of a tandem without paying a rental fee, and it is also our policy that if you rent from us and then decide to buy a new tandem from us, the rental fee likely will be credited toward the purchase price of the new bike. We want you to be able to determine if a bike is really for you before committing to purchase. To see the bikes we have for rent, click on our rental page.

July 15, 2015: Tandem Diversity San Juan Islands Post-Rally Tandem Tour
At the conclusion of the Bellingham Tandem Rally (see below), Tandem Diversity departed for a 5-day, 4-night tandem tour in the spectacular San Juan Islands of Washington State. This was a very small tour for 2 couples, focusing on San Juan and Lopez Islands, basking in the beauty and tranquility of this remote archipelago. The tour was so successful we will likely repeat it next summer. To see photos from the tour, take a look at our Facebook Page. To see the itinerary from the tour, check out our Tours Page. If you want us to let you know when dates and itinerary are set for next year, drop us a note on our Contact Us Page.
July 15, 2015: Northwest Tandem Rally 2015 in Bellingham
Beautiful Bellingham, Washington, home of Tandem Diversity, hosted the Northwest Tandem Rally 2015 over the July 4th Holiday. We were the title sponsor of the rally, which was put on by Mt. Baker Bicycle Club, an organizing committee, a dynamite director, and an incredible staff of volunteers. The city showed its best to the more than 800 riders who came on more than 400 bikes, from 28 states and 3 Canadian provinces. Participants stayed in area hotels (the venue was the Best Western Lakeway Inn) or in WWU dorms, or camped at Civic Field. Four days of riding complimented all kinds of activities including a dinner cruise on Bellingham Bay, brewery visits, Tour de France viewing, and fireworks viewing from the top deck of the Bellingham Parkade! Find out all about the rally from the NWTR 2015 website and from the Northwest Tandem Rally Facebook Page.

October 9, 2014: Travel Pump and Mini Pump Follow-up
We previously reviewed travel pump and mini pump entries from Lezyne and Topeak (see Feb 3, 2014 and Sep 9, 2014 news entries below). We found all four pumps tested to be of good quality and we recommended all of them. We recently completed our tandems-only tour in Western Turkey (see tours page) and can now report follow-up on hands-on experience with both of the Lezyne pumps.
Lezyne travel pump: This pump packed easily in with the tandem in one of the Co-Motion travel cases. In our review we had commented on the universal head wanting to pop off the valve stem during inflation; on this trip we just threaded the pump hose directly onto the valve stems and this worked quite well. The pump worked flawlessly and during the trip quickly became the pump travelers sought out to initially inflate their tires, and for later top offs. No problems whatever with the pump.
Lezyne mini pump: This little guy was selected to go with us because it fit into the bottom of our rack trunk. We had one on-the-road flat, so had occasion to use it just that once. It also performed flawlessly. I had not checked the number of strokes needed to inflate a 26 x 1.25 " tire prior to the trip, so on the road I guessed at 275 strokes. This actually over-inflated the tire by about 15 psi, so 250 woud have been fine. One of the things I really like about this pump is that, as you approach final inflation, it does not get more difficult to push the handle down. The pump is very smooth and consistent throughout inflation.
Final analysis: The Lezyne pumps performed flawlessly. They are light, sturdy, and well designed. Based on real use, we can confirm our original recommendations of both pumps.
The travel pump MSRP is $99.99. It can be purchased on Amazon right now for $79.92. The MSRP for the Micro Floor Drive (without gauge) is $44.99. On Amazon it now lists for $39.98.
September 9, 2014: Mini Pump Review
Mini pumps serve a very useful purpose for on-the-bike inflation devices in instances where alternatives such as CO2 inflators are not practical (international travel, for instance). We took a look at two of these. Both are great pumps. See our evaluation here.
September 9, 2014: Tandem travel and climate change:
We wanted to work out if our desire for and advocacy of tandem travel could be squared with our desire to also be good global citizens. Short answer: Yes, we think so. Long answer; Read the article we wrote summarizing our findings here.
August 22, 2014: First ride on the Cascadia Alfine:
Granted, this is a single bike, but we do singles as well as tandems, and also I am quite interested in the performance of this drivetrain, and how it compares to the Rohloff drivetrain. So, we ordered up one of these, assembled it, and I just took it for my first ride this morning. My first impressions are quite positive. In fact, this may very well be the ultimate bike of the future. Let me start off my saying that, even though Co-Motion touts this as a touring bike, there is no doubt it also is a capable recreational/club/century ride bike. The frame is a Cascadia frame, 58 cm for me. I put Panaracer Pasela Tour Guard 700 x 28c tires on, and I'm running those at 110 psi. Also, Co-Motion specs the bike with a 110 mm stem, and I dialed that back to 100 mm, partly because I wanted to accommodate my age-related neck and back issues by sitting more upright. The ride is quite comfortable.
I am a bit at a loss for words to describe the ride. It was so very nice. I can't remember ever before getting on a bike and having such a pleasant first ride. Not only is the Cascadia itself a sweet ride, but the drive train just makes it even better. It is smooth, quiet, clean, and trouble free. Shifts are delicate and without any grinding or hesitation, though it is better to let off just a teeny bit on down shifts. Of course, the hub can be shifted while stopped. Performance was flawless at all speeds and under all conditions, including aggressive climbing and sprinting.
This most certainly must be the future of bicycling, once costs can come down to a more conservative level (this bike retails for about $4795.00). Here at Tandem Diversity the belted Rohloff drivetrain has become somewhat our signature product; it is very possible the Shimano Alfine Di2 will supplant the Rohloff for us - we'll see.
Things I like about the Alfine:
It is quiet and smooth, shifting is flawless, the gear range is pretty good, and the shifter is superb. I love the brifter mounted shifter and the electronic shifting.
Things I would like to see in the Alfine:
I wouldn't change much - maybe a little lower low gear. Also quick release would be nice, for fixing flats.
What about comparison to Rohloff?
Things I like about the Rohloff:
Excellent gear range, durability, evenly spaced gears, quick release wheel super easy to remove and re-install.
Things I would like to see in the Rohloff:
Quieter operation, brifter mounted shifters, electronic shifting.
I'm also wondering if the Alfine with belts and Di2 is a tandem rated drivetrain. This is something I plan to review with Co-Motion right away - if this can be installed on a tandem, it becomes a dynamite tool, in my opinion, for the general tandem population. Not necessarily for weight weenies and testosterone laden go fast teams, but for most of us the smooth, quiet, clean, essentially maintenance and adjustment free operation will be of far more significance than minor weight issues.
We still feel the belted Rohloff hub drivetrain is the best all round on the market now, but this system will give Rohloff some very stiff competition.
Details of this machine can be found on the Co-Motion website here.
Gear ratios can be seen at that link as well.
Photos of our Cascadia Alfine, in Light Toreador Red, are here.
We will keep you posted on any progress bringing the Alfine hub, belt drive, and electronic shifting to tandems. In the meantime, let us know when you want us to build your Cascadia Alfine!
August 19, 2014: 1000 mile review of our Co-Motion Passport Tandem:
Well, ok she has 1142.8 miles on her as of this morning, to be exact. We took a bit of a flyer last year in ordering up a new Co-Motion Mocha, with Rohloff hub and fully belted drive train. Our thought was this would be an ideal travel bike: smaller wheels easier to pack; belts and enclosed hub easier to maintain and keep clean. We had some experience traveling with a belted Rohloff tandem (a Speedster AKA Equator), but had not ridden a bike with 26" wheels. So, this was a project based a bit on faith: faith in Co-Motion's quality and faith in our adaptability. Turns out Co-Motion's quality is spot on, but we needn't have worried about adapting.
We are now about a year out and about 1000 miles. I just changed the oil in the Rohloff hub for the first time yesterday. The old oil that came out was pretty dark, so I'm glad I did that. Otherwise, in terms of maintenance, I had to tighten up the rear wheel just a bit but there hasn't been anything else over the year.
Here's what she's done in that year: she's served off and on as our daily morning ride machine; she's ridden local club and century rides; she's been borrowed by friends for a tour in the San Juan Islans (that mileage not included in the above total); she's gone to the San Juans on tour with us, pulling a Bob trailer; she's flown to Hawaii and pulled the prototype Co-Motion trailer around on the Big Island. She's performed admirably in all these endeavors. I was a little concerned about the handling of the small wheels, but I have to tell you that I like the handling - with the 26 x 1.25 Panaracer Pasela tires I put on in place of the stock tires.
Some other captains have tried her out and said they don't like her handling, and some have tried her and like her. I guess it's a matter of personal choice. I like the ride and I like my position on the bike. In terms of fit and feel, she's my favorite of our bikes right now.
I also like the lower center of gravity; mounting and dismounting is a breeze and I can put a whole foot down at stops, not just a toe. We have to be a little careful to not drag a pedal in corners, partly due to the tires I use having a fairly low profile.
She's been as easy to travel with as I thought. So I really feel it would be a good idea for Co-Motion to accept our proposal for this model to have its own name designation, and we feel the Co-Motion Passport is the right name. The name Passport tells much about the strengths of this bike, though I must point out, it's a great machine for everyday use, at least for us.
Finally, it probably is worth commenting on our sense of efficiency and speed of the bike. Specifically, do we think the belts, Rohloff, and small wheels mean the bike has a speed and efficiency penalty relative to comparable machines equipped in a more conventional way. Completely devoid of any data or science, here is our reply: yes, a little, probably noticeable, but not enough to change our overall impression of the bike. We've done lots of group and club rides now, and we hold our own just fine in groups of tandems and singles. Anytime we find ourselves drifting off the back, it's due to us, not the bike.
In summary, a year and about 1000 miles have definitely validated our initial hypothesis that this bike, the Co-Motion Passport, is an excellent all round tandem for couples who envision diverse experiences with their tandem.
Let us know when we can build one for you!!
August 12, 2014: Tandem bicycle rentals, that is good quality road tandems, not beach cruisers or beaters, are hard to find and expensive. But there are many situations in which you might find yourself needing a rental. For example, you might be wanting an extended test of a particular machine, for example a Gates belted/Rohloff hub drivetrain. Or you might want to travel and don't want to spend the money for a coupled bike until you've tried it. Or maybe you need to ride recumbent for a while due to an injury or surgery, or perhaps you would like to test out recumbent riding before you lay out the big bucks for a recumbent machine. No matter your needs, the new Tandem Diversity tandem rental program can help you. Check out details of the program here.
July 19, 2014: One of the questions we get asked most often about the Gates carbon fiber belt/Rohloff hub drive train is about the gear ratios and range. People are curious to know if the system offers an adequate range and sufficient low and high gears. Briefly, yes, the gear selection is good and considering our aging bodies, for us is better than the gear selection on most of our derailleur equipped bikes - the Rohloff gear range is shifted to slightly lower gears, giving us good low climbing gears, but still offers for us plenty of high gears for knee mashing on flats and for descending. But, judge for yourself. Take a look at charts of gears here.
July 9, 2014: There is really big news about Tandem Diversity and the NW Tandem Rally 2015 in Bellingham - we are the title sponsor! Read all about that here.

June 2, 2014: Look for Tandem Diversity at the Northwest Tandem Rally in Pendleton, Oregon over the July 4th Holiday. We will be there as riders, but also will be spending time at the vendor displays. Our friend Charlie Buchalter, owner of Atoc and Draftmaster racks, will not be able to attend the rally and he has asked us to staff his display at the vendor fair. We're honored and pleased to do so. Not sure yet what the display will look like; we probably will have Atoc and Draftmaster racks on display on our van, in addition to whatever Charlie has for an indoor display. Anyway, we hope you have plans to attend the rally, and we hope you will stop by the Atoc/Draftmaster display to have a chat with Tandem Diversity!
May 19, 2014: Brand new 2014 Co-Motion tandems are now in stock and ready for test riding/immediate delivery. Check them out here.
April 5, 2014: Our bike order from Co-Motion is set to arrive in May. Watch this News page for information on the new arrivals. Also, tour offerings for 2015 are beginning to take shape, although only in the formative stages just now. We are in talks with the organizers of Tour TK, who have opened up a new area of touring focus - Colombia. Initial reports are of challenging yet beautiful rides with stunning scenery, and friendly, welcoming people. Again, watch this News page for updates. Also, the owners of Bike & Barge Holland have agreed to work with us to make one of their Spring tours in 2015 a tandems-only trip. This would begin and end in Amsterdam, starting in early April, 2015, date to be determined. We need to have at least 14 couples commit by early May, 2014 (about a month away) to make this trip viable. We encourage you to contact us soon to put your names in for this trip, that promises to be memorable. To learn more about these experiences, check here, or let us know of your interest by contacting us here.
March 3, 2014: We are continuing as a dealer for Co-Motion Cycles in 2014. Our 2014 bike order will go in soon.

Look for more details soon. In the meantime, check out the Co-Motion Cycles website here.
March 3, 2014: I've posted a listing of the tandems we've owned over the years, including those that remain in our current fleet.

February 3, 2014: Our travel floor pump gave up after a long and productive life. In searching for a replacement, we compared two travel floor pumps. A review and comparison of those two pumps is here.
February 2, 2014: We at Tandem Diversity have been fans of professional bicycle racing for many years and have had the very good fortune to experience and share very intimate, inside looks at the sport over the years. I've summarized our years spent as racing fans, including close looks on the inside, in an article written to reflect on what the most recent revelations about drug use in the sport mean to us. Read it here.
