Family Tandem Still Packing it In

It's been a quick five+ years since my wife and I bought our Bike Friday Family Tandem. Our kids are grown, we are a few years older but as we get more free time, we are finding ourselves on our tandem more now than ever.

We love the way that we can pack everything up into 2 suitcases and take it on an airplane trip to a new destination. We just got back from our first multi-day bike trip and our tandem performed flawlessly for the whole 150+ mile long trip.

Our Family Tandem rode great on the unpaved Great Allegheny Passage (GAP) trail thus making it a pleasurable and memorable trip. With the varied range of gears, wide tires and very convenient Bike Friday trailer conversion for the suitcase we had a trip that will be fondly remembered for years to come.

Whether taking an airplane trip together as a couple with our Family Tandem or taking a business trip alone with my Bike Friday Pocket Expedition, I've got great peace of mind knowing that I have the best folding bike available as well as the greatest product support when needed.

problems on saturday

Bought a BF tandem 3 years ago. I learned a lot about mecchanics since. there is no after service outside USA.

I had to change chainrings 3 times, chain once, front brakes once (not pads but the whole brakes because it broke in a slope...) and I had to take my kid to the hospital once because she had her feet hurted between the chain and chainring.

We never ride more than 5 km from home, we had to do the trip back home pushing the tandem at least 5 times. I own 5 bikes and the one I use the less is the one that has the more problem and also that cost the more: BF

STP 2011 on Bike Friday Family Tandem Traveler

Dear Bike Friday - I want to say thank you in particular to Peter Berra, but to all of the crew at Bike Friday.

I had been interested in riding the STP (Seattle to Portland bike ride) on tandem for a long time, but I saw my friends struggling with racks and finding cars with enough space to take the tandems along.

My requirements were to not have to spend any money on racks and I wanted something that would allow my wife, son, and daughter to ride without having to buy extra parts to get a custom fit.

Then while searching bikeforums.net someone mentioned Bike Friday. One of my friends did the STP on a Bike Friday a few years ago. I figured now is the time to do it.

Our Bike Friday Family Tandem arrived in mid-April thanks to Peter who expedited the order. My daughter and I stayed up late that night working to put it together. It took me a while to figure things out since the video online was slightly different from the instructions that were sent with the tandem. It turns out that the printed instructions were correct.

Along the way I got help from people on the Yak and from Bike Friday support. The plan was to start training for the STP with my 13 year-old daughter. However, the maiden trip on the tandem was with my wife. We rode a nice flat 12 mile route in Skagit valley during the Tulip Festival. We then rode the tandem to a nice lunch in La Conner - we didn't have to worry about parking!

I then started training with my daughter. Our first ride was just around the neighborhood getting familiar with to how to ride. I even did a short half-block ride with my son. So everyone in our family has been on the tandem.

On one training ride we were late getting back for my daughter's friend's birthday party so we stepped on it. I put it in the smallest cog and cranked up the internal hub.

We were zooming along at around 17 mph or so. I thought I started to get pretty tired when a guy in a blue jersey rode by on a single shouting, "Thanks for the ride!" I didn't realize until he was 15 yards in front that he'd been drafting off of us.

A little later, another rider passed us and he had a big grin on his face. I felt my daughter push harder on the pedals so I pushed it up a little -- but I was getting a little tired.

Then we saw two tandems ahead of us and we caught up to them, passed them, started to run out of energy, and they passed us. Finally, one of our friends on a tandem caught up to us and we made it back to our car.

My daughter then told me the guy who grinned at us was drafting off of us too. As I drove, I asked my daughter if she had fun. She said, "Yes!" I asked her why and she said she liked passing people.

I started to learn more about my daughter as we rode -- more than I ever would have if we didn't ride tandem. Since then my daughter and I have done the SWAN Century, we've ridden up Crystal Mountain, and have gone on rides around Lake Washington and Lake Sammamish.

Our biggest ride to-date, is the Cascade Bike Club STP. We had over 40 riders in our group and we rode to support the International Justice Mission.

We rode about 200 miles over two days on the Family Tandem. We got a lot of tandem related comments like, "Your dad's not peddling hard enough" and Bike Friday comments like, "Hey! That's a Bike Friday! Where'd you get that?"

On the second day, the rear chain broke. I was able to fix it with one link short so I'll be ordering a new chain soon. I guess we had been really pushing the tandem, passing people left and right and getting passed by an equal number of other people.

But we finished the STP on the Bike Friday Family Tandem Traveler! At this point I believe we have logged over 500 miles. We are really enjoying our Family Tandem. I like the fact that I can shift while stopped and that I can easily assemble and disassemble the tandem in 15 min. or so.

I also like the wide range of rider accommodation. I would probably opt for a smaller small cog to go just a little faster. For those of you considering it -- I highly recommend it.

The single BEST purchase I have ever made!

Bike Friday's owners could go to the Hall of Fame based on the Family Tandem alone! This bike is so much MORE than an assembly of tubing and tires and components. It's a flying carpet of great magic, the perfect soltuion to the eternal quest of doing something with your kids where you can both have fun and truly communicate. My rides with my son (13 now, 8 when we bought the bike) on the Family Tandem are the BEST, absolutely the best memories he and I have. We've had a complete Blast! on this bike - physically close enough to talk and hear (and conspire) well, with the bicycling effortlessly filling any gaps in conversation. You learn little from a child by asking questions ("Tell me about school today." "It was fine."). You learn everything by being close enough to hear as their thoughts and impressions burble out during a long Family Tandem ride. So many times, it was just us in our own world, father and son on the Red Bike. The genius of the Family Tandem design comes into focus once you own it. Most significantly - the main tubes are low to the ground. Even a four year old can put their feet down at a stop. This is a huge security and comfort advantage to a small child. And as your kids grow older, guess what? You don't need a new bike every two or three years. The Family Tandem, with it's adjustable everything, just grows as they do. When I purchased our Family Tandem six years ago, I remember thinking so clearly, "I can't belive I'm spending this MUCH money on a bike." Within an hour of riding it for the first time, my perspective changed entirely. I couldn't belive I got so much bike for the small amount of money I paid. Our first test ride was supposed to be around the block. We didn't get back for two hours. "Dad, can we bicycle over to my school." "Dad, can we ride to Mason Park." "Dad, can we ride to the bird sanctuary." "Dad, can we PLEASE take the **long** way home." My little boy is no longer little, and I can hardly keep up with him as he rides his new road bike. But we'll always remember our hours and hours together on the Family Tandem. Like I said, it's the best money I've ever spent.

A very nice tandem indeed

The idea of being able to have a tandem with which one could travel appealed to me and we bought a Bike Friday Family Tandem. We'd had a Schwinn Paramount tandem for about 25 years and my wife had never really been comfortable on the back. I sent Bike Friday the dimensions of the road bike on which she felt more comfortable and they modified the rear of the tandem to fit her. I stored the old tandem from hooks on our barn's ceiling.

I still think of bikes with 20 inch wheels as "small" and as I lifted it up to it's storage spot, even I was surprised when I discovered that it's wheelbase was about 8 inches longer than the Paramount's. I never realized how short the Paramount's wheel base was or how little room there was on the back till I saw a couple on another Paramount on a ride last fall.

We received the tandem just as New England fall weather made riding uncomfortable. But we took it to NYC at Thanksgiving where we celebrated our 25th anniversary. We rode it on one of NY's monthly Critical Mass rides. Being NYC a lot of people on these rides are on folders, but the BF tandem was one of the most unusual bikes there and drew lots of attention.

Next we took it back to NYC and did their annual New Year's Eve ride which ends up in Central Park at midnight for fireworks. We did a few short rides on it as spring arrived, then we took it on our first major trip. We took it to Cuba. I also have a Bike Friday single and surprisingly the tandem is easier to pack than the single. Watching the video, made the packing easy. There's lots of room in the suitcases for a helmet and panniers. the airline had a 2 suitcase per person limit, and I thought we were going to be okay. But we were 22 kilos over the weight limit and were charged $110 Canadian (about $78 U.S.). I think this may have been because the flight was a charter, not a regularly scheduled flight.

Putting the bike back together was easy. I had to deflate both tires to get them into the suitcase and it was a little difficult with the hand pump to reach my normal pressures. And it drew lots of attention as I rolled it through the hotel. The longer wheelbase did make it more difficult, but not impossible to get into the elevator. Outside it drew the attention of the attendant of the hotel's bike rental stand and of one of the security men. I borrowed the foot pump from the bike stand and used it to get the higher pressures. The attendant seemed to be warning me that 80-90 pounds was too much. they asked how much it cost? I generally don't like to answer that question, because to a non cyclist, a decent bike seems to be prohibitively expensive, but I told him it was around $1,000. In Cuba this represents 8-9 years' income and his comment was that "He could buy a car for that much."

At home, I usually inflate my road tires to about 110 pounds. But several flats later I concluded that something closer to 65 pounds was more appropriate. The lower pressure also softened the ride. In the nearest town we had lunch in the patio of an Italian restaurant and while we ate the entire staff (host, waitress and chef) stood at the window admiring our bike.

On another day we rode 20 miles to the extremely non-touristy town of Cardenas. On the way to Cardenas, we were in a fierce headwind, but it never really slowed us down. We slowly caught up with a man riding a very utilitarian tricycle. He was thirsty and I shared my water bottle with him. As far as I could tell we were the only non-tourists in this town of 75,000. There are few cars, but lots of bicycles and horse drawn vehicles. Horse drawn wagons are the apparent mode of public transportation. We left the bike in a parking lot for bicycles, complete with attendant, as we strolled through a few shops. He asked if the bike was "muy rapido?" (Very fast?) On the way baack to our hotel, every Cuban cycling the other way greeted us with smiles and waves.

While we were waiting for the bus to take us back to the airport, a Canadian couple, that knew we had a tandem with us, kept asking "But where's the bike?" couldn't believe you could get a tandem into those two suitcases. And by the way, back at the airport a small bribe took care of the overweight charge back to Canada.

I really like the 3 speed hub. It makes it easy to grab the lowest gear. Tandems are somewhat more difficult to get going, and sometimes you find yourself at a red light in a gear that's too high. With the 3 speed hub, you can shift to a lower gear, while you're waiting for the light to change.

The only modification I've made to the bike has been to swap the cassette for one with a higher high gear and a lower low gear. Braking had been a concern of mine because the 20 inch wheels have less braking leverage than a 700c wheel. But with the V brakes, the stopping has been adequate, although I can see a disc brake in our future.

An advantage of the Bike Friday tandem is that it uses standard length cables with cable splitters...which disengage for travel. This means you don't have to carry a tandem length cable, but can use easily obtainable standard length cables...available at any bike shop. Bike Friday put on lots of braze-ons, for fenders, front and rear racks, and four water bottles. And after years of being an anti-kickstand snob, I love the kickstand.

To conclude, Bike Friday makes a very nice tandem. Plus it comes apart for travel. As I approach 60, I appreciate the step through frame design. The bike's only disadvantage is that since I'm tall it does make reaching down for the water bottle a little difficult. I appreciate that the combination of the push button shifters and the 3 speed hub means that I can push the same button for the hub or the derailleur and I will always be going up a gear or down a gear.
