Everyone Wants Stability

In discussions of a bicycle's ride quality, one thing that always comes up is stability. We want a bike that is stable and we complain when it is not.Of course the problem with "stability" is that the concept is largely dependent on our skill level and cycling background. Those who are unaccustomed to riding roadbikes will often find them unstable at first, while those who ride roadbikes exclusively will often find upright bikes unstable. This does not mean that either is actually unstable, but rather that the two cyclists are used to radically different means of weight distribution. Similarly, what's "unstable" to one cyclist can be "responsive" to another. It seems that perception of stability has at least as much to do with the person riding the bicycle as it does with the bicycle itself. How useful is it, then, to tell a salesperson or a framebuilder that we want a bicycle that is stable? And how useful is that term in reviews? Clearly we need further qualification.

When I talk to new cyclists who are uncomfortable operating their bikes, instability is often cited as the problem: It can make a bicycle difficult or scary to ride, making the cyclist feel not entirely in control. In the process of teasing out what exactly is meant by this elusive concept, I've identified a number of distinct points that I would like to share, and see what others think:

Starting from a stop

Some bicycles are described as shaky when starting from a stop, as if the front wheel is wobbly and wants to turn just as the cyclist is trying to get the bike rolling forward. This is a complaint I hear a lot from women about vintage mixtes that came with dropbars, but have been converted to upright bikes and also, interestingly, about classic Dutch bikes. The feeling is sometimes referred to as "light steering" or a "light front end," and has to do with a complicated combination of the bicycle's geometry and the height of the handlebars. With some bikes, I have found that lowering the handlebars helps - in particular when it comes to the mixte conversions - but ultimately it is a matter of getting used to it. Some cyclists do get used to it, but others can't and feel inherently uncomfortable with the bike.

Cycling at slow speedsSimilar to the above, only extended to cycling at slow speeds: The bike wants to weave (i.e. feels "squirrely" or "twitchy") when the cyclist attempts to ride slowly, making it difficult to control. Aggressive roadbikes are known for this quality, but cyclists report the feeling about some upright bikes as well (albeit often they are upright bikes that are roadbike conversions). One thing I have found useful when riding bicycles like this at slow speeds, is to pedal in slow motion while feathering the brake, instead of coasting. I would be interested to know whether this works for others.

Cycling at fast speeds, downhill

When riding at fast speeds, and particularly downhill, some cyclists are alarmed to notice that the font end of their bicycle will begin to vibrate in the region of the stem and handlebars. Assuming that nothing is loose on the bike or mechanically wrong with it, this is known as "shimmy" and there are ongoing debates regarding what causes it, whether it's a problem, and whether it is even a real phenomenon. This is something that a cyclist either gets used to, learns to avoid by abstaining from high speeds on that particular bike, or deals with by getting a different bike.

TurningWhen cyclists describe a bicycle as unstable on turns, they can mean a number of things by this. One type of complaint is that the bike turns too aggressively or, "too much," overreacting to the turn. Another type of complaint is the opposite: that the bike keeps trying to straighten itself while the cyclist is still continuing the turn. Either of these qualities can make turning stressful, with the cyclist struggling to make the bicycle follow the course they would like it to follow. How to deal with this, other than developing handling skills in line with the bicycle's tendencies (or getting a different bike) I cannot say.

Rough surfaces

To some cyclists it is important how stable a bicycle feels when going over rough or uneven surfaces. While wide tires play a role, at least to some extent this seems to be also about the bicycle itself - with some bikes seemingly "unfellable" off road or over potholes, while others relatively easy to wipe out on, especially for novices. In the realm of upright city bikes, there is an increasing number of manufacturers (Pilen, Retrovelo, Urbana) infusing classic transportation bicycles with mountain bike characteristics in a way that works well in this context. Converting an old hardtail mountain bike to an upright bike can work as well. Upright roadbike conversions on the other hand, tend to be problematic in this respect - particularly for beginners.

Tire widthWhether on smooth or rough surfaces, I have noticed that tire width can have a lot to do with a novice cyclist's perception of a bicycle's stability: Narrow tires are simply more difficult to balance on across a wide range of circumstances. If the bicycle's clearances allow for wider tires, this is an easy way to improve the feeling of a bicycle's stability.

Cycling with a loadFinally, whereas a bicycle might feel perfectly stable unloaded, some notice that introducing weight in the front basket or on the rear rack can disrupt that stability. Most of the time, this happens with a front rather than rear load: the bicycle begins to weave or wobble if the front is overloaded. There can be a myriad of causes for this, and subsequently a myriad of ways to deal with them. Generally speaking, carrying weight lower on the bike (i.e. not mounting a basket on the handlebars) is said to improve stability. But some bicycles are just not intended for a front load no matter what.

While it might be difficult to express what we mean by stability, breaking it down into specifics can be helpful - both in communicating with others and in gaining more insight into our own preferences. In attempting to understand the nuances of ride quality, it continues to amaze me how the same idea can be echoed by so many people, yet mean something slightly (or even not so slightly) different to each. Does a novice who finds their bicycle unstable need a different bike, or merely wider tires? Could be either.

Into the U.P.

Crossing the Mackinac Bridge into the Upper Peninsula of Michigan.July 31, ..

The first stop was at Brimley State Park, about 15 miles west of Sault Ste. Marie, on the shores of the St. Mary's River. Several pleasant days were spent in the area. Blue skies and sunshine were abundant. Daytime temperatures in the mid-80s with lows in the 60s overnight. Very nice!



Of course I visited the Locks at Sault Ste. Marie. A very large freighter had just entered the locks from the higher Lake Superior side. It took quite a while to get it lowered so it could eventually make its way to Lake Erie and eastward. Movement was imperceptible. Only when you looked away for a few minutes then looked back at the ship could you tell it was sitting lower beneath the top of the locks. Eventually the gates of the locks opened and the ship was on its way. I overheard the Park Ranger (Sault Locks is a National Historical Park) telling someone that the ship that went through was 105 feet wide while the locks were 110 feet wide. A rather tight fit overall.





A few minutes later, a small tourist boat came through. Entering from the east side it had to be raised in order to exit on the west side and into Lake Superior.





The top of the boat is below the top of the locks.



Twelve minutes later, the little boat was on its way. It didn't take nearly as long to raise this little boat as it took to lower the large freighter.



A very nice visitor center has displays on the history of the building of the locks as well as a very informative 20-minute movie.

Autumn Afternoon, Lake Agnes

Along the Superior Hiking Trail near Lutsen, MN. This is from yesterday morning's hike, which was literally a PERFECT day! Sunny, calm and beautiful fall colors. A stark contrast to today's rainy, windy weather.

Finally A Sidewalk

When we bought this house there was a small covered concrete pad right in front of the door. For 10 years we have been wanting to add a walkway out to the edge of the garage that rans from the door along side the house. Last month we decided to do it. First we set 2x4 boards in place to hold the wet concrete in place. Thensince we hadsome large pieces of New Mexico travertine stone, also known as New Mexico marble (not as hard as true marble) wedecided to set5 pieces of it in 2 of the sections we made. The section nearest the door only got 3 pieces. First we mixed the concrete in the mixer, then poured it in, then smoothed it out, laid in the stone, and smoothed it out again. Lots of hard work. But finally it is out to the edge of the garage. We are planning to do anothersection and then go across the front of the garage. Wonder how long that will take?

Roe-Dee-Oh :: Bronc Riding

Sunday, August 21st - - After attending a community church service (very interesting mix of speakers), a pot luck dinner (good food), and driving along nearly every street in town looking for the “birthing house” where Ruth, Jim and George were born (we didn't have an address but did have a picture of the house, which was eventually located), we went to the Rodeo.



For many of the Joslin Clan, this was their first Rodeo. I had been to several but never to a “full-blown real” rodeo. It was a lot of fun but lasted much longer than any of us thought it would – more than four hours! And because it was so long and so much was going on, there will be several posts covering the activities, and probably two posts a day for the next few days – with LOTS of photos! For me, part of the fun was in trying to capture some decent images that showed the action and the excitement.

















These next four pictures are of the same horse and rider. The horse went down but the rider stayed with him... incredible ability and athleticism on the part of both the rider and the horse!











Amazing!

Assateague Island :: Sunrise

One of the things I had promised myself that I would do while at Assateague was to get up early enough to watch the sunrise over the marsh. The first three mornings had already gone by and I hadn't gotten up in time but when Friday morning (October 23rd) rolled around, I awoke before the sun was over the horizon. The clouds in the sky were bathed in streaks of orange and pink. It turned out to be a spectacular sunrise. One of the best. Ever. Mother Nature outdid herself that morning.

7:00 a. m. Walking over to the marsh boardwalk.
It was cold. And Dark.
But I just knew it would be worth the effort.
That was an understatement.

7:07 a. m. From the middle of the boardwalk.

7:13 a. m. From the far side of the boardwalk.
Looking just a little to the south of the sun.
The sky and marsh were completely bathed in wonderful light.

7:18 a. m. From a distance, using the telephoto feature.
Looking directly into the rising sun. Magnificent.

7:22 a. m. From the same spot as the previous photo.
Longer telephoto setting.
The sun rising over the horizon.

7:24 a. m. The morning has risen.
Breathtakingly beautiful. Quiet. Tranquil.
All mine, and mine alone. Until now, when I share it with you.

7:32 a. m. My only companions were the birds.
A small flock of Snowy Egrets.

Sunroom Painted

These came out kind of dark but this is the sunroom after we painted it. It is a kind of ivory color called White Shell. It was a bit of a chalange to paint with the help of four cats but we got it done. Now we have to do the celling as you can see in the upper corner of the first photo it is not finished. But first things first and we have outside chores to do first.

Firefly Bicycles: a True Story

In its two years of existence, Firefly has built over 200 bicycle frames in titanium, stainless steel and titanium-carbon - nearly every one of them documented from start to finish and shared over the internet with what seems like hoards of enthusiastic followers. This rate of productivity is particularly remarkable considering that Firefly is just 3 people: two framebuilders and a tester/designer, all of whom perform double duty as PR specialists and photographers.When I visited Firefly last week, they had just held an open house at their impressive new space in Dorchester. The recent upgrade from their prior digs will allow for even greater efficiency - helping the young company meet increasing demand and tackle their now 8-months long wait list.





To those unfamiliar with Firefly’s history, it may seem implausible that a brand-new maker of custom bicycles can hit the ground running with this degree of success. But the story makes more sense given their background. When Boston legend Independent Fabrication announced an impeding move to New Hampshire at the end of , most of their employees remained behind. Among them were friends Jamie Medeiros, Tyler Evans andKevin Wolfson, who decided to start their own venture. They developed a detailed business plan, Jamie and Tyler founded the company and hired Kevin, and on January 10, (at precisely 2:10pm, they tell me) Firefly was born. While the company itself was new, the skills and experience of those involved were considerable. At IF, Tyler had worked as a welder for over 13 years, Jamie for 14 years in R&D, and Kevin as a designer for 3 years. When Firefly announced they were open for business, orders began coming in straight away.





I first saw a Firefly bike at D2R2 last summer: two of them in fact. I remember it was an overcast morning, and when they rode past me I did a double take. While the bicycles themselves were quite minimalist, they were also unmissable: In the milky fog, their distinct graphics lit up in shades of green and violet much like ...well, fireflies. I noticed this again at the New England Builder's Ball last October: walking past Firefly's booth, their graphics flickered fetchingly in the dim light of the oddly cavernous showroom.





This "firefly" glow is in fact achieved fairly easily, through masked anodising. On titanium frames, different colours can be produced through anodising by controlling the voltage. The visual effect is surprisingly beautiful.





The unpainted titanium with anodised graphics quickly became Firefly's signature look, though other finishes and materials are available.







Most recently, the other materials on offer include bonded Ti-carbon: frames with titanium sleeves and carbon fiber tubing. As Firefly puts it, this is "technology usually reserved for the companies with million dollar R&D budgets, used by a company of three."






As the guys strung up the bike for me to get a better look, my eye kept going back and forth over the top tube. Something looked odd. I soon realised it was the expanding diamater. The top tube starts out skinny at the seat cluster, then expands until it's fat at the headtube joint, with the titanium sleeves shaped accordingly.






Less noticeable, the same thing happens with the seat tube, which starts out fat at the bottom bracket, gradually tapering until it's skinny at the seat cluster.





Between the tapering tubes and the carbon-titanium interaction, the bike, when examined closely, looks like a puzzle box, or anM.C. Escher drawing come to life.






The Firefly logo is carved into every titanium sleeve, like a bit of lacy edging.






And fans of colourful anodising have not been forgotten.





Being around Jamie and Tyler is a bit like looking at the mixed-materials frame. Somehow they click, despite seeming so very different. Jamie Medeiros has an old-fashioned European face that would not be out of place in a Renaissance painting. A big guy with fluffy hair, he moves around softly, almost stealthily. He often seems lost in thought or amused by something. He smiles to himself as he works.





Tyler Evans has a sharp and direct gaze. His movements are precise and quick. No question I ask seems to surprise him or give him pause; he is articulate and focused.






Watching them together - interacting by the machines, or drinking coffee in the kitchen - there is a synergy that is as effective as it is endearing. They sometimes give the impression of speaking in unison, or finishing each other's sentences. When working in close proximity, their movements appear synchronised.






This could go some way toward explaining Firefly's productivity. The shop space is organised with a separate station, machine, and tool for every task, arranged in the sequence in which the work gets done. Jamie cuts, prepares and notches tubes. Tyler welds. The smart layout and the rapport between the pair ensure that the works gets done in an efficient sequence, with as little time and energy wasted as possible.






Kevin is not in on the day that of my visit (he is baking bread, they explain - a culinary course), but I've met him before at local events and know that he completes the synergy. He is missed and mentioned often, as Jamie and Tyler discuss the shop and the business. Kevin is the racer, and every prototype bike gets tested by him in action.






In Firefly's range of offerings there are no model names, only descriptions of bikes and frame materials. They can build road, cyclocross and mountain bikes, or anything in between, or something different entirely. Recently they made aclassic randonneurring bikewith 6550B wheels and front rack. They have made upright city bikes. When I playfully ask about step-through frames they assure me that they would welcome such an order.






Hanging up in the "to do" corner, I spot the fabled monster cross frame that belongs to a local customer.






It is in for seat stay modification, to allow for a 650B conversion (built for 26" wheels originally).






Firefly's beautiful dropouts are machined locally by Cantabrigian Mechanics.






A few other bikes lurk in the shop on the day of my visit. Tyler and Jamie's personal bikes are there, as well as a new road build for review in Australian Ride Magazine.Several frames sit in fixtures in states of near-completion. A well-ridden mountain bike, its frame anodised in brown, hangs by the door. None of the bikes are my size, which is just as well, since absorbing the new shop is more than enough for my senses this time around.






It's hard to describe Firefly's shop space without appearing to be gushing. The place is - quite deliberately - a showpiece of interior design. Upon moving into the new building, Firefly gutted everything and started from scratch, hiring designer Alessandra Mondolfi- who also happens to be Tyler's wife - to create an interior to suit the company's needs and business model.






Firefly's space was designed to serve three distinct functions: as a workshop conducive to efficient fabrication, as a showroom for customers, and as a promotional space for both process and product.






The open concept layout is arranged as a series of rooms separated with sliding doors. At the very back is the roomy shop space, laid out much like a factory floor. Leading up to it are an office space, an inhouse photo studio,






a fit studio,






a kitchen and meeting room,






And a dramatic entryway that also functions as a rotating art gallery (currently showing work from Heather McGrath).






Strategically placed sliding doors and windows can make every section as public or private as necessary.





But aside from how the space is organised functionally, there is also a branding aspect to the design. It is difficult to point a camera within the shop without getting at least a part of the Firefly logo in the shot. Virtually everything - from the welding setup, to the fit studio, to the kitchen - has been arranged with documentation and media visits in mind.





The lighting is photogenic and atmospheric. The shop doubles as a stage.







The colour orange is carried through into all aspects of the space, from bar stools






to machienery,






to plant life.






There are unexpected installations. The moss bed not only smells wonderful, but is a great stress reliever - petting it feels wonderfully relaxing.






A modest DJ setup for parties.






Bits of stained glass to enhance the light streaming through the small windows. I'll refrain from posting pictures of the bathroom, but the theme continues there as well.






In an era when creating a strong brand presence and culture around your work is crucial, Firefly's purposeful approach makes for a fascinating case study. It is unlikely that their success is a matter of mere luck.






They work on building bicycle frames around the clock, sharing the results with the world as they go along through activity onsocial media and bicycle forums, building a loyal and ever-expanding following.






From the get-go, this was a part of their business plan, and they have followed through as intended.






Can the market for custom bicycle frames in titanium, stainless steel and carbon fiber sustain Firefly's practice? Impossible to know what the future will bring, but at the moment it appears the answer is yes.




The Firefly showroom in Boston is open weekdays 9-5 (no appointment needed). And, of course, you can also follow along online. Many thanks to Firefly for the tour and the chat. More pictures of the visithere.
