Poles (Bollards) on Paths are a Hazard for Bikes

Poles (technically called bollards) are often placed on bicycle paths at entrances and bridges to keep automobiles off of the bicycle paths. The unintended consequence is to put the bicyclist in danger of crashing into the pole. This type of accident is very common. The poles are especially dangerous for people riding at night (the reflectors are only effective if you have a bright light), for triks, racing wheel chair riders, and people that tow tag-a-longs and/or trailers. The problem of cars driving on bicycle paths is not even a problem that needs solving as I have never known of a case of a car colliding with a bicycle on a bicycle path even though most paths are not "protected" by bollards.

It has also occurred to me that the problem of bicycles crashing into bollards at night could be greatly reduced by mounting flashing LEDs on them. They could be powered by a super capacitor changed up during the day by a solar cell mounted on top. The reason for the capacitor instead of a rechargeable battery would be that it could last virtually forever without replacement.

Recumbent

Currently, I am researching recumbents and am seriously considering getting buying one. They seem to be a bit of a novelty as I have rarely seen them on the road. There are so many different companies and models available. I have a hunch that most of them that are sold are not riden much. People buy them because they are attracted to the soft comfortable seats annd don't realize it still takes hard work to get it to move. Because of the low volumn the prices are much higher than conventional bicycles. Actionbent seems to be the "Dell" of the industry. They sell direct from the internet and have great prices.

Distributed Transportation System

As I read about how the current NY mass transit strike has impacted the entire city, I see yet another argument in favor of bicycles for transportation. Any centralized transportation system like a subway or airport hub can easily be disrupted by accident or malicious intent. Either can even be shut down by a phone call threat. The Internet was created by the military to decentralize communication and make it more robust and reliable in the event of a war. If a hub is down for whatever reason, your email is automatically routed around it to reach its intended destination. Similarly, roof top solar panels make us less dependent on the electrical grid and central power plants. In contrast, our transportation system is much too vulnerable to single point failure. Subways and airports are the worst, but cars are not much better. Cars can give people the illusion of power and independence, but as we recently experience when the recent hurricane took several critical refineries off line, they are very dependent on a centralized petrochemical infrastructure. A bicycle based transportation system is completely decentralized and robust.

Home Before Dark

Most people think that the shortest day of the year in near Christmas, which is true. However, the day that the sun starts stops setting earlier and starts setting later is closer to December 9. At my latitude the earlest sunset is about 5:17pm. I can just make it home without needing my headlight if I leave work at 4:45pm.

December is the month that most people quit riding to work. If you can survive December, chances are you can make it all the way though to March and join the exclusive club of "hard core riders" that laugh at our "sunny weather" brothers.

Bicycle Lights

Several people have praised bicycle generator lights. The problem is that the most powerful ones only light a tiny 3 watt halogen light bulb. This can help you be seen, but it is not nearly bright enough to light your way on a dark street. If they made it bright enough to be really useful, it would have too much drag. I use to commute with a 15W halogen bulb with a rechargeable battery, but have recently upgraded to a 30W system. White LED lights are not very bright and not that much more efficient than halogen lights, but they do last a long time and hold up to vibration. They are bright for the first 10% of battery life and then get dimmer, but stay on for a long time. The very expensive lights are HID (High Intensity Discharge). The main downside is that they need to warm up to reach full brightness and they cost $300 and up. I would love to see a low cost, efficient, and bright bicycle light made with a Compact Fluorescent bulb. It would have 4 times the battery life of a halogen and hold up to vibration.

Commuter Bicycles

updated 12/11/2005

Commuter Bicycles

a.k.a Transportation Bicycles, City Bicycles or Utility Bicycles

www.commuterbicycle.com

The vast majority of bicycles sold today are Mountain bicycles. For street use these bikes are much more comfortable than the skinny tired Road bikes (racing bicycles) that forced the cyclist into an aerodynamic but awkward position with bent over handle bars. The upright position of a Mountain bicycle is not as efficient, but it allows better situation awareness and control when riding in traffic and is more comfortable. As it turns out most people riding Road bikes end up not using the "drops" on the bar, but position their hands on the top which defeats the aerodynamic advantage* and places their hands far away from the brake levers. However, using a Mountain bicycle to commute has several disadvantages: The weight, cost, and energy dissipation of a suspension system designed for rugged off road riding, exposed greasy chain, high rolling resistance of fat tires with knobby tread, and more likely to be stolen.

Many companies are now starting to market bicycles specifically designed for commuting, transportation or utility as opposed to recreation. This new type of bicycle that is emerging doesn't even have a standard name yet, but I prefer to call it a Commuter Bicycle. It took over 10 years to settle on the name of "Mountain Bike", so this is normal in the fragmented bicycle industry. When I started this site in 2002, there were only a few companies chasing this market in the USA; now there are dozens. The features to look for in a Commuter bicycle are upright seating position, low top bar, full reflectors, cargo racks, bells, fenders, chain guards, kickstands, gearing for moderate conditions, internal gearing in the rear hub, some mild suspension, built-in generator lights, and nutted bolts instead of "Quick Release" disconnects on axles and seat posts (to discourage part thieves). A feature just now starting to appear is a sealed drive shaft or belt instead of a chain. Both of these need to be used in conjunction with internal gearing.

Internal gear hubs, These are much improved over the 3 speed hubs of the 70's. Shimano, SRAM and Sturmey-Archer just introduced 8 speed versions. The 7 speed Shimano Nexus has a range of 244% which is better than the old 10 speed derailleur bikes and very adequate for general riding. The new improved 8 speed has a range of 307%. They are low maintenance and easy to use. You can shift while stopped or under load and the gears are all in order and evenly spaced. No more "the big gear is low in the front and high in the rear". Beginners who don't recall high school physics often have trouble with this and tend to stay in one gear. Internal gear hubs are much more intuitive. After using conventional gears for 30 years, I adapted to the Nexus 7 internal hub in 3 minutes.

Drive Shafts (chainless) , This is the only company I know of manufacturing these. The drive shaft needs to be combined with an Internal gear hub since a chain is no longer available to switch gears. I believe this is the future for all bicycles.

Off-the-shelf Adult* Commuter Bicycles:

Breezer is a new company specializing in commuting bicycles that was founded by one of the inventors of the mountain bike, Joe Breeze, who has had an interest in transportation bicycles for over 30 years. He was featured in the September 2003 issue of Bicycling Magazine. They have 6 fully equipped models (Town, internally geared: Uptown8 $850, Uptown $770, Villager $670, and Citizen $500; Range, derailleur-geared: Liberty $960, Greenway $740) and 3 quick-fold compact models (i7 $700, i3 $399, itzy $450). The Breezer Town bikes are similar to European town bikes, but are lighter and more widely available in the USA. I bought a Villager for my wife and we are very happy with it. Breezer had a big head start on the commuter bicycle market in the USA, but now the big international players are moving in fast. One of my readers praised the built in lighting system in the Uptown.

Zero City Bicycle is a commuter bicycle that combines a drive shaft with an internally geared hub. Unfortunately, it is only currently marketed in England. Last time I checked they offered to ship it to the US for $885 including freight. This is the nicest bicycle manufactured with the shaft drive that I could find. They are looking for US based distributor. I test rode a demo model for 3 months and was impressed). I did no maintenance and had no problems.

Incline Bicycles makes the Cruz7 and Cross7. Both have a shaft drive, 7 speed internal gearing, and front suspension. The only difference is the Cruz has metric 70cm wheels and the Cross has 26 inch wheels (compatible with Mountain Bike Tires). They don't come with racks, fenders or lights, but they retail for as little as $400 and are an outstanding value at this price. The only shop I know if that sells them in the USA is a small store dedicated to transportation bicycles and advocacy. They will gladly add any accessories you want. They are also sold from a website.

Dynamic Bicycle makes the Runabout which is very similar to the Incline with the same Susex shaft drive and Nexus 7 speed hub. It is sold directly online from a new company based in Boston for $549.

Broadway Bicycle is a semi-custom bicycle made by a unique bicycle in Boston. It is basically an old fashion English 3 speed with modern components that sells for $425. A custom bike builder named Mike Flanigan builds them a full custom version of it that sells for $900. He owns a company called Alternative Needs Transportation and specializing in building bikes for commuting and carrying cargo. He will probably build you any bicycle you want if you can't find anything here.

Koga-Miyata Town and Country Bicycles are now being imported to the USA. They are hand built in the Netherlands. They are expensive and heavy, but extremely high quality and well built to last many miles and years. They are some of the most expensive bikes in this category.

Biria is a German bicycle manufacturer that is rapidly expanding in the USA. Almost all their many models qualify as Commuter Bicycles. See their website for their extensive list dealers. They have "city" bikes that range from $400 to $700. New for 2004 is the very innovative "safety bicycle" which features a locking system, ABS brakes, the new Nexus 8 speed and a shaft drive. There is a good online source for these bikes.

Specialized just introduced the Globe model in 2004. It is listed at $770, but has been discounted to $670 less by at least one store. It comes complete with rack, fender, built-in light, and lock. It has a conventional 24 speed drive train.

Bianchi Milano is the first modern Commuter bicycle and it is made by a large and famous Italian company. It is sold world wide. It is a very beautiful and elegant design that is competitively priced.

Kettler is a German company that makes a high quality City Comfort model that sells for $1200. They also sell many quality plastic trikes for kids. You can buy them online from the Bike Mania link below.

Fuji produces the Osaka and Sapporo models, which they sell in Europe. They continue to refuse to market them in the USA and have only promised to correct their website, which implied that they were available. I am very disappointed in Fuji.

Trek just introduced an entire line of commuter bicycles in 2004. They are not probably stocked in your local store, but can be ordered. At the high end is the $990 L300 that features the new Shimano 8 speed internal geared hub. Fuji's loss is Trek's gain. The 3 people that I know that purchased the L200 model and have been very happy with them.

Giant introduced an all new bicycle they call a SUB (Sport Utility Bicycle). This is very exciting because this is a major international bicycle company and they are offering this bicycle in the USA. You can buy it buy special order through almost any bike shop stocking Giant. I really wish Giant would have named it a UB.

Burley Runabout is made by the company famous for their quality $400 bicycle trailers. Because just about every bicycle store distributes the trailers they can all get you this bicycle for $1099. It lacks a chain guard and fenders, but has disk brakes which are great for the rain.

REI is a well run sporting goods co-operative that has a large network of stores as well as a strong web presents. They feature a large cycling department in addition to camping gear. In 2005 they introduced an "urban bicycle" called the Novara Fusion for $700 that is close is specifications and price to the Breezer.

Cannondale is a great American bicycle company that designs bicycles and builds the frames for a very impressive line of transportation bicycles that they refer to as "Street Bikes". Their premier bike features the Roloff 14 speed internal hub. Unfortunately, they only market them in Europe. Cannondale is now in bankruptcy not due to this mistake, but because they wasted considerable resources trying to develop and marketing off-road motorcycles. Please order you bike from Europe and help save this great company. We only need to get them to promise to stick to bicycles!

Kona, a company founded on Mountain Bicycles is introducing a new line of bicycles in 2004 called Dew that is targeted at commuting. Not surprisingly, they look like Mountain bicycles without suspension. Interestingly, the website states that these bikes are the ones that the Mountain Bicycle designers ride to work. This sounds like an admission that Mountain Bicycles are a poor choice for basic transportation:) Anyway they do make the best 20 inch wheel kids bicycle on the market for $240. This is the bike I ended up buying for my 7 year old.

Kronan, distributes a simple, reliable and durable bicycle that is based on the classic Swiss Army bicycle design. It is made entirely of steel except for the aluminum pedals and weighs a hefty 46 pounds. The List price is $359. They are sold from the corporate website as well as a dozen independent dealers across the USA.

Electrike, is an electric motor assisted tricycle for the fun loving young at heart person who doesn't have the endurance or balance to ride a bicycle. It comes with an extra large basket and fenders and is a great way to get around inside a gated community.

What every you do don't buy a bicycle from Hol_logo_88X31_v1 or 1121_Affil_eGift_120x60. These store have great values in many product lines, but their bicycles are not good values. The bikes are heavy, have many parts that are prone to rust, and not very serviceable. Feel free to buy other items using the links above, but I wouldn't recommend a bicycle for transportation from them. Consumer Reports came to the same conclusion in their report on bicycles.

Bicycle Security: I was able to finally convince my employer to build a secure bicycle parking lock, which is basically a covered fenced area with combination lock. The best way to lock a bike is with a U-lock connecting the frame and a pole or other object embedded in concrete. You should also consider registering your bicycle with State or Local government along with the National Bicycle Registry. At the very least keep a record of the serial number stamped on the bottom.

Do-it-yourself Commuter Bicycles:

It is also relatively easy to add accessories to just about any bicycle to customize your own bicycle. I recommend starting from a "Hybrid" or "Comfort" bicycle. If you start from a Road bike, you will need to change the "drop" bars to mountain bike bars which also involves replacing shifting and brake levers. This modification can get expensive, but worth doing if you already own a Road bicycle. If you start from a Mountain bicycle, you should replace the Knobby tires with Street tires. Here are some good on-line sources for fenders, mirrors, bells, and racks:

Spinning Crank Supergo Bike Shops

I have bought many parts over the years from Performance and have been very happy with them. Their sale prices are usually outstanding. Supergo now owns Performance and sell whole bikes as well as parts. If you order from my links above, I get a 5% fee. All of my profits go to bicycle transportation advocacy (I run this website as a public service and hobby)

Tires: Mountain bikes all come with 26 inch wheels. Most Road bikes now come with 70 cm wheels (metric), which have replaced the older 27 inch wheel. 70 cm wheels are about 27.5 inches. The diameter is not nearly as important as the tire width. I would recommend getting tires close to 700x35C (70 cm diameter 3.5 cm width) or 26x1.5 (for Mountain Bikes). For Mountain Bikes it is especially important to get tires that are designed for street use. The tread on Street tires is designed to roll smoothly and quietly on hard surfaces. Kevlar belted tires and Self-Sealing tubes help avoid punctures, but in any case it is wise to always carry a mini-pump, spare tube, patch kit, and a few tools.

Mirrors: Mountain Mirrycle Bar End - $15. Once you ride with a nice mirror like this, you will never want to go without one. I have received some feedback that some riders are happy with mirrors that mount on glasses or helmets. My main point is that a mirror is an essential commuting accessory. For a great web page on mirrors, you can click here.

Handle Bars: Expensive mountain bicycles tend to have bars that are just as uncomfortable as road bicycles in order to put you in an aerodynamic, but awkward position. It is best for commuting to have mountain bike style bars that flare up. These are commonly refered to as "riser bars". Some riders do swear by the road bike style bent over or "Drop" bars. They like them because they can vary their hand positions on long rides and can ride faster. This could be important if you have a long commute. Experienced riders can quickly go from an upright position for comfort to an aerodynamic position with quick access to brake levers to . Some people even add a set of break levers in both positions called Runkel levers that are starting to be popular in Cyclocross circles. Also, many people never adjust to Drop style bars because their frame is not properly sized for their body. The bottom line is that if you are flexible and willing to pay for a custom frame and 2 sets of brake levers, you may enjoy Drop bars. For the rest of us with commutes under 5 miles, I recommend mountain bike style bars that flare up.

Brakes: V-Brakes are great for commuting. They have plenty of cable travel which keeps them in adjustment longer. They also have clearance for fenders and good stopping power for wet conditions. They need compatible levers. Disk brakes are now somewhat available and even better, but are not so common or standard and spare parts could be a problem in the future. They also require special wheels.

Fenders: Planet Bike Freddy Fenders. Most stores can sell at prices lower than the factory website (This pricing is intended to support local shops- they also support advocacy with 25% of profits). I ride year around with fenders even though it doesn't even rain much where I live. They help to keep grit off you and your bike.

Seats: Of course, this item is highly dependent on personal preference. It is also very analogous to purchasing a bed. If you spend a large amount of time on your bike it is important as well. Please also be aware that, like a mattress, softer is not always more comfortable over the long haul. The seat I prefer is the Hobson.

Head Light: Best value is to buy the midrange models (about $100) from either VistaLite, Crygolight, Niterider or Planet Bike. A 10W Halogen light is a good balance between brightness and power consumption. A HID (High Intensity Gas Discharge) light is about 3 times brighter and a Halogen with the same energy and great if you ride at night in foul weather, but will cost over $300. Hopefully, white LED (Light Emitting Diode) headlight technology will soon be perfected. The "white" LEDs are not nearly as efficient as the "red" LEDs and lose brightness rapidly after about the first 10% of battery life. The brightest LED based headlights are still too dim for my taste. The advantage of an LED is that it is efficient, compact, insensitive to vibration, and will never burn out. Some bikes I have listed above have generator ("dynamo") powered lights. These tend not to be very bright and don't work when stopped or going slowly. Some of them are not regulated and will burn out bulbs at high speeds. The advantage is you never have to worry about a battery running out of power for long commutes. The newer models feature secondary LEDs that remain on during brief stops by the energy stored in a capacitor.

Rear red LED flashing light: VistaLite - $10. Cateye 500LD - $10. Red LED lights are fantastic and very efficient because only light in the red color is created (as oppose to creating white light and adding a red filter). A blinking red light is even more efficient because it is off most of the time and attracts as much attention of a much brighter steady light. If you get a model with AA batteries, it should last several years (400 hours of use). Some of the rear lights like the Cateye will work well as reflectors when the light is not on or your batteries are dead.

Bells: Bells with a thumb lever can be bought for $5 and are great to warn pedestrians and slow moving bikes of your approach. To warn cars you can get a $20 Delta Airhorn that you can pump up with your bike pump. It makes you sound like a semi-truck or a train.

Pedals: Very few people who try clipless pedals ever go back to toe straps. Two sided platform SPD pedals make it convenient to ride with street shoes or bike shoes. The clipless pedals are safer than straps because they release like ski bindings in an accident. The problem with clips and toe straps is that can scrap if you have them down and they don't allow you to get the force from "pulling" unless you have slots in your shoes, which can be dangerous if you have to get out fast. I don't believe any company even sells slotted shoes any more because of the popularity and superiority of clipless systems. I would recommend the Shimano PD-M545 for $90 (or the generic Nashbar NS-DHPS for $30 if you can't get yourself to spend more than you paid for your first bicycle for a pair of pedals.)

Cargo Capacity: I highly recommend a rear rack and panniers (technical bicycle term for "saddle bags") that can be purchased from the above sources. You can shop for price as these items are non-critical. Panniers are much more comfortable and convenient than a back-pack unless you have a very sort distance to cover. If you have more to carry, you can use a Bob or Burely trailer. Some people do rave about the Xtracycle add-on, but I still think it is a bit of a kludge. One of my readers found that Two Wheel Gear Commuter Pannier made carrying his dress clothes to work much more practical for him. I just roll my clothes up and set them in a conventional pannier.

Note: I compiled this website after months of fruitless web searching for a geared bicycle for my 7 year old son to commute to school with that was not a Mountain Bike. I never found a youth bike for him, but I found plenty of adult bikes that I feature above. If anyone knows of any off-the-shelf internally geared youth bikes I am very interested. Breezer promised to introduce a model in a few years and Fuji sells one in Japan and Europe.

PS. Special thanks to Ralph, John and many others that emailed me suggestions and improvements to this webpage.

* The drag coefficient of a bicycle and rider doesn't become significant until speeds of over about 15 mph. As an experiment, I rode the same route multiple times with my 20 lb road bike with an aerodynamic body position and with my fully loaded 40 lb commute bike with an upright seating position. My average time for my 13 mile commute was reduced by 8 minutes from 50 minutes down to 42 minutes.
