Dock-less Bicycles - the final piece of an urban transportation infra-structure.

Have you driven in Seattle recently? Or tried to find a place to park? Driving into the city is an ever more challenging undertaking. Shared, dock-less bicycles may be the final piece of the solution for those who want to just park their cars in favor of alternate transportation.


I saw my first dock-less bicycle technology late this summer while walking in the south Lake Union area when I wandered past randomly parked neon colored bikes - lime green, orange, and yellow. Each had a unique rear wheel lock and digital QR code.




Shared bicycles have been around for years, but were inconvenient being limited by the need to rent (and return) them at established docking stations which were often blocks away from where you wanted to start or finish your ride. This was a major factor in the limited use of the Seattle Pronto bike share program which in turn led to its bankruptcy earlier this year. 


Now GPS and wireless wheel locking technology have changed the game for bike sharing.


In a hurry to get to the bus? Grab a bike. Late for an appointment? Grab a bike. All you need is a smart phone, a dock-less bike app, and a credit card.


First step - find a bike. The smart phone app points you to the location of available bikes, usually within a few blocks of your location. 


Then take a short walk and find the readily identified neon colored bike. 


Finally, scan the individual QR code on the bike with the smart phone camera, and as you provided a credit card when you activated the app, it is remotely unlocked.



You now have a bike to ride to the destination of your choice. When you arrive, park the bike anywhere and re-engage the lock - and no additional hassle to find a docking station.

You will be (painlessly) charge a dollar per half hour of actual use.

Lime Bikes (one of 3 pilots in Seattle) launched its pilot in July, 2017, with 2000 bikes and intends to expand to 10,000 bikes within a year. The other two pilots (Orange and Yellow bikes) have similar plans.


This exponential rate of growth of dock-less biking around the world has revitalized the dying bicycle manufacturing industry in China. Planned production to meet dock-less cycling bike demands is estimated as equivalent to 50 percent of the whole industry’s current 2017 capacity.


As with all new technologies, there are a few challenges to fix before we reach the final product. 


You need to bring your own helmet (it is the law in Seattle, although loosely enforced). Too many parked bikes on the sidewalk will soon become clutter rather than convenience so the city needs to bring some rationale to where they can be left. And finally there is the issue of breakdowns and theft.


I predict dock- less bikes will be the "disruptive" technology that is going to change how we get about in our large and congested cities. They are the final piece in the urban transportation puzzle, faster than walking and cheaper than Uber.


Assuming the problems with car congestion and parking continue to get worse, I think we are seeing how we can implement a bridge to span the gap between walking and the fixed rail/bus systems for longer distances. As well as a great solution for short distance trips to the local grocery store.

A Winter Program to Maintain Your Summer Fitness.

The days are getting shorter. The weather is getting wetter. Now is that familiar winter challenge: working in a daily walk or run to keep in shape until finally Spring returns. Finding a free 15 or 20 minutes in a busy day has always been a challenge, but it is definitely easier than finding an hour to visit the gym. 

Here are a few ideas to maintain your fitness until the grey skies part in Spring. And as a plus the same exercise routines can be used to help you maintain fitness during a busy time at work or a summer vacation. 

A balanced exercise regimen has three components - strength training, cardiovascular fitness, and osteoporosis prevention. 

Strength (Resistance) Training (15 minutes 3 times a week) 

You don’t have to do a gym workout with heavy weights to maintain muscle tone and strength. Just the idea of working out with free weights (or machines) is daunting and a definite barrier to starting a regular resistance training program. 

So how about using lighter weights? 

A recent study proved that lifting relatively light weights can build equal strength and muscle size. Instead of using 90 percent of your personal one-repetition maximum for 8 to 10 repetitions, you can drop the weight to 50 percent of your one rep maximum for more repetitions. Twenty-five repetitions. Three sets. Three times a week. 

The key to improving strength is to stress the muscle to the point of complete fatigue. You cannot do one more repetition. But more reps of lighter weights gets you the same benefit of fewer reps with a heavier load. 

A switch to lighter weights will also mean that you can now use your own body weight as an exercise load (rather than free weights at the gym) to maintain your strength. If you are interested in suggestions for exercises you might do at home, here is a place to start: https://www.nytimes.com/guides/well/strength-training-plyometrics

Cardiovascular (Aerobic) Fitness (5 minutes, 3 times per week) 

Numerous studies have shown that just a few minutes of High Intensity Interval Training (HIT) at an intensity approaching your maximum capacity produce the same metabolic changes in the muscles as those found after hours of running or biking. 

HIT strategies are built around the use of episodes of intense activity alternating with brief periods of recovery. An intensity that will leave you sweating and short of breath, 8 or 9 on a discomfort scale of 1 to 10. 

Although intervals have traditionally been done on a treadmill or stationary bike, many activities can be adapted to HIT. For example, you can increase the pace of a walk, especially if you are going up a slight incline, or periodically add in a short bout of walking stairs. Twenty seconds of intense activity with a 10-second recovery break. Three sets. Three times a week. This appears to be the shortest interval workout that maintains CV fitness. If you are looking to improve, then additional repetitions for longer periods are necessary. 

Osteoporosis Prevention (2 minutes, daily) 

Osteoporosis prevention should be part of any health maintenance exercise program, especially for women. While strength training keeps the ligaments strong, it is jarring, impact activities that stimulate bone strength. Running will work, but that means getting into your gear and going outside. If you have a treadmill, that works as well, but you need to jog not just walk fast. 

Additional options for indoor impact activities include hopping (one foot or two), jumping jacks and jumping rope. And if you want to up the intensity, try some HIT credit as well.  

Daily, two sets of 60 seconds each will do the trick. 

So there you are. Just 10 to 15 minutes day will help you maintain your summer fitness. Alternate strength and CV days, and end each session with a few minutes of hopping or jumping. Here is the hard part - building it into your daily routine. 

Extra Credit – Stretching 

Flexibility should really be on your list as well, but it is generally not considered a “fitness” activity. Being flexible decreases the odds of injury from aerobic and resistance training. Yoga, pilates and passive stretching (no bouncing as you try to touch your toes). But do wait until AFTER you are warmed up to stretch, and don’t force it.
