A Southeast Portland Adventure

I love it when a routine bike ride turns into something a little different.  This morning, with a promising break in the rain, I set out on my 1975 Centurion for what I thought would be my usual route out to Oaks Bottom and back to town on the Springwater Trail, with a brief stop at Tadpole Pond.  But, as I was getting underway, I could see that other COVID escapees had a similar plan.  My initial leg of the journey was crammed with pedestrians and other cyclists, as well as a fair number of cars.  So, en route I veered off course.

I headed south on SE 28th, past Clinton and Powell, and at that point thought that maybe a stop at the Crystal Springs Rhododendron Garden would be first up.  I cycled past the encampments which line 28th as one approaches the East Moreland golf course.  The course was fully stocked with golfers teeing off on its manicured greens, and offered a disturbing contrast to the disarray of the encampments just across the course’s fence line.  But, I kept my thoughts in check as I maneuvered the bike through the debris and then pulled in to the Rhodie Garden’s parking lot.  There were only two other bikes parked there, including a cargo bike with kid’s strider bike tucked neatly into its giant bags.

Unfortunately, once again everyone seemed to have the same idea as I did, and the Gardens were jammed with people taking in the serenity of the 9.5 acre park, with its teeming waterfowl.  So, I opted not to go in.  The above videos are from a recent visit (middle of the week, rainy day) when I was lucky to be one of just a few guests.  The birds featured in the 2nd video above are American Wigeons, a type of duck with an interesting, delicate call.

Upon deciding not to head down to Oaks Bottom, which I suspected would also be crowded, I meandered back into town going first north on 22nd from the Sellwood area, and then followed previously un-vetted (by me) cycling “greenway” routes back in to town.  As is sometimes the case with Portland’s cycling infrastructure, the recommended routes can be ill-conceived which I discovered when I found myself at the apex of a 5 way multi-lane intersection with no bike lane in sight.  Once I’d found my way again, I finally had a chance to see the Gideon Crossing, a structure which was built to accommodate cyclists and pedestrians waiting on railroad crossings.  This part of my route was at one time a section of my regular commute but I haven’t been out this way for about a year and a half.  I tried out the elevator, and then walked my bike across the bridge.  All worked fine, and the view from up top was fun.

Once back in town, I stopped off at one of my favorite local haunts, and a place that I miss now that “hanging out” is not an option.  Often there are interesting bikes (and persons!) parked out front.  Today it was quiet, so I ordered a latte and began a walk through the neighborhood while I sipped my decaf, in between re-masking whenever others were nearby.

And that’s when today’s special moment happened.  I approached an intersection that I ride every day on my commute, but I came at it from a different direction.  I caught a whiff of something extraordinary and unexpected during the height of winter:  the fragrance of jasmine, strong and powerful.  I looked up to see a lovely stone house with a front garden which has to be the envy of all its neighbors.  It was teeming with jasmine plants in full bloom and with ripe berries as well.  What a fantastic way to wrap up today’s journey.  In that instance, my trip turned into an adventure instead of a ride. The fragrance of the jasmine is still with me.

Vintage Mopeds and Scooters: the Precursor to e-bikes?

1962 VeloSolex moped

A lot of DNA is shared among vintage bicycles, motorcycles, scooters and mopeds.  Pneumatic tires, Bowden cables, chain drive, frame and fork geometry, as well as components including stems, seatposts, handlebars, grips and brake levers were utilized in common across these vintage machines.

I had an early introduction to scooters when my parents trucked home a Honda CT 90 to our rural farm back in the late ’60’s.  Once the little motorbike was off the flatbed, I was stricken with intrigue.  My parents made the mistake of “allowing” me to ride this little machine on the rural roads around our hay farm in the Applegate Valley of Southern Oregon.  At age 12, I propped my 9 year old sister on the back, and proceeded to ride far afield of my parent’s requirements, even crashing the bike into a ditch in a particularly unpleasant and embarrassing experience.  But most of the time, my spirits soared whenever I threw a leg over.  Even though I had my internal hub 3 speed bike to explore logging roads and irrigation canals, this gas powered machine allowed me to venture much further beyond the limitations of my little kid muscles and my clunky 3 speed Sears-Puch diamond-framed bicycle.

1897 Millet motorized bicycle

Motor-assist bicycles were first introduced over 120 years ago, back in the late 1890’s.  By this time in history bicycles were widely accepted and utilized for transportation, leisure and sport, but with the advent of the internal combustion engine (first developed in 1794) inventors made headway with adapting an engine to a bicycle frame. The above pictured bike utilized an air-cooled radial 5 cylinder engine incorporated into the rear wheel.  The rear fender doubled as the fuel tank.  It used a twist grip throttle, and could be started with pedals, much like modern mopeds.  The bike reached a maximum speed of 21 mph at 180 rpms.  The pedals served not only to start the bike up, but to provide for an alternative option should the engine fail.

Another fascinating approach to power assist on a bicycle was developed by Wall Auto-Wheel. First patented in 1908, this device could be added to any bicycle.  The 118 cc air-cooled single cylinder engine was mounted in a sub-frame which attached to the bicycle at three points.  There was a lever control at the handlebars which operated the throttle.  The whole unit was “lightweight” at 45 lbs.

1947 Whizzer Luxembourg

In the U.S, Los Angeles based Breen-Taylor Engineering developed the Whizzer bicycle engine in 1939.  This was a motor kit which could be added to any bicycle.  As you can see from the above photo, this was no small feat, and required many modifications and enhancements to allow this 150cc engine to perform with relative safety.  Whizzers were often added to the very robust American steel frames offered by Schwinn and others during this era.

After WW2, many different kinds of motor-assist bicycles entered the marketplace.  One of the most common was the “moped” which used pedals to start the bike and assist it on steep inclines when the engine was stressed.  While VeloSolex dominated the market in Europe, many other manufacturers stepped in to provide competition, such as this VAP model depicted above.

The above photo depicts Motobecane’s offerings from 1962.  French bicycle builders embraced the idea of motor-assist and many manufacturers offered mopeds and motor-assist bicycles.

But are these historic innovations really comparable to today’s e-bikes?  In some ways they are:  they attempted to take existing bicycle engineering to add motor-assist to the bike, thus extending the bike’s range and reducing fatigue for the cyclist.  Not all vintage motor assist bicycles incorporated the concept of rider pedal assist.  And, as is obvious now, gas powered engines, especially 2 strokes engines, are not environmentally friendly.  Are e-bikes environmentally friendly?  That’s an issue worth exploring, given that the batteries needed to power these bikes require harvesting materials that may have a negative effect on the planet.  That may be outweighed by a cyclist leaving their car at home and commuting on their e-bike.  And, the health benefits of riding an e-bike have been documented in numerous studies.  The behavior of e-bike cyclists was a concern for me initially, but I have noticed that here in Pdx, e-bike riders behave no differently than the rest of us, for the most part.  So, I say, if it has two wheels, get on it and ride!

A Portland Sunday on a Bridgestone MB3

My winter/errand bike has been a well used 1987 Panasonic MC 7500. I bought that bike as a frame and fork many years ago, and then built it into a Portland workhorse. Rigid lugged steel vintage “mountain bikes” serve as excellent platforms for conversion to a sturdy errand/winter/commuter bike.

The Bridgestone MB3 frame sat in my shop for a few months, as I had purchased it only for its lavender Nitto stem to use on my newly built up Rivendell Appaloosa.  Well, sort of but not really.  The Bridgestone frame was in great shape, and it kept staring at me every time I loaded another bike into the work stand.  Finally, I gave in, transferring many of the Panasonic components, which I disassembled, over to the MB3.  The build was pretty straightforward, and would have been completed much sooner had I not decided to use Suntour cantilevers, whose set up required more time.  Finally, the bike was ready for a few assignments.

Veggies loaded into my Jandd grocery pannier.

First, I headed over to the Montavilla Farmers Market.  This weekly Sunday event features an extravaganza of luscious fruits and veggies, homemade honey, jams and jellies, along with flower bouquets, wines, breads and baked goods, and some mellow classical guitar to accompany your shopping experience.

“Fancy Cycling”

Up and over Mt. Tabor

After dropping the veggies off at my house to stay cool on this hot day, I pedaled over Mt. Tabor and headed down to my local Powell’s bookstore on Hawthorne.  While there, I discovered this 2013 reprint of a 1901 cycling manual by Isabel Marks.  Major score!  The book contains instructions and photos on how to do some “fancy cycling” by performing tricks on your bike.  It looks like I have lots of work to do, as my track stands are not done while seated backwards in the saddle, one of the many tricks illustrated in the book, with period photos as illustrations of each maneuver (more on this book in a subsequent post).

The Bridgestone frame is a bit different from the Panasonic MC 7500 in a few ways:  the Bridgestone has slacker angles, shorter chainstays, a shorter wheelbase, and a longer top tube.  The Panasonic is a classic diamond frame, whereas the Bridgestone has a slightly sloping top tube.  While the Bridgestone is made from triple butted Ishiwata tubing, the Panasonic’s Tange Prestige double butted tubing feels a bit more lively.  Even so, both bikes are comparable and nice to ride, never feeling bogged down while climbing.  Below are photos of the components I selected:

Vintage Suntour bar mount ratcheting friction shifters

Suntour XC low profile cantilevers.

I re-used the original Shimano Deore derailleurs and the 12-28 Shimano 7 speed cassette.

I discarded the Biopace crankset, and replaced it with this modified Stronglight 99 with drilled rings. The crankset was originally a triple 52/42/32, but I removed the big ring and converted it to a double 42/32. I used the original Deore bottom bracket and front derailleur, and it somehow all worked out well.

Original Ritchey Vantage wheels on Shimano Deore hubs.  The wheels needed re-tensioning and truing, and the hubs were rebuilt and now spin smoothly.

Northroad bars with Suntour levers and shifters. The Suntour levers offer easily adjustable brake reach – a nice feature for riders with smaller hands.  A Cardiff leather saddle is shown in the background.

The 1989 Bridgestone MB3 as converted to a Portland commuter

While I’m not sure yet whether I will replace my Panasonic MC 7500 with this bike, I have enjoyed my experience so far.  The bike received some nice comments today from passersby.  It’s a good looking bike, and as configured performs just as I would expect from a quality steel frame and excellent vintage components.
