Portland Bikeshare 2.0 – E-bikes!

Many cities have gone to e-bikes for their bikeshare programs, and Portland is one of them.  Its first bikeshare launch several years ago was pretty much a bust, although PBOT and the Biketown folks will certainly never admit this.  Those bikes were clunky, bad handling, heavy, and exceedingly unpleasant to ride.  I used that system exactly 2 times, swearing to never ride them again, and as I love to ride all kinds of bikes, that should tell you something.

In early September, the “old” fleet was decommissioned (not without some controversy), and the new e-bikes hit the streets.  The new system is run by Lyft, which will be a familiar platform for many city dwellers who use ride share.  The launch experienced some unfortunate timing problems:  dangerous wildfire smoke enveloped the city for many days, causing a temporary shut-down of the new bikeshare program, then torrential rains and winds followed shortly thereafter, meaning that no one was biking in Pdx.  But finally, clean air and good weather returned, giving me the opportunity to test out these bikes in Portland’s ideal fall weather.

My first test ride was totally unplanned:  I came across a stable of these bikes on one of my noon walks, and decided spontaneously to hop on and go for a ride.  The process was very easy.  I downloaded the Biketown app, scanned the code on the rear fender, and bam! the bike was unlocked.  Before doing this, I checked all the bikes in this line-up for the one with the best feel on the brake levers and tires, and checked to make sure that the seatpost clamp would hold (something I learned from my prior and limited experience with Portland Bikeshare).  The bikes are tall, and weighty – somewhere between 75 and 85 lbs, according to various web sources.  They feature a front disk brake and rear drum.  The gears (using a continuously variable rear hub) are controlled by a simple grip shifter.  The drive train uses a chain instead of the unpleasant shaft drive on the previous models.  The power is always on, and theoretically delivers juice based on the cadence and force on the crank.  The front and rear lights come on once the bike is underway.  There is a minimal front rack (more on this later), which is (over) rated for 25 lbs.

On my first ride, learning how to unlock the bike wasn’t immediately intuitive.  I tried pulling the cable straight out, but it wouldn’t budge.  Finally I jiggled it a bit and it broke free.  Once out, you put the locking end into the pink “holster” shown above, while riding.  When you are ready to terminate the ride, you park the bike (properly  – more on this later!) and secure it by putting the lock back in place.

The Schwalbe tires were fine, offering some shock absorption, but the bike did bounce around and rattle a quite a bit while underway. The front-end handling of this bike is vastly improved over its predecessor, but even so it wants to fall into corners and is wobbly while getting underway, a fact made much worse by its sit up and beg riding position which doesn’t allow the cyclist to weight the bars for control.  Even so, slowing down while approaching stop lights, I was able to avoid putting a toe down (a long ways down it is!) for the most part, so slow speed handling is not bad for such a heavy machine.  While stopped with your foot down, the bike’s front end will flop over, so you have to actively keep the fork pointed straight ahead it to keep it upright.  The battery is mounted on the sloping downtube, and contains some very simplistic instructions on how to unlock and lock the bike.

The bike’s front rack is too small to hold a standard sized brief case, and the very tight bungee cord supplied will squash your bag and possibly even damage its contents.  Fortunately, I was using my “vegan” brief case which can take extreme abuse, as shown above, and still bounce back to normal.  There’s no bottle cage mount, and the rack itself is shallow.  Riding with a bag, even my lightweight one shown above, adversely affected the handling and made the front end more ponderous than in its unladen condition.  I smooshed my water bottle in, and hoped that it wouldn’t pop out while underway, which fortunately it did not.

Biketown does not provide any technical data regarding these bikes, except perhaps upon request, but I have been able to determine that the rear hub is a Nuvinci continuously variable unit as licensed to Enviolo.  I don’t know what groupset this is, but I did feel that the gear range provided was adequate for the steep hills I encounter on my usual routes.  You move the grip shift forward to lower the gearing, and back to ride in higher gears.  Shifting was seamless, as expected, but power delivery was very uneven.  On uphill stretches, it seems that the motor only responds to a higher cadence rather than to pressure on the cranks, which I found out while trying to get myself up Mt. Tabor.  Pedaling an 85 lbs bike up a steep hill with very little power assist is the stuff of muscle strains, as I found out the next day.  Finally, when I shifted to a REALLY low gear, the power kicked in and I was spinning away to the top.

Braking performance was adequate, but with such a heavy bike it takes longer to stop, so planning ahead is needed when approaching stops.  The rear brake was almost useless, but the front performed reasonably well on the four different journeys I took.  You’ll notice the difference in the feel of the brake levers – they are clearly operating two different kinds of brakes.  I worry about less experienced riders not understanding the extra time needed to slow down, especially in emergency situations, and given that average speeds are much higher on e-bikes.  But, there’s no danger of doing an endo on these machines.

The Biketown app is user friendly and intuitive to use.  When you want to ride, you open up the app and up pops a map of the bikes available in your area.  The app shows battery life (in miles) for any bike you click on, and also shows you the number of minutes estimated to walk to the bike of your choice, which you can reserve in advance if you want.  That, so far, would be completely unnecessary, as virtually no one is currently riding these bikes.  The above shows a recent screen shot taken from my iPhone app.  The map contains no legend, which turned out to be an important omission, potentially costing a lot of money to unsuspecting riders (see more below).

Pricing of rides has been controversial.  For the four rides I took recently, I spent a total of $15.60 and traveled a mere 7 miles.  At 20 cents per minute (without $99 membership fee which lowers the price to 10 cents per minute), I also racked up extra $1 charges whenever I didn’t park the bike at at “station”.  Even though the instructions on the bike say it can be parked at any “public” bike rack, there’s a $1 charge whenever it is not left at a “station”.  The map on my iPhone doesn’t clearly identify stations, but even if it did, parking the bike wherever one ends up is the ideal situation, and I think it’s unfortunate that the Biketown folks decided to tack on this extra charge, as it reduces the bikes’ usefulness as an alternative to other transport modes.

To determine whether you should spring for the $99 annual fee, I created this formula, where X represents the breakeven number of rides and Y = the average number of minutes per ride.  In the formula below, I’ve set Y at 15 minutes, which then yielded 40 rides per year as the breakeven for buying a membership:

(15*.2)*X+(X*1)=99+((15*.1)*x))

My last ride of the four I took on these bikes ended unpleasantly.  I wanted to ride the bike home, and park nearby.  Of course, there are no public racks in Portland’s residential neighborhoods (but clearly there should be).  So, the next best thing was to leave the bike in Mt. Tabor park, locked up to a sign post, but away from the right of way for pedestrians.  As it turns out, I was charged a $25 fee, later waived, for parking in a “no parking zone”.  How do we know it’s a no parking zone?  As I said, there’s no legend on the map, but I finally learned that anything outlined in red is a no parking zone.  So, beware, and study your map closely before locking up.

All of which is counterproductive to the whole idea behind these bikeshare programs. If the goal is to reduce driving, I can’t see that happening with this program, except for maybe the short “last mile” jaunts or quick trips near someone’s workplace.  If the goal is economic justice and greater access to transit for low income populations, these bikes fail on three counts:  stations are non existent along large swaths of north and northeast Portland, the cost is astronomical compared to public transit, and the bikes are not capable of hauling groceries and work tools.  While they do go faster than regular bikes, that efficiency is quickly lost in the time it takes to locate and walk to one of these bikes. The lack of available helmets, combined with the extra speed and ponderous handling characteristics raises safety concerns as well.

I do think that e-bikes represent a great opportunity to get people out of their cars and moving for transit, but I don’t see bikeshare as a way to optimize this.  Someday, I may own an e-bike, and be glad for it, but in the meantime I’m planning on enjoying my vintage, lightweight steel machines, with their wonderful performance and superb handling.

 

 

1950 Raleigh Sports Tourist – 45 lbs of Riding Pleasure

2016-07-29 007

I recently cycled home from work on my 1950 Raleigh Sports Tourist.  The bike had been sitting at my office for a while.  One of the reasons I haven’t ridden it with greater frequency is that the full chain guard (“gearcase” for those who speak British) and the drive side crank arm contact each other with an annoying noise with each pedal stroke.  Previously, I had tried to solve this problem by mashing various parts of the gearcase with my hands to see if I could force it into a different position that would provide clearance for the crank arm.

2016-07-29 008

As I was noisily making my way up Clinton Street, I came upon a rider on a Mercian.  We chatted for a while and I learned he was riding an early 80’s model that a friend had given him as a frame (nice gift!), which he then built up.  That’s only the 2nd Mercian I have spotted in Pdx, aside from my own.  Interestingly, because my Raleigh is geared so high, I ended up surging past him in my big (but lowest) 52 gear inch as we began to climb the steeper hills, and so we parted company.

When I arrived home, sans heart attack, I put the bike into the shop stand, determined to solve the gearcase/crank arm clearance problem.  The first thing I did was to mark the position of the axle in the dropout and the adjuster on the shifter cable.  This way, I could restore the wheel and cable back to their current position – something which took a while to perfect so that the hub shifts correctly.

2016-07-20 005 2016-07-20 006

One thing I’ve gotten questions about before is how to get the gearcase off the bike.  There are two pieces at the back of the gearcase which can be removed by unscrewing the bolts which attach them to the main part of the gearcase.  After that, there is a bracket which attaches the gearcase to the chainstay, plus a bolt which holds the front part of the gearcase, and attaches near the bottom bracket.  Once those are removed, then it’s a matter of re-positioning the gearcase and sliding the opening at the back through the narrowest part of the drop out.  The photos above show how this is done.

2016-07-20 001

Once I had the gearcase off, I took my mallet to it and tried straightening it out a bit.  Then, I tried various methods of altering the position of the gearcase once I re-mounted it to the frame, but nothing worked.

2016-07-29 010

Finally, I took my files and filed away a small section of the metal on the inside of the crank arm, to provide more clearance.  I didn’t want to take a lot of material off.  But with these solid steel crank arms, I probably have nothing to worry about.  Ultimately, I was successful in adjusting the gearcase cover to eliminate any contact with the crank arm.

2016-07-20 003 2016-07-20 004

Since I had the pedals off, I thought it might be time to overhaul them. Their last overhaul was 8 years ago.  Sure enough, the grease was pretty dirty.  Fortunately, the brilliant design of the cone and lock washer made the process incredibly quick and easy.  The tabs on the back of the cone make it simple to adjust the cone to perfection.  Once adjusted, the cone’s tabs lock into position with the grooves on the lock washer.  If your adjustment needs a tweak or two, just loosen the nut and move the cone one notch at a time.  If only all pedals were designed this way!

I headed out on the bike today and thoroughly enjoyed not only the new, silent drive train, but the amazing ride quality of this bike.  The steel frame and steel wheels absorb road shock very well, so that even the upright riding position does not transmit pain waves to your spine.  With the inertia of the heavy steel wheels, the bike really rolls once it gets going.  In my high gear, I have even passed a carbon fiber bicycle or two, much to their riders’ surprise.  The components, the paint, and the attention to detail in every aspect of how this bike was manufactured puts modern quality control to shame.

The bike responds to pedal strokes and never feels mushy or bogged down.  The geometry is perfect for the type of bike it is, and it does not wobble at slow speeds and provides for fun descents and excellent cornering at high speeds.  In fact, the ride quality of this bike is a sharp contrast to another 45 lb. machine I recently rode – the SoBi bicycles which are part of Pdx’s new Biketown bike share program.  Those bikes are made with large diameter aluminum tubing, and also feature an upright riding position, although much more extreme than that of the Raleigh.  The stiff aluminum frames, bad geometry and questionable component quality provide for a really unpleasant riding experience.

It would be fun to see a bike share program which used quality vintage bicycles and de-emphasized modern technology (which serves as a barrier to those who cannot afford the latest internet device) as a way to introduce new riders to urban commuting. There are so many quality vintage bicycles out there. Find one and ride it!

Portland Bike Share – 1st Ride on the 1st Day

2016-07-19 010

With Portland’s typical giddy fanfare for anything bicycle related, the city’s bike share program went live today.  I had tentatively planned on attempting to test ride one of these bikes today, and as it turned out, all of the day’s mishaps led to my first ride on one of these orange monsters.

2016-07-19 003

I was down at South Waterfront awaiting an annual doctor appointment which went awry.  My physician’s schedule got seriously backed up so after waiting for too long, I had to reschedule and move on to my next appointment.  But, while I was cooling my heels in the waiting room I had time to download the Biketown app on my iPhone and go through the steps to set up an account and review the process of renting the bike, which at first seemed kind of daunting.  Thankfully, the app worked perfectly so that when I exited OHSU to the street level to feast upon the orangeness surrounding me, it was very easy to enter my codes into this solar powered key pad and unlock the bike from the rack.  Unfortunately, the bike I unlocked turned out to be unrideable.

2016-07-19 013

The bike’s quick release for the seat post binder bolt would not hold position because the nut on the bolt could not be turned to tighten it.  Lacking any tools, and knowing that I was not willing to damage (further) my knees with a too low seat height, I put the bike back into its rack and forfeited my $2.50 rental fee.  Then, I checked the seatpost QR’s on all the other bikes in the rack and found that they similarly could not be tightened adequately to hold the seatpost, until I finally spotted my ride – an orange monster parked askew with the seat post jacked way up.

2016-07-19 014

So, I entered my codes again – a very easy process that involves an account number plus a PIN, unlocked the bike, slung the lock into its holder on the left side, tossed my brief case into the front basket (which is very narrow), and started to get underway.  During this process, several cyclists approached me and asked about the steps involved in renting these bikes and how the system works.  I did my best to educate them with the tiny bit of knowledge in my head at the time.

2016-07-19 007

Then I mounted the 45 lb. machine, which involves pushing your leg above the lowered top tube rather than throwing a leg over and which actually seems harder to do.  Immediately I noticed the terrible handling – a result of ill conceived frame geometry for a bike which is designed to carry its weight on the front.  The bike wobbled around as I got underway, and I felt like a novice cyclist rather than the experienced rider that I am.  Once moving, I was okay, but anytime I put my foot down the bad geometry kicked in and the bike weaved from side to side. But, as with any bike, you can adapt to strange handling characteristics with enough saddle time.  I’m not sure I really want any more saddle time on these bikes, though.  My 1950 Raleigh Sports Tourist, which also weighs 45 lbs is an absolute gem in comparison, being well balanced, easy to handle, and with an amazingly comfortable, if upright, riding position.

These bikes, provided by Social Bicycles, aka SoBi, are equipped with a shaft drive and an internal Nexus 8 speed hub.  Having not ridden a shaft drive before, I was curious if I would notice any particular differences as compared to a chain drive.  And, I hadn’t tested the Shimano 8 speed internal hub, so I was also curious how this component would perform.  Since I needed to head over the to east side of Portland, that meant taking the Tilikum Crossing‘s mild but long hill in my work clothes.  These bikes have no bottle cage, so even if I had a water bottle, it would not be readily accessible.  Riding east over the bridge, I was passed by ALL cyclists, and a few called out to ask me how I liked the ride.

I found the shaft drive to feel fairly normal, but the Nexus hub seemed to have a lot of inefficiency in the lower gears.  I only engaged the 4th and 3rd gears of the hub, but those gears felt so compromised that I ended up stomping up the hill in a higher gear so I could avoid the sluggish feeling that the hub offered in the lower gears.

2016-07-19 008 2016-07-19 005

The Kenda tires were fine and seemed to absorb some road shock, but the High Nelly upright position made my back hurt right away.  The drum brakes required a lot of force to stop the bike quickly, making me think “whoa, Nelly!”.  At least there would be no danger of doing an endo on one of these machines.

2016-07-19 009

By the time I got to the east side of Portland, I couldn’t wait to scan the horizon for the first orangeness I could spot.  I ditched this bike at a Bikeshare rack along the Max line, and continued the rest of my journey via public transportation, having spent a total of $3.60 to rent the bike, and now spending another $2.50 to continue on my journey.  While on the bus, I sent an email to customer support to alert them to the seatpost QR issue.  A few hours later I received a response letting me know that if you encounter any mechanical issue with a bike, put it back in the rack and hit the “repair” button on the keypad and the bike will be taken out of service until the issue is resolved.

Who are these bikes for?  Well, maybe Nike can answer that question.  Portland is unique in that its Bike Share program is not funded with taxpayer dollars, but rather relies on the millions received from corporate sponsors.

Possibly, these bikes could be useful for inner city users who need a quick jaunt to areas not covered by public transportation.  The apps provided by SoBi worked extremely well for me, so the barriers to use involve not technology, but lack of access to technology.  And that will be my final criticism for this program.  Who is it helping?  Those who don’t really need help at all.
