Electric bicycles, mushrooms and solid tires

Saturday I tried out an electric bicycle at Bicycle Outfitter (BO) and had a chance to discuss its prospects with the staff.

At BO, as with most bike shops, electric bikes are greeted with mixed feelings. I can relate to that. When a rider goes blasting by on an electric bike, I’m none to happy, then wish I had one.

However, electric bikes are already well established in China and are gaining a following in Europe. They have their place for commuting, the market they’re going after.

The bike I rode Saturday is a commuter with a top speed of 20 mph, if you’re just running on battery power and not pedaling. It looks like the typical commuter bike with a long wheel base, solid frame, motor in the rear hub. The battery is removable and sits over the rear wheel.

While the bike had heavy, durable tires, I wouldn’t ever want to have a rear flat. Were I to own one, I’d mount the new Tannus solid tire out of Korea. Solid tires have been around for decades, but this latest version looks promising. (One user’s experience.)

It’s lightweight and has decent rolling resistance, not as good as a pneumatic tire of course, but close enough. From what I’ve read, the only drawback is that it’s a bear to mount on a standard rim. It’s rated for 6,000 miles. That means it will probably last at least several years for a commuter.

So what about the performance rider who still wants go to electric? I’ve found two wheels that hold promise — the FlyKly and the Copenhagen. They’re similar in design and both have something else in common that has many buyers frustrated. The wheels were supposed to be available months ago.

As with any new product, production delays can be expected, and because there’s electronics involved, it gets more complicated. The product has to work flawlessly. If it doesn’t, someone could be injured and lawsuits would quickly shut down the companies.

While I won’t go into the details, I would be torn between which one to buy. The FlyKly appeals to the minimalist in me. It’s unobtrusive and weighs only 6.6 pounds. The drawback is that it only works with a single speed.

The Copenhagen is painted a garish red, weighs 13 pounds, but works with any standard road bike. Just swap wheels and you’re all set. Both wheels are wireless and require an app running on a smartphone, iOS or Android.

Once they come out, I’ll be interested to read the reviews. At about $700, they’re relatively affordable. For someone who commutes longer distances, they could pay for themselves in short order.

Meanwhile, with the recent rains my chanterelle friends have finally returned after a two-year absence. They’ll join me and spaghetti for dinner in the coming days.

Chanterelles are back after a long absence. They like rain.

Wurr Road bridge a sign of the times

November 18, 2014

Wurr Road's Pescadero Creek bridge makes it pretty clear you need to cross with caution.

Wurr Road’s Pescadero Creek bridge makes it pretty clear you need to cross with caution.


While I can’t deny Pescadero Creek bridge on Wurr Road in San Mateo County has seen its share of bike crashes, do we really need a sign suggesting that we walk our bikes across?

I first rode over the bridge with Jobst Brandt in 1980. He occasionally spoke of a huge crash here in the mid-1970s. Jobst and friends came flying down the road one frigid winter morning and the result was chaos as they skidded on the icy bridge.

Several riders crashed, broke bones, or were knocked out.

Today the bridge could use a little work, but better yet, replace it with something modern.

The good news is that few cyclists venture onto Wurr Road near the sleepy town of Loma Mar. Instead they stay on the busy Pescadero Road.

The fact that these signs just went up makes me wonder if there wasn’t another bike wreck here recently.

A road too narrow

The death of a 15-year old cyclist on Monday, October 27, on McClellan Road in Cupertino bothered me. I’ve ridden that stretch of road many times, mostly during weekend rides.

The fact that a double-trailer big rig was involved didn’t surprise me, although the location did. I’m sure those trucks are not supposed to be on McClellan.

I’m guessing the driver was shuttling between a construction site and the Permanente Quarry on Stevens Canyon Road and got lost or tried to take a shortcut.

I took a screen capture (to scale) of a similar truck and overlaid it onto the scene of the accident. It’s immediately obvious what could have happened. There’s just not enough room for bike and truck on that stretch of McClellan. The driver was turning right onto Bubb and was probably moving right after passing the cyclist.

What happened next is what has happened on more than one occasion. The second trailer struck the cyclist.

From what I’ve read, the Monta Vista High School student who died was an avid cyclist. No doubt that’s why he rode his bike to school.

If you think a double-trailer truck is bad, imagine a triple-trailer. They’re allowed on highways in 10 states, fortunately not California, although the truck industry has lobbied for it. Let’s keep them out of California.

While Cupertino has a great reputation for accommodating bikes on its streets, every community can do better. What happened Monday morning on McClellan shouldn’t happen again.

If you want change at MROSD, you’ve got to vote

October 13, 2014

Are you frustrated with the way things are over at the Midpeninsula Regional Open Space District (MROSD)? If you’re someone who feels shut out from the district’s “open” space, you should be. Now you can do something about it.

Two candidates, Mike Buncic (Ward 1) and Brandon Lewke (Ward 6) have made their positions clear: They want more open space opened and they’re proud to say they ride bikes.

If there’s ever a time when your vote matters, it’s here and now. MROSD board elections for four of seven wards are on the Nov. 4 ballot. Unfortunately, two are uncontested.

I’ve seen what a grassroots campaign for change can do. No entrenched elected official is safe. I was one of a small group of local residents in Menlo Park who banned together to vote out the city council incumbents in the mid-1980s elections.

One evening we showed up at a city council meeting, upset by a plan to increase traffic on our local streets. It was all a misunderstanding, but that wasn’t what mattered that evening. We were told by several entrenched city council members to take a hike. Big mistake.

I was so upset I took out an ad in the local paper and endorsed a candidate over the incumbent, who happened to be a cyclist. Didn’t matter. It was out with the old and in with the new. I could not have been happier that election evening. We said goodbye to the old guard and welcomed in the new.

If you want to learn more about Buncic and Lewke, check out their Facebook sites and read an article by San Jose Mercury News columnist Scott Herhold.

Lewke wants to preserve the Mt. Umunhum concrete silo. I’m all for that, just as long as we can get the road open to the summit, ASAP. None of us is getting any younger. I’ve been waiting nearly 30 years. It’s time for a change at MROSD. Go and vote!

Be sure to vote Nov. 4, especially if you're in a MROSD Ward with elections.

The Force Who Rides

It was only fitting: Back in May 1980, Laurence Malone wrote the definitive article about Jobst Brandt for Bicycling Magazine.

He never rode with Jobst, but as the country’s best cyclocross rider (6-time national champion, counting his Masters 35+ win), he knew exactly what it was all about.

It is offered here in its original wording as The Force Who Rides.

Laurence lives in Chimayo, New Mexico, where he rides on the area’s miles and miles of dirt roads. You can learn more about him by reading Cyclocross Magazine.

Three Feet for Safety Act goes into effect on September 16

After eight years of trying, California cyclists have an added measure of legal protection from motorists who take pleasure in buzzing cyclists, starting September 16. Don’t think for a minute that these buzz jobs are innocent oversights. They’re mostly intentional and they send a clear message: “Get the hell off my road!”

It’s a daily occurrence and one veteran cyclists live with, knowing there’s little they can do about it. That may change with this law, combined with actioncams like the popular GoPro used by riders in growing numbers.

I’ve had more than a few encounters that were so close the gap could be measured in inches, including several Santa Clara VTA buses. Now I ride with a Mobius actioncam, and while it won’t save my life, it could be used as persuasive evidence before a judge.

But back to the bill, signed into law by Gov. Jerry Brown in 2013. In essence it says, “A driver of a motor vehicle shall not overtake or pass a bicycle proceeding in the same direction on a highway at a distance of less than three feet between any part of the motor vehicle and any part of the bicycle or its operator.”

SB 1464 by Alan Lowenthal was vetoed by the governor in 2012 because it authorized drivers to cross over double yellow or double white pavement markings in order to provide the minimum three-foot clearance when overtaking a bicyclist. In his veto message, Gov. Brown noted that the bill could increase the incidence of head-on collisions for which the California Department of Transportation could be liable. That provision was removed.

Ironically, the city of Los Angeles sponsored Assembly Bill 1371 put forth by Steven Bradford, State Assembly district 62, which includes Gardena and surrounding communities.

I don’t think this law will change behaviors, but if it saves one life, it was worth the eight-year journey through the California state legislature.

Zoox has the right idea – no steering wheel

As I was writing Skidders, I imagined an autonomous car without a steering wheel. Not that it’s an original idea, but reality is just around the corner with the Zoox mobile. Meanwhile, Skidders is always available on Kindle, Amazon.com. Fewer typos than before.

Rocking and rolling at the Tour de France

RockShox would have come in handy at the Tour de France yesterday. Los Altos History Museum display.

While riding cobbles of the famed Paris-Roubaix route in stage 6 of the Tour de France may make for good TV, the participants were none too pleased.

Lots of racers crashed and we know the rest of the story. The course got cut short to reduce the carnage. So why didn’t the riders use front suspension or even full suspension?

It turns out they could and they have since 1991 when the original RockShox suspension was put to the test at Paris-Roubaix.

Greg LeMond used it and his French teammate Gilbert Duclos-Lasalle (Team Z) rode to victory on RockShox front suspension in 1992. After that lots of teams used them on the cobbles, but then they disappeared, later to return.

Bike Radar does a great job detailing the history.

Today they’re not used. I suspect the reason is that there’s not enough of an advantage with today’s carbon fiber bikes absorbing a lot of vibration compared to steel bikes. Not all of the Paris-Roubaix covers cobblestones. The extra weight and spongy suspension (some suspensions can be locked) slows riders down on the long sections of smooth road.

If you want to see the original bike used in the Paris-Roubaix and live in the South Bay, you’re in luck. It’s on display at the Los Altos History Museum, located right behind the library on San Antonio Road.

Bay Area natives Paul Turner and Steve Simons get credit for starting RockShox, now owned by Sram.

The bike exhibit “Pedal Power: From Wacky to Workhorse” runs through October 5. No charge.

Thanks to all who donated bikes. Several came from Vance Sprock, Cupertino Bike Shop owner.

Cupertino Bike Shop Open on Stevens Canyon Road

April 20, 2014

Cupertino Bike Shop has moved to Stevens Canyon Road.

Cupertino Bike Shop has moved to Stevens Canyon Road.

What a day for a bike ride, if you like perfect weather. I made it up to Skyline and enjoyed nice weather.

Riding past Stevens Creek Reservoir, I saw a mud puddle. It’s 13 percent full.

Stevens Canyon Road has a new bike shop, at the intersection of McClellan Road. Cupertino Bike Shop has completed its move from its old location on De Anza Boulevard.

Lots of buildings going up. If you type “Cupertino map” in Google you’ll see the new Apple HQ artistic rendering. The old HP campus at Wolfe and Homestead is almost all rubble now.

Speaking of building. I’m about finished with my first novel, Skidders. It’s about autonomous cars, hacking and how bicycles save the day. If you want an advance copy, just send me an email and I’ll send you a PDF.

San Tomas Falls shows its splendor

San Tomas Falls on the creek trail finally had more than a trickle on Feb. 28.

We finally had some rain. It was enough to put some life into San Tomas Falls on my ride home from work.

It might even turn the grass green on Mt. Hamilton. Last week’s Mt. Hamilton loop revealed one wildflower until Livermore. I’m not exaggerating.
