Mechanical doping and the future of e-bikes
James T wrote this 1 month, 28 days ago.
I posted about lightweight e-bike designs back in April. At the time, I jokingly remarked in a discussion group on LinkedIn that, “the way I am riding this spring, I could use a little electric boost to bridge the gap in the local Tuesday night training rides”. I may have been kidding, but apparently I wasn’t the only person thinking that way.
Listening to the May 20th episode of the Velocast podcast, I first heard the term “mechanical doping” used to describe a hidden electric motor in the seat tube of a racing frame. In the podcast, they mentioned that the UCI was investigating allegations that lightweight Gruber Assist motors may have been used in bikes raced at Paris Roubaix and the Tour of Flanders. Over the weekend, an article in Bike Biz discussed the matter further, quoting a former pro who claims to have “ridden a 10 kg pro bike with an electric motor housed in the frame at the crank.” After the Bike Biz story broke and a video surfaced, rumors that Fabian Cancellara may have ridden the Spring Classics with a motor in his bike spread quickly on the web. Today, even Cycling News and VeloNews are addressing the issue. The latter even has a statement from Cancellara about the accusation- “It’s so stupid I’m speechless, I’ve never had batteries on my bike.”
This blog is about bikes, not racing, so I generally avoid mentioning the various scandals that seem to plague cycling as a sport, and in this case I am certainly willing to give Cancellara the benefit of the doubt. In a post over at Cozy Beehive, Ron points out a few of the reasons that he does not believe that Cancellara used a motor to cheat. I’ll let others discuss whether he did or didn’t, but what interests me out of all this mess is the technology that makes the accusations believable. To learn a bit more about the Gruber Assist motor, you can download a PDF document from the website. The product, which is billed as an “invisible ascent aid”, promises “200 watts more motor power” and “up to 100% performance increase for 100 min. maximum.” The motor is suitable for retrofit in any bike with an inner seat tube diameter of 31.6 mm. An external battery pack is required, but it is certainly conceivably that a cylindrical NiMH battery could be hidden somewhere in a carbon frame making the system completely invisible from the outside.
My first thought upon hearing these latest rumors was…what does all this mean for electric assist bikes? Certainly if the “mechanical doping” (I still love that term) stories are true, it is bad for the sport of cycling. Lets face it though, pro racing has its share of other problems at the moment, so the possibility of a new way to cheat shouldn’t really come as that big a shock. Applied to other types of cycling though- commuting or even recreational riding for instance- a product like the Gruber Assist motor could be helpful for some people. Someone who wants to get out and ride for fun and fitness but is intimidated by the hills might feel more confident knowing that he or she can get a boost of speed with the simple push of a button. Likewise, a lightweight motor could appeal to a potential bike commuter, who might want to speed though one section of his or her route quickly to avoid traffic or hills. Those are just a couple of examples. The reasons that this type of technology might appeal to some beginning or “non-enthusiast” cyclists could go on and on. So I am wondering…if pros really are now using e-bikes to cheat, will that change the perception of electric bikes as a category among hardcore cyclists? Will the most elitist roadies no longer sneer at “geeks” who speed by on electric bikes? Maybe this whole mechanical doping scandal is just what the electric bike industry needs to finally catch on in the U.S. market? OK…I am not being completely serious, but you do have to admit that this latest pro cycling scandal does cast electric bikes in a different light. Outside of the word of sports, the idea of saving energy to cover more ground at a greater speed might be not be such a bad thing for some people. It certainly beats the idea of taking EPO for the morning commute.

Four For The Weekend

Seoul cycle design competition 2010
James T wrote this 2 months, 2 days ago.
Several readers have emailed me lately suggesting that I post a link to the designboom post about the Seoul Cycle Design Competition. I actually already mentioned it, but it was buried in a post full of links, so I can see how many people didn’t notice it. The competition has three categories: cycle design, infrastructure and fashion accessories. It is free to enter and the deadline for registration is July 5th, so get started working on your designs. You could win a portion of the $46,000 in prize money that they will be giving away.
Earlier this week, I briefly mentioned the new sub 700 gram Cervelo R5ca frame. Bike Radar gives us a first look at the new bike. Nice! I can’t wait to see what the “clowns” at Chrome Hearts do with this one.
Also at Bike Radar, I noticed these new 190 gram Look Keo blade carbon pedals, which use a carbon leaf spring in place of the traditional wound metal spring. The pedal surface is significantly larger too, which is something that I really like (by the way, I currently use Keo pedals on my road bikes because I like the larger platforms).
Quickrelease.TV ask the question, Can art get more people on bikes? Any thoughts?
Finally, I will mention this Bike Portland post titled, 100 miles on a tall bike. I don’t have anything to add, but I wanted to pass the link along because I just couldn’t stop looking at the “Peleton” picture. I have just never seen a paceline of tall bike riders in Lycra…quite a sight.
For all of you reading in the US, have a great Memorial Day weekend.

Concept bikes by Omer Sagiv and more
James T wrote this 2 months, 4 days ago.
Omer Sagiv is an industrial designer who currently works for Ron Arad in London. He sent me three of his conceptual bicycle designs, which you can also check out on his blog. Some of his sketches in particular are worth a look.
I was sort of shocked to see this collaboration between Cervelo and luxury fashion brand Chrome Hearts. It didn’t really seem like something Cervelo would do. Well, it turns out they didn’t. This tweet from Gerard Vroomen makes that pretty clear. In real Cervelo news, the R5ca “Project California” road frame was recently unveiled.
Bike Rumor points out the new Trek time trial bikes, which feature Kammtail Virtual Foil shaped tubes. The compartment behind the seattube is a nice touch.
Designboom posted about the book, Velo: Bicycle Culture and Design. They include some great photos in that post, so definitely check it out.
Finally, I will mention this electric assisted recumbent tricycle by Revolution Cycle Company. According to the description, it is a lean-steered and features “a canopy, seasonally adaptable nylon skins & seating, and flatbed storage.”
My Assault on Mt. Mitchell
James T wrote this 2 months, 5 days ago.
This blog is focused on bikes and cycling products, so I don’t really write about my rides very often. Yesterday though, I finally had the chance to do a ride that I have wanted to do for a long time, so I will take a break from design content to discuss my first Assault on Mt. Mitchell.
The Assault starts in nearby Spartanburg, SC and ends at the summit of Mt. Mitchell, which at 6,578 feet is the highest point east of the Mississippi River. The ride covers 102.7 miles with a cumulative elevation gain of around 12,000 feet. That sounds tough, but what makes it more difficult than other centuries with similar elevation gain is the fact that almost all of the hard climbing is in the last 20 miles (see the elevation chart below, which I borrowed from Scott Simmerman’s excellent account of his first Assault). The first 80 miles, from Spartanburg (elev. 781 ft.) to just beyond Marion, NC (elev. 1,289 ft.), are relatively easy. There are a few small climbs but mostly just steady rolling hills. On the north side of Marion though, you pass Lake Tahoma and start gaining elevation as you approach the Blue Ridge Parkway. The grades gradually start to increase and at about 3 miles from the Parkway, the really tough climbing starts with a series of extremely steep switchbacks. At mile 85 (the number six rest stop), you have gained elevation, but are still at only 2,308 feet. Turning onto the Parkway at mile 86.7 though, you are suddenly up to 3,365 feet. That’s over 1,000 feet of elevation gain in less than two miles! Crazy steep roads like that and relentless climbing are pretty much what you get for the rest of the ride. It levels off a bit on the Parkway…even going down for a couple of very fast sections, but any elevation that you lose has to be made up in the final few miles. I was actually sort of relieved when my GPS battery died on the Parkway at around mile 90. I was tired of looking down to see that I was still below 4,000 feet, knowing that I would have to climb another 2,500+ feet in the last few miles. At nearly 98 miles, you turn off the Parkway toward Mount Mitchell Park, and those last 5 miles are brutal. Like the other riders around me at that point, I felt like I was barely moving forward, swerving a bit, and just trying to will myself to the finish line at the top.
Each year, the fastest finishers complete the Assault on Mount Mitchell in just over 5 hours…a time that just amazes me. I went into the ride this year without a time goal in mind; simply finishing at the summit was my only goal. When I signed up to do the AOMM in February, I planned to train for it and make a strong showing…but other things came up. Between work and family responsibilities, I never got in those long training rides that I had planned to do. As it turned out, May 24th crept up on me and I found myself in worse shape than I had been in previous years at this time. Prior to yesterday, my longest ride of the year was around 35 miles and I hadn’t done any real training for the climbs. Suffice it to say, I felt extremely unprepared to take on a ride like the Assault. I was already registered though, so I wasn’t about to back out. I knew it would hurt, but I planned to just take it slow, ignore the pain, and finish no matter what. Instead of looking at my watch and pacing myself, as I would normally do on a ride like this, I decided to just ride at whatever pace felt comfortable. I slowed down to chat with people early on and I stopped at all the rest stops to eat a snack, refill my bottles, and thank the volunteers (it is a very well supported ride with many SAG stops staffed by very nice volunteers). Taking it easy was the right approach. Even though the final climbs were difficult, and at times I felt like I was barely turning the pedals, I actually felt pretty good at the finish. After the bus ride down from the mountaintop, I even rode a few more miles on the flat roads of Marion to loosen up my legs.
I would definitely recommend this century to anyone looking for a challenge, but it is also worth doing just to experience the natural beauty of the area. As I was riding (slowly at times) on the Blue Ridge Parkway yesterday, I was reminded of why I love the southern Appalachians so much. The weather was not perfect… it was a bit foggy with rain off and on. Even though the views of the surrounding mountains were not as good as they could have been, everything was lush, green, and beautiful. That smell of the forest in bloom after the light rain was something I really appreciated too. At one point on the Parkway, I rode out of one of the dark tunnels to see the rays of sunlight filtering though the trees and fog. I stopped to move a black snake from the middle of the lane and took the opportunity to just look around for a minute at the light rays and the trees and the mountains. At that moment, it really hit me how lucky I am to live in an area with such incredibly beautiful riding. It also made me think about why I love cycling so much in the first place. It really is a great feeling to get far away on a bicycle and just enjoy the world under your own power. I guess moments like those are a good contrast to the times yesterday when my legs were hurting, I was barely moving, and I felt like I would start rolling backward if I stopped pedaling for a second. In retrospect though, even those parts of the ride were good. Overall, it was a great day and I am REALLY glad that I finally did it. I hope to ride the Assault on Mt. Mitchell again next year too. Who knows…I might even actually try to get in shape for it.
