The Lanterne Rouge goes to Del "Chilly D" Miranda, who was last on every climb. But it wasn't easy... He nearly blew his perfect record by finishing just one second slower than Paul Capewell on Marin Ave. Had he beaten Capewell on Marin, he'd still have won the Lanterne Rouge award, but it would have been "tarnished." Disaster averted, he maintained comfortable last place margins on the two subsequent KOM climbs, Thorndale and Claremont/Grizzly/Vollmer. When making a bid for Lanterne Rouge, consistency is of paramount importance.
Bill Bushnell showed up on his super fast e-bike, with a new system. He's using a hub motor so he can regenerate to recharge the battery, but this means the motor will get very hot on steep climbs. He had to stop twice on Marin to cool, even with pedaling hard, but after that, the bike seemed to be OK. Bill doesn't post his times on Strava for obvious reasons, but I may be able to get him to share his segments. (ed. note: See Bill's comment below for accuracy and clarification).

Hi Paul,
ReplyDeleteThanks for organizing this year's event and for arranging the excellent weather.
My objective this year was to complete the course on the bike. It's a tough test for a hub-motor'ed e-bike with a legal power limit (750 watts at the wheel). I was faster on the climbs in 2015 with a through-the-gears system.
Although I had a couple of extra cooling aids in/on the motor (ferro-fluid and heatsinks), I had to stop a number of times to allow it to cool: four times on Marin, once on Lomas Cantadas, and several more times at various locations along the course. Average motor temperature was 83C, and for 55 minutes of running time the motor interior was >100C, which reduces overall efficiency.
The hub motor drive system has some distinct advantages in spite of its unsuitability for a Nifty-like course: (1) quieter than a geared motor, (2) simpler drivetrain--fewer critical parts to fail, (3) more efficient than a geared motor provided the terrain is not extreme (e.g. grades <10%) and provided regeneration is employed efficiently, and (4) motor (regenerative) braking solves a long-time problem I've had overheating my friction brakes, both rim and disk, leading to blown off tires, rapid disk brake pad wear, or busted spokes (caused by the howling of an overheated disk brake system).

Bill, Thanks for the comments and clarifications, and the sharing of the Strava file. Seems like the hub motor is overall a far superior system, as long as the climbing is not severe. Based on your comments, it would seem a hub motor with a 2 speed internal system would be a good idea, but not sure there is a big enough market for that, and it would likely be very expensive.
ReplyDeleteCrystalyte used to sell a direct-drive hub motor with two sets of windings, one for speed, the other for torque, or so it was marketed. Assuming one uses a capable controller the most important aspect is the copper fill, so the unused set of windings is just dead-weight.
ReplyDeleteIf I want to climb Marin more efficiently with a DD hub I've got a couple of choices: (1) get a bigger motor, or (2) lace the same motor into a smaller wheel. (1) means giving up a rear cluster and going with a single speed, and (2) changes the bike's geometry and handling more than I'd like.
A third option is to run two separate systems, a through-the-gears (TTG) for the steep terrain and a DD hub for the rest. But, that adds complexity and weight. My bike already has too much stuff on it.
As for "far superior", I'm not sure I'd go that far. Although hub motors are still popular in commercial e-bikes, TTG systems are gaining popularity, esp. those using OEM drive systems by Shimano and Bosch where high torque at low-speed is desirable.
To get an idea where the market is going, take a look at the offerings at one of the larger Bay Area e-bike dealers:
https://www.motostrano.com/E-BIKES-electric-bicycles-s/4468.htm
Although I admit to a small amount of "novelty bias" as I explore the limits and capabilities of a DD hub system, I am for the moment happier on balance with the DD hub.
Thanks for sharing this post. I'm very intersted in this topic. Bundaberg vets Most of us insure issues which might be beneficial and in addition essential to us comparable to our residence, automobile, and even our lives, so it's solely comprehensible that we'd want to prolong the identical safety to our pets.
