great wheels for the creo 1! loved them on mine.

that isn’t quite as easy to verify as it sounds, since at a given cadence, speed, drag, and slope, there is only one possible amount of rider power Pr for a constant E. at the same cadence, on level ground, you could ride in several different gears to achieve different speeds with different Pr...

it’s been a while. everything but motor power is in the data file you get from mission control (or whatever it’s called now lol) that can be parsed with anything that reads XML, which is basically anything. i probably used excel. there are also lots of free converters for FIT files and the other...

here’s the one that’s most handy, it’s actually closer than i thought ! i should find the xls. the gold is the ratio between rider power and motor power, at four different assist levels with max set to 100% to avoid hitting the limiter, so to speak. at the time we believed that it was always...

I went back and read this https://support.specialized.com/kb/sp_en-us/content/ECV3-6142/03-Turbo-Vado-SL-2-Turbo-SL-System which has lots of cool info. it’s clear that the previously described assist ratio (the 2x you etc) was either an approximation of a range of values… or they changed how it...

what am i seeing in this photo? it’s really a great shot, color, detail, composition and so on but i can’t for the life of me figure out what it is!!! scale of the water spray suggests its small, but it looks like … ice or snow?

i probably would too... if i looked at motor power much during the ride! in part to harmonize the experience between bikes i don't look at motor power much any more. cadence, rider power, pedal balance, heart rate, speed, ride time, that's really all i want and need. i have the displays set up...

it's really not that complicated !! how much does the motor help you, as a function of how hard you pedal... and what's the MOST it will ever help you. as far as i know every decent torque-sensor system from the big manufacturers works the same : in the mission control days, specialized...

has anyone tried the insta360 cameras? the x5 seems really impressive, captures a big super distorted 360 spherical image and then has it's own software to edit it down to natural (sort of?) looking videos.

nah, it demonises the particular type of bicycle that the term describes IN THE NETHERLANDS which is the powerful motor, beefy frame, the buddy seat (from which little pedaling could ever be done), and yes, fat tires. the dutch are a precise people, and they are allowed to coin or adopt terms...

ken, in the past years you've made these same points over and over, specifically referencing 727, dr currie, people for bikes, and so on... dozens, if not a hundred times. at some point any sane individual truly committed to a cause (if they are interested in results, not just hearing...

i don't have much of a dog in this fight, but i just have to ask : are the people who write this media morons? or are they trying to be obtuse? or am i a moron? this is very confusing. first they list two types of e-bikes. 20mph ones and then 28mph ones, which they say are treated similarly to...

i’m sure there are apps don’t upload their data anywhere, or they can be told not to, but most do store ride data somewhere on the cloud. not sure what the risk there is, personally i don’t care if some hacker someday expends a lot of effort to know what my heart rate was on a bike ride! i like...

agree with your conclusions - but let’s be clear about the facts. he was convicted. had he not been elected president he would have been sentenced.

i mean … i personally do it every day and have designed a few million square feet of office space in a couple major cities around the world in which bicycle parking is required. i use this one every day, added at a very low cost to a building from the 1960s. some excerpts on the history of...

the head tube wouldn’t have complied with the old 3:1 aspect ratio rule. UCI changed that to 8:1. anyway, don’t believe everything you read on the internet - a little knowledge is a dangerous thing. Ridley uses an almost identical frame for non-e-bikes.

park it in the bike room at the office. required by law for major buildings in many civilized places. fits about 40x as many parking spaces per square foot as automibile parking.

we had a bit of the same problem with left-wing / progressive Americans cities. fox news, republican politicians, and right wing social media characters go on and on about democratic failure to govern and provide public safety. but the facts are very, very different, particularly for San...

just get a left crank arm with meter, super simple swap and very easy, ant or Bluetooth. stages, 4iii. Bulletproof. $200 or so, including an ultegra crank arm. I don’t think they put them on deore cranks.

there are still tons of them here, probably the most common single brand. but a successful business isn’t just about volume, you have to make a profit on each (or most) item over a sustained period of time. almost 10% of their current liabilities are unpaid tariffs!
