also.… the addict e-ride is a very nice bike, maybe pick up a used one? it’s essentially the bike you are trying to build yourself. notice that 1) you can’t even see the motor and 2) the chain stays are substantially reinforced relative to the regular addict. the additional dimension also...

they’re serving a very different market, with nothing even remotely as light as the X20 that @Katrina92 is trying to improve on. The X20 weighs 1.39kg. a typical hub might weigh 200g, so the delta is more like 1200g. I am not aware of anything else that light, and while it’s bigger than a...

electricity, on the other hand, is already up to 40% renewable, 35-40% depending on the source. solar has been doubling every few years. electrification is occurring almost everywhere, and while yes, it’ll take a while, yes, it’s also inevitable. current growth rates suggest 50% carbon-free...

this is a very strange result - among the billions of words spent by cyclists debating wax and lube i have never heard of using both - it's widely acknowledged that wax and lube don't mix. they literally don't mix. the idea here that the wax would stay on the outside of the lube and keep the...

same, many quality lithium ion batteries go way more cycles than promised.

sounds like your LBS and specialized will have it sorted! the input that the motor is most efficient at higher cadence is absolutely true - but it should reliable and smoothly deliver power all the way down to the lowest cadence you can keep rolling at. efficiency does drop as your cadence gets...

your post seems a little contradictory - do you want exercise while commuting, or do you just want a fast easy commute on a bike?

nothing of course ! but i’d say the manufacturer’s intent (which does telegraph in lots of small decisions about the bike, as well as bigger ones like geometry) matters. the vado SL (and non-electric cousin sirrus, which we have a nice example of) is marketed as a fitness bike, or hybrid...

it would be another advantage if the flow rate was high enough to not need to do that, but i’m guessing the physics doesn’t really work out. i seat my tubeless tires with one of those air shot cannisters, a clik adapter for that would be cool. it only takes a few seconds to take the valve core...

i know a few people who intentionally file their e-bike rides as bike because there are so many fewer "e-bike" segments. this is really inappropriate since most non-e-bike riders like to chart their progress / speed on segments against both their own results and the community. strava flags...

i'm a strong believer that if you're riding for pleasure, you should use the motor absolutely as little as possible. everyone can define "possible" differently. if your round trip to get to a vista is 50 miles but you only have two and half hours, then you need the motor to boost you from 15 to...

specialized themselves seem a little confused about this, they list it as a road bike. but then they say you can’t use tires smaller than 38mm on it, and market it heavily towards gravel. of course lots of people are using road-size tires and it works just fine. a lot of creo owners are/were...

i keep forgetting that the creo is no longer a road bike, kind of wild that it comes with those tires!! drop bars to go fast on pavement but tires to go slow lol.

check out bicyclerollingresistance.com ! they have tests on rollers at 18mph for a zillion tires. the results wouldn't apply to rough/gravel/uneven surfaces but are a decent proxy for good california roads. here are watts of resistance (at two diff pressures, to see more pressures you need to...

it's probably obvious from your work, but does the model take into account the huge difference in tires? something like a 47mm pathfinder has more than twice the rolling resistance at 18mph as a state of the art road bike tire. roughly 44 watts of RR vs 18 watts for a pair of tires (47mm...

you guys should all know that it’s considered very bad luck - tempting fate - to talk about never getting flats 🤪

at 20mph i’d say 20% is about right for an aggressively fitted creo. i do see a lot of creos with tall spacer stacks, riser stems, and riser bars, which obviously all works against the theory. with mission control’s power readout you can pretty easily simulate this, find a flat road and go 20...

it’s fun to ride fast, no doubt, but when that last 100w only gets you 2mph… i never used turbo either except for short stretches of very steep hills, and one time i bonked after not eating or drinking on an 80 mile ride.

lol, i get that … but what’s it for? watching after the ride, safety, ??

I’m familiar with Ed’s posts. I am not sure that his use case - mid 20mph speeds for an hour or two with <100w rider power - are really very indicative of what almost anyone else would experience on a creo, 1 or 2. really nice guy, but some of his claims about aerodynamics, the relationship of...
