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...

what is the exact use of a front camera for “daytime riding on the road?” (I understand your secondary use case ;) )

there would be no meaningful difference between the axle and chainring - the effort of spinning a lightweight metal ring isn’t going to even be measurable. there’s also a clutch in these motors between the cranks and the axle (otherwise you’d get the sensation of the motor turning the pedals...

this is a possible use for an eBike, but it’s also a possible use for having the correct gearing for your climbs. you can either add power (requires a motor,) or go slower (requires gearing appropriate to keep your cadence up when crawling up a hill…)

for me this is definitely a solution looking for a problem. never had a problem with a presta. maybe an issue in the MTB world?

the actual torque from the motor is 23nm max. they scale it up for marketing purposes because most of the time a mid-drive is actually geared way up by the bike’s chainrings and cogs - imagine you’re riding a mid-drive with a 50 tooth chainring up front and you’re in a 20 tooth chainring in the...

local businesses here often vigorously oppose bike infrastructure when/if it means losing on-street parking. they claim that while people on foot and bikes do shop in their stores, they don’t buy as much as people who drive. this is a stupid point of course, the amount of cheese or coffee beans...
