What are some inexpenssive hub motor kits that /n/ would reccomend?

The cheapest ones go for 250$ on Amazon and AliExpress, are they worth buying?
20 replies and 2 images omitted. Click here to view.
Hub motors (direct drive) are 10/10. No service, can be overclocked.
Mid engines can't be overclocked, since they are too compact, and heat will build up there quickly, causing magnets to go kaput.
Also, chains and shit are annoying, requiring unnecessary service and losses (which are more important, than extra torque on e-bike thanks to batteries being shit).
>He doesn't push 80A on start for extra torque needed
THing is, they are 250W only on paper, because muh laws.
In reality even shitty motors on electric scooter are 500W continuous no problem.
To show the pussy she'll never get to lick
What you do is take the e bike battery, fill up your bathtub, get in the water, then drop the battery in with you.
36V is not enough. 56V is enough but it won't do anything. Anything above - people don't make such e-bikes because they know wiring is shit there, and getting shocked sucks

Post new rolling stock and lines that have just been / will soon be opened.

Pic related is a brand new CAF tram in Utrecht, the Netherlands, during a test drive on the new line to the university, scheduled to open later this year. All the students in the pic (who seem to be on a lunch break) are victims of the overcrowded buses that will finally be replaced. Utrecht already has a sneltram ("rapid tramway") line, entirely on its own ROW and with high platforms, that will be converted to low floor and linked to the new line after it opens.

Get two books: "The bicycle wheel" by Jobst Brandt and "Art of Wheelbuilding" by Gerd Sharaner. Read back-to-back and try not to cringe at the language used.

Then all it takes is practice. I've built about 40 rideable wheels so far and only now I think I am good at it.
Any beginner stand recs? Yes I know you can get away with just using a fork and zip ties, but I want something a little more sturdy and precise, and that allows to check for round true

The chad cassette hub.
Gearhubs and dynos like OPs seem to go together. Weight, efficiency, and cost are important, but not the only factors. If you want a practical vehicle that just works, both those hubs are really nice. I have a Alfine eight speed and a SP dyno, both have been some of the most reliable bike parts I’ve ever owned.

>My sympathies

I'm going to push hard for my shop to drop Cannondale. Holy shit are their bikes terrible to work on...
It's a great option for sure and the one that I've had the most luck with, but it's not always a sure thing. I think T47 is a great option for pretty much all cranks on the market and will hopefully catch on more. Looks like even Trek is on board and changing some bikes from bb86 to T47. Hopefully they'll get rid of fucking bb90 ASAP.

Why do you say that? Do you have other issues other than the BBs?

I do. At first glance stating that China is 4x the size of the US may seem retarded, but using even the slightest bit of logic would give you the conclusion that he's talking about population sizes, which in turn would mean that his argument makes sense.
It wouldn't make sense at all bring up sheer land area because then you'd see most of the liveleak shit coming out of Russia (a close second) rather than China.

CX-Rays weigh 4.41g a spoke while the Aerolites weigh 4.34g a spoke. I personally don't think that little of a difference matters at all, but I wasn't wrong.
>Also wrong
To be fair, I only have anecdotal evidence of the Aerolites being more durable. That means people I know who have built wheels with both and internet forums. If you have any data, please show me and I'll gladly accept I was wrong. If your only argument is Sapim's marketing material, I'll keep believing that the Aerolites are (slightly) superior.

Supposedly the Netherlands is a shining example of what biking culture should be in a country.

But 90% of people and cyclists don't even know what clipless pedals are. All their lives they've just ridden heavy steel 20 kg upright mamabikes with fat tires that top out at 20 km/h. Most people here get mad as fuck at cyclists who use roads when a terrible cobbled cycling path is available,

so did I, and I hated ycling because of it, yet I just did it like everyone else here because everyone does it

Until tonight, when for the first time in my life I put on some actual cycling gear with padded shorts, went on a smooth roadbike, with a helmet (first time in me life), with tiny tires. First I was amazed at how light the bike was (10 kg WTF). Then I felt how clipless pedals works and was even more amazed (why no one told me about them? Not even me parents knew). I just did a 20 km/h lap at 30 km/h average and it felt amazing. I sprinted once to 50 km/h and WOW. This bike is so nippy it is incredible. I was fllying through the streets. now I understand why in foreign countries every one rides more modern bicycles. Now I understand why cobbled paths SUCK.

This made me realize that in the Netherlands we are in fact very behind in cycling. The Dutch bicycle fleet is incredibly outdated and people are completely unaware of the more efficient forms of cycling. My mind is still blown at how fun this is.

>5% more performance
If you don't weigh 350 pounds, going from a 25 pound bike to a 15 pound bike is actually a pretty big deal

Just because you are fat doesn't mean everyone is
That graph shows Mexicans have less than 0.5% more mean weight from burgers, your point is moot.
i ride a sigle speed with 48t at front and my geared bike is 1x with a 53t
Because lighter bikes feel better to ride.
Oh, so it was just poorfag cope all along.
So we went from saying weight has nothing to do with the feeling of snappiness of a bike, all that matters is gearing and tires, now we're backpedaling saying
>m-muh transpo-only board!
Get a grip homegirl, lighter bikes feel snappier

Inb4 LNPshill blames the unions again.

Basically the budget blew out because of expanding the scope of the project, but also some unforeseen issues as well. The construction works of State Library station basically had to be redesigned due to technical challenges, there were adverse geological conditions, and more utility services had to be relocated, 93 utilities instead of the planned 86.

There were also things brought forward in the project timeline into the early works rather than main works phase. These included non-critical "Network enhancement projects" like traffic light timings, road diversions and the like around the main disruptions. The start of tunnelling works was also brought forward so that the project overall is running ahead of schedule - 2024 instead of 2025.

The total cost of the revised, larger early works phase has therefore cost $150m over budget to a total of $625m, but is currently covered with contingency funds. However as the Auditor-General states, this poses a risk of running out of contingency money in the later stages of the project.

tl;dr there was stuff that had to be unfucked, there was stuff that was done earlier than planned, but at the moment the project is mostly still on track.

Link to the report - part 4 has the info about additional works done: https://www.audit.vic.gov.au/report/melbourne-metro-tunnel-project-phase-1-early-works
Oh wow that’s not too bad, I saw some newspapers shilling that it was a $2billion blowout.
They already price in six figure starting salaries and the most generous conditions of any workplace from the beginning.

Blowouts will be from incompetence not graft. The incompetence comes from using Daniel Andrews union mates favoured companies which offer the biggest kickbacks.

>two weeks since metro opened
>still no real time data

also bump
I don't even know what you're trying to say, that it's not graft but incompetence but it's the unions' fault anyway.


Interesting analysis of the actual facts here. Basically Victoria has some of the highest construction wage costs and one of the most unionised workforces but that also means higher productivity. And when wage growth is at all-time lows and there is more and more construction work being done at the same time of course unions are going to argue for, and get, higher wage increases. But when there are only 3 companies capable of taking on large infrastructure projects that's not favouring a specific company, that's a failure of the "free market" to provide competition in the first place. I still think infrastructure work like this should be nationalised and undertaken by the government itself.

Yes it's expensive, but after decades of nothing being done it's necessary to keep up with population growth because no party wants to reduce immigration when our economy is barely staving off a recession off the back of migration alone. The City Loop went 4x over budget from $125m to $500m but forty years later nobody's arguing it should never have been built.

>A 13-year study of a dozen cities found that protected bike lanes led to a drastic decline in fatalities for all users of the road.

>Cities that build protected lanes for cyclists end up with safer roads for people on bikes and people in cars and on foot, a new study of 12 large metropolises revealed Wednesday.

>Researchers at the University of Colorado Denver and the University of New Mexico discovered cities with protected and separated bike lanes had 44 percent fewer deaths than the average city.

“Protected separated bike facilities was one of our biggest factors associated with lower fatalities and lower injuries for all road users,” study co-author Wesley Marshall, a University of Colorado Denver engineering professor, told Streetsblog. “If you’re going out of your way to make your city safe for a broader range of cyclists … we’re finding that it ends up being a safer city for everyone.”


Tfw my shithole city has no protected bike lanes.

In my opinion bike paths are very safe already.

I have never seen a car going on my bike path.
I have only experienced that cyclists got onto the road while overtaking other bikes and a car comming from behind hat to brake very hard.
But to be honest: These cyclists deserve to die anyway.

For the rest of us: Better bigger bike paths than loosing place for seperators.
This. Most people don't seem to realise that the infrastructure in the Netherlands didn't just happen; there was a conscious decision to change how things were done, and a sustained program to build it. It required changes, over a period of time. It didn't get that way accidentally.

It's not like separators are particularly voluminous, they take 15-20 cm of width max. They may or may not increase actual safety, but they do increase the perception of safety, which is arguably more important if you want to get people to take their bikes.
I'm actuallly getting less sure the more bikes I see on the streets.

Bike traffic is very chaotic, because cyclists don't care about rules. Still: A cyclist not caring about rules is less dangerous than a cager not caring about rules.
I'd totally ride that, I'd just make sure to throw my bike in the road and myself in the river if I fuck up.

What's a good entry level frame to start with for a single gear road/track bike? Only using it for fitness and possibly commuting.

I was looking at the 6KU FIXIE, but $199 when I'm going to remove everything except the wheels and hub seems like a lot, but maybe it's a decent start anyway? Wondering if I can save money with just buying a frame.

Also is 58cm okay for someone who is 6'3"

something chromoly not hiten

sounds like maybe you'd be better off doing a conversion from a nice old road bike with horizontal dropouts if you can find one
Why would you be stripping it? At 199 that is a perfdctly acceptable bicycle and the only plus you are going to get swapping out parts on a limited budget is a few badges.
if you're in the US, bikesdirect sells the mercier kilo tt pro, if you want to be a track cyclist get a dolan pre cursa.
Why do you want a fixed gear? Do you live in some artificially flattened hellscape?
1. Fixed gears are fun even without flat
2. Some places are naturally flat

Can't see any threads specifically about Bikepacking. Anyone done much?
