One thing that always bothered me about airplanes is the energy used to take off. On aircraft carriers, they use a launch device, allowing the airplane to "push off" against the carrier. Compare this to airplanes taking off on lan

My 1700x build for video processing has suffered major instabilities -- app crashes and BSODs -- memory corruption type errors. I went through 4 different types of DDR4 memory until I found some that works, even though it isn't on the

The filter checkboxes are a bit weird, for example elements (such as br and img) which are both self-closing and inline only show up if both self-closing and inline are selected, instead of one or the other. Also there are several elements

To a large extent, my daily driving consists of going to the same 5-10 places. I'd like my car to watch me drive somewhere and then just do that, with minimal improvization. For example, in order to enter my driveway I have to swing

Fair point. You don't measure fuel economy on cars by running them on an oval track with the accelerator pinned.

Oh yes, and nobody cared about the performance aftermarket (basically anything you do is going to violate emissions standards) until Harley started selling bikes already modified for "racing". I dropped 20 lbs off a 330lb bike (an

One megahertz is more than enough. That's enough power to compare like three-thousand integer values per second, which is way more than a human can do. We've got these guys out there, and they've got 3 gigahertz and more!

You me and the author are on the same page. Top speed isn't the issue that the author is complaining about, and it's not the reason to get more power. It's about acceleration and hill climbing. That's why he wants mor

Unless you're assuming an awesome future with net guns fired from pirate drones, downing the Amazon drones and stealing their wares, this is just the same package theft issue that already exists.

Probably about 300-500 watt-hours of power and approximately 20 watt-hours per mile, so 15-25 miles.

My favorite sources of information about e-bikes come from endless-sphere.com, electricbike.com, electricbike-blog.com, and the /r/ebikes subreddit. Also I've obsessively watched almost every video with "BBSHD" in

In my opinion the current generation of mid drives are better than the vast majority of hub-drive motors, whether we're talking about the Bosch or Yamaha or Bafang etc... "Better" is a very slippery word. The Gazelle bikes

A bit more info on the 20wh/mile number that I totally made up. The bike you linked has a 250w motor. Running it at 100% for an hour, if you were able to average 12.5mph for that time, that gives you 20wh/mile. Based on the watt-

$500 worth of batteries, $500 worth of motor, $500 worth of bike, and $2500 worth of R&D/marketing/CEO salary expenses. Batteries have come down in price significantly, just in 2016, I'm sure due to the demand from electr

That bike has a 36v, 8.7ah battery. I have a 52v, 13.5ah battery. Watt-hours is volts times amp-hours, so you're looking at 313wh and I've got 702wh, so more than twice. That bike has 1.75" tires and I've got big 3&quo

The law in my state defines a bicycle as a "device having two or three wheels with fully operable pedals and an electric motor of less than 750 watts (one horsepower), whose maximum speed on a paved level surface, when powered solely b

The power output (watts) is a function of (volts * amps) so if you have a 48v battery, you can output ~15 amps and get 750 watts. The amperage output is controlled by software, and these mid-drives are programmable. When you buy the kit,

250 watts is the legal limit in the EU, whereas most states in the US consider e-bikes providing up to 750 watts of power (about 1hp) as still "bicycles" (meaning no registration, license requirements, insurance, etc). A lot of t

I agree about the top speed, 25mph on a trail is dangerous for everybody involved. I want more than 750w of power, not to go faster, but to get up to speed faster after a stop sign/etc. If we could more quickly accelerate up to the li

You can get a "race face" front sprocket that has alternating thick-thin teeth. This holds the chain more tightly and makes it much more difficult to fall off.

It varies slightly by state, but many places you can have up to 750-1000 watts and up to 20mph unassisted on flat ground and still have a bicycle, meaning no license or insurance requirement. You'll typically pedal close to 20mph on f
