Collaborate Disseminate
They say you can’t manage what you can’t measure, and that certainly held true in the case of this bicycle that was used to measure the speed of cars in one Belgian neighborhood. If we understand the translation from Dutch correctly, the police were not enforcing the speed limit despite …read more
If you’re in a relatively urban area and your destination is within a reasonable distance, it’s hard to argue against riding your bike rather than taking a car. It’s a positive for the environment, and great way to exercise and keep active. But some of us, say folks who write …read more
[André Biagioni] is developing an open hardware bicycle navigation device called Aurora that’s so gorgeous it just might be enough to get you pedaling your way to work. This slick frame-mounted device relays information to the user through a circular array of SK6812 RGB LEDs, allowing you to find out …read more
For his entry into the 2019 Hackaday Prize, [Marin Vukosav] is working on an ambitious project to create a small GPS tracking device which utilizes Narrowband IoT (NB-IoT) for long range communications. Rather than using a GSM modem which would suck the batteries dry in short order, NB-IoT can theoretically …read more
Crashing one’s bike is a childhood rite of passage, one that can teach valuable lessons in applied physics. Assuming the kid is properly protected and the crash is fairly tame, scrapes and bruises are exchanged for the wisdom to avoid sand and gravel patches, and how to avoid a ballistic dismount by not applying the front brakes harder than or before the rear brakes.
But for many of us, those lessons were learned long ago using a body far more flexible than the version we’re currently in, and the stakes are higher for a bike ride that includes braking mistakes. …read more

Bikes are a great way to get around. They’re cheap compared to cars and can be faster through city traffic, and you can get some exercise at the same time. The one downside to them is that the storage capacity is often extremely limited. Your choices are various bags strapped to the bike (or yourself), a trailer, or perhaps this bicycle side car made from a beer keg.
Sidecars are traditionally the realm of motorcycles, not bicycles, but this particular bike isn’t without a few tricks. It has an electric motor to help assist the rider when pedaling. With this …read more
Electric vehicles of all types are quickly hitting the market as people realize how inexpensive they can be to operate compared to traditional modes of transportation. From cars and trucks, to smaller vehicles such as bicycles and even electric boats, there’s a lot to be said for simplicity, ease of use, and efficiency. But sometimes we need a little bit more out of our electric vehicles than the obvious benefits they come with. Enter the electric drift trike, an electric vehicle built solely for the enjoyment of high torque electric motors.
This tricycle is built with some serious power behind …read more
More and more electric bikes have been rolling out into the streets lately as people realize how inexpensive and easy they are to ride and use when compared to cars. They can also be pedaled like a normal bike, so it’s still possible to get some exercise with them too. Most have a range somewhere around 10-30 miles depending on battery size, weight, and aerodynamics, but with a few upgrades such as solar panels it’s possible to go much, much further on a charge.
[The Rambling Shepherd] had a tricycle (in the US, generally still considered a bicycle from a …read more
Everyone remembers popping their first wheelie on a bike. It’s an exhilarating moment when you figure out just the right mechanics to get balanced over the rear axle for a few glorious seconds of being the coolest kid on the block. Then gravity takes over, and you either learn how to dismount the bike over the rear wheel, or more likely end up looking at the sky wondering how you got on the ground.
Had only this wheelie cheating device been available way back when, many of us could have avoided that ignominious fate. [Tom Stanton]’s quest for the perfect …read more

Electric bikes are getting a lot of attention lately. Pretty much anyone can buy a kit online and get a perfectly street legal ride with plenty of range. But if you don’t want to take the kit route, and you’d rather take a tack that will get you noticed more around these parts, take some notes from [Jule553648]’s recent build that definitely isn’t using any parts from a kit.
The motor from the build is an electric power steering pump from a junkyard car. This gets mounted on a one-off rear bike rack and drives the rear tire with help …read more
