Pedal Far With A Solar Powered Tricycle

Posted on by

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

Unicycle Given a Hand Crafted Gear Box

Posted on by

Being able to coast on a bicycle is a feature that is often taken for granted. The use of a freewheel was an improvement made early in the bicycle’s history, for obvious reasons. This also unlocked the ability to build bikes with multiple gears, allowing higher speeds to be easily reached. On a unicycle, however, there’s no chain and the pedals are permanently fixed to the wheel’s axle, meaning that there is (usually) no freewheel and no gearing. [johnybondo] wanted to get some more speed out of his unicycle, though, and realized he could do this with his own homemade …read more

DIY Arc Light Makes An Unnecessarily Powerful Bicycle Headlight

Posted on by

Remember when tricking out a bike with a headlight meant clamping a big, chrome, bullet-shaped light to your handlebar and bolting a small generator to your front fork? Turning on the headlight meant flipping the generator into contact with the front wheel, powering the incandescent bulb for the few feet it took for the drag thus introduced to grind you to a halt. This ridiculous arc-lamp bicycle headlight is not that. Not by a long shot.

We’re used to seeing [Alex] doing all manner of improbable, and sometimes impossible, things on his popular KREOSAN YouTube channel. And we’re also used …read more

Can A Motorized Bicycle Run On Trees?

Posted on by

Some of the earliest automobiles weren’t powered by refined petrochemicals, but instead wood gas. This wood gas is produced by burning wood or charcoal, capturing the fumes given off, and burning those fumes again. During World War II, nearly every European country was under gasoline rations, and tens of thousands of automobiles would be converted to run on wood gas before the war’s end.

In the century or so since the first car rolled on wood gas, and after hundreds of books and studies were published on the manufacturing and development of wood gas generators and conversion of internal combustion …read more

Cheating the Perfect Wheelie With Sensors And Servos

Posted on by

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

Power Steering Pump Repurposed for Great Speed

Posted on by

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

More Suspension Than Necessary

Posted on by

The triangular frame of a traditional mountain bike needs to be the most rigid structure, and a triangle can be a very sturdy shape. So [Colin Furze] throws a spanner in the works, or, in this case, a bunch of springs. The video is below the break, but please try to imagine you are at a party, eyeballing some delicious salsa, yet instead of a tortilla chip, someone hands you a slab of gelatin dessert. The bike is kind of like that.

Anyone who has purchased springs knows there are a lot of options and terminology, such as Newton meters …read more

The Apocalypse Bicycle

Posted on by

It seems to be a perennial among humans, the tendency among some to expect the End Times. Whether it was mediaeval Europeans who prepared for a Biblical Armageddon at the first sight of an astronomical phenomenon, 19th-century religious sects busy expecting a Noah’s flood, cold-war survivalists with bunkers under the lawn, or modern-day preppers buying survival gear, we have a weakness for thinking that Time’s Up even when history shows us repeatedly that it isn’t. Popular culture has even told us that the post-apocalyptic world will be kinda cool, with Mad Max-style rusty-looking jacked-up muscle cars and Tina …read more

Animated Bluetooth Bike Turn Signals

Posted on by

Tired of risking his life every time he had to signal a turn using his hands while riding his bicycle in rainy Vancouver, [Simon Wong] decided he needed something a bit higher tech. But rather than buy something off the shelf, he decided to make it into his first serious Arduino project. Given the final results and the laundry list of features, we’d say he really knocked this one out of the park. If this is him getting started, we’re very keen to see where he goes from here.

So what makes these turn signals so special? Well for one, …read more
