Electric Bike From The Ground Up

Posted on by

Electric vehicles are getting more traction these days, but this trend is rolling towards us in more ways than just passenger vehicles. More and more bikes are being electrified too, since the cost of batteries has come down and people realize that they can get around town easily without having to pay the exorbitant price to own, fuel, and maintain a car. Of course there are turnkey ebikes, but those don’t interest us much around here. This ebike from [Andy] is a master class in how to build your own ebike.

Due to some health issues, [Andy] needed a little …read more

Row Your Bike To China

Posted on by

If you’re a fan of endurance racing motor vehicles, there’s one that puts the 24 Hours of Le Mans, the Dakar Rally, and the Baja 1000 to shame, and the race doesn’t even involve cars. Indeed, the vehicles used for this massive trek from France to China are electric bicycles, powered only by solar panels. This is the epic Sun Trip endurance race, and one of its competitors built a unique tandem bike that is powered both by pedaling, rowing, and the solar panels.

The tandem bike is interesting on its own since the atypical design uses a back-to-back layout …read more

Pavement Projection Provides Better Bicycle Visibility at Night

Posted on by

Few would question the health benefits of ditching the car in favor of a bicycle ride to work — it’s good for the body, and it can be a refreshing relief from rat race commuting. But it’s not without its perils, especially when one works late and returns after dark. Most car versus bicycle accidents occur in the early evening, and most are attributed to drivers just not seeing cyclists in the waning light of day.

To decrease his odds of becoming a statistics and increase his time on two wheels, [Dave Schneider] decided to build a better bike light. …read more

Cheap and Easy Helmet Lights for the Kids

Posted on by

Bikes are a great way to get around and get exercise at the same time, and are widely popular with human children due to the fact that they’re generally not allowed to drive. However, riding on or next to the road can be dangerous, particularly at night, when even adults on bikes are hard to see. It’s far worse for the youngest children, who can be incredibly small and difficult to spot. [Patrick]’s children enjoy riding, but it can get a little sketchy at night, so he developed a solution.

The project relies on cheap, commonly available LED strip lights. …read more

3D Printed Skateboard Mount for Bikes

Posted on by

[Matt Obal] had a problem. The local skatepark was too far to skateboard, but close enough to bike. Carrying a skateboard on a bicycle is a rather awkward (and unsafe) maneuver. [Matt’s] answer to the problem is Truck Stop, a bicycle mounted skateboard carrier he developed and is manufacturing himself.

[Matt’s] work on Truck Stop began about a year ago, with his purchase of a 3D printer. He designed a seat back mounted device that secures the skateboard by wedging between the truck and the board itself. The design is printed in PLA and is hollow. Truck Stop’s strength comes …read more

Gamify Your Workout with the Wearable Console Controller

Posted on by

‘Tis soon to be the season when resolutions falter and exercise equipment purchased with the best of intentions is cast aside in frustration. But with a little motivation, like making your exercise machine a game console controller, you can maximize your exercise gear investment and get in some guilt-free gaming to boot.

Honestly, there is no better motivation for keeping up with exercise than taking classes, but not many people have the discipline — or the pocketbook — to keep going to the gym for the long haul. With this in mind, [Jason] looked for a way to control PS4  …read more

Instrument Packed Pedal Keeps Track of Cyclist’s Power

Posted on by

Exactly how much work is required to pedal a bike? There are plenty of ways to measure the power generated by a cyclist, but a lot of them such as heavily instrumented bottom brackets and crank arms, can be far too expensive for casual use. But for $30 in parts you can build this power-measuring bike pedal. and find out just how hard you’re stoking.

Of course it’s not just the parts but knowing what to do with them, and [rabbitcreek] has put a lot of thought and engineering into this power pedal. The main business of measuring the force …read more

Hackaday Prize Entry: Bellcycles are Open-Source, Compact, and Unique

Posted on by

What do we want in a bicycle? It should be able to be constructed at home, even if your home is a New York apartment. It should be Open Source so our friends can make their own. It should be compact so it won’t clutter up our little apartments. It should be unique instead of another me-too. [Alex Bell], of Bellcycles, is showing off his bicycle on hackaday.io and it fills all the requirements.

The unusual shape drastically reduces the size, turning radius, and storage footprint from a traditional bicycle. It shares the large front wheel design of the penny …read more

A Jet Engine On A Bike. What’s The Worst That Could Happen?

Posted on by

On today’s edition of ‘don’t try this at home,’ we’re transported to Russia to see [Igor Negoda]’s working jet bicycle.

This standard mountain bike comes equipped with a jet engine capable of 18kg of thrust, fixed to the frame under the seat with an adjustable bracket to change it’s angle as needed. A cell phone is zip-tied to the frame and acts as a speedometer — if it works, it’s not stupid — and an engine controller displays thrust, rpm and temperature.  A LiPo battery is the engine’s power source with a separate, smaller battery for the electronics. The bike …read more
