Extending an E-Bike Range from Good to Wheelie Good
It may not look like it in some parts of the world, but electric vehicles are gaining more and more market share over traditional forms of transportation. The fastest-growing segment …read more Continue reading Extending an E-Bike Range from Good to Wheelie Good
Modified Car Alternator Powers Speedy DIY e-Bike
Your garden variety automotive alternator is ripe for repurposing as is, but with a little modification, it can actually be used as a surprisingly powerful brushless motor. Looking to demonstrate …read more Continue reading Modified Car Alternator Powers Speedy DIY e-Bike
Supercapacitor E-Bike With DIY Motor
Supercapacitor technology often looks like a revolutionary energy storage technology on the surface, but the actual performance numbers can be rather uninspiring. However, for rapid and repeated charge and discharge …read more Continue reading Supercapacitor E-Bike With DIY Motor
eBike Conversion on a Budget Uses Skateboard Motor
[Dave Schneider] has been chasing an electric-bike build for more than 10 years now. When he first started looking into it back in 2009, the cost was prohibitive. But think …read more Continue reading eBike Conversion on a Budget Uses Skateboard Motor
Electric Wheelbarrow Makes Hauling Big Loads Easier
Gardening involves a depressing amount of physical activity: haul this over here, dump it there and then cover it with this. Things like wheelbarrows are still damn hard work, especially for people like who are somewhat physically compromised. That’s why we love this build from [Karl Gesslein]. He usually makes electronic bikes, adding motors to bicycles to roam the streets faster. But this time he applied his expertise to a wheelbarrow. He added a 3000W motor to the wheelbarrow, which drives the front wheel when triggered by the accelerator on the handle.
The project is a bit more sophisticated than …read more

Regenerative Braking Charges Your Phone
Way back when, if you wanted lights on your bike, you’d head off to the local bicycle store and purchase yourself a bottle dynamo. This would consist of a magneto that was attached to a bracket on the back of the bike and would rotate by rubbing against the rear tire, generating power for the lights. These fell out of favor over the years as batteries got better and cheaper and people grew tired of the increased drag and maintenance required. Despite this, the idea of generating power onboard a bicycle has never really gone away, and [Javier] has decided …read more
An E-Bike Battery Pack Without Spot Welding
In somewhat of a departure from their normal fare of heavy metal mods, [Make It Extreme] is working on a battery pack for an e-bike that has some interesting design features.
The guts of the pack are pretty much what you’d expect – recovered 18650 lithium-ion cells. They don’t go into details, but we assume the 52 cells were tested and any duds rejected. The arrangement is 13S4P, and the cells are held in place with laser-cut acrylic frames. Rather than spot weld the terminals, [Make It Extreme] used a series of strategically positioned slots to make contacts from folded …read more

[GreatScott] Tests His DIY Battery Pack On His E-Bike
[GreatScott] has now joined the ranks of Electric Bike users. Or has he? We previously covered how he made his own lithium-ion battery pack to see if doing so would be cheaper than buying a commercially made one. But while it powered his E-bike conversion kit on his benchtop, turning the motor while the wheel was mounted in a vice, that’s no substitution for a real-world test with him on a bike on the road.
Since then he’s designed and 3D printed an enclosure for his DIY battery pack and mounted it on his bike along with most of the …read more

Hoverboard Reborn For Electric Rollerblading
Rollerblading is fun, but who needs all that pesky exercise? Wouldn’t strapping on the blades be so much more tempting if you had an electric pusher motor to propel you along your way?
We have to admit that we raised a wary eyebrow as we first watched [MakerMan]’s video below. We thought it was going to be just another hoverboard hack at first, but as we watched, there were some pretty impressive fabrication skills on display. Yes, the project does start with tearing into a defunct hoverboard for parts, primarily one wheel motor and the battery pack. But after that, …read more
