Electric bikes, and really all electric vehicles, have one major downside: the weight and cost of batteries. Even with lithium, battery packs for ebikes can easily weigh more than the bike itself and cost almost as much. But having to deal with this shortcoming could be a thing of the …read more
There’s no better way of improving a project than logging data to make informed decisions on future improvements. When it came to [Brian]’s latest project, an electric bike, he wanted to get as much data as he could from the time he turned it on until the time he was …read more
[Tom Stanton] is well-regarded in the maker community, and has put much effort in over the years on a variety of electric vehicle builds. In the process of upgrading his e-bike last year, he ran into some issues with the main drive pulley. Rather than rely on guesswork, he threw …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
[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

[Rasel] likes to make things himself, and his latest project is a homemade electric quad bike. It’s an impressive build, including two 1 kW motors and a tilting turning system that makes it more maneuverable than most quad bikes. It has big, wide tires, a raised battery and longitudinal arms that mean it can climb over obstacles. That all makes it great for off-road use, and it’s just 60 cm (just under 24 inches) wide, which is much smaller than most quad bikes. It also has a top speed of 35 km/h, which would make it somewhat illegal to use …read more
One of the more interesting yet underrated technological advances of the last decade or so is big brushless motors and high-capacity batteries. This has brought us everything from quadcopters to good electric cars, usable cordless power tools, and of course electric bicycles. For his Hackaday Prize project, [marcus] is working on a very powerful electric bicycle controller. It can deliver 1000 Watts, it’s got Bluetooth, and there’s even an Android app for some neat diagnostics.
The specs for this eBike controller are pretty much what you would expect. It’s able to deliver a whole Kilowatt, can use 48 V batteries, …read more

When it comes to bringing an idea to life it’s best to have both a sense of purpose, and an eagerness to apply whatever is on hand in order to get results. YouTube’s favorite Ukrainians [KREOSAN] are chock full of both in their journey to create this incredible DIY e-bike using an angle grinder with a friction interface to the rear wheel, and a horrifying battery pack made of cells salvaged from what the subtitles describe as “defective smartphone charging cases”.
What’s great to see is the methodical approach taken to creating the bike. [KREOSAN] began with an experiment consisting …read more

Over the last few years, powerful brushless motors have become very cheap, batteries have become very powerful, and the world of quadcopters has brought us very capable electronic speed controls. Sounds like the perfect storm for a bunch of electric bike hacks, right? That’s what [bosko] is doing for his Hackaday Prize Entry. He’s building an e-bike with a big motor and an electronic dashboard, because a simple throttle switch would never do.
There are two parts to [bosko]’s bike, with the front brain box consisting of GPS, an OLED display, analog throttle, and a few wireless modules to connect …read more
