[Nick Thatcher] has built several iterations of a homebrew Segway, and the latest version is very impressive. When developing the project he figured there was just no way the thing would ever work, which led to its name, the No-way.
After the break you can catch a video of [Nick’s] test-ride. Looks like the two-wheeler is ready for daily use. You can just make out a red kill-switch on the right side of the polycarbonate body. This lets you disconnect the power if things get out of hand, or just when you’re done riding it. But there is also a dead-man’s switch which we believe uses two sensors where your feet go on the enclosure’s top surface. The handle has some indicator lights built into it, as well as buttons under each thumb which are used for steering. Control circuitry includes an Arduino UNO which reads a gyroscope/accelerometer sensor board from SparkFun. Two 7.2 Ah batteries provide 24V for the pair of electric scooter motors that turn the wheel-barrow wheels.
We love looking at these Segway clone project. So if you’re working on one of your own don’t forget to document your progress!

[Knife141] lets this monkey push him around all day long. It’s a whimsical touch for his scratch-built electric scooter. He started the build without a set of plans, cutting angle iron and clamping it together until the frame looked about right. Once the welding was done, he began adding all the parts to make it functional. There are front and rear brakes, operated by a lever on the handlebars. The rear wheel has a sprocket bolted to it, along with some spacers to give the chain adequate clearance.
Inside the saddle enclosure you’ll find a set of three lead-acid batteries. These are 12 volt 10 amp models that provide 36 volts of juice to the electric motor. The only thing we know about the electronics is that both the motor and the controller were purchased at a surplus store.
The sock monkey that pushes him around is sort of an afterthought. But since it’s just a couple of wheels with the feet attached, this might make a fun project for the kids to add to a bike.
Someone let [Tane] play around with welding equipment and bicycle parts and look what happened! He built a diminutive velocipede. Now that’s just a term for a human-powered land vehicle, but the term fits a bit better as this is missing most of the stuff you’d expect to see on a bicycle.
He started with a mountain bike and a kick scooter, then went to work on both with a hack saw. A bit of welding and angle grinding left him with what you see above. It’s still steerable, but missing are the cranks, chain, and brakes. That’s okay though, the bike is low enough for your legs to reach the ground – you start it up and come to a stop Fred-Flintstone-Style.
[Tane] originally meant to add electric propulsion but didn’t quite get around to it. There’s always the option to add a hub motor to the rear wheel if he has the time and motivation.
We believe that some of the best things in life are built from half-assed ideas and held together with duct tape. Take this fan-powered Razor scooter [Charles Guan] built, for example – it’s chock full of both.
Having built a ducted fan-powered shopping cart in the past [Charles] is no stranger to ridiculous ideas. After a friend sent him a mockup of a fan powered scooter, he felt that he couldn’t “…take such an absurd image not seriously.”
Determined to make his fan-powered dreams a reality, he hunted around for Razor scooter parts, and managed to scavenge just about everything he needed. Parts of three scooters were welded together, forming the wide-stanced trike you see in the picture above. He mounted a fan and some battery packs onto the scooter, both similar to those found on his Fankart. Once everything was in place, he hit the streets.
As you can see in the video below, the Fanscooter looks as fun as it is loud. [Charles] says they have hit a top speed of about 10 mph thus far, but they should be able to blow past that once they balance the blades and have a
victim tester willing to suspend his babymakers over the fan duct. Keep your eyes on his site, we’re sure to see some tweaks and improvements over the coming weeks.

Scooter fans should start sharpening their chisels if they want to undertake this project. This Vespa is the work of a master carpenter and a lot of time. Through the build log photos you can see that it all started with a frame made by bending and laminating wood layers together. Veneer adds the stylish stripe and a lot of carving and turning brings the curves associated with the classic scooters. Even the hand grips, brake handles, and saddle are made out of wood. There’s springs for some shock absorption but we’d bet you don’t want to ride this for too long, or park it outside. Now it just needs an electric motor retrofit.
This scooter has been fitted with a three-phase induction motor. It reminds us of the sound effects from vehicles in the Jetsons. Right now they’re using lead-acid batteries and get about 15 miles of range from one charge. Once they switch over to lithium polymer they calculate the range will be closer to 45 miles due to the reduced weight and increased capacity. Not bad for $600 in parts, and we’d bet it’s both faster and more stable than the one-wheeled-wonder we saw last week.
[Kurt’s] scooter computer started off as a way to use a couple of LEDs to show the battery charge on his hog. It was based on a Arduino and used a voltage divider to judge how much juice was left. But then he ran across a touch-screen OLED shield for the Arduino and the project started to take off. Now he’s got battery, temperature, real-time clock, and GPS running through the slick-looking display. It may not be a full-blown motorcycle but it gives the computer interfaces we’ve seen for other bikes a run for their money.
