How It Came To Be- The Big-Ass Billet Pulley
Once I decided to run a single stage poly-v belt reduction on the e-bike instead of a two-stage timing belt/chain reduction on the advice of Bob Schneeveis I set about figuring out how I was going to come by a foot diameter rear pulley for the bike, preferably a really sweet one, in line with […]

Finding the E-Bike’s limits
A common question asked in these parts when I am describing the power and speed capabilities of the electric bike is “Well, can it scale Marin?”. Marin is an extremely steep street, notoriously and constantly steep- it goes from bottom to the top of the same hill I climbed last time, just in less than […]
An Electric Bike Future? Count Me In
Cars are great, cars are fun- but if you’re looking for ultimate efficiency it’s hard to beat a bicycle. Pedaled or powered a bike will get your butt across town using a tiny fraction of the energy practically any other conveyance would. Meet my latest project: I’ve been working on the parts for this bike […]

A One Wheeler- the Uni-Pogo
Since this project was developed, built, tested and moved on-from all before I wrote anything about it I’ll tell its story: I’ve been interested in the idea of super-compact, minimal urban transportation occasionally over the last few months. The idea of a mass transit “connector”, that’ll get you from your house to the train, then […]
End The Adapter Blues
When you get bad adapters, make bad adapteraide- Wait, that doesn’t work… Never make what you can buy- Hmm, that doesn’t work either… After getting burned by the thesuperkids adapter I decided to bite the bullet and make a better one in the machine shop with tight fitting bores, a D-shaped bore for good torque […]
Don’t Buy The thesuperkids Shaft Adapter
I’m working on putting together an electric bike using a surplus Kollmorgen “Hi-Kol” BLDC motor- more on that later. I’ve gone back and forth about ways to interface with that stubby short little stepped, D shaped shaft on the Hi-Kol- I had gotten fed up with imagining nasty little systems of bushings and decided it […]

Skateboard Nearing A Good Place
In order to get the Skateboard (Facebreaker) a little less rough I’ve worked on a few things over the last couple weeks. Build process previously documented here and here.
The Electric Mega-Skate-Board AKA “Facebreaker” Rides
If you didn’t see it, take a look at the previous skateboard post for an idea what this is all about-
Grand debut- The Electric Skateboard
I’ve been working on this project for a couple weeks now, but haven’t mentioned it here- let’s start from the beginning. I was inspired by this post on Jalopnik– I’ve long been interested in leaning vehicles that aren’t bikes. I hadn’t considered the “skateboard steering” approach before. The more I thought about it, the less […]
