I tend to be extremely wary of most Kickstarter e-bike projects, and over the last several years there has been a lot of them that have come and gone. One project that has got me pretty excited is the new GeoOrbital wheel that showed up on Kickstarter 2 days ago and already has over $200,000 in…
I have yet to do an article on a BBSxx display because frankly I’ve never been moved to. I did a short article that describes the differences between the many different kinds of displays here, which has been one of the more popular articles on this blog. I’m quite certain that Bafang does not actually…
This article has been a long time coming, but first a little history. My wife and I have 2 houses, hers is 1.2 miles from the road up a 900 ft hill and has an off-grid solar system. She is also Chemically Sensitive so we don’t really have anything that runs with gasoline except our…
So you wanna buy a battery pack but you’re not sure which one to get and you are a dirty rotten cheapskate to boot. There are so many new choices on the market of batteries that completely blow away the batteries of yesteryear that before you plunk down your hardly earned dough you should have…
If I had a cool given name like Ivars I’d probably make sure everyone called me by it, while they followed me into battle to do my bidding. Maybe I’d use ‘Storm’ as my super-hero alias on the weekends while fighting crime, but Ivars is such an awesome name I’d want all my mortal enemies to…
Several years ago a small experimental device appeared on Endless Sphere from a Czech company called Gearsensor who were trying to perfect a new function for mid drive ebikes.

One of the more common questions I get asked is whether people should buy a 48v or 52v battery to drive their ebike mid drive kit. How much power you use on your builds is a choice everyone has to make for themselves, and many people seem happy with lower voltage while others want as high…
This article has been swimming around in the back of my head for a while now. Since I am over $20,000 into the sport, and since I have spent the better part of my life being a Rock Punker I feel like I am probably the best-qualified person to write it. Most people’s experiences with…
The other day I was riding in the woods in several inches of powder with my BBSHD and remembering all the times last winter where I had to walk back to the car pushing my BBS02 equipped efatbike because something failed. It amazed me that I could not remember a single instance in the last…
In case you’ve been hibernating and missed it, something absolutely phenomenal has been happening with Lithium batteries in the last several years. The performance and weight have been increasing by leaps and bounds driven by the power tool, laptop and electric car industries. The 18650 cell formats have gotten incredibly stable and the energy density…
