Extending the chain stays

November 21, 2009

The rear triangle is coming together. The chain stay extensions are stripped of paint and fitted. I wish I had a tube notcher or milling machine. Someday I will. For now I’m using a cutoff wheel, dremel tool, and files. Learning how to notch the tubing to fit exactly is a skill and will take […]

It begins by cutting off the stays

November 20, 2009

No going back now. I’m going to extend the length of the bike and drop the batteries down between the seat post and the rear tire. You can see the approximate placement and size of the battery box in the photo. This will lower the center of gravity and extend the wheel base which should […]

Check Out My New Electric Bike

November 17, 2009

Or maybe I should say: ‘how many old bike frames can you get into a Honda Insight?’. The answer is eight plus other bits and pieces. I’m on a budget so I don’t want to spend a lot of money on tubing and parts right now. I’m going to be making a lot of mistakes […]

Weatherproof Your Motor Controller

November 13, 2009

I don’t know about you but I like to have my gear protected from the weather. Having a more secure installation has its benefits too. I like to ride my bikes all year round so I needed a good solution for keeping my controller safe and sound. For my cargo bike I made the box […]

Want a cargo bike but don’t want to pedal all the weight?

November 9, 2009

This is my heavy hauler which can haul a LOT of weight. It can go mostly on it’s own power but up steep hills and fully loaded, it takes a little pedaling. The bike is a MUNDO and is made in Germany. It was designed for 3rd world countries as an alternative hauling vehicle. It’s […]

Can you see what’s wrong with this electric bike design?

November 6, 2009

The biggest problem is that it’s top heavy and the battery weight is behind the rear axle. The batteries weigh about 35lbs. This makes handling very shaky. Another problem is the wide aluminum beach cruiser bars; they flex too much when trying to move all that weight which makes steering very vague and sloppy. Those […]

Repair bikeE seat frame

October 21, 2009

As was mentioned in a previous post, the seat frame brace is cracked at the base. This was fairly easy to fix. I had to completely remove the seat so that I could braze weld it back together. I didn’t want to spend a lot of time making it pretty in case it cracked again. […]

Quick and dirty (but useful) torch holder

October 17, 2009

I had really big plans for fabricating a holder for my torch. Then I noticed a piece in the scrap pile. If you can’t tell already, it is the end of a bed frame with a notch and a piece of welding rod tacked on to hold the torch in place. It works really well. […]
