Down-sizing our transportation life style

we must all start building these electric bikes in every town if there is to be any chance of survival. Down-sizing is the only technology that will do the job!

How to buy an electric bike that will last 20 years.

You need to understand why most electric bicycles will not last long. Most electric bicycles are built to sell to people that simply do not understand what is needed, to live with out a car.

Why are Hub motors not as efficient as they claim? Because they are set in a very high gear. Not designed for stop and go driving!

Do I need gears? Not if you have a power system that has a wide enough range of usable “torque”(thrust!)

Where to Start/ A small e Bike Business

I believe that every community should have at least one small garage shop installing motors on cargo bikes. Don't wait for a market to materialize out of a world that does not have a clue what to do. Build the market your self!

Unfortunately people need low cost equipment, that usually means that people will buy cheaply made electric bicycles that will burn-out after a short period of climbing steep hills with cargo.

If you live in a city that has steep hills you need to do a bit of researcher before you waste your money. Try to understand what makes a long lasting electric power system. Direct drive hub motors are a waste of money! They are set in a very high gear that requires much more power to climb those hills.

Most mid drive systems that use your bicycles drive chain and gears are not only illegal but will wear out you chain faster than necessary. Fixed gear systems are by far the best way to mount a motor. But they take more planning and thought to rig them correctly.

Read my blog and think before wasting your time and money. If your budget is too low for a high voltage motor system, think about using a hub-motor rigged as a mid-mounted fixed gear drive with a belt in place of a chain.

Not running that power through the bicycle drive chain will make a huge difference in how long the vehicle lasts. And having the right gear for your worst hill will keep your power system from burning out.

A non-profit small electric vehicle project for Port Townsend

I see a need for small hand made electric vehicles. This can only increase as the awareness of climate change and peak oil improves. Simple bicycles will not do the job.

New factory made electric vehicles would produce about 13 tons of green houses gases for every ton of new vehicle. So I want to build a demonstration model of a vehicle that can haul at least 600 to 800lbs total combined weight up an 8% grade. ('F' street hill)

This could be a cargo trike but it would be easier to build a European style cargo bike for the first project. A small vehicle for two people and a small amount of cargo would weigh about 600-800lbs fully loaded. A small car would weigh far more, and take much more energy to operate.

Most people have no clue how to motorize a minimalist vehicle that is made to handle as little weight as most people haul with their cars. Recently I wrote an article about what it would take:

I have been researching this project for several years now and believe it is possible to build a simple cargo bike with power system for under $5000. I cannot get a grant to build something like this by myself. It should be a community project, then used by the community. People need to see how easy it can be to downsize our transportation needs; there needs to be a new kind of business paradigm.

We need to start a non-profit organization
