From: Greg Davey

Dear Electric Vehicle Enthusiast,

Have you had enough of increasing gas prices and auto insurance rates? Are you sick of wasting a large part of your day stuck in traffic crawling at a snails pace during your commute to and from work?

Are you concerned about global warming and want to do your part to reduce your carbon footprint?

Well you are about to find the answer to all these problems AND put some fun back into your daily commute by learning how to build your own fast, economical electric vehicle.

Maybe you have tried pedaling your bike to work but found it just takes to long and you arrive all sweaty with nowhere to take a shower when you finally do make it there.

Then after a long, hard day at work you just don't have the energy or desire to pedal all the way home again.

Or perhaps you have purchased a prebuilt electric bike or electric scooter but find it extremely underpowered and the batteries run flat before you reach your destination.

Well I am about to change the way you think about electric bikes!

My name is Greg Davey, better know as the "Mad Scientist" by friends and family even though I have no electrical or engineering background. I, like many of you, decided I wanted a better form of transportation.

I wanted to save money on gas and reduce my carbon footprint. Sitting in my car for up to an hour stuck in traffic each day for a drive that should only take 15 minutes was not acceptable anymore.

You may be wondering what makes me an expert in electric bikes. Well back in 2005 I spent several weeks researching electric bikes on the internet and decided to built one using an old mountain bike I had.

I purchased all the parts I needed from a local ebike store and had the bike up and running in a few days.The first time I took it out for a test ride I almost crashed because the bike handled so bad. It was several days before I got used to it.

I eventually managed to ride the bike to work but it handled terrible at speeds over 20MPH.

The brakes all but stopped working when they became wet, the power would turn on and off randomly because of poor connectors and the batteries quickly drained slowing the bike barely getting me home.

I even had to push the bike home several times because something failed.

This bike was very scary to ride because it was so unstable but I used it for over a year until the batteries finally packed it in.

I loved the idea of riding an electric bike to work because it was cost effective and I avoided all the traffic but it needed some dramatic improvements.

I went back to the drawing board and painstakingly researched bicycle geometry, suspension forks, batteries, battery management systems, motors, controllers, and any other parts I would need to build the ultimate electric bike.

Then I started testing different bike parts and electrical components picking the ones that worked the best and assembled them from the ground up building the perfect electric bike.

I now have a 100% electric vehicle that I use as a replacement for my car. Not only do I get to work faster than it used to take me to drive, it only costs me pennies a day to recharge the bike.


The electric bike works so well I decided to sell my car which gave me $13,000 cash in my pocket on top of the $1,200 I saved on car insurance.

The only downside of riding the electric bike, if you can call it that, is the bike is an incredible attention magnet. Everywhere I ride people are constantly stopping me to ask questions about it.

On my very first test ride after building the new bike I pulled over to the side of the road after 15 minutes of riding. A few minutes later a city works vehicle pulled up beside me and came to a screeching stop in the middle of the road.

Two city workers with stunned looks on their faces jumped out and ran over to me. They said I passed them several kilometers back and they just had to find out what I was riding.

They were blown away by the bike and immediatley starting asking questions about it so they could build their own.

After an overwhelming number of similar requests from people who stop and ask me about the bike I decided to document the entire build of this awesome electric bicycle in my brand new ebook called

"How To Build a 50MPH Electric Bike"

You can build the exact same bike at home using this easy to follow step by step manual, even if you have no previous experience. The ebook is a pdf file that can be downloaded in just a few minutes and viewed using the latest version of adobe acrobat which you can download for free.



  My name is Evan Filter, and my Drexel University senior design team and I are designing electric motor assistance systems for Drexel's Human Powered Vehicles.  I read through your "How to Build a 50MPH Electric Bike" document forwarded from Dr. Layton, and your bike is really amazing.  I would love to use your expertise as we go along. Please let me know if you would do us the honor.  Thanks

In this book I have filled over 100 pages with the detailed information you need showing you exactly how to build a fast electric bike even if you are a complete novice and know nothing about bikes or electricity.

Included in the book is more than 150 high quality photographs so you can see how it's done.

I take you by the hand and walk you step by step through the entire build process to ensure you will be riding your bike in no time.

Here is a list of just some of the benefits you get from building an electric bike yourself:

  • Lowest cost electric vehicle -Because you need such a small battery pack compared to an electric car or motorcycle you can afford to buy the latest technology batteries which means they can last up to 10 years before they need replacing.
  • Never wait in traffic again - simply pass all the slow cars by riding on the shoulder or in the bike lane.
  • Ride at the same speed as a car - I will show you the secrets to increasing the power from a standard motor controller so you can ride at speeds over 50MPH and out accelerate most cars from a stop.
  • Choose how far you want to ride - I show you the simple calculations to determine what size battery pack you need to travel a specified distance. My bike has a range of 30 to 50 miles depending how fast I ride before it needs recharged.
  • Save money on insurance and vehicle costs - you won't need to own or insure a car when you have a fast electric bike. No more oil changes or vehicle repairs to worry about.
  • Never buy gas again - simply plug your bike into your charger and recharge it for pennies a day.
  • Never pay for parking again - just lock your bike to the closest bike rack or in a secured bike locker.
  • Reduce your carbon footprint - stop polluting by using an eco-friendly electric vehicle.
  • Ride warm all year long - You will learn how to ride warm and comfortable in temperatures well below freezing by making your own heated jacket (one of the free bonuses you will receive).
  • Ride silently - You may be surprised by the wildlife you see on a bike trail because the animals can't hear you. I have seen coyotes, skunks (don't get to close), owls,deer and even a beaver on the bike trails riding home from work.
  • Experience the EV Grin - this is the huge smile you will have on your face after your first ride on your new electric bike.


"I am very impressed with Greg's eBook, it is remarkably thorough, detailing exactly how to build your own 50mph electric bike step by step. There are illustrations on nearly every page to help you along the way, which is great for those tricky wiring parts! All in all this is a very comprehensive and well-written guide and I would recommend it to anyone looking to build their own fast electric bike. Can't wait to start my own! Thanks Greg!"
