A mid-production image of the headlight on John's trike
The most important guage on any electric vehicle is an analog ammeter. The trike also has a digital ammeter as part of the instrumentation, but the operator needs to see that swinging needle for instant feedback without having to read the numbers.
The headlight makes a great ray gun when detached from the bike.
The inset Josh Mazet marble is illuminated from the bottom of the infinite swirl. The light can be any color and also lights the ammeter.

If Jules Verne designed a bike for Phineas Fogg, it might look something like this. Don't let the funky design fool you, the very best Lithium Polymer batteries mounted between hand finished Brazilian Rosewood boards. These batteries are rated at 150 amps each and will supply one horsepower for an hour. All my bikes feature an abundance of custom machined parts, well thought out and executed instrumentation and an overall style second to none.

I built this bike from design to the last wire tie.

I can build one for you too.

Efficiency, Equivalent Energy Cost

Lets say an average charge gives you 40 miles, that's about what I get.

It takes about 1 Kilowatt-hour to charge the pack, in Eugene, OR, that's 12 cents, as long as the rate holds.

$0.12 / 40 miles = $0.003/mile or 3.33 miles per penny.

Over the summer I had a great time putting 1500 miles on this bike.

$0.003 * 1,500 = $4.50.

To get that 1,500 miles I put 37.5 full charges on the bike. 

37.5 full charges * 12 cents per charge = $4.50.

With $4.50 as a base point price for gasoline, this bike gets 1,500 miles per gallon.

At $4.00 it's 1,333 miles per gallon.

At 6 bucks, like currently in California, it,s an even 2,000 miles per gallon.

Basic Specs

 

  • 1,000 Watt hub motor from Conhis motors
  • 15 Amp-Hour battery pack from Headway Headquarters
  • The frame on my personal bike is that of a late model Schwinn Sting Ray. I have  Super Fat  frames from US Cycles for full size people ( I'm 5'6" and weigh 140 lbs)
  • Range is 30 miles in full crank and go mode. Pedaling off stoplights and up hills will increase range considerably. 
  • Best range is 52.42 miles
  • Speed is 31 miles per hour
  • Weight is 100 pounds
  • Charge time is 3 hours
  • The battery pack takes one kilowatt-hour to charge, in Eugene, OR. that's 12 cents

 

The batteries

The batteries are the latest technology LiFePO4 cells, protected by the best battery management system available from Headway-headquarters.

At 48 volts and 15 amp-hours, this pack will propel the bike up to 53.81 miles.

That's my best distance.

The Headway LiFePO4 40152 cell is one of the few single cells that have a continuous discharge rate of 10C (150 Amps), and maximum pulse up to 17C (255 Amps), all with a very low resistance, high capacity, and screw terminals. Screw terminals make it much easier to connect the cells in series and/or parallel into larger packs. With the screw terminals instead of a welded or soldered tab connection, pack maintenance becomes much easier.

Recommended uses for these cells include; electric bikes, electric motorcycles, electric cars, electric boats, electric golf carts, electric lawn mowers, etc, and also stand-by storage batteries for solar power systems.

Repairs & Maintenance

These bikes are the best I can build with the parts I can scrounge, buy or make.The result is a fairly low maintenance rig.Most maintenance can be performed by any qualified bicycle mechanic.

The electrical maintenance can be performed by someone familiar with electric bikes or any qualified electrician.Primary maintenance will be replacement of the brake pads and the rear tire.

 

Left: Detail shot of a .560" wide dropout I designed for my first bike. The dropout is made of stainless steel with a machine finish. There are 3 mounting bolts about 3 inches apart, one under the stoplight, another about 4 inches higher on the Schwinn dropout and the third goes through the original wheel mounting slot. The new dropout is .315 thick behind the Schwinn dropout. Note the rear edge of the .315 section just visible at the leading edge of the Schwinn dropout. In the rear of this edge the dropout is .560 thick. Plenty wide enough to twist the axle to failure without harm to the bike.

There are no modifications at all to the original Schwinn frame, all components are either Clamp on or bolt to pre-existing holes.

The copper coils around the crankshaft sprocket.

When the rotating assembly was rebuilt, it was out of balance by several Inch*ounces. The copper coils are there for balance.

Notes on Electric Bicycles

Electrically assisted bicycles enjoy a number of privileges and exemptions. This bike pushes the legal parameters of "Electrically assisted bicycle" to every conceivable limit. Your bicycle will be programmed to comply with your state laws when it is delivered.

 

A breakdown of state by state laws can be found here. http://en.wikipedia.org/wiki/Electric_bicycle_laws 

 

Laws specific to Oregon can be found here.

http://www.oregonlaws.org/ors/814.405 

Status of electric assisted bicycle

An electric assisted bicycle shall be considered a bicycle, rather than a motor vehicle, for purposes of the Oregon Vehicle Code, except when otherwise specifically provided by statute. [1997 c.400 §4]

 

Please tell me you live in Florida so I can build you a no holds barred 60MPH road rocket.

News

October 15'th, 2012 was a big day.

I presented a defense before the honorable judge McAlpin here in the great county of Lane, Oregon. I stand accused of speeding(25 in a 20 MPH zone), Improper lane change and not wearing a helmet.

With all the court running around and the day's later errands, I put 52.42 miles on a single charge. Before leaving in the morning I found I had needlessly burned up 1.4 amp-hours by leaving the bike on all night.

Therefore the bike had a 93.33% charge when I left.

Theoretical maximum distance would then be 57.31 miles.

The frame started life as a Schwinn Sting-Ray. Built from 2002 to 2006, the bike had great style going for it but little else. The Sting-Ray was beautiful but too heavy to be commuter friendly. The bike has a special 5 inch wide crankshaft required to get the chain by that fat rear tire. This leaves plenty of space for a battery pack centered between the pedals.

 

At 40 miles per charge and a 12 cent charge cost for one kilowatt-hour, and given that the average vehicle in America gets 25 miles per gallon, your equivalent energy cost is $0.0625 for a gallon of gas.

Every time a charge is used on this vehicle, $5.00 magically jumps into your pocket.

If you commute 100 miles a week (about average) that's 4 gallons.

If you run another 50 miles on errands that require minimal cargo hauling that's another 2 gallons.

6 gallons at $3.50 is $21.

6 charges at 12 cents is $0.72

The savings are $20.28 per week. Like to chop $85 off the monthly fuel budget?
