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 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 Iron Nano-Phosphate Lithium Polymer batteries mounted between hand finished Brazilian Rosewood boards. These batteries are rated at 150 amps continuous and will supply one horsepower for an hour. All my bikes feature an abundance of custom machined parts, well thought out instrumentation and form follows function design.

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.

If a penny gives 3.33 miles, a dollar will give 333 miles.

At $4.00 per gallon and 25 miles per gallon the average car will go 6.25 miles on a dollar of gasoline.

A dollars worth of electricity will push you down the road more than 50 times as far as a dollars worth of gasoline.

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 Motor

The motor is a Conhis unit from China. http://www.conhismotor.com/ProductShow.asp?id=97

I check every motor for shipping damage, continuity, bearing condition and extra solder balls inside the motor.

The motor is rated at 1000 watts, momentary load reads about 1500 watts depending on the state of charge. Straight off the charger with a warm pack the Cycle Analist reads Full load at 51.5 volts, 29.8 amps and 1535 watts. At mid charge the voltage under full load (30 amps) will sag to 49 volts.

 

Operation below 5 amps load will not be very efficient. At 5 amps load the bike is 71% efficient and will travel at about 18 miles per hour. At a little less than 6 amps efficiency is 75% and speed is about 20 MPH, this is the optimum power setting for maximum range. The extra wind resistance encountered at 31 MPH and 10.5 amps in a tuck and 15 amps straight up counters the 3% gain in efficiency reached at a 15 amp draw. Most energy use in practical riding is fed into the maw of the acceleration monster, where it is held in in kinetic storage. If you coast to a stop,that energy gets used by you. If, however you have to use the brakes, the energy is taken from kinetic storage and given to the deceleration monster, he uses it to make heat.

Anything that gets hot is drawing the required energy to make that heat from your battery pack.

The batteries

Range estimates

53.47 miles in 2012

53.81 miles in 2013

50.46 miles, as of July in 2014

These are my best rides.

On a cold day the expected range is cut by about half.

Aggressive riding cuts your range in half.

Aggressive riding on a 50 degree day will get about 15 miles.

Conservative riding on a 90 degree day might go 60 miles.

Heat, to a certian extent is important to battery performance. You are dependant on a chemical reaction to push the electrons that power the bike, the more heat, the more energy. Untill you start to damage the cell.

With these cells, damage starts to happen somewhere over 115 Deg.F

Anything that feels warm on this bike is wasting energy, generally, nothing on the bike is warm. The cells are suspended individualy and are protected both from road shock and overheating. Caution, the cells will get hot if the sun shines on them while the bike is parked. If the bike is moving the cells have plenty of ventalation and are safe from overheating.

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 and a braided connector instead of a bolted battery connection, less physical stress is transmitted between cells.

Also, 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. The rear section of this 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 priveleges 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]

Translation, if the code does not specifically state "Electrically assisted bicycle" It does not apply. This is not a motor vehicle, this is a bicycle.

 

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

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?
