really good gas mileage. At around 40-55 mph I can get really good gas milage of around 50-70 mpg, at higher speeds its reduced to around 32-36 mpg.
I usually average around 41 mpg overall. My 4x4 F150 gets only 6 mpg.
JohnPhoenix you should start a thread on your electric bicycle and tell all of us more about it. I think it would be very cool to have an electric
bicycle. Have you ever charged it from solar panels? How far can you go on a charge? and at how fast of speeds? Does the wind affect it? I know
lots of people that are interested in electric bicycles. I also believe that this guy got all of his discoveries from bicycles.
It looks like to me, that the next alterative will be to place these same devices on motorcycles, 3-wheelers and ATVs.
This thread needs a bump. And I've got to tell a little more about my comments above. I criticized this technology as not being too practical but
that's not the end of it. I do think this technology is a necessary step, or a necessary evil if you will. It will help more people get less
dependent on gas ( in a way) but it's really just a band-aid. Electric right now is the best idea for technology that gets our vehicles off petrol.
Yes, hawkiye here has a vehicle that runs off hydrogen gas if I'm not mistaken and I'd like to hear more about that but I understand he has to produce
his own fuel.. is that right? Perhaps hawkiye can tell us more about it and the costs involved.
I think Electric is king because it's proven, practical and cheap if you do it right. The Tesla Motors cars are luxury items and the batteries are
very expensive. Chevy Volts are cheaper but the batteries are just as pricy. The batteries Are the problem. In the video above the hybrid system uses
a Lithium Iron Phosphate battery, commonly called LiFePo4. These batteries are Only made in China because they have one of the largest Lithium
deposits on the planet. These are the most efficient and powerful electric batteries made but since they are not mass produced by very large
companies, they are not cheap. To buy these, you have to find a reputable manufacturer in china and have it shipped to the US ( or anywhere else)
China does not have a lot of regulation and the e-bike community has learned to trust only one manufacturer called Ping Battery. These people make
excellent quality batteries for the price you have to spend. There is talk of new technologies that can extract Lithium from seawater - a much more
cost effective way to obtain Lithium. I believe someone is planning to open a plant that does this in the US. If this takes off then American
companies will be able to produce LiFePo4 batteries cheaply enough so everyone could afford them. I'd like to see this happen and electric cars become
the norm instead of the exception. Only then will we have a chance to get rid of petrol.
As far as my e-bike, it's a mens 26 inch Next brand 10 speed mountain bike from Wal-Mart - cost 100 dollars. I paid 700 for the e-bike kit from
Ampedbikes.com The e-bike kit consists of a 750 watt brushless hub motor comes with a voltage regulator/controller, a throttle and brake set, a
battery pack of 3, 12 volt 12 AH sealed lead acid batteries (total of 36 volts) to which I added a forth for 48 volts. They last about a year, so I
replaced those with a Ping LiFePo4 20 AH that cost about 600 and last about 3 years. It works out to be about the same price in batteries over the
course of 3 years having to replace the SLA batteries once a year but the advantage of the LiFePo4 battery is you know you will have more consistent
power longer and it makes the whole bike much lighter, giving you more range. Volts = speed and the battery AH rating equals range. I get more range
with the LiFePo4.. I'd say a solid 10 miles there and back for a range of 20 miles round trip between charges. Cost pennies to charge and a few hours
time. This is without peddling going 30 miles an hour. As you see, the initial cost is under 1000 dollars.. adding the LifePo4 has me into it for
about 1500. You may want to spend extra money for headlights, turn signals, stop lights and puncture proof tires. Some places require these things.
With the 3 batteries that come with the kit you can't go over 20 miles per hour in the US legally. If you add a 4th battery or go over 36 volts to go
over 20 mph your not supposed to drive it without a license in the city. My experience if your careful, no one will know your going over 20 mph LOL
You'd have to check your local laws.. I don't know where you live.
