Re: HumanCar Human-Electric Hybrid Car

like to see them get up a 20 % grade in that thing. They claim 60 MPH speed is possible, which is not going to happen unless you have the gold medal olympic rowing team on a slight downhill.

It is a fun looking experiment nonetheless. I wish they would just cool it on the ridiculous claims.

Re: Zenn gearing up for EEStor-powered car

The potential military uses of their technology in submarines, etc. is where most of the stuff will go if they actually bring it to fruition. That is why Lockheed Martin already dumped millions into the company and has exclusive rights to military uses. In one way, its typical that the best technolo...

19 new 100 mile range electric cars announced

http://www.time.com/time/business/artic ... ml?cnn=yes

Looks like high gas prices may have brought the full electric car back from the dead, at least in Europe. Wonder if we'll see any of them here in the US though.

Re: who killed the electric car

current gas prices may just end up raising it back from the dead. Nissan is working on one, and I have read about others in the works besides the Volt. If gas was this expensive a decade ago, we may have tens of thousands of electric cars on the road right now instead of the gas guzzlers the America...

Re: CUT OUT ON POWER cyclone 650watt lifepo 36v 20ah new

LIFEPO4 batteries won't catch on fire, even if they are overcharged. You can damage the cells though if they take too much charge-they puff up and smell REALLY bad. This is assuming there isn't a problem with your pack: I have had a few friends with different brands of LIFEPO4 batteries have an issu...

Re: EEStor Rides Again, This Time on a Bike!

I am actually glad for once the military has great interest in the EEstor technology, because it may mean they actually bring it to market if the end product does get finalized and tested and works as the theory describes. Otherwise, history is full of EEstor examples that got bought out and shelved...

You can find seatpost shocks in any size, even 25.4mm (1 inch). It will have the size on the bottom of your stock seatpost. You have to search hard, but you can also still find a good basic front suspension fork in 1 inch threaded size, which is what your bike probably has. I just got one for a frie...

Re: The cost of an EV conversion

Both Thunderstruck motors and Doug at EV tech have 100AH affordable very high quality LIFEPO4 batteries ( not Thunderpower) that have been working very well for them. They don't have them listed at their web sites-you have to call them. I priced an 84 volt system 100AH and I think it was about $4400...

Re: The cost of an EV conversion

If you convert a small light weight car, the costs go down significantly. weight is a huge obstacle to performance. A fellow in Europe converted a Fiat 500 and is getting 60 MPH and over 60 mile range from a 72V 100AH lithium battery and old DC motor. I know a source for 100AH LIFEPO4 batteries wher...

You'll end up needing two electric bikes anyway, otherwise, how can anyone but Lance Armstrong go for a ride with you?

Re: 203MM Avid BB7 on sale $39.99

I got those brakes from them and they are very strong-stopping power is noticeably better than with the 160mm rotor. Took about 50 miles to bed in fully, but now they stop on a dime with terrific modualtion. You need to have a strong fork to run those on the front, as they generate a lot of force on...

Re: LiFeP04 8AH vs Lithium Polymer 10AH

whose batteries? Not all LIPo and LIFEPO4 batteries are the same, so it is hard to compare two unknown brands. In general, the LIPo have a bit higher output and are smaller and lighter, but do not have the life span of the LIFEPO4 batteries. The LIPo also are more prone to self destructing under bad...

Re: Motobecan 08 Fantom, cyclone 650watts and A123

The BMC's actually run a 7 speed freewheel. Your 9 speed deraileur will work with the 7 speed freewheel. but you have to adjust the limit screws. The rear shifter can be replaced with a 7 speed if you want to, but it will work as fine too, and of course with 2 less speeds. I think in the long run yo...

Re: Have you ever hated your ebike?

At first when I built my 2 e-bikes, I wanted more power, so I wasn't totally happy with them. Then I crashed a bike at only 18MPH and got a first hand experience of the violent power of kinetic energy! I am glad I wasn't going 28MPh when I went down. Two months later, I am still not 100% back to nor...

My one bike will do 43 KPH, the other 35 KPH. My 35KPH is a good mountain bike with quality components and is used mostly on dirt. I seldom go full speed on the dirt with it though, because of traction in the corners. The other bike is a folding mountain bike with 20 inch wheels run at 60 volts on a...

Re: Dual Geared Hubs vs. Nemesis Hill (25% grade)

Sounds like what you are looking for is more of an electric motorcycle. I have heard good things about the hill climbing ability of the one in the link below. They claim it can do a 30% grade. It uses a 6 phase brushless motor rated conservatively at 3000 watts. http://www.rmartinbikes.com./evd-elec...
