    Why do so many people buy e-bikes off ebay?

    It must be 90% of the ebikes are bought off ebay. And they always think they are getting a great deal. Everytime I see someone who bought one of those I just cringe. Is anyone here pro-ebay ebikes? Is everyone against buying on ebay?

    Zippy 3s 8400 mah lifepo4 for college kid

    I was reading over on bikeforums.net I was thinking that if he was good enough with crimping, he could put 4 of these together for a good battery pack that is still safe. http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=14073 He has an amped kit but he wants to use it in...

    If it rains on my batteries, will is short them out

    Will it short out my Thundersky cells with the terminals being right there on top? Maybe I should get a waterproof bag to carry in case it rains. I've been fortunate to not have been in the rain but I really want to ride more often and I might get caught in the rain sometime. All that is...

    Best thing about an e-bike

    You can ride on a 90 degree day and not sweat. E-bike makes a 90 degree, an 80 degree day. By the way, my cells are doing just fine.

    The best value uninterruptible power supply for computer?

    I got a power problem over here and the power company says they won't fix it so I need a UPS that will basically give me seamless power supply. My parents have one but it sucks so I need one that's a little better. I read that there are 3 versions: standby, line-interactive, and online. I...

    One Lifepo4 cell that won't hold surface charge

    Okay to put a controller inside a battery box?

    I'm trying to help someone install his controller. He wants to know if he can put the controller inside the battery box. If the controller touches the lifepo4 batteries, could the heat from the controller damage the batteries? I think his battery box is kind of small so I assume it would be...

    I saw one of those big 50cc scooters riding on the sidewalk

    Saw a 50cc scooter riding on the sidewalk downtown yesterday. It made me laugh. I don't know if he was scared of taking it on the road or what.

    Which is more reliable: 50 cc moped or an electric bike?

    Which do you think would break down less? A median priced moped or a top-of-the-line DIY electric bike? The electric bike has lifepo4 batteries.

    Charging lifepo4 and then immediately riding

    Is there any problem with charging the lifepo4 and then immediately riding it with very little time in between? I waited about 10 minutes between charging and riding. The batteries felt slightly warm but not hot at all after I rode for a few miles. I just felt them after about 40 minutes...

    What a blast. I noticed that if I pedaled and floored the throttle, I could out-accelerate most of the cars. I was actually beating cars to the next stoplight. I would floor the throttle then pedal really fast, people riding along side me in cars did a double take. hahaha. This was just...

    I'm considering buying a light ( a very bright light) for my bike and riding at night here in my city. Maybe carrying a metal pipe in my bag for potential problems. I have this 25 " metal pipe and I could just put in my bag. I wonder if it's legal to carry that. Or maybe I could carry a...

    Smaller wheel diameter can give you up to 8 miles more range

    I was using Swbluto's ebike calculator and fooling around with variables. Did you guys know that the difference between a 20" rim and a 26" rim is like 8 miles of range. It says the 20" rim can give you 8 miles more range. That's incredible. It's a couple mph slower but has more range...

    Is there a market for cobra tubes? let your voice be heard

    If these cobra tubes come out in a 26 inch version, and they are $20 or less, I'm planning on buying one as a part of my survival kit when I'm 5 to 10 miles out and I get a flat. I don't want to be sitting on the side of the road for an hour fixing my bike. If you know me, I don't buy many...
