    box for ping battery ?

    You guys have seen this setup before, probably, but my solution holds two 15ah 48v pings on front axle extenders, actually they are titanium buddy pegs made for a BMX. Actually, the front axle came from a BMX also. The extra diameter provides a sturdy mount. The weight is about 16lbs on...

    Over 33,000 buyers signed up for GM electric car

    Yea, that fabric frame covering is a great idea. I've thought about using a sand rail frame, essentially a "glider", and then using fabric to mold over the frame bars. I think it might look cool, nice and angular. My reason for doing it would be because I'm not worth spit when it comes...

    How Fast is your Ebike versus How Fast do you want it?

    50KPH on the flat... and thats fast enough for me on a bicycle. Brakes are the limiting factor, for me at least. BTW, no one has mentioned the time it takes to get to top speed. That's important also. I'd love to build a 70mph motorcycle, but don't have the mulla to spend...

    Mounting your battery, Center of Gravity.

    As I stated in my first post on this subject... the front battery box arrangement has some distinct advantages and some real disadvantages. The advantages are a much lower center of gravity overall, and a perfect weight distribution front to back, since my rear motor weighs 30lbs and...

    Mounting your battery, Center of Gravity.

    I'll admit that my biggest concern when I started my battery mounting project was clearance... 1. Clearance between the front spokes and the battery boxes... and 2. Clearance between the battery boxes and the ground while turning. It turns out that careful selection of the right...

    Mounting your battery, Center of Gravity.

    I posted this on another thread, but you might enjoy looking at my "ugly" but (what IMO is a) very effective solution to the battery mounting "center of gravity" problem... I have one fairly close photo of my battery box assembly. Its really very simple. I needed a stonger front axle, so I...

    Just another newbie Crystalyte 408

    I'm running a CLyte Phoenix Cruiser... commuting 20 miles RT to work, with no re-charging at work. I'm using Ping Lifepo4s, two 48v 15ah units slung low on either side of the front axle, wired in parallel, using a big Shotsky. I make my run pretty much flat out, with much up and down...

    Hub battery

    My first e-bike was a Wavecrest 750X, and I really like the way it handled. The weight distribution was just about perfect. However, the bike was underpowered, and lacked any kind of range out of the front hub battery. So, I swapped out all the Wavecrest components, everything except the...

    Watts from Solar Thermal

    Yes, there is a way to do seal the motor... here is a link to a picture... about half way down the page there is a photo of a unit that has round endplates for enclosure of the entire engine in a tube. http://www.greensteamengine.com/ However, the extremely low boiling point of R134a...

    Watts from Solar Thermal

    This subject has been moved from the 55MPH thread... I've discovered that the process I'm trying to base my project on is called the Organic Rankin Cycle. I've read about the Rankin Cycle before, but not the Organic flavor. The more I study this idea the more facinated (and...

    55mph Club

    Commercially available solar thermal panels advertise that they can deliver 37,000 BTUs per day from a panel measuring 38 sq ft. Convert to watts 1 BTU = .293 watts = 3,262 watts per day for the one panel. I'd expect some hefty losses from transport and mechanical conversion... a...

    55mph Club

    That is true, the evacuated tubes are superior performers, especially in northern lattitudes. However, I live at about the 25 degree line, in SoCal. So, that means I should be able to avoid the heavy expense of a $700 panel, and go with a flat panel heat collector. Using a jig design I...

    55mph Club

    I made a decision to move ahead on this project, strictly as a prototype. I purchased the plans and the rudimentary kit for a two cylinder flexrod steam engine. Most of the engine parts I can purchase off the shelf at Home Depot, or make in my shop. I've obtained plans for making my...

    55mph Club

    As long as I'm "burning" the electrons I've harvested from my private property, and not burning any fossil fuel, I refuse to feel very guilty about any speed I can muster above 33 MPH. Right, now, I can't get above that, so the issue is moot, for now :D But, with a bit of luck, some hard...

    Lowdown Front Power

    You're absolutely right about Southern California. The weather is as perfect as can be. The infrastructure, lifestyle, amount of $ left after paying your mortgage - miserable! I've been in this long running argument with my blonde California wife that amounts to "Let's sell this damn...

    Lowdown Front Power

    What I'd really like to scoop up is a charge for my batteries! I see two slightly raised linear contacts running along each side of the bike lane... I push a small lever forward and two spring loaded contacts extend down from the bottom of the battery boxes and into contact with the two...

    Lowdown Front Power

    I’ve used some of these beautiful spring months tinkering in the shop. I was always unhappy with having to abandon the front hub battery design that came from Wavecrest. I thought it was a very elegant solution for appearance, balance, handling, etc. There was much else about the...

    Duct Tape E-Bay Lifepo4s???

    The winning bid for the 48v 15ah battery on Anna's site was $460. There were no other bidders. Since I can't get a response from Anna, I don't suppose a winning price matters. At this point, I can just simply state what I need. I know that Bob is selling LifeBatts, but my impression has...

    Duct Tape E-Bay Lifepo4s???

    Anyone completed any business with anna just recently? I just won a bid on a 48v 15ah duct taper. I get the afore-mentioned response, "sorry, can't take your PayPal payment rght now". Also, no replies to any e-mails, and I've sent her four over the last several days. Anyone else had any...

    controllers

    I'm using this same 4840 controller, and I have some concerns... I'm pushing about 60v (actually 58.9 from fully charged lipoly), and I'm concerned about controller failure due to the high starting voltage. Is there a better controller selection for me that will retire this concern? My...

    Throttle wiring issue Clyte and BMC

    I worked this weekend on my two ebikes... no joy on either so far. Son's bike.. On an attempted matching of a 48v 25amp Clyte controller to a BMC motor and throttle. Got it all wired up except the throttle. The problem there is weird wire colors, no logical way to match them up...

    Crystalyte 35a controllers

    "the 48v will work up to 55v and the 72v unit will work up to 100v" You're pretty sure about that 55v limit, Bob? I've put about 800 miles on my rig powered by a 48v 20ah lipoly, that charges up to 58.9v. The 4835 controller was pushing a Clyte Phoenix Cruiser motor. I think the...
