    Available LiFePo4 Battery Packs

    Hi All, I have been researching pre-built 48V - 20Ah LiFePo4 Battery Packs for quite some time now, to be used on my new e-bike project. One of my criteria was that it needed to be below the pain threshshold of $1000. Here's a table of the LiFePo4 available packs I found (last item in list is...

    thick wire

    Find yourself some cheeseball jumper cables. They are usually quite cheap, flexible, and about the right thickness. -Warren.

    Finally! The Cyclone 500 watt review...

    Hi Pete, If the Cyclone controllers are prone to back EMF, then we should just be able to add add a couple big capacitors to quiet that down. I know I have some big old caps, but I'm not sure of the voltage rating. Wow it's been a long time since my EE classes. Can I string a couple in series...

    500w Cyclone Kit drains heaps of power! NO BMS!

    Hi Bill, Hmm, Interesting. My Cyclone runs in the CW direction. I still have not purchased a drainbrain or other device to monitor the current/voltage. I'll do some more testing with the Cyclone at higher RPM and see if it behaves better. I put a 20T cog on the Cyclone and it's driving a 406mm...

    500w Cyclone Kit drains heaps of power! NO BMS!

    I have a 500W Cyclone that I am testing on a recumbent bike, and am not too impressed so far. Do they need to be broken in? My 450W Currie cheeseball motor seems to be more efficient and powerful by far. My Cyclone got hot and ran down my 24V 20Ah battery very quickly as well. I was running it...

    The E-cumbent - A project by Matt Shumaker

    John Tetz retrofitted a current controller to his RC Servo controller, and has documented in on this page: http://www.recumbents.com/wisil/tetz/CurrentLimiter/default.htm He also came up with a nice spike reduction. His system uses an on/off switch rather than a varistor to control the speed...

    Finally! The Cyclone 500 watt review...

    Hi Pete, I have 3 gears left above the one that seems most efficient for 23MPH. I geared it for 30MPH at max RPM using my recumbent bike simulator: http://www.recumbents.com/wisil/simul/HPV_Simul.asp Not sure on the current. I guess I need to buy a Cycle Analyst. What kind of top speeds do...

    Finally! The Cyclone 500 watt review...

    I have been riding my 2007 vintage Mongoose-Recumbent conversion with it's 450 watt Currie motor for over a year now, and regulary see speeds in the 28MPH range. I just finished building a second electric recumbent bike, this one with a Cyclone 500 watt motor. Riding position is about the same...

    CudaE - Custom 450 watt 24V Currie recumbent.

    I spent most of Saturday working on the new ESC bike. I built a battery mount, added the larger 20T cog to the motor, raised the handlebars, and rebuilt the seat mount again to raise it a bit more. Today after dinking with the seat more and doing some inside testing, I took it for it's maiden...

    CudaE - Custom 450 watt 24V Currie recumbent.

    I'm using a 24V, 20AH battery sourced from forsenusa.com, which I obtained in spring 2007. It was $600. He wasn't too clear what type of lithium formulation it was. It consists of 6 rectangular hard shelled cells, and the whole thing was wrapped up in blue shrink wrap. It has been working well...

    CudaE - Custom 450 watt 24V Currie recumbent.

    My current e-bike with the 450 watt Currie motor has one very annoying problem where if the current gets too high (I think...) then the motor cuts off. It will not run until the power to the controller is turned off and back on, after which it's fine again until I accelerate to fast, or try to...

    CudaE - Custom 450 watt 24V Currie recumbent.

    Hi Matt, New bike is coming along. I brazed up the idler and motor brackets this past weekend. The 500W Electroportal OEMed Cyclone motor is very cool. It has a double sprocket mounted which allow rhe front and rear chains to operate independantly. The drive side sprocket is a standard...

    CudaE - Custom 450 watt 24V Currie recumbent.

    Hi All, I built this bike last spring to commute to work without getting all sweaty. It's working well. It started life as a Mongoose ($300) pedal/electric motocross bike, and I re-used the rear subframe, suspension, motor, controller, wheels, brakes, etc. The 24V Li Batt was sourced from...

    Aerodynamics thread?

    If you have a recumbent bike, a tailbox is the best way to gain better aerodynamics. If you have a road bike, buy more batteries... 8) Something like this Coroplast tailbox is cheap, easy to make and very lightweight. There are plans here...

    Aero e-bike concept

    Hi All. Long time lurker, first time poster. I have been thinking about this for some time. Current idea is for a side by side "social" tandem. It would be a faired tadpole trike with gullwing doors. Power would be pedal plus electric. The idea is to have it be fast enough to run with city...
