Hi bob got it! would need to use bidirectional?? so one end of the tvs to the centre pin of each phase on switch (inside controller) and other end of tvs to...
just another thought, this could be way off the mark, but if you used a bidirectional would the earth for one of the tvs (in the pair ) be the positive rail,...
I did some experiments with a brushed 36v hub motor with regen, the amount of energy available from regen is actually very large, on that motor at 10km/hr...
Hello Bob, using the A123 seems to be in the same price range as the Valence. ´However this is true only for 24 V system, right? 19Ah at 48V is a lot of...
There was a schematic on this list with a current limiting device connected through the throttle. It may be a better solution than a circuit breaker. /Bruno ...
... Yup. that is neat all right, but it comes at the expense of complexity. Call me a Luddite or something but I really like the KISS principal. I look with...
Hey Dan! I think we already have such a device, and its called "a brain" Many of the Lycra bike shops sell max-min heart rate monitors which give different...

bionx- complex- yes. Added weight- no. They have high torque, much lighter than any non-geared,hub, brushless motor I have found. And they only use nimh or...

... Actually, that isn't a bad idea, especially as one can keep an eye on the road and don't have to read a bloody meter. Even more gentle would be a small...
It's fascinating information, and it looks like it might be worthwhile for racing cyclists. However, disassembling the roller and pin from each and every chain...
Had a low value circuit breaker on a e-trike a few years back. It tripped while climbing a hill in bad traffic, just as I had it set to do. After extracting...
I rode a bionx with selectable pedal assist proportioning and it was very smooth with no sense of action/reaction. I don't know if there is a system which...
I use an ESV that is rigged to 28v top and 24 bottom. It shows the "fuel available" in the battery when there is no current flowing and is shows the voltage...

I got a chuckle when I read your first post, Dan, and it was followed by a larger one for this post. I've enjoyed Sheldon's genius for a few years and I'm...
The chain cleaning part was kinda obvious to me, but I fell for the nano chain part. Really silly, but shows how much I know about Sheldon Brown and bicycles....

Folks: I've got a PowerTap computer and hub installed on the same bike as a Cyclone 500-watt system. Unfortunately, when I run the motor, the PowerTap display...
