There is an unusual, rear-steer delta trike called the Mobo Triton Pro which I'm considering going Dr. Frankenstein on. It has a 20 inch, pedal driven front wheel... but what if the seat faced the other way and the now-rear wheel had a hub motor? It would then be an electric-only tadpole. At...

My Lyric Ranger has one good battery pack and one bad one, so I've been looking at alternatives. After some voltage and resistance measuring I figured out how to connect four 12v SLA batteries in series to the terminals which stick up where the original batteries would plug in. In this pic, the...

I bought a RideKick powered trailer recently. Noticed that the controller was tripping quite often. Took a look at it, and discovered this: The heat sink only contacts the edge of the right-hand FET. Clearly it's a production error - the pad of heat-transfer stuff is the correct size but...

I've used these for cold-weather motorcycling and they work well. Just make sure they're Velcroed on carefully so the closed ends are actually closed :)

There are many disabled folks involved in motorsports, ebiking or otherwise - while being autistic doesn't impair my pedaling ability it makes life interesting in other ways. I wanted to say that before passing along something else disability-related which I thought was very funny. The British...

One other factor: jumping a 3-wheel ATV and landing on the front wheel is a great way to get maimed or killed if that wheel doesn't stay pointed straight ahead. IIRC some ads for the things even showed them being jumped, even though the consequences of doing it wrong were so harsh...

Just ran across this thread. It looks like the poster of its second message thinks that likening something to the Special Olympics sets the bar laughably low. How sadly mistaken. Take it from someone who has watched his kid compete in the Special Olympics: you have no idea how high you've set...

Per month? How did you arrive at this conclusion?

The fellow who used an ultracapacitor as a power source wound up putting a bolt through the axle to stop rotation, but there's a lot more metal in your setup... http://endless-sphere.com/forums/viewtopic.php?f=6&t=7511&hilit=ultracapacitor&start=30#p122326

Not if the testing involved both dropouts... might it be feasible to test the dropouts on each fork separately - that is, one side at a time? There may be an obvious-to-everyone-else reason this wouldn't work, but figured it couldn't hurt to ask.

And on the side where the wires exit, it could help protect 'em in the event of a spill. Instead of a thread-on thingie with fins, what about a larger piece of stock which ran up alongside the forks? More mass, more surface area, more airflow across it... and imagine the styling possibilities...

If I could try to extend the comparison a little - imagine trying to take a shower under the bucket, and look at voltage as being how high the water is in the bucket. So a big stream of water from a shallow bucket would pour out but not very forcefully. That'd be a lot of amps at low voltage...

I wonder if anyone has tried welding two-piece torque arms together once they're adjusted properly... wouldn't this help make the assembly more rigid? Any small tendency for the axle to rotate would be turned directly into push or pull against the fork tube. I realize this should happen...

It's a question of using the right tool for the job. My current Netflix disk is six episodes of a PBS series called "e2: Transport". Just watched an episode about the bike-rental system used in Paris - those machines are heavy-duty, and just for a moment I mistook their drum front brake for a...

+1 for referencing the original version of a movie sent up on MST3K 8)
