Freight bicycle
Thanks for the contribution to the freight bike article. It all looks like it's moving the article forward to me. And thanks for adding the message to the talk page. It's good to see that you're putting the effort into communicating with the other editors. This is completely unofficial (I'm just an occasional editor myself) but welcome to wikipedia! Good to have you here. --Keithonearth (talk) 06:28, 16 August 2011 (UTC)

Welcome!
Welcome to Wikipedia, Dr2chase! Thank you for your contributions. I am Ebikeguy and have been editing Wikipedia for quite some time, so if you have any questions feel free to leave me a message on my talk page. You can also check out Questions or type at the bottom of this page. Here are some pages that you might find helpful: Also, when you post on talk pages you should sign your name using four tildes ( ~ ); that will automatically produce your username and the date.

LEDs
I think the LED section is outdated and no longer accurate; it gives the impression that LEDs are finicky and generally inferior to other choices, and that is no longer the case. Modern power LEDs emit adequate light at a few hundred milliamps, yet can handle (if heat is dealt with) as much as 3 amps, so whatever problems there were with overpower are now not an issue. This is especially true for those LEDs driven by hub or sidewall "dynamos" (more accurately, magnetos, they all produce AC), because those generally produce not more than 500mA of current. I am not sure where to get a source to back up the assertion that the electronics are now reliable -- note however that power LEDs are now widely deployed in home lightbulbs and automobile lights. It is also the case that modern power LEDs are a good match for very lightly processed output of hub and sidewall magnetos; in the most minimal circuit two LEDs are wired in parallel opposition, so that the positive half of the AC current lights one and the negative half lights the other. In this case there are no other components to fail except for the wire itself (which happens from time to time).Dr2chase (talk) 22:46, 15 January 2014 (UTC)
