Do Dynamos work if they roll the opposite direction?

I have the 2014 Cotic Roadrat (pic attached of Dunwich Dynamo set up).

The fork has the disc brake mount on the right-hand side. If I buy an off-the-shelf dynamo wheel, will it work? If so, does anyone have any advice or tips for choosing a good quality dynamo hub?

The electric parts don't care but you might conceivably unscrew something inside leading to sad times.

Schmidt says their newer hubs can go both ways, so use one of those.

Is the sense of rotation important on a SON hub dynamo?
All current SON hub dynamos do not have a defined sense of rotation. On a SON 28 klassik (year of manufacture until 2011) the connections must be on the right side, so that the threaded lid does not come loose.

Please tell me that somebody says you’ve put your forks on the wrong way round at least once a ride. It’s the only reason I ran one on my tricross.

Lol yeah, it does attract some backhanded comments every now and then - 'I wonder why they did that...' 'That's unusual', 'That's ugly' etc.

I’ve run a dynamo on a roadrat with these forks. Worked fine. Nothing unscrewed. It was either a SP or SON hub dynamo. Think it was an SP.

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
