Hi ExtraSilver. I'm think of doing your exact build on my single speed bike in London.

Couple of questions:
-What gearing ratio do you recommend? On my bike setup i currently have 47t/17t which I think might be too high a gear for the TSDZ2 motor. I understand it comes with the stock 42t crank but I think this is going to be too low for my desired top-end. What gearing ratio has worked best for you?
-I'm thinking of installing a throttle at a later date to make thing even easier but I'm worried about the motor struggling from a start if using a throttle.

Any experience on this set up would be really appreciated.

Thanks

Not wishing to teach your grandmother to suck eggs but don't forget you are restricted to 250W output here in the UK whereas Extra Silver is somewhere in Germany and is not restricted.

Not a problem. I will be getting the 250w version.

Formatting Help

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:
![](https://www.google.co.uk/images/srpr/logo4w.png)
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.
