This is probably most important and most frustrating thing you'll have to do with your SPIN - once you put it on our wheel it stops to be a problem, and starts to be fun.

more is better?
Before you start fiddling with zip-ties you should consider one thing - how many SPINs you're going to mount on your wheel, and which wheel to mount them on. Going through similar devices available on the net, I've realized, that one has to buy at least two POV modules of competitive solutions, to get satisfying effects. Why is that? Because virtually every solution out there uses only one row of LEDs, so if someone wants to get two lines of LEDs, he has to pay double.

It might sound like a cliche, but "more means better". One SPIN module is usually enough to get nice effects, but two of them are... two times better - if you decide to use 2 SPINs per wheel, you get 4 lines of 32 LEDs which believe me, is worth the money.

1. what you'll need
Off we go. Basically, to install SPIN at your bike you'll need the module itself, some zip-ties and the magnet, however pliers and cyanoacrylate glue might come in handy.

2. use zip-ties
As you can see SPIN is rather lengthy than wide, so it should be quite easy to mount it parallel to the spokes. Now take a deep breath and before attaching anything permanently try to remember, that batteries' holders should finally appear close to the center of the wheel, which means not close to the tire! Use zipties to fix first board to the spoke of your choice. Do not tighten the zipties yet!

3. use tools to get to cramped places
Carefully mount the inner part of SPIN. This part is important, as it will counter the centrifugal force, trying to rip SPIN out of your wheel. Now is the good time to use pliers if you have one.

4. be precise playing with sensor
Once you've attached both modules to spokes being in line as much as possible, It's time to mount the magnet, and bend the sensor firmly so they can 'see' each other. You're ready to go!
