Motorola’s customizable Moto X smartphone can now be ordered with a wooden back panel. The option was originally shown in press photos when the handset launched during the summer but unfortunately, the attractive backs were pushed back.

A quick check of the Moto Maker website shows a wooden back option under the Natural category. The bamboo rear cover will set you back an extra $100 and is currently the only wooden choice available. That means prospective buyers will be looking at $199 for the 16GB model and $249 for the 32GB bamboo model, both with a two year service agreement. If you want the phone without a subsidy, expect to pay $599 and $649 for the 16GB and 32GB models, respectively.

Motorola initially showcased multiple wooden backs but eventually said they required more research before they could be offered to consumers. Specifically, Motorola’s engineers said wood’s signal propagation properties are different from traditional resin which meant more time was needed to figure out the equation.

The company promised to deliver them before the end of the year and well, I guess they made good on that promise. Rumors suggest three other wood options may eventually be offered but Motorola hasn’t confirmed anything as of writing.

Because the handsets are assembled in the US, the company is able to deliver custom phones within four days. Unfortunately, that isn’t the case with bamboo backs as the Moto Maker website reveals an eight day estimated delivery window.
