Specialized Turbo SL Range Extender Battery

Great battery, slow shipping.

The battery does exactly what it is supposed to. 50% more juice for those longer rides. The purchase experience was disappointing. The website says "Ready for pickup in 2–4 days — Or ships today" In reality, it shipped more than a week after I placed the order.

Great addition to bike

Got this for me and my wife to go riding for longer distances. Solves the range anxiety with the SL bikes.

A life saver

I bought this extender as I had to do a 102 mile run (and didn't want to let my friends down), and was totally not prepared as work kept me away from my Creo 2 for weeks. Install was easy, my display upped my available capacity from 100% to 150%, and I was able to finish my century ride with around 15% of power left. The ability to install an extender, is one of the many reasons why I like my Specialized Creo and Levo SL bikes.
