About the Arundel Looney Bin
The Looney Bin from Arundel is an adjustable bottle cage that fits bottles from 65mm to 95mm in diameter — standard cycling water bottles, a thermos, or a full 32oz Nalgene. The spring-loaded ratcheting mechanism grips any bottle securely, which is why we use it as one of our two options for carrying a spare Temper Battery.
Includes the cage and mounting bolts for standard water bottle bosses. If your frame doesn't have bosses, or you want more flexibility in placement, add our Battery Mount Adapter to mount this cage anywhere on your frame.
Is this the right spare battery option for you?
- Ratcheting Bottle Cage — best if you want to swap between a water bottle and a spare battery, or if you only carry the spare on longer rides.
- Spare Battery Mount — best if you want the spare permanently mounted with a locking mechanism for added security.
