A larger size that can also house a smart phone, so that you can charge up as you ride.
Clean up the handlebar cable clutter. This neat little bag rests on top of your frame. Inside there is a velcro strap to hold your battery pack still and secure. Simply feed the cable through the slot, and stash the excess in the bag. Made from recycled inner tubes this makes for a highly water-resistant, and durable bag. There is enough room for a 6 cell battery pack, some keys, and some wire.
Perfect companion to our light sets to keep your bike looking clutter free, and protecting the cables and batteries from the wet.
