The Kilowatt Bag is NOT steathy, stylish or ergonomic. Its sole design considerations are to mount as easily as possible and to hold a LOT of LiPo batteries. It is Utility, pure and simple.
The design is a “Top Tube Saddle Bag” that sits in front of the rider, mid-frame for good weight distribution.
The bag is made from 1000 denier Cordura on the exterior and Genuine Nomex Fire-resistant fabric on the interior. The compartments are lined with 3/8″ thick closed cell foam to provide some protection to the batteries. However in the event of a crash, there is potential for battery damage unless the user provides additional rigid structure to the batteries. 1/8″ Masonite may be a good solution for those interested in additional cell protection, and should not add significantly to the weight or volume.
If you already have a Falcon EV triangle frame bag or EM3EV triangle Frame bag, or other similar triangle frame bag, the Kilowatt Bag can strap over and around the Triangle Frame Bag.
The bag has large compartments on either side. The interior clear dimensions of each compartment measure approximately 3″ wide x 8 7/8″ Long x 7 1/2″ Tall. This space was optimized to fit a wide range of common HobbyKing LiPo (Multistar) batteries, as well as an array of up to 11 x 11 18650 cells per size, for up to 242 Cells total.
The Kilowatt Bag hangs low and may collide with your front wheel, depending on the size and geometry of your bicycle. There is some adjustment on the front strap to allow rear movement of the bag towrads the bicycle seat. Users should mock up the bag dimensions on their bike frame prior to purchasing.
The bag is fairly wide and may rub the riders legs when pedaling. The purpose of this bag is to allow for ample battery capacity so that riders will not need to pedal.
While the bag does have top flaps, to keep rain out, it is not completely sealed against weather, so some water intrusion is possible when exposed to prolonged or heavy rain. Wire management & routing (by others) may also contribute to water intrusion. It is recommended that users remove the batteries and air-dry the bag after a wet ride.
This bag is currently crafted locally in Seattle, Washington using quality materials, by a professional seamstress.
