The Triple Bob allows you to install frame-mounted battery packs on bicycle frames without water bottle mounts. If your bike's water-bottle mounts are not in the ideal location this can be used to locate them anywhere you want them. It is often more secure and stable than the original water-bottle mounts so you may want to use one of these regardless if you have a heavy battery. Flat plastic covers for hose clamps provide an attractive fit and finish for e-bikes.
The Triple Bob rail provides for a convenient and secure means of attaching any of the Electrify Bike Shark batteries as well as other Hailong and Reention case Downtube batteries to any location on the bicycle frame tubing regardless of the eyelet position. These pieces are CNC machined from solid aluminum stock and provide a wide and flat platform for the battery cradle to rest, secured with three M5 bolts so there is none of the rocking or play that is sometimes present with water-bottle eyelets. Machined channels allow up to 4 hose clamps to keep the battery tightly in place. Designed and made in Canada by Grin Tech. Here is a link to a Grin Triple Bob video.
