Why You Should Always Use A Triple Bob To Mount A Down-Tube Battery

Let me qualify that.  We have tried the Triple Bob from Grin Technologies with all of the Retention shark-type cases we use and most of the Hailong shark cases, and it dramatically improves the strength and rigidity of the mount every time.  We are now recommending them with all of our downtube batteries.  Grin Technologies Triple Bob Ebike Battery Anchor Bracket Mount While they improve every support, they are most important on Jumbo Sharks and Mega Sharks.  These weigh from 9 to 12 lbs and are taller, so there is more side-to-side leverage pulling on the mount.  With a Triple Bob, the battery is on its rock solid and doesn’t move.

The problem is solved because the bottom of these batteries is flat, and the downtube is round.  It leaves only a few M5 bolts to hold the entire weight of the battery against any side-to-side forces. It often leads to a storm that “wiggles” from side to side or, in some cases, “flops” from side to side even with the bolts fully tightened.

The ingenious cure Grin came up with is to provide a V-shaped trough in the bottom of the

Triple Bob.  This allows two contact points the length of the Triple Bob on the round bike frame about 15mm apart to provide a stable platform for the battery.  They also raised the threaded bolt holes for the battery mounts to fit the recesses in the mountain, so the bolts tighten down snugly with no gap between the battery mount and the Triple Bob.  Here is a link to a Grin Triple Bob video.

Downtube Battery Mounting issues

Grin Technologies Triple Bob Ebike Battery Anchor Bracket Mount

So my new hub motor kit came with a 17.5ah battery. It’s usually a down tube-style battery plugs into the water bottle slot, but the holes in the space don’t align with the existing place on my bike frame.

Any ideas? I want to keep the battery inside this frame triangle, Grin Technologies Triple Bob Ebike Battery Anchor Bracket Mount  I can drill a few holes and add extra rivet nuts, but I’m worried this will weaken the edge also afterward. Also, feeling the weight of the battery, I’m scared these are cheap aluminum nuts. They won’t be strong enough to fix it in place.
