Grin Technologies TripleBob Ebike Battery Mount for Secure Downtube Battery Attachment - CNC Machined Aluminum, Black

It makes the Hailong-based batteries sit very tightly on the frame and allows you to adjust the vertical position, whereas previously due to the low position of the bottle screws you'd be forced to install the battery up-side down and it wouldn't sit very snug either. The kit comes with everything you'd need when encountering different scenarios, and the materials are top notch.

This thing is AWESOME! I am so happy this product exists!! I just converted my bike to an e-bike and there was no good way to attach the battery to the frame. It was too big for the water bottle holder area and I really didn’t want to drill holes into the bike frame. Especially with the extra weight the motor and battery added, I didn’t want to compromise the structural integrity of the bike.I ended up using electrical tape and a bunch of zip ties which didn’t look very good and didn’t hold well, the battery would keep slipping off-center. It also meant I wasn’t able to take the battery off to charge it or take it with me to prevent theft since the battery lock was obsolete (if someone wanted to steal my battery, all they had to do was cut through the tape and zip ties).I am so glad I found this product in my research, I was worried the holes wouldnt line up with the mounting plate of my battery since I didn’t order it through the same company, but it was perfect! The hold is super secure with the hose clamps and the battery feels very sturdy on it.My battery is pretty big and heavy and it attaches to the Bob with 3 small screws so hopefully it will hold up while bumping along the road. I feel much better now too that the hose clamps are much harder to get through than the zip ties and electrical tape if someone wanted to steal it, but now I have the option to take the whole battery with me if I’m that worried about it. I am soooo happy with this purchase and thankful this product exists!

After I mounted 48v 25ah battery on my bottle mounts I realized it was too heavy and too wobbly. This is just what I needed for a nice sturdy mount without worrying about my bottle mounts being ripped out. Works and fits perfectly.

I was very skeptical that this product would be sufficient to hold the battery in place without it shifting to the left, right or braking off entirely. I used to use metal hose clamps all the way around the top bar of the bike, having the battery dangle under it which held things in place very firmly. This product, I would say, works just as well (I'm using both the screw mount AND the hose clamps with rubber cover) and looks 10x better. Would recommend.
