Solved all my problems!
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! ... show more

Triple bob battery mount for the win
The Triple Bob is a versatile battery mount. It's not the most elegant looking solution (when used with the hose clamps) but it does work very well. To be fair, there aren't very many solutions available to begin with. This allows you to use your existing water bottle mounts or to use the hose clamps to mount an ebike battery to different sections of your bike tubes/frame that you may not have been able to secure a battery to prior. On a bike frame where you have limited space for 1 battery or a 2nd battery, the triple bob gives you a few more options to mount the battery to the frame. As countless others have mentioned, the fit is great, it is secure. This mount sometimes is your only and best option ... show more

Why are you reading this review just buy it
I’m not sure why you’re even reading a review. This thing is amazing. You need it in your life. I’ve been a bicycle mechanic for more than 25 years. I’ve been messing around with electric bikes for around five years now. This is by far the absolute best addition to any electric bike that uses a water bottle style bolt on frame out. Or if your frame has no water bottle style mounts. I am using this on a surly karate monkey with a 52 V 17.5 hour shark pack. Mounting this to the bike with just the mount it came with is not secure it wobbles and is not in steel high confidence. The bike I’m using it on actually has three water bottle bolt mounting holes, so I was actually able to mount this using all three bolts and did not have to utilize the band clamps. However, if you need them, they are there and will make the install insanely secure. Or the really nice part. If you don’t have suitable mounting locations, these band clamps will offer you an ultra secure mount for your electric bike battery pack. Seriously why are you still reading? Go hit the buy it now button. Trust me you won’t be sorry. ... show more

Perfect Solution for Mounting Battery
On my bike, I could not attach the battery to the water bottle mounts. If you are putting shark battery on a home conversion ebike, go ahead and order the Double or Tripple Bob. You will be glad you did! Very easy and secure mount.

Works real good
I have a bafang mid drive on my surly cross check with. 17ah batt. But the original mounting bracket that came with kit allows batt to flop, or have a bit of play, when I hit bumps, potholes. For a long time I used a voile strap to keep it tight but have finally upgrade to the professional solution that is Triple Bob. I did have a few issues with installation, did not notice the screws provided had a recessed head and was trying to use some of my original bolts. I think since their are 3 different types of screws the instructions could try a little better but of course I figured it out eventually. The batt is super solid now Night and day difference In my opinion every batt should come with one of these, when relevant, it's just proper.design Good job Triple bob ... show more

Great product!
I had my heavy ebike battery originally attached to downtube with just the two water mount brackets which worked okay but seemed kinda flimsy. This mount is a lot sturdier. Easy to install and there are helpfull videos on YouTube.
