    • 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

    • 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.

    • It does exactly what it's supposed to do!
You can't go wrong with Grin stuff. Those young engineers in the great country to our North and really on top of E-Bike kits. Not my first purchase from them and surely not my last.

    • Precise Dimensions Required
Im sure this adaptor plate is fine for smaller batteries. Alas, it was not suitable for my shark size battery, with 3 slots in the battery adapter. It would be good if GRIN included More Precise measurement Dimensions of their adapter plates. I had to return it for refund. Anyway- its A well made battery mount plate with all fittings included. ... 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

It’s not related to this product. But I order a Bafang e-bike kit and this little bracket save me from giving me the worst headache. Anyway, this is perfect for mounting your battery anywhere you want to be. I highly recommend this if you want a more secure hold and if the battery can’t fit in the frame of the bike. ... show more
