Double Bob and Hose Clamps for Secure Mounting of Large Hailong-03 Downtube Batteries. Review: A must have for difficult battery mount on EBike - Built a Cannondale Rush 7 E-Bike and it took a little finesse to get everything to mount properly but this mount was key to getting what I wanted in the way of power. This mount made it possible to mount the 52v 17.5 amp hour battery on the bottom of the lower tube. Really solid, was easy to install and comes with shrink wrap for the clamps to make them blend in better. Nicely machined too. Review: Secure battery mount - Must have mounts battery securely and robust.

Secure battery mount
Must have mounts battery securely and robust.

Very sturdy ebike battery mount
Water bottle cage inserts were not really made to handle the load that a heavy ebike battery puts on them, especially on mountain bikes. I highly recommend adding this kit to your installation to better secure your battery.

My battery is now stable
My ebike battery was wobbly and saw this product so decided to risk it and try it out. My battery is now rock solid ... even when riding over pot hole after pot hole. My only compliant is the documentation for this is weak and I had to spend some time figuring out this assembly.

Great alternative to weak battery mounts
This is well made and a much more secure way to frame mount most kit batteries. Whether you have braze-on water bottle mounts or not, it shifts the clamping to the entire tube section, not just a few small points.

Worked as advertised. But required a bit of work.
Got a QWW downtube battery the problem as with most Haillong types is the bolt holes are high and most bikes bottle cage bolt holes are lower down, so to make the battery get mounted required this bracket. The two upper bolts are now securing the battery and I added an extra velcro and electrical plastic thick strap lower down as the two securing holes are at the top. Seems very solid, will follow up if anything else happens but this appears to have done the trick.

A must buy
GREAT for DIY E-Bike kits. Holds up battery extremely well with the extra attachment points. Have on both of my Bafang kits.

Grin double bob
Well made mounting bracket. The shrink tubing for the hose clamps is a nice touch. The 9 lb battery is very secure and well positioned on the downtube. One star off because of import fees charged. This is a Canadian product, made in Canada, but shipped to Canada from the United States. What?
