    • Great
Well made and did exactly what is was supposed to do.

    • Help to keep heavy e-bike battery stable
I have a odd shape bike frame that is not round so tried this mount adapter, really make the battery mounted stable on the frame and does not wobble at all.

    • 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. ... show more

    • 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.

    • Just what was needed
Got a pretty decent deal on a Xtracycle Edgerunner and decided to add a Bafang BBS02 since I'm not getting any younger. This and a small adapter were exactly what was needed to add e-assist. Got nearly 1000 miles on the kit and couldn't be happier with the layout.
