Great choice!
IT'S PERFECT, EXACTLY WHAT WE NEEDED.
Looks awesome
Perfect for my yeti
Universal Adjustable Bottle Cage with Anywhere Strap Adapter
Perfect fit for my new Magnum E-Bike!
Great
Works great and so do the brakes
Well made and very simple to use. It's the perfect size for my Samsung Galaxy A36 and with the padded insert, I can also add my garage door opener in addition to my phone. The velcro straps hold this bike wallet firmly in place and attaching it to my bike was really easy.
Locke is adjustable on the frame easy to use easy to reset the combination. Cable is sturdy and prevents where on the bike frame.
Both my bike and my wife .
Super fast delivery, simple install, and works great. We use it to navigate and live it!
Fits bike well
Very nice mirror well made doesn't become out of adjustment every bump you hit 👍 and looks great great quality.
I love everything about my magnum low rider, bike is awesome. Have mirrors, cup holder, saddle bag , blue tooth speaker, foldy lock, plus another lock, degreaser for chain , chain oil, basket, head light and helmet, and bike polish, tools, bike tire pump, pressure gauge. Have fun when I ride! I’m old. But discovered a new sense of freedom.also get exercise, by choosing to pedal, but love having power. Thank you for experience of freedom. At first I was scared, perhaps clumsy/ uncoordinated. Oh but not now. King of the road. Like always Safety First.
Excellent for keeping an eye on things. Easy to adjust.
It's not fitting the rack like it's supposed to. It won't clip on.
Great if you are in traffic
Wherever I ride, folks are impressed at the quality of the bike and the additional equipment. Love it!
Saddle bags very roomy.
this is installed to my Magnum Low Rider 2.0. It gives me good visibility to rearward coming traffic. However, it shakes constantly but stops if I place my hand on it. I think its' light-weight makes it susceptible to a resonant frequency.
Basket stays loose not theft proof
Works great!
The cover for the battery charger broke. The rubber cover replacement was not available, so I ordered cover for something else and the full cover. This new cover fits snug , and fits other bikes but still works nice for this bike, wife also like the small pouch . I’m thinking of getting one for my bike.
E-Bike Battery Cover - Weather Protection & Insulation (Universal Fit)
perfect
Bags are fine. The straps don't work great on the top bike rack. They are hard to put on with the design. The bags are roomy though and we will see how thry do in rain/snow.
Nice
Another HORRIBLE design. Clumsy, in the way and no instructions.
Universal Adjustable Bottle Cage with Anywhere Strap Adapter
Horrible design. Clumsy and invasive. Would NOT recommend. Also no instructions. Had to look at pictures on website to figure out.
Came with no instructions on how to set the lock
Very nice, good quality fabric and design.
Clumsy and in the way.
I have only used the mirror a few times and so far they are working great.
👍
Works will
Easily put together, excellent bikes. 1 have 1 charger that doesn’t work, will contact them directly. Two excellent bikes
What an amazing design. It adjusts so easily, and won't become obsolete as water bottles, etc continue to morph in size & shape. The long & sturdy velcro strap made it easy to find a good location to mount the holder on my bike -- accessible but not interfering with movement.
Universal Adjustable Bottle Cage with Anywhere Strap Adapter
Solid! No concerns about my phone slipping out or even shifting position. It takes a bit of practice in slipping it back out. I want to tell it "Let go please!" I was able to position it so I can set to record & video portions of my ride. Love the extra clamp feature. Easy to install (although my handlebars are starting to get a bit crowded)!
Excellent quality; easy to attach; and I feel so secure being able to glance at the mirror instead of turning my head to look back.
