What a great way to close out the end of the day by riding our magnum e-bikes watching the colors in the shy change while feeling the cool breeze on our faces after a hot day.
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.
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.
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.
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.
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.
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.
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)!
