The battery case straps to the hub via two plastic tie lock straps. Once the wheel starts moving I can't help but wonder how well the battery case keeps it's place ( once rotational inertia kicks in ).

A couple things are very clear with the Monkeyelectic's. They are very bright and very cool to look at ( at night ). Downside is that mounting is not easy on / easy off. This means you aren't going to want to take them off for day rides unless you have a good supply of the black plastic straps on hand and don't mind the fuss. Otherwise, be prepared to look at them on your wheels during the day.

I hate having to look at the Rimfires on my bike during the day but taking them off would be way too much of a inconvenience. At least the clear plastic of the Rimfire battery hub is not too noticeable when the bike is moving. There are some minor balance issues with the Rimfires so getting it all to work is not always easy. This is why I'm continuing to look for a simpler solution, one that is easy-on / easy-off yet still bright enough to draw attention.
