What type of bicycle bell is easy to use with winter gloves? In the winter, I often ride with mittens and find it impossible to use my standard bell (the one where you bend the clapper and let it hit the body), because my thumb touches the body and mutes the sound. Even in normal gloves I find it difficult to ring the bell. What types of bicycle bells work with winter gloves?
I personally have found that anything with a lever that moves the internal clapper works best. Unfortunately, those seem to only come in large size.

Here's a photo of the one I have lying around:



I thought the spring in the internal mechanism had worn out which is why I wasn't using it, but now that I looked at it again it turns out it just needed a bit of oil.

Here's what the insides look like:



The clapper's attached to the lever with a spring so any contact with the lever won't dampen the clapper's movement.
