I do not recommend the M1. A significant amount of output is lost when the flashlight is zoomed in. Zoomed out, the flood is just too broad.
My understanding from discussions with bicyclists is that they need a “throwy” flashlight, to see obstructions far ahead. How far ahead depends on how fast you’re traveling and what type of obstructions you may be encountering. I have an S2+ and the beam is too floody for such purpose. The S2 has a deeper reflector is slightly more throwy and might be usable. (I do not have an S2, so I cannot verify.)
My D80 has not yet been delivered, but it sounds like it would be suitable for your purposes. 1300+ lumens max output and 20kcd beam intensity. Small, compact form (not as small as either the S2 or S2+, but comparable to M1). $20.59. See discussion: GB BLF LuckySun D80-SE Need long tubes? -3/3/16
You can choose output levels from any one of 5 modes (message no. 1690): GB BLF LuckySun D80-SE Need long tubes? -3/3/16

There are much throwier flashlights (such as the C8) in the same price range, but they have even larger heads. The D80 strikes a good balance between output, beam intensity, size and cost.
As to choice of tints, my understanding from previous discussions with bicyclists is that they need the high contrast offered by cool white beams. If that is so, choose the 1A version. However, if eye comfort is your preference, then I would suggest the less harsh neutral white 3C version.
