Magicshine Evo 1700SD review: What if you could control your bike lights with your Di2 shifters?

There has been something of a shift in the best bike lights recently. Previously it’s just been a matter of mounting a big battery tube to your bars with a light at the front of it and controlling everything with a button. In recent seasons I’ve seen a growing number of smart lights, with added automatic features, and lights with remote controls. 

I recently reviewed the Magicshine Ray 2600B, which came with an on-bar remote control, and while it wasn’t perfect – in fact the user interface was annoying enough to be almost fatal – being able to control the beam easily without reaching under the stem was very helpful at times.
