I really like my 900 lumen Nightrider front/rear light combo pack that I got from REI for $150USD or less.

Easy to attach/take off the bike (crucial to avoid theft while locking up in town), battery life is decent and doesn't wobble when I hit bumps. Just gotta make sure.youre familiar with the "lock" function; it keeps the light from accidentally turning on in your bag. I forgot about it and thought my light broke so ended up spending like $113 USD on a light with 1100 lumens (i wanted 900 but it wasnt availabl) that jumps around a bunch and I HATE IT. Then I looked it up online 6 months later and figured out my night rider works after all! Lol

I just looked it up and it seems like niterider has changed their design and uses the same attachment piece as cygolite now (the light I hated). It's probably user error but it barely fits around my Salsa Cowchipper handlebars. I think I had to take off the anti scratch cushions to make it work. Hopefully that's not an issue for you.
