When purchasing scooter bars, you need to take a couple of things into account. First, what scooter compression are you running. The Envy Reaper bars have an oversized outer diameter, standard inner diameter, and a slit, which makes them compatible out of the box with ICS and IHC compression. If you cut the bars down to remove the slit, they can also be used with SCS compression. Once you know the Reaper bars are compatible with your scooter setup, people often consider how the bars look. In our opinion, the Envy Reaper and Union bars are simply the best looking bars in the scooter industry. Scooter bars are currently made of 3 materials - aluminum, steel, and titanium. Reaper bars are aluminum, which are much, much lighter than steel bars but do not offer the same strength that steel bars do. Titanium bars offer the best of both worlds - the light weight of aluminum with the strength of steel but are very expensive. So, if you don't have $200 - $300 to drop on titanium bars, aluminum bars are the way to go if you are looking for a light weight setup. If you thrash your scooter and are hard on your bars, steel bars may be a better option for you. We rate the Reaper bars at a 4 for one simple reason - they're not titanium bars. When pushed to the limits, aluminum bars can break so we prefer titanium. With that said, if you are in the market for a quality aluminum bar that looks great, the Envy Reaper bars are the scooter bar for you.
