All bicycles sold at REI include a free warranty tune-up. New bikes go through a normal break-in period, after which readjustment is important for longevity and performance. Bring your new bike in to your local REI for its free tune-up within 20 hours of use or 6 months from purchase, whichever comes first. Contact your nearest REI bike shop to schedule this important service.

I don't see a size chart for the Ghost Square Urban 6. Would a Medium be the right size for a 5' 7" rider with a 30-inch inseam?

Asked by: Arlington Biker
We are working to provide an updated bike size chart. Below you can see the standover heights for small and medium. S standover is 29" M standover is 30.3" If your pant inseam is 30 inches then your full inseam is probably about 31 or 32" which would mean the size medium is most appropriate.

I love this bike but what's up with no chain (belt) guard. It is a commuter bike! They went through the trouble of fitting it with fenders. Can it be fitted with a guard?

Asked by: lkshrtrl
It might be possible to fit this bike with a chain guard and you will want to consult a bike shop for details. Here is an REI store contact list where you can contact an REI bike shop; https://www.rei.com/map/store

Am I viewing the photo correctly - the top of the rack is *lower* than the top of the rear wheel? How are you supposed to mount anything to the top? Or is the idea that panniers would just drape over the fender?

Asked by: SagaciousB
The integrated cargo rack is lower than the top of the wheel.

Can this be fitted with a 'Grip-shift' type shifter?

Asked by: Melz
​The Alfine disc hub on this bike comes with Alfine SL shifters that are designed to work well with this drive system. We do not recommend using grip-shifts.
