The bike rolls the length of it's wheel's
circumference with 1 revolution.
+C+=+2%2Api%2Ar+
and
+d+=+2r+
+d+=+1+ m
+C+=+1%2Api+
The bike travels in a straight line
+132%2Api+ m/min
---------------------
Convert [m/min] to [km/hr]
[m/min] x [km/m] x [min/hr]
+%28+132%2Api+%29%2A%28+1%2F1000+%29%2A%28+60%2F1+%29+
+%28+132%2Api+%29%2A%28+6%2F100+%29+
+1.32%2Api%2A6+=+7.92%2Api+
+7.92%2Api+=+24.8814+
His speed is 24.881 km/hr
