I saw this motorized bike or another near Cal Expo heading faster than other traffic up the trail about 4:30 PM today. It left a trail of fumes and others had to dodge as the rider zoomed along. It's not uncommon to see these illegal bikes on the Parkway & N Sac bike trails.

From this report on the north side of the river and my own observations just across on the south, this appears to be increasing in frequency, apparently on both sides of the river!
