I haven't tried these new 2022 trails yet but a friend has and they seem very novice friendly. They are in a part of town with limited trail opportunities until now.
Storing some information here to update when I do them:
Parking for trails: 45°09'47.7"N 93°06'16.4"W
Trail info: https://www.alltrails.com/trail/us/minnesota/rice-creek-chain-of-lakes-mountain-bike-loop.
"many miles of trails in at least five different nodes of the park. The trails are heavily wooded and surrounded by lakes. There are sections where biking or hiking on paved trails is required to get to the next node."
