Summary
In the City of St. Peters, Missouri, the traffic code splits electric bicycles into three classes by top assisted speed, and only Class 1 and Class 2 e-bikes may use the city's multi-use trails. Class 3 e-bikes, which keep assisting up to 28 miles per hour, are barred from every trail, and motorized bicycles are banned from all of them outright.
1.

Class 2 electric bicycle — an electric bicycle equipped with a motor that may be used exclusively to propel the bicycle and that is not capable of providing assistance when the bicycle reaches the speed of twenty (20) miles per hour. 3. Class 3 electric bicycle — an electric bicycle equipped with a motor that provides assistance only when the rider is pedaling and that ceases to provide assistance when the bicycle reaches the speed of twenty-eight (28) miles per hour. ... ... D. It shall be unlawful for any person to operate any electric bicycle other than a Class 1 or Class 2 electric bicycle on any multi-use trail in this City.
Full Breakdown
Section 300.010 of the St. Peters Municipal Code defines three classes of electric bicycle by how the motor delivers power and where it cuts out. A Class 1 e-bike only assists while the rider is pedaling and stops assisting at 20 miles per hour. A Class 2 e-bike can be propelled by the motor alone, without pedaling, and also cuts out at 20 miles per hour. A Class 3 e-bike assists only while pedaling but keeps assisting up to 28 miles per hour, faster than the other two classes.
Under Section 380.020(D), the Board of Aldermen limited multi-use trail access to the slower classes: it is unlawful to operate any electric bicycle other than a Class 1 or Class 2 machine on any multi-use trail in the City. Motorized bicycles, defined separately as gas or electric-powered two- or three-wheeled devices with automatic transmissions, are barred from every multi-use trail under Section 380.020(C), with no class exception. Off the trails, Section 380.020(A) lets bicyclists and electric-bicycle riders use sidewalks (except in business districts), pedestrian paths and school grounds if they exercise due care and do not endanger pedestrians, who always keep the right-of-way.
Multi-use trails also close between sunset or 9:00 P.M., whichever is earlier, and sunrise, except with a City Administrator park use permit. St. Peters Police Department enforces the bicycle chapter citywide, and Section 380.170 sets the penalty for any violation of Chapter 380, including the Class 1/Class 2 trail limit.
Violations & Fines
Riders 17 or older who break any Chapter 380 rule, including the Class 3 trail restriction, are guilty of an infraction under Section 380.170 and face a fine of not less than $5.00 nor more than $25.00 upon conviction. If a rider under 17 violates the chapter in an officer's presence, the officer may impound the bicycle or motorized bicycle for up to five days, issuing a receipt to the child or the bike's owner.
