Class 3 e-Bike
The BULLS E-Stream EVO AM 4 is a Class 3 electric mountain bike with a Brose Drive S Mag motor delivering 90 Nm of torque and pedal-assist up to 28 mph. It's street-legal in most states without a license or registration, but its Class 3 status prohibits it from most mountain bike trails in the US, which typically only allow Class 1 eMTBs. It suits off-road riding on private property or the limited trail systems that permit Class 3 bikes. Verify local trail regulations before purchase.
