The Saturn leans hard into the moto look: a TFT colour display, a twist throttle, bar-end mirrors and a front light with a horn.
Turn signals and a brake-light taillight make it genuinely street-aware, and the Heybike app unlocks settings and ride data over Bluetooth.

The Bike Cave Verdict
Ben's Take
I haven't thrown a leg over the Saturn on camera yet, but it's one of the most characterful things Heybike makes — a blacked-out fat-tire moto-cruiser with a 52V 1000W hub, an optional second battery for up to 90 miles, full suspension and hydraulic brakes. Mirrors, turn signals and a bench seat push the mini-moto vibe hard. At $1,199 to start it's a lot of hardware for the money; just remember it's a heavy 28+ mph machine, so give yourself room to stop. I'll ride it on camera soon.
