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 $999 to start it's a lot of hardware for the money; just remember it's a heavy 28+ mph machine, so check your local class rules before you commit. I'll ride it on camera soon.
👍 What stands out
- Genuine moto looks — mirrors, signals, bench seat
- 52V 1000W / 1800W-peak hub with real torque
- Optional dual battery for up to 90 miles
- Full suspension + hydraulic brakes
- Sharp $999 starting price
👎 What to know
- Not yet reviewed on camera — verdict and score to come
- Heavy (103–115 lb) — not a bike you carry upstairs
- 28+ mph means class rules matter where you ride
- Single colourway only
