Heybike Seatpost Clamp

The clamp that holds the seatpost at height on Heybike commuter and cargo e-bikes. It is the part to replace when the post keeps sliding down under load, or when the clamp bolt has stripped or snapped. Fitments cover the Ranger, Ranger S, Mars, Mars 2.0, Horizon, Explore, Cityrun and Brawn, each listed as its own variant.

Select your bike from the Fits bike option so the clamp matches your frame's seat tube. A clamp that will not stop the post slipping under load has usually lost its bolt tension rather than needing more torque, so if the bolt threads are still good, try cleaning the post and clamp faces and retensioning before ordering. If the threads are pulled or the clamp body is cracked, this is the replacement. Reinstall with the post at your usual height and check it after the first ride.
