Sun Chaser confirms this accessory for Alpha V3, Nova V3, Alpha V2, Nova V2, Halo, ADO Air One Ultra.
Mounting: This listing includes the Carrier Adapter for the Zenith Relax; it is not a MIK child seat. The confirmed bike pairing still requires the seat’s rack, child-fit and installation checks below. MIK compatibility alone is not child-seat approval.

It can suit compatible e-bikes, but the rack rating, rack shape, wheel clearance and rider handling should be checked before fitting.
