Afaik almost all ebikes do not have regen. If it's a hub motor it's often geared with a one way bearing, and if it's mid drive (getting more popular) then you cant have regen as the chain is not back-drivable.
The efficiency gains of bicycle regen is not high enough and there is added drag of pulling a motor along if you are just pedalling normally. Most regard the trade-offs to be not worth it.
There is one Canadian ebike parts manufacturer that's pushing for regen, and their main reason for doing so is that it saves on brake pad wear.
