Is it wise to plan a journey in april?

So group of 4 planning to fly in, and stay for 7 days. We want to try to cover the scenic routes in bikes but I'm not sure there will be snow at that time in specific area. We are ok with taking a cab for 2 days to certain areas without missing much on must go places in bikes. Will the sky be amazing in april?, we dont mind the cold just worried about icy roads or rain spoiling our plans.

So do we go ahead and commit to this trip? Do we push it to april end?

Thank you :))
