Just turned 69 years old yesterday and need help finding a new bike (and probably posting a thread?!) I LOVE riding & want to continue but my needs are changing

Got a Trek Verve 2 ... very heavy bike and need something much lighter to take me into my 70's since I need to lift the bike into my car or down stairs in my house.

Looking for:

Step thru bike

Carbon or VERY light material

Disc brakes

Bike I can ride on both trails and roads


I'm a fairly small woman so will need either a Small or XS -- 5' 2" 135 lbs

Have tried local bike shop but they honestly told me they don't have what I need

Any ideas or suggestions would be very appreciated
