Hello friend, the truth is that I have tried many bikes, and I have been involved in the subject for a long time, my recommendation to go out and enjoy a ride is a bicycle, with a comfortable driving posture, where the back stays right, and The weight is distributed mainly in the seat. If your plan is to use the bike on asphalt roads, a fine wheel, or a medium wheel, is going to be the best, you do not need a MTB that usually have a heavier road roller. A ride bike, urban with a 700 x 32 wheel would be excellent, if you live in a flat place you do not need too many gear shifts. The simpler your bike, the less maintenance and the lower cost you will have.
